Can't connect my N1 with Linksys router

Hello
My N1 can connect easily to all kind of wifi routers and modems without problem but not with my fitness club's one, they have a Linksys N160.
My N1 can detect the signal,enter the password but then it's stucked with the message ''getting ip...''
Where is the problem? is it a know hardware or software compatibility stuff?

Sometimes rebooting the wifi router helps. Also make sure that when the guy over at your fitness club reboots the router you don't have the wifi of the club saved. delete the saved wifi profile, reboot the wifi router and then try. Cheers.

Already tried it several times. I saw that OS4 of iphone/ipod have the same problem with router enabling Wireless-N, I will ask him to limit the router to B/G

I also had similar problem with Linksys WAG54G2 (at latest firmware). Then I changed to much cheaper adsl router, TP-LINK WD-W8960N and no more connection problem.
Sent from my Nexus One using XDA App

I had problems using my Nexus One on my SMC Barricade 802.11b/g/n router when 802.11n was enabled. Turned it off; problems were gone. I don't think that works well yet, though some people have said otherwise. Could be a router-specific issue.

Ok so it's a WAG160N to be specific.
He tried to use mixed B/G instead of mixed (which would imply N too) but it still stuck at getting ip...
I told him to throw this router in the garbage because anyway SE and HP mobiles can't connect too,but he said he would do it but his boss will never accept to pay a penny more

My parents had a router that did exactly the same, my phone got stuck on Obtaining IP, whilst the missus 5800 connected and broswed just fine.
It was a crappy old thing and they replaced it the other week, now I can connect and browse just fine.

I also use a linksys WAG160N.
bought a nexus one, could not for the life of me get an internet connection.
turns out dns on router is poofed, so i just set DNS from my isp manually on the nexus one together with a static ip and booya interent at full 802.11n speeds.
sometimes its the simple things.

This sounds similar to when I set my router to channel 13 or whatever the max was on it. My N1 would only sometimes get a connection, but would eventually drop it and stay off. Solved it by selecting a lower channel (WifiAnalyzer suggesten channel 1 as the best alternative to channel max) on the AP.
I can see that in CM6 nightly that I have since started using I can choose regulatory domain, and thereby open up channels previously blocked. If you can't change anything on the AP this might help you solve the problem on your end.
So suggestions if none of the posts above me provide a solution is to run WifiAnalyzer and see how the channel-graph looks.

Dummies' Guide to Diagnosing Intermittent Wifi on NC - fixed in BN1.3

This is a compilation of threads found on this forum as well as the BN forum. I thought having it in one place will help.
Edit: problem may be BN NC. See last paragraph
The NC is the first device that I have encountered that had intermittent wifi problems. At home, I have a mixture of Macbooks, iPod, a Viewsonic G Tablet running Android 2.2, desktops running Windows 7 and XP using various brands of USB wireless adapters and have NOT had any problems using 802.11n with WPA2/AES encryption.
From other threads: "As always, everything in this guide is completely at your own risk, I am not responsible for you messing up your device further nor am I responsible in the event that your Nook Color explodes and kills your cat, grandma, etc."
Intermittent Wifi Connection:
This is the issue where your Nook connects to Wifi and then after a few minutes the connection goes away. Typically the NC shows wifi as connected or perhaps connected and testing.
There are five variables that can cause intermittent wifi connections:
-your router
-wifi type 802.11b/g/n
-encrytpion
-wifi frequency 2.4ghz/5ghz
-NC ROM
-NC operating system
In many cases, this is due to 802.11n wifi. A digression: Wifi comes in manner flavors; 802.11b, the first standard; 802.11g, the second; 802.11n the latest standard. These flavors have to do with the physical wireless router.
In addition to the hardware, there are variations in encryption of the wifi signal: WEP, WPA, WPA2 with AES or TKIP. WPA2 with AES is the most secure. Look it up on Wiki for more details. And of course the
OS the NC is running.
In many cases, the NC will NOT connect reliably with 802.11n. I have a Dlink DIR-615 V2 wireless router and when set to 802.11n with WPA2 with AES, the NC connects but after a few minutes goes into a state of "testing connection". Setting the router to 802.11g only fixes the problem. An easy test is to go into Youtube and watch a long video. Most likely, half way through, you will loose the connection.
At work, we have a high end multi-access point Meru networking running unencrypted wifi 802.11n and I have this problem. So this may indicate a driver problem with the NC.
The Fix:
Go into your router's wireless. Select manual setup and find 802.11 mode or something to that effect. On my router, I have a choice of "mixed 802.11n, g, b", "802.11n only", "802.11g" only. Selecting 802.11g only with WPA2/AES fixes it for me.
Interestingly the NETGEAR WNR3500L-100NAS 802.11b/g/n seem to operate reliablely with the NC using 802.11n.
One post indicates that settting encryption to TKIP also fixes the problem.
http://forum.xda-developers.com/show...72&postcount=6
However, using TKIP opens up a hole for hackers
http://en.wikipedia.org/wiki/Tempora...grity_Protocol
One solution on the nookboards and BN forum also suggested turning off 802.11n
http://www.nookboards.com/forum/index.php?topic=5669.0
http://bookclubs.barnesandnoble.com...-Problem-quot/m-p/770856/highlight/true#M3295
If you are having problems, the following information will help in diagnosing the problem:
Router brand and model number: eg: Dlink DIR-615
802.11 mode: b, g, n?
SSID visible?
Encryption: no or if yes: WEP, WPA, WPA2 TKIP/AES\
NC Rom: 1.0.1 or 1.1
NC OS:
I will try to update this guide periodically. Moderators: feel free to delete this thread if it is redundant.
Edit:
BN has acknowledged there is a problem with certain routers. From my own experience, there are many more routers that are incompatible with the NC. My assessment is that it's a driver in the BN. I have a Gtablet running 2.2 with no problems.
http://bookclubs.barnesandnoble.com...ssed/m-p/1030918/message-uid/1030918#U1030918
From BN Administrator: "In general, wifi issues can continue to be fixed by following the troubleshooting guides posted in the FAQ and in other posts. We *are* continuing to investigate reported wifi issues with certain routers that have had issues reported. At this point, we’ve investigated the Belkin F5D8231-4 and found an issue introduced with Android 2.2. We have a fix that will be included in the next release, but do not have a workaround for users. We are also investigating other routers (including the DLink DL- 624 and Westell 327W), but do not currently have a fix for them.
Please continue to post here if you encounter further problems and NOOK_Engineer and I will work together to investigate further."
EDIT 9/7/2011: After I updated to BN1.3 and then rooted with, wifi connects perfectly with 802.11n both at home and work. Work wifi consists of multi-point 802.11n. Note that this is with Dalingren's froyo 9/1/11 kernel with the BN 1.3 source drop.

Thanks for this! Do you have any ideas about intermittent wifi ONLY when on an Adhoc network from my Droid? I had no wifi issues under Rooted 1.1 but when i went to internal Froyo 0.6.6 it is almost unusable. I have upgraded to 0.6.8 and it is still not working correctly, it keeps loosing the IP or pausing the connection.

Done some digging on this, and the issue is that my NC can see either the G or the N channel from my router, but not both (even with different SSID) when G is at 2.4 and N is at 5Ghz. It will only see N on 2.4 Ghz. bah.

I like the idea of putting it all together as it took me awhile to figure it out.
FYI, my wireless modem is:
D-Link DIR-655
On WPA/WPA2 TKIP
Interestingly, I made a setting change to set the wireless mode to only n & g modes. This stopped my nook from getting any wireless till I changed back to n,g & b. Not exactly sure what this means other than it could a router specific issue but good to keep the info in one place considering it is hard to track.

Not sure of this but if it works with Rooted 1.1 but not Froyo 0.6.6, most likely a Froyo issue.

The wifi chip in the NC WL1271 supports only 2.4ghz. Interestingly the kernel reports the chip as WL1273 which does support 5ghz.

I don't think the original post regarding 802.11n being an issue is correct. We have two access points running 802.11n and have no issues with the Nook Color. I have them set up to operate 802.11n at 2.5 and 5 Ghz. I connect the NC to the 2.4 GHZ radio and use the 5 GHz for my laptops. I am using a Netgear WNDR 3700s.

@jerrykur - Well that explains that. I'm trying to sprint up the learning curve as fast as i can with this wonderful device... sometimes i miss things ;-)
@Zhousibo - I suggest you grab "wifi analyzer" from the market. It's an invaluable tool for tweaking your network. For instance, it lets you see which bands are cluttered and clashing. In my neighborhood everybody (i.e. about 20+ networks) is on the default channels 1 or 6. I can literally watch as one network pops up above the noise and drops out again. In exactly the same spot in the house we have a several dB stronger signal if we move the network to a clear channel. Also bear in mind that the encryption and frequency are two totally different issues. I would vary one at a time and look at what wifi analyzer is telling you - my guess is that only adjusting frequency will affect signal strength and signal drop outs. I would also start with the simplest working setup and add or remove optiosn one at a time, watching what happens to the signal. Once you have that problem fixed, then worry about authentication issues (i seriously doubt this is the problem, i've tried all combinations of authentication on my router and they all work - just go for the most secure!)

BTW1: in wifi analyzer you can view signals as a graph in time which will let you see signal drop outs (i.e. let's you watch what is coming into the machine), combined with fpga_guy's suggested method (watching you tube - so following what is coming out of the other end of the software, so to speak), will let you nail down where the glitch is - in the network or in the machine. Similarly you could ahve two devices whatching the same or different youtube sources, if they both fail at teh same time it is a network or even further down the pipe (e.g. ISP) issue.
BTW2: if you are using VOIP, then QoS in your VOIP box could be responsible for a lot of this depending on how your wired network is structured.
BTW3: I should have explained my motivation behind these posts - I just have not had any problems with dropped connection on the NC (other than all the problems with waking in rooted ecalir) on either G or N networks. I can pretty much move around town from rememebred netweork to remembered network and almost always be connected. I'm actually extremely impressed with how well networking DOES work on this machine, especially in Frroyo. BUT my home network is pretty complex and very busy (media center PC, streaming to at least one device most of the time, multiple PC's wireless printer, wired NAS, etc) so has had a lot of fine tuning... So I'm doubly impressed at the lack of drop-outs given this deployment... hence my advice to eliminate network issues first.

Here is an update on my testing of the NC with various routers. My ipod touch, HP DV1000 laptop running Windows XP connects to every router listed without problems. This indicates either a chip or more likely an implementation problem with BN's driver to the TI wifi chip.
NC (ROM 1.1 with Auto-nooter 3.0.0) works with:
Netgear WNR3500L running 802.11n with DD-WRT WPA2/PSK
DLINk DIR615 runnign 802.11g with WPA2/PSK
Work wireless running 802.11g (router unknown)
NC does NOT work with
Sites with hidden SSID
DLINK DIR615 running 802.11n
Sites using WEP with 128bit encryption
NC connects on boot with sites using WEP 64b encryption - FC after resuming from sleep.

@bonobomidwest
My only thinking is that the NC wifi driver is not as robust with the settings (maybe it is settings, firmware, hardware, not sure).
Interestingly, I spent a bit of time away from my home network which is where I have had no problems since I made the original change (FYI, I recently upgraded from Autonooter 1.1, to Nook Froyo 0.6.7 to NF 0.6.8 and have been stable since the change). I stayed at my folks for a week as am living overseas and they have a Belkin router (can't remember model but I gave them this and was pretty good for it's time). I had issues where the wifi had problems connecting after the screen had timed out so did not use the NC as much as I wanted. I also had problems with the wifi on Galaxy S on this network even though I changed the settings.
I haven't done a scan where I am living now but it should be more than where my folks are due to living in an apartment as opposed to my folks house.
I'm at the stage where my network is not 'broke' so not actively looking to fix it but all my devices NC, Galaxy S, PS3, PSP, etc, are all working now - only the NC has had the most problems with connecting to wifi but have been resolved.

I'm having trouble connecting to an 802.11B (yes B) 11Mbps unencrypted router on the bus I commute to work with. Not sure of the brand or model. Wireless status says I'm connected, but testing. I try to browse the web with Dolphin HD, but I never connect. My iPhone connects to the bus' same router without problem.
However it connects just fine to a Linksys WRT610N v2 (flashed with TomatoUSB) running 2.4Ghz N, 40Mhz bandwidth, WPA2/AES
Running Autonooter 1.1, but given what Zhousibo said in the previous post, I'll try out NF 0.6.8.

Any new ROMs help fix WPA2 connectivity problems?
Just bought my NC and flashed a great Froyo ROM on it.
(The first one I bought had obvious hardware issues, 1bar of wifi signal in the same room as my router. Brought it back same day and had it replaced, immediately better. A known reported issue with some faulty NCs).
Had the same issues with wifi connectivity as described here and everywhere on the net. Essentially, it will connect onto the router with N speeds, but is completely unable to access any internet.
I have a great router (it can broadcast 3 separate SSIDs) but I think it doesn't play nice with the nook. So, it was great up until now =P
Router brand and model number: Buffalo WZR-HP-G300NH
802.11 mode: n
SSID visible? yes
Encryption:
SSID1: (WPA+WPA2 mixed TKIP/AES) OR (WPA+TKIP)
SSID2: WPA2+AES
SSID3: WEP (yuck)
The Nook only fully connects to the WPA+TKIP mode (on SSID1) or WEP. The supposed mixed mode setting probably isn't quite as mixed as advertised. The Nook works fine on WEP, but I hate the fact the security is so poor with WEP.
I'd have no problem dropping the SSID1 settings to WPA security, except for the loss of n speeds. Part of the 802.11n specs (has to be WPA2/AES, or NO encryption--not an option). My DVR/home network is on that ssid, so I don't want to lose my n speeds.
So my question is do any other ROMs here help fix the WPA2 connectivity? I know lots of people swear their NC works fine with their WPA2 router, but I suspect their router is just more capable and is switching to WPA-TKIP discreetly.
This is not the same reported problem as having wifi cut off in sleep mode.
EDIT:
Oh, I just realized as a work-around I could put my home network on SSID2, and just the Nook on SSID1.

Get the right router...
Of course I can't speak for others, but my experience with this problem was that this problem was entirely router related. The rooted NC was very slow (to the point of almost unusable on the internet) from my home Netgear WNR834B Wireless N router, regardless of the speed settings, the channel or the security settings. I was able to experience much faster speeds (allowing UTube and Pandora to function properly) at a friend's home (generic Verizon DSL router) and at 2 public wifi locations. As a result I tried another Netgear WPN824 Wireless G Router with the same results as the other Netgear device.
Then I borrowed a couple of Linksys routers from a friend and tried them. The first, an older WRT54GS Wireless G lacking current security standards and then a WRT150N Wireless N. Both worked fine with the NC, allowing full access, with the latter operating at N mixed B, G and N speeds and WPA2 Personal security.
I am very pleased with the results after a few frustrating hours of trying to diagnose the problem. I hope this information is helpful to others. My friend and I will doing some router swapping. I may not tell him about how great the NC is!

Or maybe the NC?

Yep.. no doubt the right router will work with NC. But at home and at work the NC is the only device having problems. I have no luck in convincing my company to swap out 45 routers so my NC can work

I have similar issues. I can't use the internet reliably on my Nook Color or my EVO on my home router unless I'm running WPA+TKIP. I would prefer not to have my router setup this way though because of the security concerns and it not being much harder than WEP to crack.
Guess I'll just stick with WPA2+AES and look for another solution...

just to share some experience that hapenned to me:
In France we have an Internet box (wich is basically a router) that deserve 2 wireless network. One public shared with all user from the same Internet provider and one private for home.
At first my nook only saw the public one (wich is not really fast). The private one was not visible (or just flash in network tools on nook).
After some investigation i change the Wifi canal (from 10 to "automatic"). After that, no to see it and connect (if you forget the nook "special sleep policy")

Please give an update after you exchange your NC. I suspect is the wifi chip drivers and not a bad NC.

[Q] Strange wifi problem

Hello everybody,
I've a very strange problem with my wifi: Sometimes if my Kindle Fire HD is in standby it seams to block all other devices connected on the same band as the kindle. When i Switch on the kindle then, everything goes back to normal.
If I connect my kindle to the 5GHz band and it goes to standby, all devices on the 5GHz band doesn't work after a random period of time. They are connected, but cannot even ping the router. Devices on 2,4GHz are working normal. When I switch on the kindle, the connection of the other devices immediately starts to work again.
If I connect my kindle to the 2,4GHz band, the same happens for the 2,4GHz devices and the 5GHz devices are working normal.
My router is a Netgear WNDR3800. At first, I thought it's a problem with the router, so I've done a factory reset on it already.
Someone else experience this behaivor and/or have a Resolution/Workaround for this?

Yes, this is a known Bug when running firmware older than 1.0.0.38. You need to upgrade to Firmware
Version Number 1.0.0.40, you may obtain the latest Firmware from Netgear:
http://downloadcenter.netgear.com/en/Disclaimer.aspx?redirecturl=http://netgeardownload.registria.com/single_page_registration?product[sku]=wndr3800&download_url=http://www.downloads.netgear.com/files/GDC/WNDR3800/WNDR3800-V1.0.0.40.zip
Download WNDR3800-V1.0.0.40.zip to your desktop, extract to WNDR3800-V1.0.0.40. Inside the WNDR3800-V1.0.0.40
folder will be the latest firmware. You will then login to the Netgear WNDR3800 through a web browser. The
default address is usually http://192.168.1.1/ or http://www.routerlogin.com/ the default username is admin and
the default password is password. If you changed the password, use whatever password you setup. Once you
are logged into Genie Basic, you need to Select Advanced > Administration > Firmware Update. Then click
on Browse, selecting the file file inside WNDR3800-V1.0.0.40 ending with .img
WARNING!
When uploading firmware to the router, do not interrupt the Web browser by closing the window, clicking a link, or loading a new page. If the browser is interrupted, it could corrupt the firmware.
When the upload is complete, your router restarts. The upgrade process typically takes about 1 to 3 minutes.
If this does not solve your problem, respond back and I will help you to change the router to 802.11b/g/n only.
What is your maximum download rate of your ISP? Is it greater than 54Mbps? Usually not, so I find 802.11b/g
to be more stable and actually faster since the router Processor does less work, thus is able to pass packets
faster than 802.11n. The limit is rarely the ISP, it is usually the router that bogs down the traffic.

Hi,
thanks for your response.
My Firmware is 1.0.0.40 already... My ISP download rate is 100MBit/s, I bought the router because of this. I've never had a problem with it until the kindle joined my network
I not really sure if you understand my problem, because you talking about router processor load and turning off 802.11n. It's also hard to explain for me, because my native language is german and the problem is really stange to me (I learned network administration, so I've knowledge about networking).
So, I try to explain the problem again
- Kindle is in standby
- After a random amount of time, no other device on the same wifi band (like the kindle, 5GHz) is able to transfer data to the router. Devices on 2,4GHz are working normaly at that point
- When I turn on the kindle now, the problem goes away (Until it goes to standby and a random amount of time passes).
- When I turn off the wifi of the kindle the problem completly goes away, so the problem seams to be the kindle (although it should not be possible for a device to block data transfer when it is in standby, maybe it's a power-saving feature that the kindle uses and all of my other devices does not and the router cannot handle the power-saving feature correctly. But this is only a thought)
I've no problems with my download speed or something. It's "only" that sometimes the kindle starts to block all data transfer (on the same band) in my wifi network when it is in standby.
[EDIT] But I will try if turning off mixed mode helps.
Regards,
Dennis

http://downloadcenter.netgear.com/en/Disclaimer.aspx?redirecturl=http://netgeardownload.registria.com/single_page_registration?product[sku]=wndr3800&download_url=http://www.downloads.netgear.com/files/GDC/WNDR3800/WNDR3800-V1.0.0.40.zip
Download WNDR3800-V1.0.0.40.zip to your desktop, extract to WNDR3800-V1.0.0.40. Inside the WNDR3800-V1.0.0.40
folder will be the latest firmware. You will then login to the Netgear WNDR3800 through a web browser. The
default address is usually http://192.168.1.1/ or http://www.routerlogin.com/ the default username is admin and
the default password is password. If you changed the password, use whatever password you setup. Once you
are logged into Genie Basic, you need to Select Advanced > Administration > Firmware Update. Then click
on Browse, selecting the file file inside WNDR3800-V1.0.0.40 ending with .img
WARNING!
When uploading firmware to the router, do not interrupt the Web browser by closing the window, clicking a link, or loading a new page. If the browser is interrupted, it could corrupt the firmware.
When the upload is complete, your router restarts. The upgrade process typically takes about 1 to 3 minutes.
If this does not solve your problem, respond back and I will help you to change the router to 802.11b/g/n only.
What is your maximum download rate of your ISP? Is it greater than 54Mbps? Usually not, so I find 802.11b/g
to be more stable and actually faster since the router Processor does less work, thus is able to pass packets
faster than 802.11n. The limit is rarely the ISP, it is usually the router that bogs down the traffic.

Netgear WNDR3800 - Bug in Mixed Mode

Hi,
thanks for your response.
My Firmware is 1.0.0.40 already... My ISP download rate is 100MBit/s, I bought the router because of this. I've never had a problem with it until the kindle joined my network
I not really sure if you understand my problem, because you talking about router processor load and turning off 802.11n. It's also hard to explain for me, because my native language is german and the problem is really stange to me (I learned network administration, so I've knowledge about networking).
So, I try to explain the problem again
- Kindle is in standby
- After a random amount of time, no other device on the same wifi band (like the kindle, 5GHz) is able to transfer data to the router. Devices on 2,4GHz are working normaly at that point
- When I turn on the kindle now, the problem goes away (Until it goes to standby and a random amount of time passes).
- When I turn off the wifi of the kindle the problem completly goes away, so the problem seams to be the kindle (although it should not be possible for a device to block data transfer when it is in standby, maybe it's a power-saving feature that the kindle uses and all of my other devices does not and the router cannot handle the power-saving feature correctly. But this is only a thought)
I've no problems with my download speed or something. It's "only" that sometimes the kindle starts to block all data transfer (on the same band) in my wifi network when it is in standby.
[EDIT] But I will try if turning off mixed mode helps.
Regards,
Dennis

eisbaer82,
We are Network Engineers with over 30 years of experience. I really do understand your problem, we have seen it on
several Wireless Routers when running "Mixed Mode". Factory reset never solves the problem. It is my fault for not
including more detail with the last response, sorry I was in a rush. Since you have an awesome ISP and are running
100Mbps, you are correct 802.11n is your solution. To explain the problem, when a device falls a sleep, it is suppose
to release the 802.11n signal, falling a sleep. The problem is the Kindle falls a sleep and locks the 802.11n single in
an attempt to "keep alive" the WiFi Signal. What some routers do is detect this attempt to lock the signal and then
isolates the lock or plain disconnects the signal so it does not effect other users. The Netgear freezes when the
Kindle falls asleep and the locks the signal. This is a simple explanation to a complex problem. Here are your
solutions:
1. Buy a Cisco Aironet Access Point, not Linksys but Cisco. They cost about $600 USD
2. Change the router mode to 802.11n Only but this will only allow 802.11n users and may
not solve the issue.
3. Go to Google Play Store, download and install Juice Defender Ultimate . Then setup the Power Manager to Turn Off WiFi
when the Kindle sleeps.
Take care.

I see no setting in my router for this. Maybe with DD-WRT?

I think this will be the best solution for me
Thank you,

Dennis,
I completely understand, we have to keep the wife happy! :good:
DD-WRT is a Linux-based firmware for wireless routers. It is compatible
with several routers, most notably the Linksys WRT54G series (including
the WRT54GL and WRT54GS). As with similar projects, DD-WRT is a
third-party firmware designed to replace the firmware that ships
pre-installed on many commercial routers. This is done for a variety of
reasons, including the addition of features which are not typically included
in a manufacturer's router firmware. Having said all this, I would try it
since DD-WRT handles the Mixed Mode differently than the stock
Netgear Firmware. Try it!

Hi,
Having the same issue with my cheap TP-Link TL-3220 (Atheros AR9285) running OpenWRT. After some days of KFHD being connected to WLAN, the router stops accepting wireless connections. Switching from mixed mode to pure 802.11g doesn't help, but after i restart hostapd it works back again, so i guess that the problem is with it. Tried to do some debugging, but failed -- hostapd doesn't provide any info when the problem occurs, it doesn't even report about connection attempts.
To avoid it i just disable Wi-Fi when the tablet isn't used. Besides it saves battery a lot .
UPD: Just remembered that i had the same problem with parents' ZTE W300 which the same Wi-Fi chip, and the OP's Netgear WNDR3800 has some Atheros wireless chips too. Looks like KFHD has such problems with Atheros.

buggerm,
You nailed it, the Atheros chipset has the issue, although there are some Open Source packages that are
able to solve the issue through software with different methods of "lock" and the "timing". You are also
correct that disabling the WiFi is a solution, this is why we recommended Juice Defender Ultimate. This
application automatically disabled WiFi when the tablet goes into Sleep Mode. Thank you for the feedback.

Anyone getting wifi issues? I stay connected but can't pass any traffic

I have been having issues where i am connected to the wifi but the device stops passing any traffic. I have fing installed and i can't ping any other devices on my network. I know its just my phone because i have my work phone and tablet connected to the wifi and they still work fine browsing webpages, watching movies etc while the droid turbo can no longer communicate with the local lan or out to the internet. If i switch the wifi off then on again it will reconnect and then work normally. I can then ping devices on the local lan and access pages on the internet. This has happened a number of times now since i got the device.
Edit: I just updated the phone and still get the issue. I have a cisco WAP at home, we have cisco WAP's at work which i will test tomorrow. If this thing still has issues i am just going to swap it out for a Note 4.

Check this out:

I've been seeing issues with Cisco wlans too.
Sent from my XT1254 using XDA Free mobile app

so it looks like it works good at work, something with my home cisco ap and this phone as all other devices at home work ok.

Yeah this phone does not seem to like my router for some reason. Keep in mind I'm not a networking expert, but I've tried every combination of options and settings every which way from Sunday and I just can't get the thing to work. When I do connect the phone to my wifi it kills the the connection on every device in the house. At first I though it was just a wireless thing, but even the downstairs computer which is plugged in directly to the router doesn't work. Then as soon as I disconnect the phone every device works again. I thought maybe there was too many devices, so I disconnected all but the downstairs computer, still had the issue when I connected the Turbo. I've tried just turning off the WPA2 and just having an open system, I've tried connecting the phone using a WPS pin (This one actually worked for a good 5 minutes before crapping out and hasn't worked since). On the advanced options of the phone I tried an automatic IP as opposed to the default DHCP setting (This also worked for a good 5 minutes before not working ever again). I've tried limiting it to just one frequency band. I have tried so many different things and I just cannot make this phone work on my router. And I know it's my router because the phone works fine at work.
phone: Droid Turbo
Router : Asus rt-ac66r

yup within ten minutes of getting home, the device no longer passes traffic. My work S5 still works fine at home and so does my samsung tablet. The device worked on wifi all day at work on our enterprise wpa2 network no issues. I tried doing static ip at home, changing to 2.4 ghz, trying new ssid. Not sure what else to do with this thing...

Not just you
I posted a comment on Motorola's forum where people are discussing their wifi issues... And my work around. I currently beleive its a software issue and can be fixed via update. Also, today I found (it appears) that the longer the phone goes without a reboot, the shorter amount of the it appears to go with out needing the wifi card reset.

My work around fix...
First, over night my wifes phone now behaves just like mine. It now connects to wifi and after sometime passes it no longer passes data (but stays connected). I needed a way to auto disable/enable the card... I installed Tasker. I have it set to check every 15 minutes, if the phone is connected to WiFi, to disable then enable the WiFi card. I use WifiMatic to enable the wifi card when the phone is connected to the cellular tower that is near my house. (Doing this by GPS uses more battery power...) Using Tasker with the rule to verify its connected to wifi first helps not enabling wifi if its nit needed and lets WifiMatic enable/disable it as needed.

[Q] this is one of the weirdest things I've ever encountered

I use an ASUS RT-N16 w/dd-wrt as my house router. I routinely have 4 devices on its wireless. This is the scenario (which has only just started happening recently):
my wife will connect her S5 to the WiFi at home
the S5 will report connected
every other device on the WiFi that is handy (haven't checked if it happens to my Roku) will be kicked off the WiFi
the S5 will be disconnected
I will have to manually reconnect my other devices, which report an "authentication issue"
The other devices in question are: my Optimus G, my Shield Tablet, our Acer Win8 laptop. Signal strength is not an issue. I have tried:
setting the S5's WiFi connection to our router to a static address
resetting the router to factory default
changed the channel on the router's WiFi
disabling the router's ACK timing
changed the router's WiFi mode to NG-Mixed
Has anyone ever encountered anything like this? Definitely one of the oddest issues I've ever had the "pleasure" of dealing with.

That is weird. I have all sorts of stuff connecting to my WiFi. I use a WD router that has worked extremely well. I would suspect something wrong with the router.

Sometimes routers go bad like any other computer part. Do you have another router to test with your setup?
Looked at some of the reviews of your model and some people had major problems. It has a two year warranty, perhaps get an RMA if still time left. Of course flash it back to stock.

I got the suggestion from elsewhere to create a guest network for her. DD-WRT's got the ability to create a fully isolated guest network, but I only had to create a new wireless vlan for her (bridged, even) & she's happily connected on her own little space (& I'm still happily connected on mine).
More of a workaround than a solution, but hey...

Nicely done.

Update!
My wife took her S5 w/her down to a girls' weekend getaway, & she had to turn off her WiFi while she was at the house because, you guessed it, she kept kicking every other client off of the network!
I'm happy at home w/her on a separate WLAN, but I really do wonder wtf's going on w/her phone...
