Wifi blows on 10.5 - Galaxy Tab S General

I gotta tell ya, id absolutely love this thing if it wasnt for wifi issues. This thing drops connection all the time and lags so bad its awful. Done everything I read to do, freezing or deleting apks. Think it would be a home run if it wasnt for the wifi.

I've had mine a few weeks and I've never seen it drop wifi.

Never had a problem with the wifi, but the lag is horrible

Did you messes with your kernel?

I've got an 8.4 but I'm assuming the WiFi hardware is the same??? I've had mine for several months and never dropped a connection (except when my router went down) . I use it mainly on a 2.4 Ghz network at work. In my office I'm on the other side of an elevator shaft from the access point so reception isn't good on any device in my particular location - but it works and even there never dropped a connection. At home I've got it on 5 Ghz and where I typically use it the signal is very strong. On speedtest.net it matches the speed of my desktop PC which is wired into the router....so it's getting all my internet connection has to offer (service level is 30 Mbps but speedtest.net usually shows 32 - 35).
I'm assuming you have already checked the obvious things like signal strength? Does it drop the connection in some locations but not others? Does it make a difference what router or access point you are connecting to? Interference from other WiFi networks or (if using 2.4 Ghz) other devices like cordless phones?
Try installing WiFi Analyzer (free in the play store). It will give you a real time chart of your signals strength for all access points it can detect on both 2.4 Ghz and 5 Ghz. For example in my Culdesac I can see at least 6 other access points with pretty strong signals (all my immediate neighbors). At my office, on the side of the building facing an appartment building on the opposite side of the street, I can see at least 25 2.4 Ghz access points. Amazing how many are named Xfinity WiFi or Linksys . On the other hand, on the 5 Ghz band in my home I only see one access point other than mine.
Try manually setting your router/Access point to a channel no one else is using. Switch to 5 Ghz if your router has it or buy a new router if it doesn't. This band is a lot less crowded, at least where I live. If your signal strength is low in the place you want to use the tablet, try moving closer to the router to see if that helps. If it does, consider moving the router or getting a second router or repeater.

I use to have problems in my home with 2 things.
A baby room monitor - REALLY tore up my wifi all over the house!
A set of wireless rear surround speakers was a problem for about a day. Lucky for me they have the ability to change the channel they use. Wipped out my freq counter, found out where they were and moved them to ch 11. Unit isn't marked as to what 3 channels you can select from. So the freq counter helped me find where they were and where I could put them. After I got them on ch11 I moved the router to ch4 as there was no one using it near by. Problem solved and have no wifi problems at all with the Sammy.... Matter of fact my router sits on a cabinet 6 feet off the floor. I get coverage over my whole .7 acre Ponderosa while listening to music riding the mower!

my wifi seems to drop once in a while too but i think its the crap router i use.. not sure
i also reset my tab and that helped.

Another thing I just thought of that you may want to check.....
Make sure no devices are fighting with each other trying to get the same address on your network. I just went through this last night. Once resolved, no problem.

A lot of this sort of problem can be fixed by going to 5 Ghz - which may mean a new router if you are using a router that isn't dual band. Most of those other devices in homes (and in your neighbor's homes too) are on 2.4 Ghz so there are a lot of things that compete for that spectrum that aren't even WiFi.

No WiFi issues here

No wifi issues here. I was on stock for about the 1st 30 days on the device and have rooted and installed various ROMs since. I would argue that this device has better wifi than other devices in my house, though my router is not AC so I have no comment on AC performance. I do have an issue with N 5 ghz networks not being seen right now, but that is something I induced.

Too many factors to consider but I can say if other's haven't had issues than it's likely something else.
Distance from access point
Access point's distance from other electronic equip.,
Wireless channel
G or N connection
latest firmware on wireless access point
cabling on AP
trying a different Access Point or wireless network altogether (coffee shop, etc)
wireless sucks to troubleshoot. Constantly changing settings until some magical combination works for all of your equipment.
like to connect my Nexus 5 to wireless N I have to set my 5Ghz channel to be on upper or lower frequency band or something- can't remember which it's supposed to be, though. My PSP needs the 2.4Ghz radio set on a b/g mixed setting. That's the only weird wireless settings I've ever needed to actually get specific devices to connect.
if you're looking for advice we'd need to know the model of your router/access point, though I'd probably go look at a forum where people talk about it.

Hi,
I am wondering, if anyone else having this problem...
My best available 2.4 ghz wifi channel is 13 (2472). If I select this channel my tab does not find the wifi anymore ("out of range"). All my other devices are running on channel 13. All other channels working.
Tried it with stock rom + stock kernel as well as with stock rom + latest UpInTheAir kernel, iron rom + UpInTheAir kernel, iron rom + stock kernel, factory reset, clean flash etc...
Can anyone confirm channel 13 is working on this tab?
SM-T805
Thx, brgds!

WiFi issues on stock

I have issues on Wi-Fi with my one where with my Samsung glide no problems . I have a Belkin router wireless N and it normally works fine but with the one I get occasional drops and reconnects. Anyone else have this issue. I am on stock rogers. My Wi-Fi has security enabled as well.

Did you turn on Power Saver and Sleep Mode? Click the Power Saver mode in the Power menu in Settings. You can select what Power Saver controls. Untick Data Connection, and if you want, turn off Sleep Mode as well.
I have noticed some issued. I have the developer edition and upgraded from a nexus 4. There seems to be issues with the One releasing wifi and reconnecting to data or vice versa.
In some cases, i know i am clearly out of range for a wifi network, such as the top floor of my office, yet it picks it up and connects without data since i assume i am out of range. For now i just manually control it as its pretty rare, but fir sure not something i have ever experienced before.

Agreed this is what I am seeing.I have disabled power saving and the other option to turn off data when sleeping and yet periodically the wifi just drops as I am viewing some wifi video streaming. It is weird I switch off the WiFi and use data and all is fine. I do not know if it is an incompatibility with my router. That's why I posted here to see if anyone else is seeing similar issues.
Also is there a way to set a manual Ip? was wondering if that may help as have heard issues of other phones having issues with DHCP via wifi.

I ordered a new AC router and will see if that works better and if I still get wifi drops. I am hoping it is my old cheap router giving me issues.

Well I got the ASUS RT-AC66U and now the Wireless 2.4GHZ works great but the phone will not connect at 5Ghz, so much for AC that only operates at that frequency. I heard other people are having this issue as well from my searches on this forum and the web. Kind of sucks that my router has the latest firmware and still has this issue with this phone. I did notice that there was a beta firmware on Asus's site but I am iffy on trying a Beta Firmware on my Router when all other devices are working great and so is the phone on the 2.4ghz. Great range with this router as well. Sucks that I can not use the 5Gz on the phone though. Tried on 2 other Devices that support 5Gz and it is working great on them. I gave 2 different names for the 2.4Ghz and the 5Ghz to tell them apart, but no go on this phone.

here's my take on the whole wifi thing with htc one. either the wifi chip is too picky or it's too new for the older routers. i couldn't get a wifi to stay connected using my old D-Link DIR-655 router from years ago. All other devices had no problems except this phone so that's a bummer. I then picked up the Asus RT-AC66U and immediately flashed the latest beta firmware. Performance and range is flawless on the 2.4GHz band for this router. 5GHz works as well if i'm close but it just doesn't have the range of the 2.4GHz for this phone so I've been sticking with 2.4GHz.
I actually wanted the just announced RT-AC68U but couldn't wait any longer as there's no eta on the release for it.

I used to have a Belkin Wifi-N router cost me about 40$ on sale and it used to work with my old Samsung but could not connect and stay connected on my One (Single was not to strong on top floor of house as well). It kept dropping WIFI after a few minutes on One and was really annoying. The RT-AC66U works great at the 2.4Ghz and I am tempted to try the Beta Firmware that you are using but I hear it slightly drops the range on the 2.4Ghz and all my other devices (WD-TVlive) are working great streaming 1080P from 3 floors up (Routers in Basement). Question for you, since you flashed the Beta firmware and can connect at 5Ghz are you hitting the 400Mb speed when you connect at close range. If you click on your connected network on phone it shows you the connection speed.

unfortunately with the beta firmware on 5GHz band, the fastest i am able to connect with this phone is around 87Mbps and it still feels slow compared to 2.4GHz. mind you this is me checking the speed by standing right next to the router with my phone. on 2.4GHz the fastest speed i can get is 72Mbps but the range is great. i hope asus is able to release newer firmware that will help increase the speed and range of this router at 5GHz but it's probably not possible. i still think it's the AC chipset/driver in this phone that's preventing the wireless from achieving maximum speed. in comparison, my dell latitude notebook is able to connect at 450Mbps at 5GHz with on wireless N. THat's with the intel wifi chipset which has always been imo the best in compatibility and performance. i look forward to the day when i can rock a smartphone with intel all in one chipset.
I am also connected at 72mb and at 2.4ghz it connects great. I am going to leave it like this. I find the range on the Asus router is amazing. It sure beats all other routers.

WiFi Issues

Hi Everyone
I looked and I could not find info on this issue. I have just used WiFi at home in the past with the Note 3 and it was fine. Here is some history of the changes:
- Old home WiFi was single band wireless N (53mbps) with a second repeater hot spot. This worked well with the Note 3.
- Had issues with the router so I upgraded to a dual band ac router and removed the second hot spot. So now it is just the new router for the whole house.
- Issues now - receive 2 bars at the far end of the house and basic WiFi is OK. Watching You Tube is an issue and it loads, plays for a few seconds, loads more etc.
I don't see a way to tell if I am on ac or wireless N. I was going to try to switch to wireless N and see if that helped but I can't see a way to do this? This router is way faster than my old one so I thought speed would not be an issue. no one else is using the wireless in the house. I would think that 2 bars would be strong enough? I think that wireless N would have a better range so that is why I wanted to try that. I am assuming that I am connecting to ac. Any thoughts?
thx in advance
AC routers have two separate ssid's. One for b,g,n. And another for 5G band. The 5G band default ssid is the same as the other with "5G" at the end. 5G band doesn't have good range, but it has faster speed between connected devices. 5G won't have faster internet unless you have a 100mb download speed. Which is unlikely. So your YouTube issue is either your modem, or a Qos setting in the router. If your router is at default settings it's definitely your modem.
You might be able to get more support on this subject thru a forum for your router, or modem.

why not use your old router from your old home as a repeater? wouldn't that work?

That's called buffering and it's due to low thruput (which is different than speed). It can be caused by low signal strength (due to distance or to the signal haveing to go through too much along the path), noise between the router and the phone, interference with someone else's wifi signal ...
You need at least a couple of apps like Signal Check Lite and Wifi Analytics to see what's going on. Guessing isn't going to give you a solution.

2.4ghz WiFi disappears

My 2.4ghz WiFi at home won't stay connected on my nexus 6 and dissapears from my available networks list. Even if I select 2.4ghz only it dissapears. Don't think it did it with 5.0 that I remember. I use 5ghz in the house but my 2.4ghz reaches outside farther when I'm by the pool or doing yard work streaming music.
All other devices connect to it fine with no issue. Tried messing with channels but nothing. Any ideas?

What rom build and radio are you on? do you have any third party switchers and lan managers loaded on your phone.

Cm12.1, but also did it on the factory image. Does it on both 95 and 98 radio (currently on 98). No third party networking apps.

hmmm. not sure why it's just that channel. Only time i've ever seen 2.4 boot is on Ubuntu 14/15 HP, because hp wifi driver is generic . wondering if it has something to do with poll request. If it's doing it outside by the pool, you might be picking up neighbors strong signal. not a real answer, but a start.
Suggest, dl a wifi signal monitor, and watch the log to see what you were doing when it dropped.

I live in the middle of nowhere, neighbors would need one heck of a router to reach me haha. Used WiFi analyzer and walked my whole property and only saw a bit of one network on channel 8 so I put mine on channel one. It just disappears randomly. I can go to sleep and wake up on lte. Or be looking at the WiFi networks list and it just drop in and out. 5ghz is always there though. My WiFi settings are set to auto not just a specific band. Its super annoying.

well we know it's radio, since it's happening on stock and cm12. and with both radio's. I'd hate to say hardware, but that's what it is pointing too. Sorry. If nothing else is being booted, i wouldn't say router hardware.

I'm thinking its a conflict between my phone and router. It worked fine on 5.0 and the old radios from those builds. And 2.4ghz band at my work is perfectly fine. And we have over 50 access points that I hop around on all day to cover the whole building. So its a combination of my phone hating my router or my router hating my phone. Obviously both devices are fine. Maybe my router is racist? Could be a possibility.
Was just asking to see if anyone saw this issue and found a work around. Be it specific channel, speed setting, hz setting, wireless protocol adjustment etc. Its a netgear wndr4500v2. All the HP access points at work are perfectly fine. May be time to try a different router.
Ahh OK. So now good prob to figure out

Random Slow WiFi problem

So today I started having a strange issue with my Droid Turbo. The WiFi speeds are absolutely abysmal. Everything was fine in the morning. Then I went out for a while and got home around 4, and my phone wouldn't connect to the WiFi. I finally got it to connect, but nothing was loading, so I ran a speed test and saw that I was getting < 1Mbps down and up. This was really strange because I usually get 50 up and 25 down. All my other devices work, including 3 laptops, 2 iPhones, a note 2, an iPad, and a Chromecast. My router is an ASUS Google OnHub, and I used my Turbo to set it up. LTE works fine. I've already tried the basic steps, including a cache partition clear, but nothing is working. Any idea what's going on?
Edit: so I did some testing and found out that if I hold my phone right up to the router it will give me the full speed. Once i move a few feet away it drops significantly. However, my phone still reports the signal strength as "excellent". I also tried this with a different network somewhere else, this time with a Cisco router, and the results were the same.
My wife's phone had all sorts of issues recently with Wifi on her Turbo. Longer story short, we found it was related to interference with her bluetooth (also on 2.4GHz) and possibly interference from neighbors. I'm not sure what changed, but I had her on 2.4GHz and she had all sorts of issues. I moved her to 5GHz which has resolved the issues (though it's much shorter range now, too). Turning off bluetooth seemed to help... but it didn't resolve it completely. The phone would say it was connected, but it wouldn't actually function online. We do live in an apartment complex with LOTS of 2.4GHz users and interference, so something in someone else's apartment may be interfering... obviously I'm not going to be able to figure that out with so many neighbors! Also, we have an Asus router... so that's why I figured maybe something is up with Asus's code or something, too... making more sensitive to interference?
Update: So I noticed that my phone was only connecting to the 2.4 GHz band, which is strange because everything else would connect to the 5GHz band. I messed around a bit and I found out that the range was just too short. When I placed my phone on top of my router, it would connect to the 5GHz band. As soon as I walked away, it would disconnect. So this leads me to believe that the wifi antenna inside my phone got messed up somehow.

Home Network Expert/Engineer Help Needed

Here is how I have my home network setup:
Uverse Gateway (Wifi 2.4GHz SSID=2wireXXX, currently off) (NAT/router 192.168.1.X)(6Mbps data plan)(other Uverse TV boxes are connected via coax)
---Netgear R6250 AC (Gigabit) (as Wifi Access Point 2.4GHz SSID=tesla, 5GHz SSID=tesla5g)
------Gigabit Switch (to TV/BluRay/laptop/etc)
~~~~Wifi Devices (lots of android phones/tablets/roku/etc)
---Netgear Arlo Hub (dedicated wifi to 4 cameras)(seems these like to force themselves to same channel as router, makes no sense?)
---SmartThings Hub (Zwave 900MHz)
---AT&T MicroCell (currently off)
I am getting some dropouts in Wifi lately and looking for some help to see if I have everything configured/connected in most efficient way. 2 kids are usually on tablets playing Minecraft/NBAlive/watching Youtube cooking videos Son has been complaining about wifi a lot lately. I don't think it has been too bad, but I also notice spinning icon on ipad title bar near Wifi occasionally. I've been doing speed tests via google, when everything is quiet I get 6-8Mbps. One kid on youtube drops it ~2Gbps. Occasionally when I get that spinning icon, speed test only gets 0.5Mbps for unknown reason. Recently when this happened I jumped on cat5 connected computer and immediately got 7Mbps.... uverse seems okay.
Home is 2 story, wood, with full basement. All of this (except the switch and wifi devices) is in one cabinet at North end of my house, near main living area. Kitchen, Bedroom are on south end of house (which is about 55feet) so get poor coverage there (phone charging area and bedroom Roku have por signal). Obviously moving it all to the middle of house would cover everything better, but don't have a good spot to place everything at middle of main floor. I have a basement with drop ceiling that I could relocate some stuff too but need to pull cat5 and power there, just under first floor decking.
I had the kids tablets and older devices on 2.4GHz and only a few newer/faster/work devices on 5GHz. Moved my son to 5GHz recently, too soon to tell if it helps his issues.
-Do I have too many devices in one cabinet (as far as number of radio transceivers)? Heat doesn't seem to be problem, not sealed and doesn't feel too hot.
-Would it help to move R2650 to middle of house and turn back on the Uverse wifi? Put kids on 2.4GHz. To minimize re-wiring, I'd probably change the devices to this order: Uverse---GigabitSwitch---NetgearR6250; I think this maintains Gigabit speed inside house.
-I also have another even older Netgear 2.4GHz B(or G?) router, should I put this at other end of house all on same SSID? So I could have three 2.4GHz access points which all appear to be same network (?????). Then just have 5GHz for the important devices (my wife and I).
-What are some ways to monitor/debug this??? I'd like an app to see which devices are using most data throughput at any given moment and total per day. Tried Netgear Genie App but it is pretty limited. Is the only way to use router with custom firmware?
Thanks in advance for any advice or pointers to help!!!
