WLAN turning on by itself....

Hello everyone!
Just moved from a P3600 to the P4550 and noticed something strange twice in the last 4 days. When I looked at the display in the morning (phone and WLAN were off overnight.....hardly ever turn on WLAN, as I only use it when travelling) I found that WLAN had switched itself on sometime during the night. What gives?
Any ideas would be greatly appreciated!
Thanks!

This happens to me also if:
(1) ActiveSync is set to "as items arrive" (i.e. push)
(2) There is no phone signal.
Apparently AS looks for the Exchange server, and not being able to find a phone signal, turns on Wifi to see if it can connect like that.
I suppose this will also happen if you have AS set to poll mail at intervals. When the interval time arrives, I guess AS will want to go online and - not being able to use the phone signal - will turn on Wifi.
Very annoying as it drains the battery. It does NOT turn Wifi off after a while.
Oh well.

Oh - an afterthought: in CONNECTIONS I have set both programs accessing the net and programs accessing a private network configured to use MY WORK NETWORK. Don't know if fiddling around with that may stop AS turning on WifI.
Should you find a solution, please post coz I would like to fix this bug/feature too.

Hmmm.....if this theory is correct then going to flight-mode instead of just turning the phone off - should effectively not allow any kind of connections.....will check tomorrow....

The hot-spot open wifi problems

My wifi works as a charm connecting to my home router and most networks.
Some networks, however, disconnect me after ive been connected a few minutes and after that, I cannot reconnect to the same network without performing a soft-reset.
Signal is full strenght and the networks with issues are open networks without any passkey or such, i.e., they require only that you enter a login and password at a login webpage. These are "hot-spot" networks so to say, such that usually exist at airports, hotels or as in my case, the university.
Ive been searching this forum 10 times and read perhaps just as many threads about different wifi issues. Power consumtion is set at "best performance".
What happens is the following:
-After a soft reset, the kaiser connects me to the correct netowork and says "connected".
-I login at the webpage
-Start surfing for a while. And after a few minutes, I am disconnected.
-When trying to reconnect, it says "connecting" and then jumps over to "availible", where the phone immediately tries to connect to another network.
My thoughts about the problem:
1.) It is not the networks fault as I can connect to it after a soft-reset.
2.) I believe that it is something ugly written in the registry or in some sort of cache, which is cleaned after a soft-reset but prevents me to reconnect to the network without resetting.
3.) Ive been talking to the support here at univ. but they claim it is the phone since no one else (10 000 student and employees) has a problem such as I
4.) Same problem with a.) original rom b.) Duttys V3 c.) Duttys v4.
5.) I have tried altering : 3g, active sync, hspda, bluetooth, work/internet, power settings..
In some threads I read that other people have similar problems but in those threads, the problem never seem to have been resolved and the threads seem to be "washed away" over time (people not caring / giving up?..)
I would appreciate your help or even thoughts

bump! Come on now... someone has an answer.

Does it happen when you delete the offending connection and re-setting it up again?
I had the same problem before with a wifi connection on one of my local coffee shops. It'll connect for a few minutes, will say its connected and a few mins later it'll disconnect. After i deleted the connection under my "Wifi settings" and going through the setup, it works like a charm.

the same happends to me at home with my Buffalo WRZ2-G300N, and at many hotspots... i can't find any solution.

If by, deleting the connection, you mean deleting the settings for the offending connection, then unfortunately yes, I have tried that.
Thank you for the hint though!

Ok - I'm experiencing the exact same problem. I can connect fine to my home router - using a WEP key, however, when I connect to my university network via wifi - it connects (after a soft reset) works for a short amount of time and then stops. Only a soft-reset works.
At uni i have downloaded the SecureW2 SecureW2 Open Source EAP-TTLS client for Windows mobile as this is what my uni network requires - are you using something like this ?
As a first step, I am going to use my network sniffer to check the traffic and see whether the connection is dying over the air.
I think we might need to pool all our info on this one - as it's a really annoying problem that must be happening to alot of people.

It is great (sort of ) to see more people with the same problem. Which radio are you on? I have never changed mine, which is 1.27.12.32.

I'm on Radio version 1.27.12.29... I'm going to run some tests at uni tommorow to see what I can come up with.

these are my versions:
CE OS 5.2.1620 (build 18125.0.4.2)
ROM: 1.56.405.5
ROM Date: 8/28/07
Radio: 1.27.12.11
Protocol Version: 22.45.88.07H

All,
I can confirm that I am having the same issues with the German HTC stock ROM.
This device has so many bugs that it is hard to believe.
Regards
GZ

Spent some time looking at the problem yesterday - can someone please try out the following;
Set Kaiser/TyTnII so that it stays on all the time (no sleep or power options set), reset the device and let it connect to the AP - leave it 'connected' for approximimately 10 minutes, open IE and see whether you can browse internet - and if you can - for exactly how long before the session hangs?
Do the exact same thing as above (soft-reset) only start IE just after the device connects to the AP and time exactly how long before it hangs.
With both these tests its very important that the machine does not go to sleep or standby etc...
I've dragged out my old Hermes which I am taking in to uni to test with on Monday along with my TyTnII.
Final question, can anyone who has this issue please post;
Device Name (I presume a TyTnII)
Radio Version
OS Build
Access Point Brand/Model
Exact Security used to connect with (WEP/WPA etc...)

problems with TD 2, pls help

hello,
I have just purchased the new TD 2, it is the first phone of this kind that I use (up till now I have only used Nokia Business phones)
Although I considered myself a person that knows his way around how to use a mobile phone, I was surprised to actually be forced to read the manual for the HTC TD2 - unfortunately the information in the manual is general and did not help me at all...
ok so here are the problems I hit:
1. For internet access I have activated "Vodafone Live!" packet with my network (Vodafone) - (internet works fine with no probs)
However, whenever I am near a Wi-Fi zone I would like to use that Wi-Fi signal to connect to the internet and NOT my "Vodafone Live!" setting.
I could find NO way to select how to use Wi-Fi and not the other preset network. (As far as I can see the phone still uses Vodafone Live! and not the Wi-Fi, although I previously manually connected to the Wi-Fi and I tested on my other phone that it is working...)
2. With my other business phone (nokia) whenever I stop using the internet page the phone disconnects (the 2 arrows disappear) but with TD2 I have the impression that even when I exit from Opera or IE the phone still remains connected somehow to the internet - how can I make it disconnect and not use the battery for no reason ?
The only way I found to manually disconnect it is going to START / Settings / Communications / the Push Data Connection button to OFF.
Is there any automatic way to do that whenever I quit the browser?
Thank you in advance for u`r help

The Touch Diamond 2 will use an active WIFI connection over your Vodafone Live! connection. If you are wanting to connect to a Public WIFI zone, then simply select the WIFI connection that you want from you list on the "Connect to Wi-Fi network" screen.

If this really bothers you there are applications dotted around here on XDA devs that will automaticaly disconnect your internet connection after a preset amount of time. That said though, just because the TD2 has a connection to the internet, does not mean that it is transmitting any data and does not use up any of your internet allowance and also it will not drain your battery that much.

Thank you very much for the explanations and u`r time!
Regarding the first problem above that is good news, although I don’t like it that I don’t have full control over it.
for example I’m going abroad next week for 10 days and I rly don’t want to use the Vodafone live! option as it will cost as hell
an option where I could be prompted and asked if I want it enabled or not - would have been great...
guess ill just delete it from the connections tab and reinstall it when I get back in my country - seems to be the only safe option.
One more thing,
Whenever I try to access a video-clip over the internet (using the IE not the Opera) the phone automatically directs to the program STREAMING VIDEOS program)
And here the clip ONLY works if I select to connect over “THE INTERNET” – why ??
For example if I go to Streaming Videos / Networks, I can find the following:
Vodafone Live!
Vodafone MMS
Mobile internet
My Work Network
My ISP
Work
Secure Wap Network
The Wap Network
The internet
What the heck are all those ??? I only know of “Vodafone Live!” - and the straming video does not work when I select it … it only works when I select THE internet (like I said above)

Ah, if you are going abroad or just anywhere that you don't want to use Vodafone Live!, there is a little application called "NoData" which allows you to toggle your data connections on/off.
Will edit this post once I find where it is again.

As for streaming videos, I've never used it so can't say.

Indeed, NoData is a handy tool.
What you can also use is the following one found on XDA-devs:
http://forum.xda-developers.com/showthread.php?t=503131
It will automatically turn off your data connection when you're not on your standard network.
It isn't perfect, but it works well and the developer is really listening to all suggestions and very active.

you guys are a pice of heaven
thank you again for all u`r help
question, this program NoData, also stops Wi-Fi data transfers or just network ?
thank you

NoData will only stop phone network connections. You will be able to use wifi as normal.

wifi sleep policy not work correctly?

My wifi seems to disconnect from my wifi when the screen turns off, despite me having changed my settings to never sleep. When I look at the wifi settings it says "Unsuccessful Connection". I didn't have this problem with my MT3G.
Anyone having similiar issues or a fix?

wifi Reconnection issues
I'm having the same problems with mine.
It initially connects to wifi fine but when the screen goes off it sometimes drops the connection and will not reconnect without a reboot.
I have tried setting it to keep the wifi when sleeping but it makes no difference.
I found a few similar reports elsewhere and followed most of the suggestions, like changing routers, changing wifi channels, setting an IP address instead of DHCP etc. Nothing seems to make any difference so far.

Mine never seems to reconnect after waking up, but I just go into the Wireless settings/Wifi settings window (where it lists all the Wifi networks in the area) and press on the network name and it brings up a dialog allowing me to connect again. I press the Connect button and it instantly reconnects. No reboot required...

Try increase your router's "Group Key Update Interval". I had the same problem with my D-Link DIR-655. I changed mine to 10 hours and it's working fine for me now.

i have the issus that my wifi is "connected" i mean i see the logo at the top bar but after a few minutes i don't get any update from the internet like gmail oder twitter when is wake up the device from sleep i get them back again
maybe it something with the Group Key Intervall but i can't switch it on my speedport w700v router

I just tried switching mine, highest it can go is 7200 seconds, so I bumped it to two hours instead of one. linksys
my wifi reconnects when I wake the screen almost 100% but it's not reliable.
I have to go to wifi list and reconnect. Sometimes I disable wifi and then re enable, conects no problem. Irritating

i heared that switching the encryption from wpa/wpa2 to only wpa2 will solve this issues, will try it when i am at home

...seems like almost everybody got this problem.

for example with my Hero i don't had this problems so it's something with the W-Lan card of the Nexus

Got this problem too but will try the suggested work arounds when I get home tonight

found out that my encryption is wpa2 not wpa/wpa2 ... damn so thats not the reason
and my router cant configure the group key intervall

I don't have this issue, running CM5.0.3.1, mine is set to Never Sleep and it does not. My connection does not time out either. I connect to two Trendnet TEW-637AP's at home, in mixed b/g/n mode with WPA2-PSK mode security.

Could it be, that this prob exists just for nonrooted phones?!

i've got mcr 1.6 which is rooted and don't work
i think it's a problem with the wifi card and the wifi router
rooting just means that you get read/write access to all folders
doesn't change anything on your wifi connection

Not exactly, it means also modified system files, which could include those that interface with the wifi chip and those that control the sleep state of the device.
Also, Cyanogen (and most other custom roms now) are running on a different (newer) kernel.

yes i know
but mcr is although running on different kernel and it's not working there
i don't think its an issue bei the stock rom and mcr
maybe here is someone with CM where the wifi drops?
edit:
okay i tried it with the desire rom version from modaco, the same failures, maybe i try a CM built now, and see if it changes
Code:
[B]Rom [/B] [B]Router / Access Point[/B]
MCR 1.6 | Speedport w700v | not working
Desire MCR | Speedport w700v | not working
CM 5.0.3.1 | Speedport w700v | not working
i think this means it's not a rom issue, its something with the routers and access points in combination of the wifi card from the nexus

That´s strange..perhaps just accidentally, but: yesterday I installed "Task Manager" , which has an auto-kill function.....since then my Wifi reconnects perfectly

maybe because it automatically does anything inside of the 10 minutes which keeps the wifi active?
which one did you install?
there are a lot of them on the market
which developer?
edit:
ah i found a strange issue, today i was at the wifi of my girlfriend, she has the same router BUT i don't have the wifi problems there, with the same model of router thats very strange

i found another work around, i set my twitter client to 5 minutes update intervall, this means every 5 minutes is network traffic and the connection won't drop after my 10 minutes public key intervall change
don't know how much battery is used while setting from 10 to 5 minutes but i think it should be okay

Try a different WiFi channel
I've seen reports of WiFi connection problems being solved by changing channels on the AP. Channel 10 seems to be a consistently reliable choice.

[Q] Wi-Fi Woes

Ok I have a very iritating problem.
My captivate works amazing in all ways... except one. When I'm at home connected to Wifi, within a few mins of me putting the phone down, or even mid use, the wifi will just stop working. The icon still shows it to be connected however no apps are able to actually get internet. A quick pulldown of the quick access menu and tapping wifi off and back on again gets it going great... for another 5 mins. Then the same thing happens.
Its been like this ever since I got the phone, even after flashing different roms. Now i'm running a Linksys Wireless - N router - maybe they're not playing nice?
I dont think its a hardware fault because when I serve wifi, IE the captivate is an infrastructure mode access point for 3g, it stays on consistently and my laptop can tether for 2 hours or more.
Anyone know what might be causing this?
Thanks

When you have wifi on, go to menu settings and 'Wireless and network'. In Wi-Fi settings you can change the Wi-Fi timeout.

Try goin to settings->wireless and networks-> wifi settings (menu key)advanced and set the sleeping policy to never

I've done that...
i *Think* i've fixed it. I was using WPA2 IPK encryption or whatever.. Switched back to the 64 bit crappy WEP. Wifi was on all night and all morning with no cut out.
Might be just another linksys-is-crap situation.

HI, I figured I keep my wifi woes within a singe thread so.
I have an old D Link WBS 2310 router.
I recently got a message from AT&T that I'm near my data limit. This surprised me as my last cycle I barely got near 500mb. Since my bill isn't ready yet, I can't see exactly what it is I'm doing to use so much data.
TO be safe I figured I'd pull out my old router and set it up. After hours of hassle getting it to work on my new computer, I wasn't able to get my Captivate to hook up to it.
My laptop works fine. It gets a fast wifi signal, but my phone just says "Obtaining IP address" for a while and then gives up.
My phone gets wifi at work, at friends', at coffee shops - but not at home.
I've tried this with no encryption, WEP encryption and WPA2 encryption.
Each time my laptop would hook up to the wifi but my phone wouldn't.
I searched some other forums and found similar problems with HTC phones.
Some answers say that D Link sucks. But that answer applies to other brands as well.
Do I need "n" wifi, rather than "g"?
I don't want to buy another router only to find it still doesn't work.
Any help?

part of the IEEE 802.11n standard is backward compatibility with all previous 802.11 standards IIRC, so there should be no need to buy a new n device.
HOWEVER, i am also having issues with my wi-fi and my g capable router. i will meddle around with some phone and router settings to see if i can fix this, this is one area were i can actually be of some use on this forum

Hi. It turned out the wifi was broken on my captivate. I reset it to stock and it's all better. It had been working up to the previous day so I assumed that it was still working. The router goes down intermittently in general, so I've ordered a new one to see what's up.

Hi, I'm back! So after resetting the phone and getting wifi to actually connect (rather than being stuck searching for IP address), I'm now having the exact same problem is the OP. The OP seems to have solved this by switching to WEP. I tried this and it doesn't work. My timeout is set to never. Also, it's the same at home (I replaced my router) as well as at Starbucks and a friends house.
I'm connected, but can't download or sync. It works initially and then stops, and then comes back in briefly and then stops, all the while "connected." Sometimes I can fix it temporarily by turning off wifi and then turning it back on.
SO what's the deal? Is it a hardware problem? Is there some secret magic code?
edit: Just disabled encryption - same problem.
