When I turn on my phone at work, the wireless connection (open unsecured) connects and works for a few minutes. After some time, it disconnects and without rebooting my phone, I cannot establish a wlan connection.
This is oly the case at work. At home it works flawlessly, but it is another network kind.
Anyone found a solution to this problem? I saw a lot of threads about this but no good answers.
I am using duttys v3.
Not sure. Perhaps there is some sort of time out on your work network for inactive devices, or dhcp ip releases or something weird and "networky" like that?
Or perhaps your phone is going into a power save mode if you are not using it?
Just general ideas, I don't have this particular problem
I dont think many people have this issue! you must not have a setting correct, try downloading KaiserTweak and adjusting the timeout and also take a look at the routers settings I find it strange that a business would have an open network for security issues

I work at the university, and the network is unsecure. You have to enter login and pass at a webpage to gain access.
I cannot reconnect at all once ive been disconnected. So it should have anything to do with kaisertweak or timeouts.
I have tried every setting and combination. I have tried to select work/internet settings. Ive tried to tell the phone its a hidden network / not hidden network. I have tried to use power save / performance mode. Ive tried to turn off 3g, bluetooth, phone (everything basically).
When I tap connect, it says connecting and then it immediately goes to "active" and tries to connect to another network (which I dont have access to).

I have worked out the problem.. first if its a WPA enterprise connection, make sure its set to WORK and not INTERNET setting. it will work. my only works with schaps versions not duttys
on my old pda (Acer N50 premium) I had the same problem with my unis network... it would only work (if at all) for a few minutes then nada... but at home it was absolutely fine, quick stayed on and totally responsive... I wonder if it has something to do with the rubbish way unis run their IT...?

Many do not have this issue.
According to what's being said here by the indiviuals with issues, you're having problems connecting to a certain network...not all networks.
If it were all networks; your device, settings, equipment or rom would be the common denomenator. Since it's one network, it's that network.
Just because a network is or appears to be available, that doesn't mean that you can connect to it.

no, it could be the phone software. Lets says that a string is added to the registry if the network you are connected to disconnects you; a string that makes the phone cancel connections to the network. And lets assume that the network disconnected you because there is a hidden firewall in the phone software that blocks ping requests, thus making the network believe that the connection is lost and thus disconnecting you. Then we have a moment 22, which is basically something wrong with the phone.
As some readers already pointed out in this "wasted thread", when changing the rom (in one case) or when changing settings from "internet" to "work" (in the second case) there is a great possibility that this problem in fact has to do with phone software and not network.
In my case, it just happens to be neither of the mentioned solutions or any solution that I have found in other threads.
One thing you may want to check is that your wifi is set to max performance. The issue may also be that there is a DNS cache issue, in most cases it can be resolved by manually reconfiguring the connection.
I have been successful in configuring my phone's WLAN to connect to everything from open APS's, WEP, WPA, RADIUS and AP's with proxy redirects, so I can tell you that as with most cases, it's human error.
I have tried max performance.
How do I resolve a dns cache issue? Manually reconfiguring the network did not help (only thing that helps is a reboot).

Hello
since installing 3.4 I have had issues with this rom however none so serious I jumped ship however I have problems with conecting to my home wifi which is causing pain...
I have set up wifi on my note as dhcp and my netgear router is also set to give ip address via dhcp however the note will only connect sometimes otherwise the message 'obtaing ip address' is shown then the connection drops to remembered and then Im back on 3G. I have tried various fixes including re-flashing the rom providing a static ip address. I have this issue with any dhcp network the note just will not connect all the time...

It happen even on stock to me mate.What I do is turn off wifi,go to browser and navigate to any site(yeah with wifi turned off still and data network off),when it gives you error turn on wifi and refresh the page.
I know its irritating but I have no solution and it works for me
still trying to find a solution to this. setting wifi sleep policy to Never seems to help I also deleted the dhcp_list file which forces the note to reconnect from scratch each time it connects to a known network rather than selecting it from the list. still not a full fix. seems to be a samsung thing rather than rom based. do the modem downloads available control the wifi functions or are they just for radio 3g etc as I will try a different modem to see if that helps.....

I just got an Sony Xperia T,
now I was trying to connect is to my router with the 5ghz-band, but the Xperia T can't find the network,
so then manually added the network, inserterd password, but then it says that the network isn't within reach,
but i'm sitting next to the router, the 2.4ghz-band works fine, and sony confirms that the phone should work with
the 5ghz-band in the white paper of the phone. Does anyone know how to solve this problem?
BTW, my router is a Netgear WNDR3700 Dual Band.

On your router have you set it to dual band as a lot of the time they have it defaulted to 2.4 b/g so you'd need to change it to auto or whatever option allows all. On my Linksys it says 2.4 and 5 as an option in the dropdown. That would be the only reason I can think of. Have you tried with any other device to connect to your 5ghz network?
Likely a router compatibility issue. I can connect to a Linksys e4200 on 5ghz with no problems
Sent from my Xperia T
My Xperia T refuses to connect to my WiFi AP. It's only 2.4GHz, but according to the logs on the AP, it isn't even trying. On the phone side I very briefly see "Connecting" or similar on the AP list, then it reverts to Saved.
Log on phone is filled with entries like this:
Code:
I/wpa_supplicant( 565): wlan0: Trying to associate with 00:0c:42:XX:XX:XX (SSID='LFWnet' freq=2412 MHz)
I/wpa_supplicant( 565): wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:0c:42:XX:XX:XX status_code=1

This happened on the stock Vodafone ROM, and still occurs on the Generic UK posted in General. I have tried WPA and WPA2, TKIP and AES, different channels, disabling N etc etc, still the same
Tried soft/hard reboots, wipes etc, nothing. It has connected to other public and protected AP's fine.
Am gutted as changing my AP to work around this problem is a no-go. Not had any problems with various other laptops and phones, including other SE/Xperia devices.

I'm on generic UK rom and using a BT Home Hub without any problems. I've also got my old dLink wireless n router I use as a print server and it works fine with that too. My brother has a Sky router (Netgear I think) and that works fine.
I think you must be unlucky.
---------- Post added at 07:11 AM ---------- Previous post was at 07:07 AM ----------
Is your SSID published? Have you tried turning off all security on the router to see if you can connect then? (obviously I'm not suggesting you leave it unsecured but it is something to try.)
Also, posting your router details may give you an idea if others have been successful with that router before you splash any cash on a new one.
Hi, my Xperia T also is not able to connect with my e4200 5 GHz WiFi. My Laptop and a Samsung Phone works without any problems... I read (sorry I don´t remember the forum link) Sony did not enable the 5 GHz frequency because of driver issues. But if it works on some phones, maybe it´s a provider specific issue like the permanent bootloader lock?
Might be worth updating the firmware of your router?

I think I found the problem, the 5ghz band of my router doesn't have much range appearently, when i'm trying to find the 5ghz band outside of my house, i can't find it, I can only find it when i'm in my room, that's where the router stands, but the 2.4 ghz band has a much better range, I can connect to is almost 20-30 meters outside of my house. I'm wondering when Netgear is coming out with an update for my router, hopefully that will solve the problem, or maybe it will be solved when the Xperia T gets an update to Jelly Bean.

Hi there,
I've just bought the Xperia T and I'm pretty disappointed I can't use my home wifi.
I'm having exactly the same problem - I can see my connection and connect (sometimes) but it is a very poor connection, then after a minute or says "Not in range". If I go outside (which is actually closer to where the modem is) I can get data at an acceptable speed.
Sorry I'm such a noob but can you explain to me where the limitation lies and how I might fix it. Every other device used in the house works - even an old iphone 3gs - I'm surprised Sony's newest phone hasn't implemented technology that must have been in use for years.
Or if it is the modem - any ideas on how to change it.
Sorry - can't give you details - the modem is locked in the landlords garage - so I can't see what make it is.
Thanks for helping a noob.
I have faced the same problem with my TX when connecting to my AP.
I think there is WIFI problem in receiving the WIFI signal of security mode WPA2/WPA.
You can change the WIFI security mode to WEP or No security.
My device can connect the WEP mode WIFI.
Hope you can solve the problem!

Hmmm, that's strange - my modem is set to WEP and it's not really a connection problem but a signal strength problem. But like I said - no other device has this issue. It is hard to test - right now I'm accessing this from a cloud connection which is average compared to another I used this morning, though much better than at home. But I don't know how close I am to the transmitter right now.
Hello again,
I'm still trying to get to the bottom of this:
So my Xperia T can connect and use the wifi in my house fine IF I am within 2-3 metres of my router, which has the following settings -
O2 Wireless Box, model - TG585v7
Software release - 8.2.7.7
Boot loader 1.0.0
Interface Type: 802.11b/g
Band: 2.4G Hz (This unfortunately cannot be changed)
It is currently set to WEP security but when I changed to WPA-2 there was still no change - could only connect when a couple of metres away.
Also even when holding my phone 10cm away from the router I still only get a "Good" connection. So I started to think it must be my phone that is faulty - I've been to coffee shops and picked up the free Cloud wifi ok, though one kept dropping in and out. And I have been into mobile phone shops testing their wifi and it connects.
But yesterday I went to Carphone Warehouse and compared to one of their demo Xperia T phones - the demo was connected to their wifi fine yet my phone could not even "see" their connection - I was sure it was my phone.
But now I'm really confused - today I went to a different Carphone warehouse - there was no demo phone but I picked up their signal and the quality was "Excellent" - something I'd never seen before.
My phone is locked to T-Mobile - can a carrier locked phone somehow restrict access to certain routers?? Seems very weird to me, though I am quite a novice at all of this.
Any help would be much appreciated.
Thanks.
locked phone won't block AP access... maybe backup your data and try master reset.. factory reset... don't need erase sd card.

Are you using the T-Mobile WiFi app? If so delete your connection from settings, then set your home WiFi via the T-Mobile app, it may be connecting to the open one not your full one.
If you don't use the app, I would change the channel on the router and try that.

I use Xperia T in Turkey but I bought ıt in Bosnia. I checked my phone's ID and ın myphone has got Vodafone Wi-Fi .. When My phone's Wi-Fi is online then suddenly myphone begin afresh itself. What is the problem please help me ..
I had the same problem then I discovered it happen only in stock firmware or stock based ROM. Try Flashing CM10 or CM10.1. Your problem will likely be solved.
Hi,
I'm trying to connect to a WiFi network that is protected with WPA2 with PEAP / TTLS.
It simply is not working. No problems connecting with my HTC Desire though.
Anybody experiencing the same bug? I already installed the required root certificates, tried various combinations of user account / password. The thing is, that the network is provided by my university (Eduroam if you are familiar with that) and it is very annoying that I have to fall back to HSDPA consuming my data quota.
Cheers,
chross
Normally with eduroam wifi there isn't wpa2 or other key. Just connect your phone to it, open your browser and you will be redirect to the website of your university and then you can log with your id.
Envoyé depuis mon XT890
Yes!! This is the exact same problem I'm having with my university wifi
http://forum.xda-developers.com/showpost.php?p=33962871&postcount=2
I'd configure the settings on my uni wifi choosing PEAP and then MSCHAPV2 and put in my log in username and password according to the instruction and as soon as press connect or save it looses the signal immediately to very low and never connects. We also have eduroam as an alternative they tried that and same problem just doesn't want to connect.
It works perfect on my htc one x. I'm beginning to believe the phone has a bug.
It does have a bug. It doesn't connect to 802.11 n!
My problem was solved by reconfiguring my AVW Fritz!Box 7270 to 802.11 b+g only and limit the phones wifi frequency to 2,4ghz only. You can find that in advanced wifi configuration.
I'm lucky i only recognized this bug in my own wifi network and not others i don't have admin rights for...
eduroam works for me with PEAP/TTLS but I guess it's 802.11g
I'm on the 40002 rom, but worked also on the 31006
After receiving the 4.0.4 update yesterday, WiFi now works flawlessly.
Cheers,

Hi there,
I got the same problem with my university network in hamburg. I updated the razor to android 4.0.4 (Stock-Rom: 81.5.40002.XT890.Retail.en.EU), also the phone is rooted but still not working. Our IT advices to use WPA2 Enterprise TTLS/PAP authenthication in combination with a t-com root certificate. Every time i safe these setting the wifi signal drops as told by previous posters and the connection fails. When i enter the settingspage again, all settings are reverted to default. This also happens, while trying to connect to eduroam
any further advices?
Thanks in advance!
I have no problems connecting to eduroam at Braunschweig and other citys. Maybe you can visit the IT Desk at your university?

Yep, me and and a fellow student went there and told them about the problem. But they also gave up, after trying about an hour or so. It seems to be a general problem in the used android build, at least there are a lot of post reporting this at the google code repo -> code.google. com /p/android/issues/detail?id=15631 (sorry for that but I'm to new here to post links). I'll try the provided tips like changing the wpa_suplicant file tomorrow and report the results. Seems to be strange issue, if it works for you (and probably others), because a fellow student got the same Phone and has the same issues
Thought I'd just give an update as I have the same issue
Motorola knows about it, it's been reported to them before and said it'll be fixed with the next update.
Working smooth here with WPA2-Enterprise, PEAP and MSCHAPv2. Using it every day.
But I'm not using TTLS, you might want to disable that if you don't have a valid certificate for your mobile/user.
Also important, fill out the "anonymous user" field with your username. Depending on the RADIUS configuration of your IT this might be required.
[edit]
Just checked my mobile. I don't use a Phase 2 authentication, only EAP = PEAP, no certificates.
Got it working!
After 2 hours of searching the web and playing around, I got it working now, following this guide posted on google code repo:
Razr I (XT890), retail eu, running android 4.0.4 (stock), no root
after endless hours of trying i was able to connect to my university network a couple of minutes ago with the combination of two apps.
1. WiFi Connection Manager
Enter SSID manually
Security "802.1x EAP"
EAP Method "PEAP"
Phase 2 authentication "MSCHAPV2"
Identity "your identity"
Anonymous identity "your identity"
password "your password".
2. WiFi Advanced Configuration Editor
Check Hidden SSID
Key Management: unselect IEEE8021X, select WPA_EAP
AUTH Protocols: select LEAP
Enterprise configuration: make sure Identity and Anonymous Identity are set to your identity, Enter your password
check whether the settings are saved in WIFI Advanced Configuration Editor. If not switch of stock WiFi and repeat step 2 (!!!). Now it should work.
Turn WiFi on and connect to network (Stock WiFi; don't care about settings there, phase 2 authentification is still not saved)
After switching the device off and back on it did still work. Same when leaving and returning to WiFi area.
hopefully it will keep on working. i just tested the browser and play store. didn't discover any problems so far.

Thank you for sharing, this made me so happy!
It's those two apps which made my connection possible.
My eduroam configuration is quite different, but the apps did the trick. I fiddled with advanced wifi config editor alone for hours without any result.
Now I just hammered the config into those two apps and what can I say - proxydroid reported a connection a few seconds later.
I dont't know what Moto's Problem with 802.1X is.
Defy latest stock rom - no connection. With CM -> no problem.
Milestone 2 with stock rom - no connection. With CM -> no Problem.
Rarz I no connection with stock wifi manager . . .
My fellow students with their samsung devices seem so have no problem at all. ^^
(even Win Mobile 6 works, thats a little bit depressing)
btw, speed is fine here. 16Mbit up&down is more than I need on a phone.
Greetings from Kiel.
Hi guys,
My phone: Samsung Galaxy S3, GT-I9305, Android 4.1.2
I changed the ISP (Germany: To Unitymedia) and are now supposed to use a cable modem which as well serves as wifi router. My hardware is TC7200 (Technicolor).
After setting up everything, the wifi connection to Win 7 laptop and Apple iPhone/iPad is working fine (also LAN connection to laptop of course).
The S3 showed a funny behavior: It is possible to establish a wifi connection and it gets IP address assigned. Default gateway, DNS server looks all fine. However, this is only the wifi signal but not an internet connection. It is not possible to reach any website.
The strange thing: If the google site is cached (from a different connection and then switching back to this problematic one) I can run a google search and get results displayed. However, it is not possible to open any websites displayed as results here.
I tried several things based on suggestions in the net, like restarting the s§, using static IP address, changing wifi ports, disabling wifi encryption completely, restart the router, factory reset the modem/router. Finally I performed a factory data reset for the S3 but this as well, like all other things, did not help. The phone was never rooted until before yesterdays factory reset, because I wanted to use Titanium Backup which requires root rights.
Of course, in all other wifi networks so far, this S3 works absolutely fine!
I am not sure if this matters at all, but with the new ISP I got an IPv6 IP address while before I had IPv4.
To be honest, it might simply be a hardware problem which has to be fixed by Firmware upgrade by ISP. This problem is sort of known to them and when I called in they promised a firmware update in November. But anyway, it would be interesting to understand more about it and usually there is a solution for everything Nevertheless, I couldn't find a solution in any forum yet.
Any suggestions / ideas welcome.
Thanks!
EDIT:
Post already moved.
Reads like wrong settings more than hardware .
WiFi is kernel you can flash a kernel .
But i would reboot router and phone then set up wifi with no security first .
