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.
I have a Samsung Galaxy S Vibrant device and a strange Wi-Fi connection problem.
It seems that the WiFi conneciton is being lost intermitently with no apparent reason. I ping the device, most of the time there is a 'Request timed out' and only sometimes a 'Reply from <address>'.
On the device side the connection behaves erratically as well, sometimes there is connection but most of the times there isn't. The strange thing is that under device's Settings->Wireless and network->wi-Fi settings the connection's status is "Connected" all of the time, signal strength is excellent, link speed is 54Mbps.
I had this issue on a native 2.1 Samsung Galaxy S Vibrant install, then decided to flash a custom 2.2 ROM hoping to end the mistery. The new custom ROM is an Axura21VE.zip and the WiFi connection problem is exaclty the same as before.
Does anyone have the same WIFi issue as I have? And yes, I did a search before posting this. In fact, I searched for several weeks and saw many SGS Wi-Fi problems being reported but either they are different or they are similar to mine with no solution. Since I need a stable Internet connection on the device for app development, next logical step would be looking at reverse USB tethering. Yet decided to post here before giving up on Wi-Fi.
For the record, the Wi-Fi acces point is under my control, i have a ASUS P5B-MX/WiFi i946GZ motherboard, windows XP sp3. I tried, I think,
every possible combination of Wi-Fi settings available. The only client device I have at home is SGS. At the office network, SGS is having the same
Wi-Fi issues, while a HTC Desire and many laptops don't.
here is what I just found out: if I do a constant ping form the device to google.com for example, then the conenciton is maintained all right. So, should I constantly ping something to maintain a decent connection? Is there a setting or something in Android OS I am missing?
I had this exact problem - changed my router and it works perfect now. Really weird and not an ideal solution but worked for me so far (touch wood!). Try playing about with your wifi config maybe, change encryption, channel etc. Good luck.
Hi, I'm having the same problem on my Galaxy S i9000 on Darkyy's v7.8. I never used to have this problem until I flashed the second to last release. The device says I'm connected to the network but I can't get any internet access. I tried reflashing my official firmware DXJPA, but I still no joy. I'm not really sure what to do.
YES... i have been searching for days. I feel I may have a similar issue. im connected, speed good, IP there.. no data, browser just hangs. seems to happen less in stock. (Rogers captivate, P10.1) also WiFi manager reads my WiFi channel off by 2!! so im set to use ch 9 on the router and WiFi manager on the captivate says its broadcasting on ch 7?? any ideas? ping to infinity??
side note: this happens on all routers and all roms. other galaxys on my network read proper ch... GF's Iphone see the right channel?? HELP..
I'm also having these problems, reposting my reply from another forum:
Just wanted to chime in that I am also having these problems with my samsung vibrant. Seems to only happen from my work router but happens very consistently. Wifi will work immediately after setting it up but after a short time period will stop working completely. It will say it is still on wifi but will in fact have no access to the local network or the internet. Stopping/restarting the wifi connection doesn't fix it. The router has to be manually 'forgotten' and then re-added for it to begin working again. (Update: sometimes this does not work either, in fact).
This is with a 2wire modem (standard issue by at&t) using WEP security in 802.11b/g mode.
Some people recommended switching from 201.11b/g to pure 201.11g. I tried this with no luck. It was also recommended to try to app 'wifi fixer'. This also did nothing to solve the problem. Given that it is my work router, I don't want to go changing the encryption and other crazy things as I'm not the only person using this router and it would break the connection for others.
MRSizzle in another thread (which xda isn't allowing my to link to) seemed to accurately describe the problem as such:
"It appears to be a driver issue with the Samsung base OS drivers in the phone. Possibly sleep policy is not operating correctly and the wifi radio is being disabled by the hardware and is not being controlled correctly by the software so the WiFI icon still appeers to indicate the phone is connected. Also the wifi signal is not being correctly reported. the signal appears to be attenuated more than it really is."
This description would line up with the OP's reports that repeated pinging will keep the connection alive.

ASK DARKY its his rom and will know more .

Anyone figure this out? I'm trying to use the Web Desktop app but can't because I can't even establish a connection with my phone!
Hi friends,
I have similar problem, but at first I easilly connected to Internet, but now I can connect to my WI-FI but no internet connection. I am not sure but maybe this has occur after updating to Android 2.2.
Any suggestion?
Thanks in advance.
explanation and apology
I was wrong in my assumption that it's an Android device problem. The problem was in the Asus motherboards embedded Wi-Fi access point. I bought a separate Wi-Fi router and now everything works like a charm.
Since a few days I'm running the ICS stockrom on an unrooted Note. Before on the GB I was have not the best reception with Wifi, but it was working. Now, with ICS, my Wifi is connecting/disconnecting/connecting/and so on within a matter of seconds. I'm experiencing this on multiple Wifi networks. Therefore I would say it does not concern the settings of my Wifi network, also I'm practically sitting on the router (channel, reception can't be issue).
I've installed ICS via Kies and have done an additional factory reset today.
Does anybody know what could be the cause of this? And, more important, how to solve it?

Others have had similar issues - try reflashing the same modem from here:
http://forum.xda-developers.com/showthread.php?t=1645202
I found that wi-fi and data both worked better after flashing the modem a second time.
Thank you very much it seems to be working!!
I had to look to find out how to get the phone in download mode, but got it.
Sad to say I did an unneeded factory reset this morning, but yeah it is working now!
I've been also noticing momentary WiFi disconnections ever since I upgraded to ICS.
I'm using MyPhoneExplorer to transfer files wirelessly to the device (not via USB), and ever since ICS it has became an unreliable way to transfer files. If I transfer a big file most chances are that the WiFi connection will drop during the transfer, causing it to fail.
The connection is restored immediately but then I have to restart the transfer process as it halts when the connection fails.
I have excellent signal level (physically located close to the Access Point), I tried flashing the latest modem firmware (XXLR1) - twice, I've set "2.4GHz only" in the WiFi advanced settings, all to no avail: I still get these connection drops.
The same setup (phone, access point, etc) has all been working well in the past with GB. Now with stock ICS it performs poorly.
Has anybody got any information about this problem? Been experiencing similar problems?
Thanks!
I've been getting this issue too but it seems to only be with our virgin router, all other devices connected to it are fine although the signal is a bit crap on them to its at least stable
I tried the modem flash etc but no improvement, I'm pretty sure its the ****e virgin router

At my side it seems to be working better now, steps I've taken (in this order):
1. Flashing new modem
2. Enter fixed IP address for my home Wifi
3. At Settings->Wifi->Advanced->Leave Wifi on when enabled
Especially the last seems to have done me good. I have it working in combination with BatteryFu so it does not consume my complete battery.

Well, the AP that I had problems with is a relatively recent D-Link 802.11n router. Nevertheless, I tried connecting with an old Cisco 802.11g router, and lo and behold - connection is now stable.
So, looks like there is indeed some interoperability problems but I won't dismiss this as a "****e <X-company> router" - as the same router is working well with other clients, and moreover, was working well with this phone when it was running an older GB firmware.
My conclusion is that apparently somebody at Samsung / Google has broken the Wi-Fi drivers, interoperability-wise.

You probably mean leav wifi on when screen is off? My phone is already set this way... Anyhow, thanks, but it looks like this is a problem with a specific router as I wrote in the first part of this message.
I have problem with WiFi on my new RAZR i.
It is working fine for one or two days. After that I'm getting strange behavior.
When I turn on the WiFi, phone connects to WiFi network but after I while WiFi connection is lost and after that it is unable to find any network.
Turning airplane mode on and off sometimes helps. Reboot of the phone (shutdown and power on) always helps.
What can it be? Hardware? Application? Bug in 4.1.2?
Hi.
Is this on just one wifi device (home?) or you see this behavior everytime (mean everywhere) you use wifi? There is sometimes some strange uncompatibity issue between devices. I have HUGE problems with Belkin and TP link, while Airlive (Ovislink) products work stable with my Razr i.
I see that every time (mean everywhere) when I use WiFi. I have removed WiFi manager and Skype and now it is working fine. I'll test it a little bit longer to be 100% sure.
After that I will install WiFi manager and Skype once more to pinpoint the problem.
Have you gone into your WiFi and gone into advanced and unchecked avoid poor connections? That was causing me a major problem because my phone almost had a choice in whether to connect.
Sent from my rooted XT890 with unlocked bootloader using xda premium :3
So I have a rather odd problem, I installed Nightmare ROM (4.3), and it seems to work great, with the exception that if I connect to wifi, all my other devices lose the wifi signal.
As soon as I turn off the wifi on my note, my laptop and desktop connect fine to the router.
Any ideas / suggestions?
