Wifi bugging out

Hello, recently my wifi has been acting up. Sometimes it will say it is connected to my wifi network but no web pages or anything work. It happens after I leave my phone in standby for a while, and it will usually start working after restarting my wifi. After I restart wifi so many times it will disconnect even when it's not in standby (and more often) and then eventually the wifi switch on my home screen stops working.
I'm running Android 2.2 Froyo Cyanogen Mod 6 RC2 FRF84B using the jdlfg 2.6.32.9 overclock 300 mhz+1200 MHz kernal.

ok sounds like there could be two reason for this, either the rom or your router. First make sure you have the latest radio for your phone. If possible try a different rom or a nanadroid restore. on to the router, do you have other wireless devices in your home? Are you experiencing this issue on any other device? You may want to try connecting your phone to a different wifi connection just for testing. connect to any available open connection and test to see if the phone does the same thing on a different wifi connection. Now if it does then you know it's most likely an issue with your phone. if that's the case you would want to focus on the rom and or your radio.
If you do not have the same issue after connecting to a different wifi connection then it's not the phone but your home network. You will need to trouble shoot your router, good luck

I'm fairly sure it isn't my rom, although I did only notice it when I started wifi tethering on 2.2 (I never tried it on Eclair though, I only decided to root when I heard Froyo had been leaked). I'm on Cyanogen (I used to be on the stock froyo) and I still get the same problem, I also updated my baseband and I still get the same problem. As for my router I doubt it, my laptop never seems to disconnect along with my wii and any xbox my friends bring over. My sister's Droid also doesn't seem (emphasis on seem, she's not a power user or anything of the sort and I'm not even sure if she has her phone on wifi half of the time, and neither is she, the last time I checked it was connected though) have any problems (she just has a stock Droid, nothing special).
I've tried a newer version of Froyo (I don't have the latest build though atm, but that's because Cyanogen doesn't support it yet).
Does the Droid connect to wifi in any special way that other devices don't? If so then my router might still be a suspect, as I admit the firmware it's running on is glitchy (it actually worked better before I updated it (I was trying to get some remote router switch on my PC to work with it)).
Edit: I discovered recently that no other wifi networks come up when wifi bugs out, although it seems to only happen sometimes.

Fixed the problem, apparently it's caused by a glitch in the settings, when you change the wifi sleep mode settings so that it doesn't sleep after idling for so long the phone assumes it's been changed but it doesn't actually change. Downloading WifiPowerSavingOff fixed it.

[Q] Samsung Galaxy S Wi-Fi problem

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.

[Q] WiFi issue after flashing Decad3nce's 1.1 r1 ROM

Hi all, newbie poster, but been on the forums for about 2 weeks. Thanks for all who have provided such great methods to unlock the full potential of the NC!
I flashed to Decad3nce's 1.1 ROM yesterday from my Autonootered 1.01 setup, and was able to get most issues worked out, but the one thing left that's bugging me is the WiFi. When I initially boot up, it seems the device recognizes my WiFi network, and connects. However, after I resume the NC from sleep, it doesn't reconnect to my access point. In fact, the only way I've been able to get the connection back it to use the stock browser, at which point I'm asked which network to connect to. It says my network is "remembered", but it won't connect automatically, I need to manually connect every time.
Any ideas on why this is happening, and how I can get the NC to automatically connect to my network after resuming from sleep?
Thank you!

Hi there. Wass havingg the same issue you had. Take a look at the instructions for enabling adhoc wifi on Nookdevs.com Wether you want to enable adhoc or not that's up to you. But i followed the directions for Settings Profile Pro from there. Now everytime i turn off my screen and turn it back in. My nook connects right away to my wifi network.
Edit: Mine connects fine. But with my wifes nook. If she is coming off a reboot. She would have to goto settings and connect initially. But after that. Everytime she turns off her screen and turns it back on it reconnects right away.
Good luck.

I had that problem with 1.01. It occured after I ran the script for swapping the adhoc and infrastructure supplicants without disabling wifi first. The only thing that fixed it for me was a full reset from 1.0.0. Router was a verizon fios router/modem.

I had this problem before and can't test if it still happens but for me it only happens with one wireless network and all the others are fine. Is that the way yours behaves? Since it worked fine with others I didn't really worry about it
You said you can only get it to work by opening the browser - does that mean it doesn't work if you toggle wifi off and on? That was usually how I got it to connect to that one network

Same issue. After sleeping it sees my AP but doesn't connect. Turning wifi off and on recovers it.

Well, it looks like no immediate solution to this other than starting from a factory reset. I restored my backup ROM from CWM that I saved prior to flashing to 1.1.0, and WiFi is working fine again, so I'll stay here on 1.0.1 until I hear of a solution. Plus, XDA app works as expected in 1.0.1 as well. Thanks for any additional help!

I'm having the same issue as others.
Decad3nce wanted some logs so I pasted them into PasteBin:
dmesg - pastebin.com/wsajYF77
logcat - pastebin.com/gPasCEtZ

Thanks for this post. This seems to have solved the problem for me.
Edit: Actually this didn't work I just didn't let it sleep long enough. Once it sleeps for several minutes WiFi requires a reset to reconnect.

Dmesg shows nothing wrong with tiwlan driver.
Logcat shows that the "nookwifimanager" just fails at reconnecting to preconfigured networks
Code:
D/NookWifiManager( 1188): Cannot connect to pre-configured networks
What kind of security do you have on your router? (might be wep bug)
Other than that, you can try using the patched wpa for ad-hoc

I was having an issue where it it would connect to Wi-Fi for a minute and then disconnect. I could turn off wi-fi and repeat the process. I restored to my last CW backup then I used the 1.1_r2 and everything worked perfectly. I'd rollback to the backup you did (if you followed Deced3nce's steps) then use the r2 update. It's made all the difference for me.

I flashed r2 and I'm having the same issue...I have to turn off/on wifi after it goes to sleep in order for it to connect

Did you flash it over top of r1? Or did you start with 1.0.1? And were you using any special kernels prior to the flash?

similar issue - wifi only works after a reboot. after sleep it can see but cannot connect to either adhoc or infrastructure networks. no fix other than to reboot. which is a huge PitA

I actually flashed it over rooted 1.0.0. And I was running the 900 mhz kernel

[Q] CM7 nightly Wifi issue. Unable to connect.

I am having a wifi connection issue with CM7 nightly build 14&15. When i try to connect to my wifi it allows me to type in my passcode then proceeds to attempt the connection. It appears to be caught in a loop or something. Under wifi connection it shows scanning, connecting, then disconnected then it repeats. Wifi works fine under stock unrooted, rooted and nookie froyo SD. Does anyone else have this issue? I cannot post to android development yet. Thanks in advance.

I have a clean flashed 15 right now, and wifi is working stellar. Did you by chance not format cache/data, and still have a bunch of saved hotspots in wireless? I know a fix earlier was to "forget" all the saved wifi hotspots, and resave them.

Same problem I have been experiencing among others. It seems like if your router is using WPA you will have problems connecting. Switching to a different security encryption or wiping all remembered access points seem to be the only solution that I know of.

Yes, I formated system, data and cache when installing. CM7 works great on my Evo 4g, strange. I tried forgetting the hotspot and received the same error. Will try an unencrypted hotspot and will report back. Don't really understand why I am having this issues and others aren't. Thanks for the replies.

I've seen like 6 other people with this problem its not just you.

I'm experiencing the same problem of Wifi flashing on and off when I try to connect to a WPA encrypted router. Will try to Forget saved networks and see if that solves the problem. I'm running phiremod's version of CM7.

Mallinj. Same issue here with phiremod. Forgetting did not work for me. Let me know what happens for you. Thanks.

That wifi file is named nookie froyo. This definitely works for cm7?
Usually what I have to do is some voodoo with toggling airplane on, then let wifi loop for about five minutes before it finally connects.

Been having this issue as well, what I have been doing when it has been switching on/off in the Wifi Settings is hitting Menu > Advanced settings and waiting a few seconds and it usually connects just fine.

Yeah it works. It takes the working wifi file from nookie froyo and pushes it to your CM7 file.

Has anyone submitted a bug report with cyanogen yet?

I had this same problem yesterday morning. What I had to do was forget my network's settings, turn off wifi, then go turn off my router, turn the Nook's wifi back on, let it sit for a few seconds, turn my router back on, then try to connect. Strange as it sounds, this actually worked.

Time pilot aka, Thanks for the tip! Will try it later today.

Finally
I was able to solve my connection loop issues. I tested WPA and WEP on my D-Link Wireless N router DIR-615 with no success. Tried toggling on and off with airplane mode. Tried forgetting my router, turning things on and off at different sequences and intervals.
Then I set my router to B&G only. Basically turning wireless N off and it worked like a charm. I am able to connect using any encryption method. So from my experimenting it was the wireless N protocol that was the issue.
For people out there with issues and want to keep their wireless router encrypted try turning wireless N off. Worked for me.
Thanks everyone for their input.

[Q] Wifi stockrom ICS

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.
