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.

Wifi no longer working with paul's froyo [FIXED]

anyone else having the problem of wifi no longer connecting after updating TO froyo?
edit:
Okay just had coworker enable his nexus as a hotspot and I connected fine.
Must have something to do with the phone's wifi driver and home router.

Wifi still good for me.

Re: Wifi no longer working with paul's froyo
I see a bunch of people reporting alot of bugs in Froyo, i havent seen any bugs yet. My answer to OP is: No.

i can't get wifi to work on any froyo!
it's just obtaining the ip adress but not connecting

i'm having the same problem on my phone. i flashed the stock rom update-nexusone-EPF21B-signed, the the frf 50 rom and everything was working fine for a few hours then suddenly it stopped working. now when i try to turn on my wifi, it just scans then says it's disconnected then starts scanning again.

everything is working fine but i just can't get any wifi! :'(

Okay, glad I'm not the only one. Wonder how we can go back to older wi-fi drivers.

This, I think there's a lot of operator errors going on that are being blamed on FroYo

Hey if you got any ideas on what I did wrong, I'm all ears. All I know is wifi worked fine before switching to Froyo.
(but the new wi fi drivers didn't work on 2.1 either and i had to go back to the old ones)

Re: Wifi no longer working with paul's froyo
Mine disconnects after a while of not using the phone. Wifi on profile widget stays on. But in wifi settings it shows not in range which shouldn't happen anywheree in my apartment.
Need to turn off and turn onwifi again to reconnect.

if more than one person is having a problem, i'm certain it's not a user error like one person said it could be (quite an asinine comment if you ask me). it's never an operator error when you turn off your wifi and half an hour later you try to turn it on only to discover it won't turn on.....how the hell is that an operator error?

i didn't have any problems whatsoever. check the md5 hash, make sure your download was fine.
make sure you wipe everything, then reinstall. if you have old data cache'd, and then tried to flash the update, that may very well be the problem.

Yeah, having troubles connecting to 802.1x EAP Wireless Networks, PSK works fine for me at home.
Yes, I wiped, checked MD5 etc..
I'm using Pauls Rooted Froyo zip

i made sure to wipe data/cache/dalvik cache/battery and rotation. i do this everytime i switch roms. after 12 hrs of working fine, i just don't understand why it suddenly quit. before i flashed to froyo, i made sure to read up as much as possible to ensure i didn't miss a step. the worst part is, no matter which rom i'm using now, i have no wifi.

one thing i noticed is pre-froyo, when i flashed pershoot's kernels with new WiFi drivers i could not connect at home, but when i used kernels with older drivers, I was fine. That said, maybe it will work with other WiFi access points a la the point made about not working with certain WiFi router types. Will test when I have the opportunity.

Must have something to do with the phone's wifi driver and home router.

I had problems connecting to my router (a Belkin N1). I set a static IP on the Nexus One and then it works perfectly.
I have tried to connect to my work router and it got a DHCP lease fine and worked fine (only at 54Mbps G speeds).
Perhaps this new radio image has N enabled and something is screwing up with the DHCP lease. I will try to replace my home router with another N router and report back.

I had the same problem with a message saying connecting but not picking up the IP address.
I suspect it was a conflict with the Static WiFi app I was using. I've unloaded this and after restarting and re-saving the static ip details it connected up OK.
For now I'll have to switch between static and dhcp manually I guess....

I came from Desire R19. My wifi doesn't connect as well now, i.e. seems to need a stronger signal from the AP. Last week I was getting 2 bars of wifi for the AP in my office, and now I get 1 or none. I'm getting a bar or two less at home too. I'm guessing some kind of difference in the Radio.

WiFi issue I have seems to be AP manufacturer specific
At home
Pre 2.2 I could connect without problem to my Linksys WRT 600N, no problems, DHCP etc.
Post 2.2 I cannot connect, gets to acquiring address and then craps out and re-scans
At work
Cisco wireless kit, (no idea of type of AP) pre 2.2 connected OK, post 2.2 connects OK
WPA2 security on both setups

[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.

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.

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.

Cyanogenmod & other custom Roms usb tethering issues

I'm using my Galaxy S i9000 to tether internet to my desktop. It works fine until the screen turns off. After the screen turns off, the connection becomes laggy, skype etc disconnects constantly, speedtest shows ping of 300-500 to nearest server (10-20 by default). I hope someone could help me out here. What to do, what is the problem, how do I fix this?
This happens on Cyanogenmod, I've tried 7.1 stable, nightly and CM9 ICS builds, also on Onecosmics ICS. Wifi Sleep policy set to always on. Stock ROMs working fine.
Thanks

I never experience this bug on CM7.1. Are you using Juicedefender or that kind of app, maybe they can kill the data connection?

not using anything, all of them were clean and freshly installed ROMs.

Have you tried to set sceen timeout to "off"?
Does it work then?
I didn't experience that bug either tho..

I've tried to set timeout to 30min, and if I not turn it off manually, the connection is working fine for the 30 min, after the screen shuts down, it becomes laggy as hell.
Should I try setting it to off, and if yes, how do I do that?

Also, I'm not sure if it's a tethering issue and not a Wifi one. Can't think of a way to test it without tethering. Any ideas?

Have you tested any tethering apps from market? Like Barnacle Wifi tether.
Have you tested USB tether? There are apps for that on the market also if CM's own usb tethering doesn't work.

Just now I flashed CM7.1 stable just to try out different usb tethering apps. Nothing works, everything is the same. I've tried easytether, quick usb and PdaNet. PdaNet came with some windows drivers for the phone which were different from what I've had before. I've tried to install those, no change. I should probably test wifi tethering just to see if it works.

I tested to wifi tether my 3g connection, everything works fine screen lock on and off. Tried to usb tether my home wifi connection to another computer, had the same problem. Any more suggestions? Thanks in advance
