Ok, I have seen this on 2.3.5 builds of CM7, Deck's ROM and OMFGB. What is going on with wifi on 2.3.5? It's causing some kind of wakelock apparently. Look at the right hand side of the battery graph and compare the "awake" to "wifi" time. I had my wifi to sleep when the screen turns off, so it went away when wifi was turned off. But then if I connect to wifi again with the screen off, it causes wakelock. Is this a known issue? I have tried googling and can't find anything about this. Surely I can't be the only one.
On Sense roms I can leave my wifi sleep policy as "never" and it doesn't cause any issues.
I'm using the CM7 nightly build 180 (2.3.5). I'm using Tiamat Kernel SBC. My WIFI sleep policy is set to never. It's been unplugged for about 8 hrs 45 minutes and connected to my WIFI. It's been on standby for the most part and it's at 99%.
WiFi totally unrealiable on the AT&T Atrix 2 (MB865)

I too am seeing all sorts of issues with WiFi on my Atrix2 (MB865) which is also running Android 2.3.5. As a matter of fact, I have TWO of these, because my wife got one also, and it has the same problems. To be specific, both phones will drop 128Kbps streams and fall back to 24Kbps, if the alternate slower speed is offered. This constant dropping of audio stream is the most annoying problem, but the phone also will spontaneously disable WiFi. After manually re-enabling, it can take up to a minute to reconnect to the AP (the happens at home and at work).
When connected, a speed test might show something like ~100Kbps down. But disabling and reconnecting a few times will help get it back to a good ~20Mbps down again. Sometimes when connected ad showing a FULL STRENGTH WiFi status icon, I am still not able to get any data whatsoever, just as if the WiFi is not even enabled. Examining this with WiFi Analyzer shows that it detects no AP's whatsoever, even while the status icon shows a FULL STRENGTH connection. Again, disabling/enabling can correct this issue.
Just to prove it's not my home AP, I have an old HTC Hero running a CM7 nightly build from 9/1/11 kernel 2.6.29-6 (which is also Android 2.3.5).
My old HTC Hero connects quickly/flawlessly and holds a constants steady 128Kbps stream all day without fail.
Why can't these carriers (AT&T in this case) put out a reliable Android build. I can't help it, but my paranoid mind makes me think it could be purposefully done to force customers to use precious bytes form their costly data plans. They certainly would have no incentives to make WiFi work efficiently.
Anybody got an ETA on CM7 for this phone?

I notice sometimes that my wifi will disconnect, and when I go to view the network list my home network will say "disabled" under it. I can connect easily by clicking it again, and it doesn't happen that often, but it can be a real battery killer if I don't catch it due to poor service at my house.
yep! same issue here. Every single version so far including RC1.
Yay. Someone else has the same problem as me!
I don't have this issue, I flash the nightlies (well, nightly). I only have my phone associated with one WiFi spot and that's at my house. I use JuiceDefender so that WiFi is automatically disabled when I leave, and enabled when I'm home (location based).
Bump! I'm still getting this problem with my school's wifi network, and it's a necessity that this works for me becuase I have terrible coverage in my apartment.
I have this issue as well. When the phone sleeps, WiFi will disconnect and the connection will show as "disabled." I, too, am using CM 6.1 and I have the WiFi sleep policy set to "never."
I get this issue a lot at work. I always assumed it did it because I'm usually on the edge of the WiFi network, and so after jumping on-and-off enough, it just disables the network.
EDIT: Here's the word from #CyanogenMod on Freenode:
[11:09] <DrMacinyasha> http://forum.xda-developers.com/showthread.php?t=740773 <--Can anyone/any dev comment on this? WiFi networks get marked as "disabled" sometimes on 6.1RC and Nightlies.
[11:11] <@pb> DrMacinyasha: happens when the phone can't register on the wifi network - for instance, you walk into range just enough for it to try, and then in the middle of it trying to get an IP address, you walk out of range again...
[11:11] <DrMacinyasha> Does it re-enable after a certain period of time?
[11:12] <@pb> DrMacinyasha: generally speaking, no

I'm glad someone actually figured this out. I don't have the problem as much on CM6.1, but it does happen occasionally. I usually just disable and re-enable wifi, but sometimes I have to completely forget the network and re-add it.
Hi all,
I'm wondering what is better option in the Sleep Policy for battery life when you have no access to a WiFi network? Sure, sure, turning off the WiFi will get you better results when you don't have access to WiFi but the location features you get from using WiFi.
At work I have no access to the WiFi network which isn't connected to the net anyways. But it works great for getting precise location information when inside the building.
I tried keeping it on "Never" but wow does that kill my battery.
Does putting it on "Never when plugged in" or "After 15 minutes" keep it from searching for a WiFi signal all the darn time which is what is killing my battery.
From what I have seen since I changed it to "Never when plugged in" half way threw the shift it doesn't seem to draw as much power. But I did check my Google Latitude history and it seems to be pulling my location from WiFi instead of the cell tower. All but a few times did it get the location from WiFi instead of the cell tower. So that has me wondering is it still looking for WiFi or just turning it on when getting a location request.
Any help would be appreciated.
Thanks
I am using a stock HTC Droid Incredible.
I would like to have it where when the screen went off the wifi went off, but that could be a problem if the screen keeps going on and off from texts or whatever else. Would probably use more battery starting wifi over and over again.
HI Guys,
After having moved from my HTC legend to an HTC trophy 7 and getting used to all the interesting little fiddly bits of WP7 I was finally happy (Im mainly talking about the windows live mail contact sync issue).
All contacts finally fixed after a some time sorting them all and adding the phone numbers etc.
Anyway long story short the does not seem to be a way to make the WIFI stay on when the phone sleeps meaning that my preciously short 3g data will be used (Vodafone skimping and giving us only 500mb).
Has any one come up with a way to force the WIFI to stay on ala android sleep policy?
Cheers guys!
Your 3g would only be used if you are constantly downloading emails. Everything is push on WP7 so there wont be apps pulling data other than email. I wouldn't worry about it. WP7 is not android.
If I disable 3G while sleeping on WiFi is there ever a chance WiFi won't wake up for the push/pull of email or am I worrying about nothing?
Keep it connected to a charger or your PC and the wifi will stay ON.
Thanks for the replies guys,
Hopefully data usage will be better than android but I would sill like to be able to turn wifi on all the time is I needed to. In the mean time all email set to as arrives so should cut down on usage a bit.
Lets see what this next update brings
cheers

As the other chap said, plug your phone into power and wifi will not turn off. I nall honesty, wanting the wifi to remain on while the phone is on battery power is a bit daft because it wouldn't last longer than a couple of hours.
Thanks again guys,
Granted leaving the wifi on all the time may drain the batt faster but my HTC legend managed like this with no issues as Android turns off 3g when WIFI is on saving some power. I think we should at least be able to change the WIFI sleep profile like android - 5m, 15m, never etc

I assume you mean that Android turns off 3g when Wifi is *CONNECTED*. I leave my Wifi switched on all the time and what happens is when the phone switches off, it disconnects, but the wifi setting remains *ON*.
Leaving it on is good because when I get home it connects to my Wifi network automatically but while out and about the phone doesn't keep trying to connect, which would drain the battery a lot.
So yeah, make the distinction between Wifi being "ON" and "CONNECTED".
This issue has happend 2 times. It used my 3G data over 90MB for APP downloading!
As you know, the phone won't allow you to download a big APP without wifi or pc connection by design.
Yesterday I downloaded the trial version of Need for Speed(about 127MB) from marketplace and turned on WIFI before that. I just checked the detailed list of my 3G usage yesterday. In that time it downloaded 90MB+ from 3G network in 20 minutes.
I guess the phone turned off the wifi in sleep mode and continue downloading the APP through 3G.
It should be a bug!
Yes, it is a known issue that WP7 turns off wi-fi when phone goes into sleep. To work around this issue, you need to keep the phone plugged in.
Modern wi-fi chips in phones drain less battery juice when you leave it on all the time than constantly off-on-off. Also, it does not necessary use more battery downloading via wi-fi than 3G. I guess MS didn't get that notice when implementing WP7
We can only hope this is addressed in upcoming NoDo update.
Pretty sure this feature isn't designed like this to save battery while connected to a wifi network, I'm sure it's implemented with this design to save battery while you AREN'T in range of one of your networks, rather than having the wireless chip constantly poll for networks...
As someone else said, just plug your phone into the power outlet and wifi will always stay on.
had the phone over a year now, never had an issue before.
As soon as you turn on the portable wifi hotspot, i loose the 3g/h symbol from the top of the screen and from that no data conectivity?
and as sopon as you turn the wifi hotspot off, it regains an internet conection
Any ideas, ive not installed any apps recently, as far as i can remember?
Do you get an internet connection when another device connects to your phone's wifi hotspot.
If you are able to connect, then it must be working, as it's the 3G signal that the phone uses to connect the wifi to the internet. It might remove the icon, but if you can connect then it's fine.
nope, can conect my ipad to the DHDs hotspot but no internet.
the same for when i turn the hotspot on, cant brouse anything on the phone as no data conection
still not sorted this, anyone else got a aide or something to sort this?
First post (longtime lurker)
I've got the same problem here although this has only started happening in the last couple of days. The phone's data connection is fine until you enable the wifi hotspot at which point the connection is dropped to the phone, connecting any devices to the phone is fine, they get an IP address and can ping the phone directly, but beyond the phone there's nothing.
Rebooting the phone does not help.
The only app I've installed recently is Google Shopper.
Out of curiosity Fil what ROM are you using? I'm on RCMix3d Runny 3.0 which is based on Android 2.3.5 and Sense 3.5. I'm looking at switching to an ICS build pretty soon.
It also looks like we're on the same network although I think that's just coincidence.
yep sounds exactly the same issue,
as for rom, still on t-mobiles original 2.50.110.5 Adroid 2.3.3
was thinking of flashing something custom to see if it solved the problem
I've just flashed IceColdSandwich today at work (it's been a slow day!) and you'll be pleased to know that wireless tethering is working again. I'm on the train home as I type this. It's possibly something in the 2.3 image? I can't really say since we both had different ROMs (mine was a Sensation port). It could just be a bad bit of code in the gingerbread OS that produces this bug on rare occasions.
It may have something to do with the fact that T-Mobile and Orange allow you to roam on eachother's networks. Do you have roaming enabled?
To be honest I'm just stabbing wildly at possible causes here and a flash fixed it anyway. I went ICS but I don't think you'd have to go that extreme but flashing a new ROM overwrites whatever it is that caused this in the first place.
I'm just hoping it's fixed in ICS and won't happen again!
cheers, enabled data roaming, and it now works!
Since the issue, my batterys turned to crap! guessing thats the cause constantly jumping networks, and also data speeds have been very poor lately, was ok when just t-mobile, but orange is poor!
Off to the t-mobile foeums to see if its just me, or others!
