This happens with non-final 3.1 and it is a known glitch. Just update to final 3.1 and problem solved. Otherwise you just have to erase a file in the dhcp folder.

Best regards.

Want to help us out and tell us what file needs to be deleted?
[Acer Iconia A500] BatPenguin:
Yes, you can fix this by deleting a file, but no, it's not a problem with just non-final updates. I had not updated anythinh unofficial, and this happened to me. I got the offial OTA 3.1 update and have been fighting this issue ever since. Very annoying, basically requires everybody to root their device until this is fixed.

I rooted my acer so I could replace the wpa_supplicant file to update it. then when I unrooted it, my wifi wont work either. It just says error and I tried that factory reset and it didnt help either. now I dont know wut to do
[Acer Iconia A500] mulawingalang:
Hi guys! Im new here and I just wanted to share my experience with my Acer Iconia after updating to Honeycomb 3.1

After updating to Honeycomb, it did seem to run faster and better but after how many hours, i wasnt able to connect to any wifi network. That pissed me off... :l

I tried numerous ways to try and fix it, I even tried manually using static ip and reserving an ip address for my tablet and it worked, it did connect but there was no internet.

So I tried resetting my tablet by pressing the reset button beside the usb port. the first reset, no luck, still won't connect but on the second time i reset my device i was able to connect :-)

I suggest before you do a factory reset on your device, try resetting your device first 2 times and make sure to forget the wifi networks as well and try reconnecting again.

I hope this helps! So far I've connected to three different wifi networks and experienced no problem at all. :-)
[Acer Iconia A500] ferds:
Dude this actually worked, Thanks.
[Acer Iconia A500] MrBoingy:
Yeah, thanks for that.

Mine was fine for a while after 3.1 update and suddenly lost wi-fi.

The guy above is correct.

I deleted the wifi details (ie long click, forget).

Reset Once. Still broken.

Reset second time. Enter password.

Working.

Weird. (my tablet is unrooted, standard OTA 3.1 update).
[Acer Iconia A500] ando.rulez:
delete this to fix

dhcpd-wlan0.lease

/data/misc/wifi/

Using rooted filemanager with press long, then delete.

Good luck...
[Acer Iconia A500] ozymandious:
Dude I so hope this works I'll go try it now.

Report back in a few...

Edit/update:

...after a few...

Thank you soo much I rebooted 2x and it worked, back on WiFi again.

NB wait for a full restart be for hitting the restart button again.

1: I reset n saw the Acer splash screen and then punched the button again = didn't work

2: reset on waited till i saw the lock screen then hit reset again = Wifi working again
[Acer Iconia A500] ando.rulez:
Should be this folder:

/data/misc/dhcp/
[Acer Iconia A500] mulawingalang:
to everyone,

when doing the 2 resets, please make sure that you let the tablet load with every reset you make.

1. forget the network you are trying to connect to and try to connect, if it doesnt...

2. make the 1st reset, and let your tablet load...

3. check if it connects after it loads if it doesnt...

4. do the 2nd reset. let the tablet load and see if it connects.

in my case, it connects after the 2nd reset. I hope this helps! :-)

Double reset totally worked!

Great find! saved a factory reset!

Thanks!
[Acer Iconia A500] simonsgray:
Double reset, all the way...

..to the sky!
[Acer Iconia A500] hardslog:
Thanks, The double reboot did not work for me so I had to use this method. Funny thing is that it was working this morning just fine, I was on skype for about 30 minutes and at lunchtime I tried to connect to a different AP and it wouldn't work. Later I rooted the tablet, remoted the file, and things started working again. I unrooted the device and shortly after the problem came up again so I had to root again and delete the file. I'm using the official OTA update: 4.010.22_COM_GEN1. It worked fine for about 5 days until the problem started. I also notice that after this wifi problem all my widgets disappeared. Very strange.
[Acer Iconia A500] jpsheridan:
Holly Crap! Thanks mulawingalang!!! Your suggestion actually worked for me to resolve my issue as well.. I choose "Forget" home network connection and on the second reset it finally connected back up.. Awesome discovery.
[Acer Iconia A500] dr1337:
This is not a permanent fix. The problem actually lies deep within the compiled frameworks. I've just finished a new ROM with numerous bug fixes including this WiFi issue.

Not sure if I'll release it......
[Acer Iconia A500] MrBoingy:
Yeah you're right.

This morning I can't log onto wireless again.

Tried double reset. Still no go.

Tablet without internet connection is quite useless hahaha.

So, what next?

A factory reset (not that I know how to do that)? If I do that, what do I lose?

or

Root my tablet (not that I know how to do that) and use a file explorer to delete that file?
[Acer Iconia A500] MrBoingy:
Right, I take that back.

I gave it ANOTHER go.

Tried to log on... all it did was Obtaining IP address/Scanning repeatedly.

I long clicked and FORGET.

I reset.

When the tablet came back on, it connected immediately to the connection I had just forgotten.

Can't complain cos it's working but I'm guessing it raises some issues... whatever those are hahahaha...
[Acer Iconia A500] rmingee:
Neither the double reset nor the file removal worked for me. It didn't recreate the file until after a reset when I removed it. I guess the only remaining option is a factory reset at this point? Or is there a specific order for the file removal and reset that I'm not doing correctly? Someone said something about replacing a different file, but I didn't see details on that approach in this thread. I can continue to connect fine to my wireless network at work.

Any and all suggestions would be much appreciated. I really would rather not factory reset, even though I have Titanium Backup, so it would be relatively easy to restore.

-- robert
[Acer Iconia A500] rmingee:
I have tried just about all possible combinations at this point. What I really suspect is that the problem is simply re-occuring instantly with my home network for some reason, because the lease file does get reset/recreated after a couple of resets, and I think I got very brief connection once, but then it went away again. That leads me to wonder if even a factory reset would actually fix it, or if I am simply stuck until they resolve this problem. ARGH! At least I can connect at work so I can update apps.

-- robert
[Acer Iconia A500] rmingee:
It took a factory reset followed by a reset button reset before setup to FINALLY get it to connect again. Something is very wrong with this update. Makes me want to track down the stock 3.0 ROM...

hi,

the problem exist since a long time.

I personal notice this with the 4.010.22_COM_GEN1 and the 4.010.30_COM_GEN1 Version on diffrent A500.

But it's not a device issue, many other Android Versions and devices are involvet.

I tried many things, the best of all:

root the Tab with: iconiaroot-1.3.apk

Terminal for move File: Android_Terminal_Emulator_1.0.4.apk

su

cd /data/misc/dhcp

mv dhcpcd-wlan0.lease dhcpcd-wlan0.lease.org

restart WIFI :)

thats it, works well on both Version

[Fascinate Q&A, Help & Troubleshooting] efan450:
I have read everything I found regarding various issues on cm7 and have not seen any info on visual voice mail.

I use verizon's visual voicemail service and I flashed one of the earlier cm7 build and noticed it didn't work...then I went back to comm rom (mainly because of the deep sleep issues) and it (vvm) worked fine.

Fast forward a few days and

Cm7 has the deep sleep issues resolved...jt is the man! So I'm back on cm7 and visual voice mail isn't working...when I say not working I mean when I launch the app it just sits on a screen that says it verifying my subscription and then says I have no data connection..I've tried wiping data from the app, rebooting, un installing and re installing all with no luck. I don't know if any one else has this problem or not, but I guess what I'm looking for is your opinions on whether or not this is something that possibly will be fixed once this is a fully functional rom or will this always be an issue...please keep in mind I'm not complaining, blaming the rom or looking for an eta , I'm simply wondering if I should cancel my vvm service with verizon or wait and see if its fixed when the rom is no longer a"test build"? which I personally think its already past that! I can still get my voicemail the old fashioned way so its not a huge issue, I just didn't know if I was alone with this problem or if some one may know a work around to get vvm to work...if the answer is no or to just be patient...I will do just that. Thanks in advance for any info/opinions!

Carrier apps typically do not work on cyanogenmod, visual voicemail is no exception. My advice: cancel it and switch to Google voice as it will work on any rom, and its free.

[Thunderbolt Q&A, Help & Troubleshooting] meijerbrantm:
Does any TBolt rom support it?

I think I've read about the stock one is the only one to support it after root.

Is it just something missing in these roms or is it something else?

I've tried these on some of the BAMF and a few other roms, but I haven't found one that works yet.
[Thunderbolt Q&A, Help & Troubleshooting] sg1dan:
yeah i haven't found one either. the wired tether app doesn't seem to work for me. i am now on synergy 3.0 nightly and have to use wireless tether.
[Thunderbolt Q&A, Help & Troubleshooting] RunNgun42:
The wired tether app only works after you have downloaded HTCsync for your pc. Windows needs the modem drivers located in that file to properly connect to your phone.

Or you can download PDAnet/EasyTether and they basically do the same thing.
[Thunderbolt Q&A, Help & Troubleshooting] meijerbrantm:
this isn't the case. my Evo (work phone) works just fine wired tethering, but my thunderbolt does not.

pdanet/easytether isn't free if i want to use secure sites... I'm technically okay for paying for the software, but I'd rather not when there are free resources like this out there that do indeed work on other devices.
[Thunderbolt Q&A, Help & Troubleshooting] setexascustoms:
Doesn't CM7 have wired tether? I could be wrong, no matter how many times I try I always end up back with Sense. But it seems like I remember it does, if you don't mind an AOSP ROM that is. :D
[Thunderbolt Q&A, Help & Troubleshooting] RunNgun42:
Ok apparently the drivers are part of the VZW software that tries to install whenever you connect the phone. It didnt appear to install any software to my pc, just the drivers necessary for the integrated wired tether mode to work. I didnt see any popups or warnings about incurring additional charges for doing this, so I assume it's ok.

[Verizon Droid Charge] nitsuj17:
some folks had requested the mod to change boot logos (the samsung splash, or whatever it is on the charge)

i can do it, but i need the param.lfs files for whatever build you want it for (ee4, ep1f, eg2, w/e)...if you someone can link them and list which build each is for, i can do it and write up the how to

the param.lfs would be in an odin tar....(if you use heimdall you are already familiar with the structure and files im sure)

thanks in advance :)
[Verizon Droid Charge] Daemonax:
I found one in the ED2 stock recovery. There hasn't been one in the GB leaks, but I copied out my .lfs folder from stock EP1F and attached it in case it helps.
[Verizon Droid Charge] letsgophillyingeneral:
I'm assuming this will only change the first logo that appears and not the boot animation itself, correct? What is the problem with custom boot animations anyway?
[Verizon Droid Charge] nitsuj17:
yeah i just realized that the param.lfs might only be in full factory leak odins...i dont know which ones you guys have of that, but thanks, for uploading what ya have :)

yes, this will only change the splash/boot image...custom boot ani support is kernel dependent...must be done by a kernel developer
[Verizon Droid Charge] nitsuj17:
if anyone on ed2 is adventurous http://www.mediafire.com/?id44v16v4h34344

*Enter download mode on your phone

*Install heimdall driver (if you haven't already)

*Flash new param.lfs IN HEIMDALL IN THE BOX THAT SAYS PARAM.LFS, NOT FACTORYFS (if you are using frontend)

*Reboot normally, if it boots into recovery/cwr just reboot again

*Ignore garbled text on bootup (you may even see weird 8 bit cwr logo spread all over screen, no big deal)

*Copy your new boot jpg to the root of your sdcard...must be named logo.jpg

*Open terminal

*Enter these commands:

adb shell

$ su

# cp /sdcard/newlogo.jpg /mnt/.lfs/logo.jpg

#reboot

should work fine, otherwise you may have to remount after su and before cp...but im not sure the command because im not sure if the partitions are the same as the fascinate (mount -o remount,rw /dev/block/stl6 /mnt/.lfs)

If someone can do one for EE4 that would be great. I really liked having the DROID logo on the boot screen on my DX.

Oh yeah I'm also running stock Rom with latest UK updates.

Thanks,

John

UPDATE: Yeah it is definately the facebook app that is the problem, now that i've uninstalled it i have only lost about 1~2% in the past 8 hours of idle time :o It seems that there is a problem with the official facebook app which keeps phones awake permanently, even when notifications are disabled within the app. It also seems to affect all android devices having done a few google searches of the issue. Now that I know what the problem is I may reinstall and have a fiddle about with it as I did really like the integration with the contacts list on my phone (display pictures auto appearing for all contacts, etc)

When I have my phone locked the screen stays on.
[Galaxy S II Q&A, Help & Troubleshooting] jbm1991:
when your phone is locked the screen stays on?? so the display is on permanently? or does it just say it is on permanently in the battery thing?

For my phone it says the display is off, just that the phone is awake permanently.

quick update though, I restarted the phone and charged it up to 100% and ive just had a quick look at the battery thing and the awake solidly problem seems to have gone for now. So i presume it must be an app i've used which has some sort of problem when it comes to closing itself down and its keeping my phone awake for some reason.

John
[Galaxy S II Q&A, Help & Troubleshooting] jbm1991:
Actually no, i tell a lie. I've just looked again and the graph has changed and is now reading the display as being on, even though it isn't, and the phone being awake for the past half an hour. which is how long its been running off this charge so far, still 100% though. hmm strange.

[Galaxy S II Q&A, Help & Troubleshooting] d3l1:
I'd like to do that, too, but I still couldn't bring myself to rooting (still worried about the warranty with the custom counter)

I'm glad it worked for you, though my phone is hardly awake and I still have the fb app installed and it is set to sync every hour. That app is buggy like hell, maybe uninstalling it will give me even better battery life, who knows. If so, what's a good alternative to the fb app?
[Galaxy S II Q&A, Help & Troubleshooting] jbm1991:
Seriously, root your phone, you won't regret it in the slightest. And you can just buy a jig off ebay for like 5 dollars or pounds or whatever which resets the ROM counter after you've reset and flashed the original non-rooted stock ROM which essentially revalidates your warranty. I was a bit aprehensive too, but using ChainFires guide it took me like 5 minutes and couldn't be easier.

As for an alternative to the facebook app, i've just bookmarked iphone.facebook.com in the web browser and stuck the bookmark as a link on my home screen. Works just as well, although no automatic notifications in the notification bar, you have to look manually on the web browser. But that's a sacrifice i'm willing to make seeing as facebook was destroying my battery life. I've been using my phone quite a bit today and i've only dropped about 10% so far.

But yeah, root your phone and freeze all the hubs and wifi sharing and wifi sharing manager and your battery life will get considerably better.

If you need a hand rooting give me a shout and i'll help :)

John
[Galaxy S II Q&A, Help & Troubleshooting] conantroutman:
Something like "Seesmic" or "Tweetdeck" will allow you view facebook feeds...

[Samsung Infuse 4G] dajeoo:
What is the purpose of staying awake?
[Samsung Infuse 4G] hwaters:
probably to stop the screen from turning off while you're using the phone when it's plugged in.
[Samsung Infuse 4G] Frooty:
It also seems useful when reading stuff online. There are so many times when I'm reading a really long article or something and since I'm a slow reader I have to keep slowly scrolling down the page every time the screen dims to make sure it doesn't turn off.

Turn your google mail sync off then back on again, and ensure your sync is always running, that is as best push you will get.
