Hi all,
Since my wife updated her a500 to 3.1 she is no longer able to connect to any wifi networks.
There's a few threads around talking about replacing the wpa_supplicant file, but this tab is NOT rooted, and is completely stock. It's only a couple of weeks old. I don't particularly want to root it unless I have to, because I don't have the time/cbf. I've tried rebooting everything, clearing cache, all the obvious things, but it just loops through the connection process.
Is there any way to fix it? I guess a factory reset is the next thing to try, but only want to do that if it's likely to work.
Thanks in advance.

Rooting is less work than a factory reset. And if you swap WPA_Supplicant files, you can connect to ad-hoc networks, like one broadcast by a smartphone. I did it myself last night in about 4 minutes.

Remove the connection from your device.
Reboot your wifi router.
Set up the connection in the A500 again.
Good Luck.

Pretty sure it could wireless tether before the update. I'll look at rooting I guess...have to do it to 2 devices though and support them long term...so not overly keen...had hoped acer would take care of it all.

I'm confused. If you're worried about someone running amok with root, just unroot once you've got it fixed. What's the support concern?

Hi I don't know whether will this help in your situation; I had similar problems when after 3.1 update, the wifi connection fails. I go to setting-networks-wifi-settings. next i will "forget network" the connection that fails, and then I add them manually in the "add wifi network".
after that the wifi is back in working condition for me. Hope this helps.

Got onto Acer today. They barely asked me any questions, and advised a factory reset, and they will contact me when a fix is available. I guess they are aware of the issue. They also advised that rooting won't void warranty unless it damages the hardware. So probably going to go that method.

This just happened to me today out of the blue sense day 1 ota of 3.1 and factory reset did fix the problem. Im very tech savay and did everything I could before doing a drastic last ditch effort of resetting and this seemed to be the only quick solution.

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.

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. See here: http://forum.xda-developers.com/showthread.php?t=1138905&page=7
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
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.

Dude this actually worked, Thanks.
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).
delete this to fix
dhcpd-wlan0.lease

ok before the update my phone never had any issues connecting but since i downloaded the official update that someone posted in the development forum it has stopped working, i have tried both Bionix 1.9 as well as Bionix Fusion 1.0 (currently using this one) neither has helped.
whats happening is the phone finds the wifi, connects to it, and then keeps like restarting or losing connection saying obtaining IP address. I have tried this from my home router as well as my work router neither of which work any longer.
I have also tried giving it a static ip address but then it just keeps losing and connecting (refreshing i guess).
If i try and go to the market or a website while the wifi is connected, refreshing doing whatever it doesnt work at all just shows could not load screens.
I have the same issue, with a stock (but rooted) JI6. The only resolution I have is rebooting the phone.

rebooting the phone for me doesnt do any good, i leave wifi on, reboot and then when its back on wifi still doesnt work. Is it possible to go back to pre JI6? if so have you tried that yet?
You could ODIN back to stock. At least you won't be having this problem and plus you could test to see if JI6 is the problem.
I HIGHLY recommend to do a nandroid backup before anything and save ur apps with titanium backup. :]
You need to rest your wi-fi router ie once it connect for the first time its fine afterwords. I have fixed four of my friends vibrants same way.

I havent done so yet but even if this does fix my router at my home issue i cant very well tell my work and places with free wifi "hey i need you to reset your router"...
well im not sure what the issue was but it fixed when i put rom Bionix Fusion 1.1 onto my phone.
I've just stumbled upon an interesting problem.
My tablet couldn't connect on ANY wifi network unless I entered the IP manually (I have checked on my router an my phone using it as a wifi hotspot). DHCP just didn't work and the tablet was stuck at "obtaining IP adress". The odd thing is that even the bars that show the network strength went from 5 full bars to 1 bar.
It was odd since wifi was on and it worked fine until I charged my tablet. I didn't do anything in between and reset didn't help. What worked in the end was deleting the dhcpd-wlan0.lease under /data/misc/dhcp.
Could anyone point me to the problem or an error that caused this because I'm a little afraid that it wasn't just a one time thing and that it could happen again.
Edit: Oh yeah I almost forgot. My router was acting up (my PC that is connected via cable was losing internet connection). Could it be that it was the router that messed up dhcpd-wlan0.lease and broke my Iconia?
oh, that happen to me. I reset factory and all came back....
I hope that not a problem will happen again....
Maybe a clue.
I went to work with the tablet, connected to the internet who have a different IP 192.168.2.1 and 192.168.1.1
Maybe that screw the files because my other tablet didn't move from home and didn't get the problem.
I'll write a script in Tasker to remove the data periodically if it happens again but I hope that it won't.
I don't like doing factory resets because that literally means a day of work fixing my tablet to my standards again.
i'm having the same issue... have a massive wifi network at work and the access point is 10 feet away and the signal jumps around and will not connect
Just delete the file I've listed and it will work if you're experiencing the same problem as me.

this happen to me too .factory reset for me .....hope never happen in future
my wifi stopped working after i updated to 3.1 but all i did was settings -- wireless and networks and removed my wireless settings and added again as new..and everything started working
permission issues on dhcp file...
Most probably the root cause is a permission issues on that particular file after upgrade... Should not happen anymore in the future.

I don't think that's the case. It happened to me again after I've installed Acer phone disabler. Again deleting the file worked but I was able to recreate it whenever I had an unclean shutdown of the tablet.
Permissions were ok. I've checked. Besides that wouldn't explain wifi working normally after update and then not working the next hour (I didn't even touch the tablet in the meantime).
same thing here. Nothing worked except a full wipe. I wonder where this is coming from?
I'm testing and it seems that the most probable cause is an unclean shutdown.
I was able to recreate it whenever I've used Acer phone disabler app.
Does anyone else use this app so that we can narrow it down?
guy it happen again please try a solution. how can i make a downgrade? where can i find the file to delete?what app i have to use to find it? astro is ok?
I've written everything in my post on page 1. The filename (dhcpd-wlan0.lease) and location (data/misc/dhcp/).
Yes but i can't find the ile with astro...uff reset again....

Use root explorer. I've also experienced the error so I'm moving to a new rom (was using the leaked 3.1 rom).
does anyone know if any of the other custom roms fixes this issue?
im using the leaked acer rom in stock form and used it to upgrade from my stock 3.0.1 rom (Australian version)
But i have to root the tablet before to use root explorer?
Does exist a program with no root access to that file?
edit ok i rooted my tab but i can't find the file to delete but maybe it create when wifi will fail .....i have just to wait thank's everybody for now...

Also having problems connecting to office WIFI...
Hi All,
I am not in the habit of creating new threads. But after searching and reading a lot of other posts I concluded I had to create one.
After upgrading to 3.2 my WiFi connection is lost after a few minutes. I have reset my router after the upgrade but that did not help.
This is what happens: I "cold- boot" my Iconia and after a few tries it finds my Router and establishes a connection. After a few minutes though, the connection gets "lost". It happens to me when I leave my Iconia on. If I leave the Iconia on it tells me after a few minutes that there is no Internet connection. It keeps searching, connecting and disconnecting untill I power of the Iconia. After restart the same occurs after a few minutes. If I shut down the Iconia and start it again, the same thing happens (after a few minutes).
I am using a TP-Link router WR1043ND with firmware 3.13.4 Build 110429 Rel.36959n
Anyone have similar issues? Is there any way to fix this apart from contacting Acer or downgrading to 3.1?
BTW My Iconia has build number Acer_A500_7.006.01_com_Gen1 and has not been rooted or otherwise altered.
Any help greatly appreciated....

Ton's of post about this. just google wifi drop out.
Some have fixed by changing in the router the lease time from forever to maybe a week or day. And that may not be your issue but worth a shot. Some have also fixed by using static ip for the tab. Their are others.

The fix im referring to is applying a smali patch which i think requires root. Changing the router isnt always possible if its not your router and you dont have the user name and password and i dont know how well switching from dhcp to static works but the couple times i tried i still experienced dropouts

Did not think about campus routers and such. I had the wifi drop out with several roms. With security on the router open, I did not get the drop outs, but who wants to run like that. My fix was back to stock 3.1.

After I upgraded my A500 to Taboonay 2.2 (which is GEN_1 of Android 3.2) I started experiencing this issue.
Wifi connection keeps dropping every other 5-10 minutes. After reading this thread I was unpatient to figure out if the proposed solution works for me.
Unfortunately wifi still keeps dropping after I booted with power button adn "-" volume bottom pressed and then rebooted.
I also tried deleting the existing connection manually after that and repeated the same procedure. Even after that when I added wifi network from the scratch it still keeps dropping like it was previously
after the latest updates from asus my transformer will not hold a wifi connection for more than 2 seconds - it keeps trying to obtain an ip address but will never stay connected. i just tried a hard reset and the problem still persists. i can't believe i'm the only one having these issues, but i don't see a specific thread here that talks about it.
is there any way to load a new ICS update or a different rom, given that i cannot connect to wifi?
any help would be greatly appreciated - thank you!

this happens suddenly for me ... this wasn't happen 1 or 2 days ago ... maybe an updated app .... :|
for the hell out of it i was going to reboot my home wireless router and noticed that there was an updated firmware out for it - so i installed the new firmware, rebooted, and my transformer hopped right on. anyone having issues might try sinply rebooting their router. that (and maybe the new firmware?) worked for me...
I was suddenly having connection issues myself. Turned out my neighbor moved the channels of his router onto the channels I use. This is of course after I checked what other routers near me were using and selecting free channels when I did my initial router setup. Perhaps you also have an inconsiderate or stupid neighbor. The free app Wifi Analyzer will show this sort of situation.

My a500 is stock running 4.0.3.
Recently the WiFi has become totally unreliable. It shows that it is connected to my network, with good signal strength, but most of the time none of my apps can connect to the Internet. As far as I can tell it seems to connect on its own every few hours because my email is downloading from time to time while the tablet is unattended.
At any time, I can make the WiFi work by turning it off in the settings and then turning it back on. It will work for a while but before long the Internet connection is gone (even though the WiFi is connected). This is really annoying and tedious. I shouldn't have to constantly do this.
I have lots of other WiFi devices and all of them are working just fine; this includes another HTC tablet, cell phones, laptop, etc.
No changes have been made to the a500 in ages so this definitely isn't due to installing any new software or anything like that. My WiFi used to work just fine until this problem popped up. Now it's a major PITA to use. Yes, of course I have tried power cycling the tablet and that doesn't solve the problem.
Any suggestions would be greatly appreciated. TIA

I haven't tried, and I was hoping to avoid that because I hate having to reinstall all my apps. Hoping there's another option, especially since I may go though with the restore and still have the problem.
I did some more research and found that other devices with WiFi problems were fixed by turning WMM off in their router's QOS or turning mixed mode off in their wireless settings. My WMM is on and so is mixed mode. Anyone think that could be the root of my problem?
Possibly. Try it

That could possible help, if you do not want to do factory reset. There are lots of applications that will save all your applications like app backup and restore or titanium backup.

I'm not rooted and had little motivation to root my tablet.
Maybe I'll use a less sophisticated solution like App List Backup which will at least save a list of my installed apps. And IIRC it's supposed to save a link to the Play store for each app but I din't think I've ever gotten that part to work.
