First off let me say I love this tablet and have pleasantly surprised by its build quality and over stability. Secondly let me say I am typing this thread from a $299 Acer laptop from Newegg with 5 bars of wifi strength and has never lost connectivity......ever. The frustration I feel from the iconia every 2 minutes saying I have lost internet connectivity is becoming unbearable. I am sitting about 15ft from my Fios Router and I am not quite sure why this continues to happen. I have run the wifi analyzer app and it is all over the place. Is this something that might be fixed with a future Acer update? Does it possibly have a bad wifi radio? I see a number of people with the same issues, however it does not seem widespread. I did have a xoom for a week or so with no wifi problems whatsoever. Should I return it? I am 4 days into my 14 day return window with Best Buy. I feel bad because the xoom I had before this had a bad screen and now I will be returning this for wifi issues. I just want to be sure before I go through the trouble. Thanks for the help in advance! This is the only forums I trust that have educated Devs.

Try a different wireless acess point. Pick up a $35 d-link or similar that is just an AP, and turn off the wireless in your router. I had that problem with a Speedstream modem/wireless/router when I got my Wii, only everything would lose connection with the Wii on. Some routers just suck.
You might try checking to see if your router has a firmware update first.
And just for giggles try turning 'n' off on your router.
Hi
Not related to the Acer A500 but I have the same problem with a Dell N5010 notebook.
At home with a Zyxel WIFI router everything is OK. At work with a D-Link 7000 wifi router it gives me every few minutes no internet access. Everything else (phone, other notebooks) work ok. So maybe it's the router a problem.
Hi there matey!
Dunno if it will help but i had many troubles with different routers over the years. One common thing i did notice was that not all devices gel too well with different encryption protocols. eg...TKIP, AES WPA2.
So have a try changing your wireless security settings or briefly leave it as an open network till you diagnose the problem.
Fingers crossed for ya matey!

+1. I had a problem with one of my Android devices not connecting that was solved by changing encription from WPA2 to AES. Try this first.
You're better off returning it than futzing around with it. You're well within your return date and if it not working, it's not going to work.
I have a FiOS router as well and have no issues.
Solution to Iconia Wifi connect/disconnect issue
Greetings members.
I am not a dev, I'm just I guy who loves his Android devices and now can't function without his Iconia.
I began experiencing the Iconia Wifi connect/disconnect issue this afternoon. After several reboots, I googled and found this thread. A lot of good tips but the issue has nothing to do with routers or WPA, and for the love of all that is holy, don't futz around with factory resets or replacing it. The issue is with the hardware and the Wifi drivers in the 3.1 update.
Thankfully, Acer has heard our pleas and has produced a patch and an update.
Looks like the link was blocked by admins (I have to post 7 more...), so just go to acer.com and navigate to the drivers and downloads section, navigate to the tablet/iconia tab/a500 section, go to Patch and download.
Extract and copy the zip file to the root of a microSD. There is actually a pdf with full instructions in the zip.
Bottom line, follow the instructions in the PDF and it WILL restore your Iconia Wifi.
Once the Wifi is back up, check for updates and there is another update to 3.1.
Apparently the 3.1 COM_GEN2 updates for most all countries had this flaw and these two updates are intended to fix the issues.
Just read through the PDF and then follow the steps and you'll be surfing again.
Thanks everyone for this site. Love the help and the insights. And, enjoy your A500's once again.
There are postings from some Xoom users who also had WiFi issues with the 3.1 update. Since the WiFi problems mainly started with the HC 3.1 update, I think it's safe to say most of the problems have been related to the O/S.
I'm using DD-WRT on my linksys wrt600n router at home and it's worked fairly well.

@Slaught3r - thanks, I've tried all the different roms and was beginning to think it was mine only.
I also get wifi connectivity problems, even after the pqtch.:'( I only got it yesterday, so it may be going back.
Could the issue instead be related to your routers? Maybe the channel you've got them configured on is crowded?
I'm just wondering because, well, I have not had any kinds of WIFI-issues at all on any of the ROMs I've tried except only where the channel has already been really crowded by several routers on the same channel.
Doubt it. I'm not using a custom rom on my A500 yet. Still the stock Acer rom. I have it configured to automatically connect me at home, work, and even at church of all places. Until yesterday, everything worked, then...weirdness. Without making changes to my routers, the patch (and subsequent OTA update) seems to have fixed the issue nicely.
Be sure to follow the instructions contained in the zip download from Acer. If you are on a custom Rom and are having this problem, most likely the dev will need to release a patch based on the Acer patch.
Thanks to Slaught3r for the info about the patch. It is important to follow the directions re: the buttons in the PDF exactly. The directions on the Acer support web site differ about when to release the power button versus the volume button, and those directions do NOT work.
Before you do this you may want to disable your router's wireless security, at least until you get the update installed.
@Slaught3r:
Acer doc suggests the problem was fixed in A500_4.010.10_COM_GEN2.
I am experiencing frequent but short Wifi disconnects with Build A500_4.010.11_COM_GEN2.
Can you tell me what build you applied your patch to and what you are now running? I am trying to decide if applying this patch is appropriate, considering I already have a later build.
Any further info from anyone reading this would be appreciated.

I had the same issue after the update to .11. However I solved my issue without the patch.
On the Acer website, I searched on wifi and came upon this link: "What can I do if I am unable to connect via WiFi after completing an Iconia Tab A500 system update?"
I tried the first suggestion of turning the wifi on and off with a restart. It didn't work. The second suggestion is to do a hardware reset with using a paper clip to the hardware switch. That worked; keep in mind that you need to perform that reset twice. The instructions are pretty clear cut.

I was on Acer_A500_4.010.09_COM_GEN2 (pre patch where Wifi was acting up)
After the recent OTA, I'm on 4.010.10_COM_GEN2
My system shows "Up to date" so there is no .11 for me (at least not yet).
It has been a couple days since the patch and subsequent update from .09 to .10 and everything has been fine for my model. Sorry you are having the issues you are.
Many times the wifi problem is caused by incompatible router software. While you would think Acer would take care of this via software upgrade, they do so only for limited routers, apparently.
I just spoke to Dlink, the manufacturer of my router, downloaded updated firmware, works perfectly for two days.

Thanks for posting this. Luckily I have fixed my WIFI problems with the first step.
At some point my router had a problem that somehow stuffed up Iconia's WIFI. Just rebooting didn't help as it still couldn't connect to any network. Switching wifi off and rebooting did the trick for me.
hi everyone, some days ago I installed the virtuous 1.6, than replaced with a rooted stock 3.1. Since then, when I disconnect from my wifi for a while, getting far away from my router, it happens that coming back into the wifi field the tablet tries to reconnect but after 4 or 5 times it stops trying and tells me the connection is disabled. I see the dhcp service bouncing, no ip assigned. The only solution I've found googlin' around is to rename/delete the file dhcpcd-wlan0.lease in /data/misc/dhcp. It worked. but the issue got back again and again. I wanted to find out the cause and solve the problem once and forever, if possible. It's a pain in the... you know
Here is my topic. There is also one solution to it apart from the one you've found in google (which was probably my topic anyway ).
You're right, it'was your post. I've read it againg but I can't find out which could be the alternatrive solution. Keep in mind that when I got this wrong behaviour the first time obviously I invesitgated the possible causes, and I discovered the inability to retrieve a dhcp IP address either with my wifi router, with my wifi access point 3g and with a tethered connection via Iphone (all of them I normally use when I'm not at office). None of these would work until the uplisted file deletion). Would you be so kind as to suggest me, if you can, the possible solution in more detail (apart from performing a global reset that would be as annoying than deleting the file)
In any case, many tnx for your answer
Currently the common solution is to abandon the leaked 3.1 rom or put up with the bug.
Manually setting DHCP also works but it's usefull only if you'll use the tablet on one wifi. Else it's just a big pain in the arse.
I have same issue with the stock 3.1 rom.
At the end what I did was manually assign IP address for my iPhone's MyWi connection.
It seems mine has no trouble to connect to my home wi-fi network as well as work...
I also get that problem. But now, seems to have fixed it. I have done the followings:
- delete the dhcp lease file
- change the channel of my wifi router to 9 or below
- download the ad-hoc supported wpa_supplicant
Please try if above help you
Hi ppl, I'm having some serious problem with my wify connection getting lost every time since the 3.2 update the wify icon! Goes gray and blue each moment, it's like it lost the inernet from the router. Because of this gtalk doesn't keep connected. Hope y can help me here

I don't have such problems, but i want to point out that gray wifi icon doesn't mean there is no internet connectivity. If you disable sync the icon will turn gray, but you still have internet.
i have the exact same problem with losing connection to the Google server and the wifi icon switching from blue to grey constantly. When this happens my internet cennections also times out for a split second causing downloads in progress to end. I do also believe that it is a bug associated with 3.2. I've tried everything that I can think of to resolve it with no luck too. First I went through all of my router settings and did a wipe of the xoom. It didn't work so I went through the hassel of unrooting, relocking, and starting from scratch on 3.0, and I still have the same problem now that I'm back to 3.2. The xoom did not experience this issue on 3.0 or 3.1 and my Asus transformer is not having any problems running on the same connection, so the only thing left to blame my issues on is the 3.2 update itself.

I agree, my wifi turns off when the screen is off even though I have it set to always on!
I am also seeing some strange WiFi connectivity issues that I did not have on 3.1. The indication goes from blue to grey constantly and does cause a interuption of any downloads. Nothing has changed on my router or Xoom settings and both are set to dynamically assign the IP address. While I can still surf when it is grey, something is just not right. I have tried resetting both the router and my Xoom, nothing seems to solve this issue. This definately seems like a bug to me.
Can anyone confirm this is not an issue with the latest Tiamat kernel? I am currently 100% stock and this would give be one more reason to root.

I just finished reunlocking the bootloader, rerooting, and reinstalling cwm. I am in the process of downloading the deodexed 3.2/tiamat 2.0.0 rom to see if this has any effect on the wifi problems that I have been experiencing on 3.2. If this does not work then I am going back to 3.1 until another update comes out. I'll report back to tell you whether I still have these wifi issues tomorrow.
Unfortunately the deodexed 3.2/tiamat 2.0.0 rom did not help with my wifi issues. I flashed the tiamat 1.1 rom, which is based on 3.1 and now everything is working great. I don't know what my problem was with 3.2 or why so few people seem to be suffering with the same problem, but I'm sticking with this rom for awhile.
Was having similar wifi issues... connection retry messages in Market, failed to load web pages, etc. Additionally, network indicator remained primarily "gray". Removed DCHP reservation from router as recommended in earlier post and problem seems to have disappeared. Network indicator remains "blue" and retry messages have completely vanished. Thanks for suggestion
I think I have solved my issues. On the networks I manage (home and portable hotspot) I set the profile on the Xoom to use a static IP. What is strange is that on networks that I do not have control over (work and public hotspots) I left it as DHCP and I am not having any issues. I was having issues before I changed the OTHER profiles to static. Very strange.
I have opened issue 18648 at google code for this:
http://code.google.com/p/android/is...CP&colspec=ID Type Status Owner Summary Stars
DHCP seems to renew my IP address every 2-3 mins according to the adb debug log. Please star the issue if you are still getting it.
Just chiming in...I have a (new to me) XOOM with 3.2, 100% stock, no root, no funny business -- and I have the exact same problem.
There is a constant shift from blue to grey WiFi connection status icon, and issues with playing games online (server disconnections) and downloading apps.
I watched the log and do not see DHCP re-attempts as a new comment suggested, however.
I will attempt to set a static IP when I am home tonight and see if that fixes my issues there...
I have reached my wit's end trying to resolve my problems, so I'm posting here for ideas on fixing this, any input is appreciated!
When this started I was on stock, rooted, ICS 4.0.3 and had been for months. My wife has a nexus s with the same config and hers works fine.
Last week, my daughters sidekick 4G stopped having wi-fi internet connectivity. I turned her wi-fi off, then back on and it was fine and has been ever since. Later that night, my nexus did the same thing, the same procedure resolved it. Ever since then, my wi-fi will only work for 1-5 minutes after turning the wi-fi on. This is the only thing I can think of that changed that could have caused this. This was the first night we connected her sidekick to wi-fi.
The wifi symbol is up there, it'll be blue for up to half an hour, but won't have internet connectivity for long. One thing I noticed pretty quickly was that even though the grey wi-fi symbol is there, I can't access the router settings at 192.168.1.1 from the phone. I thought the grey wifi symbol still indicated I was connected to the router still, but it's not working. Each time this happens, I can turn wi-fi off, back on immediately and it'll work for 1-5 minutes. It appears that the more I constantly use it after turning it back on, it seems to maintain connectivity longer.
Last weekend, just after these issues started, I visited my sister and my phone operated on her wi-fi all weekend just fine.
When I came back home, my problems started immediately.
Here's what I've tried in pretty much the order I tried them:
I started by uninstalling avast, facebook, and autostarts
selected "Forget network" in access points screen and reconnected
Factory reset
Wipe dalvik cache & fix permissions
see if it worked without sim card in (it didn't)
flash GB broadcom driver
Switched router channel from 6 to 1
flash stock 2.3.6 (wi-fi problems still present)
flash OTA ICS (still had problems)
flash stock 2.3.6
flash OTA ICS
re-root
Flash PixelROM 1.60 LiteTouch
factory reset router (No wifi problems on using open network and default SSID for 30 minutes!)
resetup WPA Personal security and rename SSID same as before
Worked for another 15 minutes or so after this
flashed stock 2.3.6
flashed OTA ICS
re-rooted
Restored nandroid backup - quit working after this step
Factory reset router - worked for about 15 minutes, I decided I was ok so I setup security and SSID as before, then it quit working again
flashed PixelRom 1.60 LiteTouch
flashed stock 2.3.6
Flashed OTA ICS - THIS time I did not restore my google backups from the cloud, fearing that this was somehow restoring something that was causing me problems. It did not help.
Changed SSID on my router and reconnected phone
I have spent countless hours trying to fix this. I don't believe it's the hardware because the router factory reset seems to help quite a bit, works fine on unencrypted default router settings, and it worked on my sister's wi-fi.
I have nmap and wireshark and have a basic working knowledge of them. I have adb setup and usable on my computer. I also have dd-wrt installed on my router and have for years. Is there any kind of IP or hardware logging I could perform with these tools to help figure out what's going on??? ANY help is GREATLY appreciated!!
Well i'm no expert with any of this, but it sounds more like a router issue.. If both your sidekick and nexus have the same characteristics of failing wifi, it cant be the devices..
If you've already reset your router and it does the same exact thing, maybe it is something wrong with the router itself. You said it connected fine at your sisters house, so it cant be any hardware within the phone.. The only thing I could think of is maybe try a different router in your house to see if it works? If that helps get rid of the connectivity issue, then you can just get a new router and be happy with the wifis
I don't think a *hardware* problem with the router would only affect 1 device connecting to it wirelessly. I would think that kind of issue would affect all devices on the network.
Which makes me wonder if there's a setting on the router that may be causing it somehow, or some combination of packets might somehow cause the router to block my phone.
But again, I'm open to ideas here and I appreciate your input. I think getting another router will be my next step if I don't hear anything better by the time I get my next paycheck.

Ohh, I thought you had said that both the sidekick and nexus were having problems connecting. My bad.
But yeah have you changed any settings on it lately? Or messed with anything related to the router? Some setting may be kicking your device off after 5 mins, maybe some frequency setting or something dumb like that, I have no clue.
I know how it feels to have funky wifi, so I was only trying to help. good luck
Have you removed DD-WRT from your Wireless Router and back to stock OS? I had a Linksys router with DD-WRT and after about 3 years it started working so weird it became useless with any device. Had to buy a new one.
BTW, are other devices connecting fine to this router?
As swamp goblin stated, I would try with a new router.
It sounds like an issue on your router (or AP) with mixed client settings. I have had this issue with an old Netgear AP.
Try forcing "WPA2 with AES only" if all clients support it, otherwise force "WPA with TKIP only". If you have mixed B/G/N devices, force the fastest mode that all devices support. I use "G only".
Then remove and re-add the router on all your devices.
Also check for router firmware updates, and if you use DD-WRT firmware, find the Wiki page for your model and revision and use the suggested build there. The DD-WRT database they have is a mess and should not be used!

I haven't removed it. I thought I had a model that couldn't go back to stock, but I WILL be looking into this. The other devices connecting fine are Sidekick 4G, Wife's Nexus S, Acer Aspire one, HP tx2000 laptop, and my wife's HP laptop. I also have my satellite receiver connected via ethernet.

THIS FIXED IT! I tried it first since it was the simplest solution and I've been 4 days with no loss of connectivity since I changed it to AES only, which all my clients do support! Thanks so much!
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.
