WiFi randomly fails to connect after last update

I've had my Transformer for about 2 months now and my WiFi connection has always been reliable and robust, but ever since the last OTA update (8.4.4.11) it's gone flakey. I know the problem is not my wireless router since WiFi was working great before the update and I have lots of other devices that connect without any issues.
At least once or twice a day after resuming from standby, the WiFi icon stays dark and no amount of trying to reconnect will get it back. After a few tries, I can actually watch the checkbox for WiFi settings toggle on and off repeatedly by itself.
I've tried changing the WiFi disconnect policies, closing down apps, and stopping non-critical processes but the only thing that fixes the issue is to power down and restart. WiFi will then work for awhile but eventually goes out again.
Anyone else seeing this?

same thing here =/

same here and i'm getting piss off at the fact that new updates is screwing over my wifi connection.

FWIW - it's also discussed in these 2 threads and is worked around by giving your TF a static IP. Not ideal, I know, but at least it will get y'all working.

there has been issues with other tabs and OTA upgrades with WIFI. Try brouse in the A500 forums. There was a file to delete that fixed the issue. Must have root access.

That's kewl and all but what if you connect to different AP's during the day. I access through my EVO 4G while at work and then access my home network when I get home. This may or may not work. I'll have to see when I get my TF on Thursday. Thanks for the quick links though.

You can also increase the dhcp lease time in your wireless router, it also works for me.

Download WiFi Analyser, which will show you, which IP data you need for static configuration.

Not exactly the same issue and I already set up static IPs for all the devices (32 of 'em!) on my wireless network long ago.
I did find that one particular app was probably the cause (PCFile Sync) and since replaced it with another having similar functionality, but I still very occasionally lose WiFi and have to reboot.

I've been following this issue since I started having it on the 3.1 update when I unboxed the thing, so I'd really like to understand what issue you found with PCFile Sync, or at least what led you down that road.
Up to this point because of my specific goings on I've been thinking it was more a DHCP/routing issue and not in fact a WiFi/connection issue - i have strong connection before and after whatever the event that shuts things down is, just no traffic.
A little more info here as well - http://forum.xda-developers.com/showthread.php?t=1191792

The behavior I described in my initial post (watching WiFi toggle on and off in settings) seemed to suggest something was blocking or interfering with the normal connection after resuming from standby (I have my WiFi disconnect policy set to turn off WiFi when the display is off).
So I just started closing down apps that had WiFi access and when I killed PCFile Sync (which I use to sync files between the TF and an NAS), the problem went away. I'm now using FolderSync Lite which doesn't seem to cause any issues, although on rare occasions WiFi will still loop for awhile before connecting.
This never happened in HC 3.1 so I think it's a vulnerability in 3.2 under certain conditions ... and those not using a static IP on their LAN are probably seeing something similar happen.

You know, after using my TF after the update, I think what this wifi bug is really just a fix gone wrong. Maybe it's some condition set to turn on wifi only when in use (to save battery life, or allow certain tablets that won't go into deep sleep to go into deep sleep or something like that) but it's set with some super sensitive conditions that make it turn off unless there is an actual request for internet?
My bar goes from blue to grey/white after a minute or something, but I can seem to always access some webpage when I click it from an app. Hmm.

This happens to me with 3.1 randomly, though my policy is set to keep WiFi alive and I never used this PCSync app.
In my opinion the Android Broadcom WiFi card driver is buggy, because the SGS2 with android 2.3.3 has similar problems and also a Broadcom card.
So I guess it has nothing to do with the Android version, but is a buggy WiFi driver. I remember, that I had similar problems with an Intel card in a Toshiba notebook years ago and it was fixed with a driver update.
The question is, who develops the drivers, Google's Android team or Asus & Co? I guess the later? If it are the manufacturers, I find it strange, that Samsung has similar issues.

+ 1 on this very frustrating bug; since upgrade to 3.2 it happens every now and then ; as I did not install any new Apps I assume that this is just a very annoying 3.2 bug...
Anybody with any solution plz?

A german TF owner reported in a german Android forum, that he phoned Asus support about all well known 3.2 issues and they told him, that a firmware fix will be released by OTA next week.
Knock on wood that this is true.
So far ... static IP.

Wifi decreases in speed overtime

I have the wifi only model of the Xoom and have noticed that my wifi speeds decrease if the unit is left on for a couple of hours. It will only get back to full speed after rebooting. For instance, after bootup I can get up to 20mbps. After an hour or so, I'll drop to 3-5mpbs max. I tried not running anything after bootup except for the speedtest.net app and get the same behavior. Just wondering if anyone else is having this issue. I am running Honeycomb 3.2. I have searched on this forum but no one is having any similar issues, just wifi dropouts. I don't have that problem. The only services running at the time of bootup are Music, Thumbkeyboard, Minimalistic text, Maps and Google Services.

Your router will affect that. I had that issue until I bought a real high speed router. Also check your router settings for the through put speeds. You can set that to 54mb or higher and change to channel 11. See if that helps.

I have the D-link DGL4300 router. That's a high end router. But I'll try setting it to Channel 11 to see if that helps. I have the same issues using the wireless at work as I do at home. Hopefully this change helps.

Changing the channel would only improve speed if the channel you are currently using is crowded. Channel is merely frequency. As for slowing, it is probably your routers qos.

Yeah that doesn't work. How do I change my qos?

I highly suggest setting up a static IP address if you know how to do so. A static IP is a more direct connection to the device. In other words: Auto settings will do everything by itself to the best of its ability, meanwhile a static IP says that it will go right here to this specific device right now. Thus, you will have a more solid connection to the device with an internet connection.
Setting up a static IP address is really easy, you just have to know a little bit about your router, and know how to work with setting up custom IP addresses. Once you learn it, you would apply that to all of your internet enabled devices, not just the Xoom.
I have all of my devices set up this way, Xoom included. It runs smooth as butter like always.
Setting a Static IP Address in Windows 7
This website has some basic knowledge, although it is for Windows 7. The same rules apply to any other device as well. You'll have to check your wireless router settings and see what devices are connecting to it, and what their IP addresses are. Once you know that... it should be pretty easy to get things rolling. The other basics like subnet mask, and default router are explained in the website.

This is great advice for when the AP you're connecting to has trouble negotiating DHCP, but it seems to me the OP is talking about link speed.
OP: there's a memory leak in some versions of the wifi driver that can cause the symptoms you're seeing. I've seen it a few times even in 3.2, but toggling wifi usually cures it.

I bought a 300mb netgear and it fixed my issue at home. At work is a diff story. Max speed on those routers is 54mb and it pauses all the time. Seems to me the xoom was designed for speed and the cheaper routers can't keep up with the data.

your problem might be cache full as it is ok after reboot. try installing a cache cleaner ng apk from market. it can schedule a auto cache clear daily.

Ok. I think the problem that was sucking down my wifi speeds was a god damn live wallpaper. I downloaded the one called Shadow Galaxy from the market. After I rebooted yesterday, I had changed the wallpaper to a plain one. It's been about 20 hours so far since my last reboot and I'm still getting 15 to 20mbps! I'll keep you guys posted.

I kinda figured as much, but y'all seemed to have this down already. Figured I would offer up some useful info to make a more solid internet connection.

If none of the other options helped, in your routers settings (generally 192.168.0.1), probably advanced then quality of service, you can probably turn on or off the native qos, or make an exception. I'm not sure, Im not familiar with d-link software...

Im having the same problem with my Xoom (3.2), after been conected some time to a wifi speed decreased a lot! What i do is turn off then turn it on again, that fixes it
It there a fit for that?

wouldnt this only be the cause if the live wallpaper connects to the internet... i have one which just uses photos from my sd card... maybe we could try restricting its access to the internet and maybe that will have an affect? I dont know how to restrict internet access though

Just switch it to a stock wallpaper for now and see if that works.

im not using live wallpaper, just an stock one.
I just did the process to restore full speed again, this is happening in all placess i go, at least once at day, i think is a honeycomb (3.2) problem, not just a live wallpaper :-S

Overcome rom wifi problem

To my understanding the 3.2 update was pulled for the dhcp issue with wifi. it seems though I'm having the same problem with the overcome rom. The can anyone confirm if hey are having the same problem?

This issue happend to me as well with the official OTA update. The main story is pretty much like this:
The tab updated over the air, to 3.2 stopped being able to connect to a DHCP WiFi network. Basicly this is a network that gives your tablet the IP configurations automatically. This goes for almost all modems and routers out there.
To "Fix" this problem, you have to manually setup your connection from your tablet, putting in the right IP adress numbers to match your router, etc. And I also belive that I had do remove the DHCP function from my router.
I couldn't handle this and basicly wanted to "save" my tablet, instead of downloading yet another update from Samsung, that might be currupt. So I Flashed "Task650" 3.2 ROM, it's really quite nice and I didn't have any issues since then. It might be that the overcome ROM failed to fix this part, or that you got a bad flash?
Greetings.

I had the same problem and then did a restock and reflashed 3.2 and it solved the problem.

[Q] wifi issues - will not hold connection

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.

[SOLVED] Connected to Wifi but no internet connectivity

I was having Wifi issues on the 6P. Connected to home wifi but no internet. The thing is, the wifi would still work randomly. It's possible that it works most of the time but as soon as I go out somewhere and out of the home wifi range, it sometimes messes up when it tries to reconnect to the network.
And yes, I realize it may not be a phone issue but maybe the router (Asus N66U with Tomato firmware).
/edit - well, I spoke too soon and I guess it's not the static IP causing the wifi issues.
It turns out it was a firewall app called AFWall+

Might want to update the title then. Although I do have that issue where when I get home i have to turn off/on wifi on my phone to get a connection.

It's hard to say. This problem seems to be random. I haven't experienced it today. The only change I've made is update Cataclysm and ElementalX to the newest versions after installing the latest Android security updates. I can't guarantee I won't experience the problem again since it was happening on and off before.
No amount of disabling wifi and restarting my 6P would get internet connectivity back when the problem is happening. It just seems to start working again randomly. Is that what happens to you too?

I can't really explain it. It says I am connected to WiFi, and speedtest still works along with web browsing most of the time. But the main thing that doesn't work is my google account syncing (so emails wont appear, or delete from ym account when I do so in the app) as well as the play store not downloading or updating apps. I keep seeing issues with 5ghz, so I am gonna try connecting to my 2.4ghz as well as setting the wifi to 2.4 only, as of right now it is working. But its like you said random, and when it does happen restarting is no help. I also just set my phone to use a static ip as I heard that helped some people. I just found it weird that you have the same router and had issues.
Im on Pure Nexus with ElementalX latest update, don't have the latest security patch though.
Its only my Nexus 6p, and it seems I have no issues when I am on my girlfriends wifi. SO I am hoping the 2.4 and static IP solve it, however that sucks cause I want to use my 5ghz, as there are less devices and I get a more solid connection.

I found out it wasn't a problem with the phone or 6.0.1 at all. It was due to a firewall app called AFWall+. I figured it out when I realized internet connectivity would return when I disabled it.
Now, you might think that the app should have been one of the more obvious causes. That's true... but I had it set to Blacklist mode to only block certain apps. Internet wasn't working system wide and it only occurred on Wifi whereas LTE worked fine. So, uninstalling it seems to have fixed the problem and it hasn't happened since. Perhaps it's an issue with systemless root.
