Wifi connectivity issues - EVO 4G General

I've been having a couple problems lately on connecting to wifi.. well it connects, but I cannot use the internet. It usually only takes powering down the wifi and turning it back on, but it is an annoying issue. This had happened on the stock rooted rom, and on cm. anyone else have or know of this issue and a possible fix?

[Q] Anyone else having wifi issues since OTA upgrade?

My unrooted Xoom does not want to keep connected to my wifi signal since the upgrade. I did not have this problem before, but now if I set the Xoom down for a minute or so, the screen on or not, and pick it back up it is no longer connected. Sometimes I find I am without a signal when clicking on a link just after entering a web site while actively surfing. I have the wifi disconnect policy set "Never." Is anyone else experiencing more problems since the upgrade?
No issues for me so far.
None here

The only wifi problem I have is the kernel wifi driver memory leak mentioned elsewhere. My xoom will eventually reboot itself if left on wifi overnight.

This really sounds like the WiFi driver leak problem as mentioned before. Your symptoms are exactly what I was experiencing, pre upgrade.
The workaround is to not set the disconnect policy to "Never". Since I have turned that off, I have not seen the problem.
Nope... no problem here... tried to restart?

Sorry, no problems here with wifi.

No problems here either.
Thanks everyone for all the input.
I must have missed the discussion on the wifi driver leak problem but will do a search on it. If you don't use the "never" setting, which one do you use? It looks like a compromise with the other two settings as I like to have the email and the internet ready and waiting when I turn the Xoom on.
To another suggestion, I have tried rebooting several times.
After further use, it now appears to be an intermittent problem as on occasion today it has not been dropping out.
Im also having this problem since the OTA with my Wireless tether connection.
The tiamat kernel fixes the wifi issues. Check it out in the dev section
i am running stock xoom non rooted. I too am seing issues occasionally with wifi. I have noticed the signal has become lower since the upgrade. My connection used to he good and now ranks as fair. I have restarted bit he the access point and the xoom no change

Exchange / Wifi Issues

I know that there are problems with Exchange and such, but everything was working fine on my phone up until about 2 weeks ago. I have been running CM7 for quite some time and always left wifi on to connect at work and home. Never had any issues connecting to my Exchange account. Then I started to notice some connection issues with e-mails not coming in, etc. It was very random it seemed, sometimes on wifi, sometimes on 3G. So this weekend I decided to try installing CM7.2 and CM9 and maybe it would resolve my issues. Now I can get my phone to connect over 3G, but if I turn on wifi it will not connect, even after I turn wifi back off, until I reboot the phone. Not sure how to fix this problem, I enjoy using wifi quite a bit and it obviously keeps my data usage lower. Any ideas on how I can fix this? Currently running the latest CM9 beta.
Did you flash any kernel? Anyways try updating now the kernels are fixed today.

Wifi issues after MDL OTA

Hey guys,
Ever since I updated my Firmware I am unable to download apps from the playstore when connected to wifi.
Same issue when using YouTube it keeps saying I lost connection to server.
If I use my 3g I can download apps and watch YouTube but not with wifi on.
I also started getting this problem when I started using a airrave. Wifi still works cause my internet pages are loading really fast when I'm connected to it.
Any ideas? Please help I'm desperate.
I don't know if this is related, but I'm at a hotel in Tampa this weekend, and my wifi keeps dropping the connection, and then after several seconds, it reconnects. It doesn't matter where I am in the room, but my laptop has a nice 4-bar signal and hasn't dropped it once.
Anyone else experiencing this? I'm on stock MDL so far.
Thanks
Quick question. Do you guys have Smart Wifi enabled? That might be causing the problem.

[Q] WiFi issue with Connectify hotspot

Hi all,
Been using my GT-i9505 for a while now completely fine. Used WiFi fine etc. However I've moved back to uni where I don't get WiFi and so I use connectify via my laptop and a wired connection to transmit a WiFi signal. I've used this for a few months perfectly fine for my iPhone and tablet (transformer infinity).
The issue that arises is that my gs4 connects fine and stats connected no issues. The data arrows flash orange and green but the data seems to stop working.
Best example is whatsapp which will not send messages or at best has a huge delay.
I rectified this by turning off Wi-Fi power save which fixed the issue but is bit really a fix SD this literally ate battery like nothing else. So wondered if there is s fix or anything I can do phone or computer side to fix this?

[Q] Data Connection to wifi

I'm using a Galaxy S4 from USC (SCH-R970).
4.3.1
Loaded PAC-MAN nightly build dated 11/16/13
All seems to work very well and I'm quite happy with the ROM. There is one glitch I'm having which I can only assume is from the ROM. Whenever I leave my wifi connection and the phone needs to switch to data, it doesn't. It takes a reboot and then all is well. This is what happens when I leave home to go to work. I don't have a wifi connection at work. Going back home doesn't cause any problems. It happily picks up the wifi again.
Other forums have had some suggestions such as toggling wifi on/off (as in airplane mode) etc., none of which seems to work for me. I need to do a reboot to get back to enabling data connection.
Has anyone else noted this? Is this a known issue? Are there any suggestions?
Thx
I have almost the same issue, for me, I randomly lose data connection, and have to reboot to fix it. I DL an app called 3g reconnect and haven't had the problem since. I don't know a real fix but hope that helps
