[Q] wifi disconnects when screen off - Samsung Epic 4G Touch

Hello,
I flashed Calkulins ROM a few weeks ago. I have noticed recently that whenever i turn the screen on that my phone is connected to 3G. This is despite the fact that i was connected to wifi previously. No issue with the wifi router. Any ideas or suggestions to resolve this issue.
Thank you in advance.

Settings > WiFi > Advanced (by pressing the menu key) > Keep WiFi on during sleep. Choose "always"

WiFi turns off by itself

Got my sgs3 Sunday and when I got home turned on WiFi and started playing with it I notice that I lose network for a second after about 15 mins and my WiFi icon on the status bar disappear but network comes back on .. but in settings it is greyed out and I can't turn it off then back on till I reboot 0_o...thought maybe after I rooted and flash AOKP it would be fixed but no! I'm on T-Mobile and AOKP..so is it a bad WiFi driver or...? Any ideas?
#*0011# press the menu key. Select wifi. uncheck wifi power saver mode. Its should be green when on black off. Make sure its not on and done go back to home screen. Your phone should reboot the wifi driver and your done.
This method works for 4.0.4 any of the roms. Cm10 doesn't work. Cm9 haven't tried but I'm sure it'll work for u.
Hit the thanks if I've helped!

JB has these wifi issues I was expiriencing the same problems on cm10 as well. (I know not the same but both are jb) I decided to downgrade to the intrigue rom r3. It has smooth transitions. Real buttery and it let me access the wifi power saver mode by down ng the method above. I'll look into aokp and see if I can find a fix for u.

does aokp have a setting like i think TW has where if the wifi signal is too weak it will use network instead?
its called avoid bad connections on cm10

For anyone who has already turned off WiFi PSM, is anyone experiencing this setting turning itself back on? I have turned it off twice today and every so often it turns back on which ends up turning my WiFi back off...

Question: are you rebooting your phone when this happens?
Cuz if you are that's normal on every reboot you have to go back and turn it off again.

I was not rebooting the phone. I am currently trying a different rom to see if that solves anything.
Weird

Well it still keeps happening. I switched from intrigue rom to freegs3. I'm currently using the phone at work and it happened right before my eyes while using Tapatalk... I had to turn off power saver mode yet again
Sent from my SGH-T999 using Tapatalk 2
would the method above work for me? since yesterday, my wifi kept turning on by itself. After I turned the wifi off for like a couple minutes then it'll turn on automatically again. I have the Keep Wifi on during sleep set as "only when plugged in" and it never happen to be before until yesterday. My power saving in the setting menu has always been off too. Please help! :crying::crying:
Install the app called "Wifi Fixer" app to the solve the issue.
Whatever Google did to cause a variety of wakelock problems, having a strong wifi signal seems to solve them. Apparently, wakelocks occur when there are unreliable connections to Google's servers.

Uncheck sprint automatic connection in mobile network in settings.
Settings -> More settings -> Mobile networks -> Automatic Connections -> Uncheck Sprint automatic connection
Thank you sir that seems to be the fix thanks again
Sent from my Sprint GS3
I have done this and it still keeps coming on automatically. The only fix I have had so far is to forget my passwords to the wifi connections I have. Is it possible that the power saving feature is cutting it on. Thanks for any responses.
Whst you need to do is turn off sprint connection thing that shows up th first time you boot your phone. Just uncheck it.

I ended up having to delete Sprint Connections all together. Even with it unchecked Wifi would still randomly turn.

This happens to me aswell. Although it seems to be when I'm close to a saved location..which is often... never noticed it happening at random hot spots that are not saved...

Mine randomly turns itself off. It's done so about 3-4 times in about as many days. For instance, I went to bed last night, with it on (I always leave it on, in fact) and this morning it was in the off position. Not just "not connected" but completely switched off. Anyone elses' phone do this?
Disable the preinstalled "AT&T Smart Wi-fi" app. I don't know if it's supposed to, but it turns off your wifi while the phone screen is off and the phone is idle. I disabled the app in Settings > Applications > All > Uninstall Updated > Disable and have not had the problem since.
I seem to be having this issue with my 5GHz network but not my 2.4GHz network. AT&T Smart Wifi is already gone.

[Q] note 2 wifi issue on at&t

i just bought the galaxy note 2.. love the phone' however i cant stay connected to my wifi for some reason it connects them a minute later goes back into 4g mode please help...
I thought it was the phone so replaced it... same issue how ever it will connect to att hotspots.. go figure thanks
I'd say check your router first. Mine at home is a pain sometimes with my sons' ipod touches plus desktop plus netbook plus tablet plus my phone sometimes it drops. We end up turning it off for a few seconds which fixes it. Overload I guess?
There is also a known issue with the att wifi app. I forget what is called because i got rid of it a long time ago but it seems to be a culprit in some cases a well. You could find it if you search the forums I'm sure.

Had a similar issue... dropping of wifi radio... the workaround when using the ATT wifi manager was to go into the phone's wifi menu and disable power saving... *#0011# select menu... then wifi submenu.
Or.. just freeze or remove the ATT wifi app and use Smart WiFi Toggler from Google Market... works well!

Disable att smart wifi. That works for me.
Definitely a router issue. I use WPA2 PSK with DHCP and I haven't had any issues. I have had problems in the past using WEP with my phones. Once I changed to WPA it was fine. Maybe try that.

Thank you, this worked, I think removing the latest update for AT&T smartwifi did it for me, whatever I now have wifi again.
I'll take a look at Smart Wifi Toggler
