[Q] wifi issue

My wifi connection often wrong, always in after a period of using, have no access to the Internet. Every time the wifi turned off to open another can get to the Internet, can wifi signal is always full. I searched a lot of method to did not solve, including XDA * # # 0011 turn off on wifi power save mode, when problem solving, but after a while just the same. And with only G mode and so on route, are not solutions. Change a lot of Rom, the kernel baseband all not line.Who's a way to solve?
I am not sure if this is the case but - have you tried different router? My S3 for example has issues when I go to my friend's house (he has some old/er Belkin router). However, when I am home wifi is blazing fast and no issues what so ever (cisco e3000).
my phone has a slight different problem, the phone detects strong signal for all my wifi, but will only save it, and not connect right away, some will not even connect, and sometime the speed is very slow.

I am sure there is no porblem with the router,SGS2 and IP4s with the same router is fine.
I'm getting WIFI problems when waking from deep sleep. My settings are set to keep WIFI on when sleeping only when plugged in, as i find this extends my battery life a little more.
Sometimes it reconnects when waking up, and other times it doesn't and i have to turn WIFI off and then on again to force it to scan and reconnect. If i don't do this and check WIFI, it says it's scanning, but never finds or connects to a network.
Anyone else get this?! I read somewhere about sleep of death on GS2?
There is a known problem with the wifi, I have just changed my phone and so far evrything is working.
been through 9-10 phone with different problems.
Ok, i've tried turning off WIFI power save in the system settings *#0011#
I'll report back with my findings in terms of waking from sleep and possible additional battery drain...
Turning off powersave didn't help on my speeds tho. My SGS2 can pull around 5-600KBs a second, while my SGS3 only pulls roughly half despite being at the roughly same location (ie laying next to each other)

[Q] Force 3G on before leaving WIFI out

Hi,
You probably already noticed that by your self..
When you're downloading something over 3G, and you turn the WIFI on during the process, there is no problem because it authenticates and connects the WIFI network and meanwhile keeps the 3G still alive.. it only shuts it off when the WIFI is completely connected and therefore the download is not hanging off..
Unfortunately it was not programmed backward.
When you are on WIFI and turning off the WIFI to move to 3G, or perhaps when you were at home and now walking away the range and so it automatically disconnects it, so it leaves the WIFI first and few seconds later it trigger the 3G and connect it..
During those few seconds you lose the connection and if you were on downloading process it hangs off..
So I was thinking, why not force the 3G on, connects, and only then, hang off the WIFI..
Any app that can do that? or any developer that might wanna pick up the glove?
I'm sure it will help few others but me..
Thanks ahead!

[Problem] QS-i9300-KK 1.9+

Hi!
I can't post direct to developer forum... so
I have strange wifi problem with this rom. Wifi switch is always ON and settings Keep wifi on during sleep is Only when plugged in. After reboot works everything well. Over night or after few hours when screen is off I turn screen on, wifi switch icon is OFF. It looks like wifi turned off, no wifi networks appears, but wifi works well. When I try turn wifi ON, icon shows in half ON state and works further well. Because of this, I can't switch wifi off. Then suddenly after few minutes/hours (randomly) wifi switch shows ON.

Wifi problem on CM12.1

My wifi doesn't automatically connect when a known wifi is in range unless and until I turn the screen on. Means when it's sleeping, it won't connect to any known wifi. If its already connected to a wifi network and if the screen is turned off after that, it stays connected. But lets say power goes off and wifi disconnects because of turning off of the router. When power comes back, and router is automatically switched on, the phone doesnt reconnect automatically when in standby. It connects immediately as soon as I switch on the display. Wifi scanning, keep wifi on during sleep and all those options are enabled. But it still doesnt automatically connect to any known wifi when in standby...I have to turn on the display for that.
Any solutions?
Same issue on lg g3 and xperia z2
