Here's the outline of the problem:
I'm able to use the wifi to browse the internet and whatever. I turn the screen off and wait maybe half an hour. When I turn it back on, it says it's still connected to my wifi network, but I can't go to any websites. When I look at my Elixir widget, I see that the signal strength is 0%. The only way to fix it is to turn off the wifi and turn it back on, since there's no disconnect button.
Does anyone else have this problem, and is there a solution?
It's like the phone is half asleep and was about to disconnect from the wifi network, but stopped somewhere in the middle.
Seems to be a major problem for a select few on gingerbread roms. I suffer from it on DSC 0.65. A workaround for it is to use WiFi Reassociate (free on the market). For more information look here:

I've been having this problem for about a week now (no wifi problems at all before then). Occasionally when I try to use my phone to access wifi I'll be unable to access the internet (tested using Opera Mobile), even though I'm connected to the network (AirDroid works fine, my phone shows up in the router settings). Turning wifi on and off doesn't fix it. The only solution that I've found is going into airplane mode for a tiny bit (fraction of a second). This fixes it every time, but it's a pain in the ass to have to do a few times a day.
When this first started I thought it might be related to me having changed my wifi sleep policy to when the screen is off, but I put it back to "never" and I'm still having this problem. There doesn't seem to be any pattern to when it happens. It never happened at college (where I was constantly moving around and switching between different routers), and it happens both at my house and at my friends' houses (where we each only have a single router).
I'm rooted with stock 2.3.4 ROM and a kernel with CWM (but otherwise stock, I believe).
Any ideas?
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)
sorry for my poor english
I have a xperia u no brand no root or anything. I found out that when the phone is connected through wifi - my own domestic line - and goes to deep sleep, after a while - i cannot be more precise since it is never the same amount of time - it loses the connection. It appears to be still connected, since the wifi symbol is still displayed, but cannot receive or send any data. I therefore have to turn off wifi, wait for a couple of minutes, and turn it on again. During this "wifi-sleep" the phone is not aware that is not getting any data, so it won't let 3g take over. I've tried many solutions - change wifi channel, change wifi beacon - but nothing seems to work. Of course I've already set the phone not to drop connection when standby in the wifi menu. the only trick that seems to work is to use apps such as regpon wifi that keep the connection artificially "awake", but this is definitely not a solution since battery drain skyrockets.
thank you in advance
This may seem like a minor issue, but it's driving me crazy.
I always set my Wifi to "Always on" on my devices, so that when I pick up my phone or tablet, it's connected and I don't need to wait for it to switch to Wifi and make a connection. This usually works great except on my HTC Desire. Something to do with HTC's connection manager stubbornly switches to the wireless data (3G/4G) connection even though I'm already on Wifi.
Basically what happens is this: I'm using my phone on Wifi, I put it to sleep, set it aside. I pick it up a second, a minute or hours later and turn it back on. It's still connected to Wifi, but then the connection manager toggles over to 3G for no reason at all. Then a few seconds later it flops back over to the Wifi connection.
Again, this may seem like a minor problem, but when I've told my phone to stay on Wifi, I'd like it to stay that way. Plus, the way it works, I'm usually already in an app by the time it toggles my connections, so I'm stuck sitting there and waiting while it does it's thing.
At one point I used Titanium Backup to freeze one of the connection managers that I found in the app list, but that didn't seem to stop it. Does anyone else know which app is doing this nonsense?
I'm on stock 4.2.2 (or whatever the phone came with). The phone is currently rooted.
Thanks a lot!
