[Q] Wifi connection is not working properly on S2 - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have a year old factory unlocked S2 which was working fine till this morning. All of a sudden, I see that even though the WiFi shows as connected, there is no internet connection. I restarted it quite a few times but to no avail. The software is up to date and I have not done anything fancy with it ever. No rooting, nothing...
Can anyone please help? My other devices are connecting to the same wifi and working fine...includes my windows laptop, mac, iphone and ipad...

I tried it, in fact removed all the known wi fi networks, then shut down phone then connected back to the wifi... even then, no internet... the small green arrow near the wifi symbol shows that data is being sent, but the orange arrow that signifies that data is being downloaded/received hardly lights up...
chrome does not open the page, foursquare does not connect, even the default accuweather app does not refresh... any idea?

Just a thought, is your Wifi router connected to the internet? Connectivity issues?
If you can afford it, try doing a factory reset. Also try connecting to some other router. If it was working till morning, and the phone didn't fell down/experience damages, I don't get why it stopped working all of a sudden.

Thanks Sikander... at the end, I think I will try a factory reset.. for nothing else is working...the phone has never been dropped :fingers-crossed:
but like I said, all my other devices are also connected to wifi and they are working perfectly so I would not think that it is a problem with the router...
thanks again... but pls let me know if you think that anything else might help

Mozart not finding my (non-hidden) Wi-Fi network

My Mozart for some reason can no longer find my home wi-fi network. It was working just fine 10 minutes ago and now, all of a sudden I unlock it and theres no Wi-Fi connection. Checked in Settings but the network doesnt appear in the list anymore.
The network is fine as im using it on my laptop now to type this and on my iPad. I tried switching Wi-Fi on an off several times and also rebooted the device many times too. I also tried adding the network like it was hidden, but no avail...
Any ideas?
UPDATE (PROBLEM SOLVED)
Okay i got the problem fixed, it wasnt a Windows Phone problem, my router suddenly decided to change the channel it was broadcasting on, it was 6 before, bumped it to 11 and now the phone is able to connect again XD
Are you running Mango?
I had problems connecting to my Wi-Fi pre-Mango when the SSID was hidden. Mango, however seems to connect fine in this scenario.
Apologies... I just re-read your question. I seem to have mis-read the NON HIDDEN network.

Yeah im on official Mango, forced it through Zune... And im certain my network isnt hidden...
If you go to Settings -> Wi-Fi -> Advanced is the network shown as a 'Known network'? If so, remove it restart your phone and try again.

It was listed and yeah, i tried that too, didnt work.
I think i'll hard reset the phone to the original pre-NoDo ROM and see if i have the same problem, if I do then it might be a hardware issue? Good thing I still have my warranty...
[UPDATE]
I just reset the phone, lost all my data for nothing -.-
[UPDATE 2]
Restored the phone to 7008, same problem... I'll reset the modem in a few hours. I hope that's the problem because the phone has no problem finding and connecting to networks further away from me...
Have you tried enabling the SSID again in the router setup then connect on your handset and finally hiding it again through the router?

S3 not automatically connecting back to WiFi

I’ve recently upgraded from an S2 to an S3 and have a slight issue. When I’m out the house and connected via a data connection (O2 giffgaff) all is great however when I get back home or to a saved wifi spot my phone will not automatically connect to it whilst the screen is off. I have to litterally wake the screen from sleep/lock mode to the home screen where I can see the data connection still on then soon after it will switch to WiFi with the connected confrimation message.
Surley I shouldnt have to wake my phone when coming in range to a saved WiFi point in order for it to connect to it, my S2 never had such issue and automatically connected to saved points. Earlier I went down to the shop and used the data connection whilst there, come back to work and hadn’t woke my phone for about half hour, turned it on and it started connecting to the wireless. The connection still works when the phone is in sleep/lock screen as I still recieve emails etc so it's not cutting of data connections completely when sleeping so I'm a bit puzzled by this, I haven't tested this vice versa WiFi to data but I'm sure there must be a simple setting somewhere.
Any help greatly appreciated.
I noticed this earlier on, I was out all day, returned home and wifi wouldn't auto connect, I had to disable and re enable wifi
Sent from my SGS3 on Omega v9.0 using XDA Premium
It's strange I can't quite work it out, I tested it the other way round and it seemed to automatically connect to mobile data when there was no saved WiFi in range so it only seems to be an issue with auto connecting to WiFi.
I'm going to try a few more tests.

You could try deleting the saved network and adding it again. It has happened to me before and that has fixed the problem.

Problem with cm9 and wifi

Hi i went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

I have same problem. I have SE xperia mini with CM9. WiFi worked fine until yesterday. Now phone can't connect to AP (full signal - try connect -> signal drops down), but sharing 3G internet over WiFi works fine. I cleared dalvik cache, but that didn't help.

Replacement phone from Sprint. Can't connect to any WIFI networks...

Yeahhhh so my old phone was having some issues so Sprint got me a new (refurb) LTEVO. Phone looks great, but it doesn't connect to wifi no matter what I do. I've already tried factory resetting, setting to 2.4ghz only, and nothing, wont connect. Tried on my WPA2 network at home, as well as our WPAe at work. Exact same symptoms. The phone will randomly see the networks, so naturally I select it and enter my credentials. Immediately the phone will say the network is out of range. A few minutes later it'll pop-up in range again, I try to connect, same thing.
I thought it may be related to the wifi antenna on the phone but it seems to be okay. I already did a factory reset and no change.
What are the chances I got a dud phone? I want to root and install CM10.1 but I don't even know if it's worth it if I'm going to have WIFI issues and will have to take the phone back anyway.
Anyone run into this?
Does it work on a WiFi that doesn't have a password

Just tried, same issue. As soon as I hit connect it doesn't even bother trying to connect. It immediately says "saved" under the network I tried connecting to, and within moments that network disappears. When it reappears it says 'not in range'.
I think this phone is hosed.

Question Wifi will not stay connected,

I woke up this morning and noticed my wifi will not stay connected, I tried resetting my home network, also choose to forget saved networks, reset all connections, and even did a factory reset. Still wifi will not stay connected. Also tried on different network. I know Pixel 6 had a problem last year but I never experienced this until today. Any Help would be appreciated
Also wanted to say I am running stock firmware for T-Mobile. I did do a security update to see if that would fix wifi but it did not. Have not installed any new apps either.
Figured it out, It was the router after all. I have 1 router and 2 access points., named differently. I left and tried it on open wifi at coffee shop and everything worked. I went back home factory reset my router and put in new ssid and password. Now everything works . I never would have thought it would be router, because laptop and other devices had no problem with connecting.
