I have been using my dorms WiFi forever -- but since the latest system update on my S3, it won't get internet even though im connected to the WiFi (status says I'm connected -- but the icons in the notification areas stay white). Its like that all over campus. Other places I can use the WiFi without any problems.

Immediately after the mentioned update, internet worked for one more day on my phone in my dorm, but after that only other WiFi networks seem to work for me.

I have no idea what the reason could be. Any ideas what I should look for?

    Maybe you could give a few more details? You write "after the update". Did anybody update the internet? Or the dorm routers? Or did you update "something" on your S3 (and if so, what)? How do you know you are connected, if you aren't able to use the net -- does anything work (e.g. browser, or some apps, or the sync)? What color does your wifi icon in the statusbar have when you are connected a) in the dorm, and b) to "other wifi signals"?

  • OK, the white symbols in fact indicate you have no connection to the Google servers (otherwise symbols would be blue), though you really seem to be connected. You could check the logcat for error messages when connecting, which would help analyzing the problem. You could also try removing and re-adding the dorm wifi. A very last ressort would be a factory-reset -- but I'd leave that until it really presses you (as it would delete all your apps and data on the S3, so you can already check for a good backup, never hurts ;)

  • I just updated your question to reflect these facts (makes it easier to find them). Could you please also add the Android version before and after the update? Maybe that gives some clue to somebody also having a S3. Did you try removing and re-adding the campus network on your S3? Maybe something got messed up with its configuration (e.g. the DHCP settings for default route or network mask).

Have you tried dialing *#*#526#*#* ?

It fixed a wifi connection problem I had.

I dialed it on the phone, got the "call cannot be completed" message. Hung up, restarted the phone, then went through the whole phone call again.

It worked. My wifi problem is fixed. I kid you not. Google it. I hope this helps.

Have had the same issue on my droid 2.3.6. It used to connect to wifi but could not browse the internet until I disabled:

Parental Control

from my wifi router.

Hope this will help someone.
