[GT-I9300] Wifi Connected - No Internet issue (Solved!)

Hi All,

After recently updating to stock Jellybean 4.1.1 I started having an issue with my wifi where it would appear as connected to the AP but not able to access the internet. This was intermitting. Every now and again it would work for a bit and then stop.
It appears to be a common problem on this device.

I managed to solve mine by doing a hard factory reset a couple of times... The steps I followed : (Obviously backup all your stuff first).

1. Factory Reset through the settings menu (Erase Everything)
2. Cache Wipe (Hold down vol-down+home+ power) and select wipe cache
3. Factory reset through boot menu (same menu as 2.)
4. Restart device
5. Final factory reset through settings menu again.

I have ready somewhere that the JB update left some of the files on the device in a bit of a nasty state, so multiple factory resets puts things back to how it should be.

Thanks.
