My Galaxy S2 (ICS I9100G) connects to my home wifi but sometimes does not actually transmit data. I took it to the shop and they did a factory reset (which I could have done on my own) and then was told to take it home and see if it was any better. It wasn't.

O2 tech support didn't really have much to offer so I tried various different online fixes. None worked.

We got another router (for the back of the house) which used WPA2 whereas the initial router uses WPA. My SGS2 works absolutely fine on this new router.

What's going on?

1 Answer 1


My solution was to change the front room wifi to WPA2 to match the backroom's wifi (WPA2) which I never had a problem with.

Don't know why this works I cannot believe the SGS2 has less than optimum support for WPA. Maybe it was buggy software ... although I am fully updated and have been since I got the phone. (September 11)

I should mention this was not a problem caused by ICS or fixed by the firmware upgrade as I had the problem pretty much as soon as I got the phone (September 11).
