just bought a GS2 I love the phone, but the wi-fi is terrible, pretty much non existent. However I'm not too sure exactly what the problem is
My home wi-fi is Virgin Media via a D-link router into the Virgin Modem (not the superhub, had too many problems with it) P.C's on the network connect fine, as does my SanFrancisco & ipod touch.
I have the modem/router in the livingroom but even if I sit in the same room (less than a metre away) the SGS2 has problems connecting & holding the connection.
It seems to be constantly searching & even lists other networks on my street fine. But Sometimes after I enter the password it says "remembered not in range" or connects for a few seconds then cuts out, barely long enough to connect to a webpage or the appstore.
I read that sometimes this phone can have problems connecting to networks with TKIP so have changed my router to AES only, I also installed WIFI Fixer, both seemed to have a temporarily improvement , but it's soon back to poor performance again.
I really don't know if this is a problem with Virgin Media, D-link routers or if I should return the phone? any thoughts on this greatly appreciated.
I installed MCR GR5 out of the box,
