I've just bought my first Samsung Galaxy S2 and love it to bits. The only problem I've encountered in the three days I've had it is that it won't connect via wifi to my home computer (a Mac).
With my Mac's 'Airport' and 'Internet Sharing' turned on, my boyfriend can connect to wifi from the Mac to his iPhone but my S2 refuses to connect. Once I turn on wifi on the S2, under 'Wi-Fi networks' it brings up my computer and my neighbours' wifi networks. I click on my computer's name, type in the password, but then it just cycles from 'Scanning...', 'Connecting..' to 'Disconnected'.
I've spent hours trawling Google for a solution. Under the 'Advanced' wifi settings I selected 'Use static IP' (but I'm not convinced I put in the right numbers under 'IP address', 'Gateway', 'Netmask' and 'DNS'). I don't know if it makes a difference but in System Preferences > Network > Airport, it says 'Airport has a self-assigned IP address and may not be able to connect to the Internet'. But my computer is clearly visible on the wifi network because my boyfriend could connect wifi from my computer to his iPhone.
After disconnecting from wifi, on the S2 I tried dialing *#*#526#*#* and it came up with 'Wlan Test Engineering Mode Status... TestMode Driver loaded [OK]'. But then turning wifi back on and trying to connect to my computer, it still cycles through 'Scanning...', 'Connecting...', 'Disconnected'. So frustrating!
I haven't tried resetting factory settings because the phone is literally three days new out of the box.
Appreciate any advice!
