I read your exchanges with interest ... I too have an iPhone but cannot connect to the internet via my Orange Livebox. However, I have been able to connect elsewhere. My problem is slightly different, in that, the iPhone shows that I have a connection, but when I attempt to go to a web address I get an error like this
POSIX error 12 - cannot allocate memory
NSPOSIXerrorDomain:12
Also when I check my WiFi settings I notice that in the url field it says 'renew lease'
I have tried all of you previous suggestions, pairing etc, but the problem is still the same ... many thanks
Mike
