IS there a knack to hooking up to the Telecom free WiFi network? I have a SGSII and I've been trying to unsuccessfully connect to a phone box WiFi downtown. Phone says signal is strong (I'm about 5 meters way) wizzes away saying" obtaining IP address" and then gives up and says" unable to connect" and that's it. What could I be doing wrong? I never normally have any issues connecting to WiFi.
