Just bought the new DTEK60, real nice phone, cannot connect to my wifi, error message is "authentication problem", have tried all the usual things, turn airplane mode off/on, turn mobile hotspot on/off, turn my router off/on, modify network, forget network, static selection, restart phone etc etc. any extra advice would be much appreciated so i can start using the phone (PS, is a sim card required for wifi to connect, i wouldn't have thought so)
cheers all
