I have a VIAO VGN-NW20SF and have been using a wireless network in the UK without any problems. I have recently moved to Australia and am staying with some friends but cannot connect my Viao to their wireless network. I have no problem connecting other devices so it has to be something to do with the Viao settings. When I check the status of the network it says that the IPv4 connectivity is connected but hte IPv6 has no internet access. I have tried to switch off the firewall but that doesn't help and I have tried to update the driver but that doesn't help. I can connect the computer by plugging in the ethernet cable but not the wireless. Any suggestions greatly appreciated as I am staying here for 3 months so could really use the wireless! Thank you
