Its a laptop with built in wireless, only software to use is the windows stuff.
Where is the auto option. I have selected to remember the network, and to autoconnect even if it isn't broadcasting its SSID.
I have removed all wifi security before I left, and he has sent me an email this evening so it looks like it might be working ok now. This isn't ideal, and i cant find mac filtering in the routers settings to secure it that way either.
