Well I'm a bit baffled because wireless seems to be working 
Is your router/network named BTHub3-7CWX ?
You and me both!! No, network is "VM132089-2G". Clicking the icon brings up the network manager authentication box but even with the correct password, it just cycles through then returns the same box. I tried deleting all instances and starting again but no joy.
It now shows the correct network but with 'never' alongside it and no amount of deleting/editing will remove the 'never'

EDIT: I just realised - the 'never' refers to '
never been used' not '
never use'.......... Duh!!
EDIT 2: I 'borrowed' a dongle from another machine and that connects up ok and an ethernet cable connection also works so why the onboard card won't connect is a mystery..........
