Can anyone provide any suggestions / information? Surely this must be a known windows 7 issue...?
In your router, is the advanced wireless section set to only allow certain mac addresses? If so, add your computer's mac address to the list.
Another thing I've seen a few times is that the wireless card under Windows 7 doesn't have a mac address at all in the settings.
You can check this by entering ipconfig /all in the command prompt.
If it shows all zeros for mac address you can add it manualy in the wireless card's settings in the device manager.
