The Belkin network setup wizard seeks to gather all the required information to enter into your router's configuration settings for you.
It can't do everything unfortunately.
We'll need to have as much information as possible, as there are a few variables and layers involved in networking. Please post as much as possible, even if you're not sure what they mean.
Tell us what definitely works and how you know this ~ e.g. how her PC is connected to the network.
If you have setup MAC address filtering in the router (after the wizard is completed and by typing in 192.168.2.1 into your browser's address field),
have you entered the Belkin wireless network card's MAC address which has been installed in her PC rather just the MAC address of her PC?
