<<< when I try to view available networks I am informed there are no networks in range and yet my wifes computer see's both the Voyager and the Linksys and can connect to either, >>>
I don't follow this. I thought the router was a "Voyager" and the wireless adapters were "Linksys"
If this is correct, and your wife is actually connecting directly to your network adapter, yours must be configured to run in "Ad Hoc" mode. In the Network Connections folder, right click the Wireless Network Connection and select Properties. Click the Wireless Networks tab and then click the Advanced button. Set it to "Access point (infrastructure) networks only". Should you be running the Linksys software, there should still be an option to use Infrastructure networks or, better still, change from the Linksys software to Windows' own wireless networking.
