WPA from WEP

And by the way, she's not using wireless. There ain't no way she's using wireless with that old router or that new switch. So discussions of WPA versus WEP aren't relevent here.

I missed where she said she was using Ethernet.

I thought we were talking about a wireless...My bad....

The trouble shooting is a bit different as there is no security to deal with.

I very much doubt that lime wire did anything to stall a Ethernet connection. very unlikely indeed.

The switch she bought is for work groupings, and not for home networks, so that needs to go. What she is likely using, is a older lynksys router that she needs to put back into service. On reboot, the router and computers should reconfig themselves and if not, there is a cable or hardware issue that can be identified with some simple switching of cables.
