I had a WRT54GS v 1.0 router and the accompying PCI card in my daughters computer. I recently purchased a WRT54GS with SpeedBooster v. 2.1 and a new PCI card for her PC. I can not get her PC to even see the router. What I have done: (I have always done these things before) I disable SSID broadcast. Both PC's are in same workgroup. I use WPA (altho now it is WPA2). I use MAC addressing, and hers is allowed. Could the problem possibly be that her card can't do WPA2? I tried to install the drivers that came with the card, but windows keeps saying it can't find a better match than what is already installed. I even un-installed the driver and pci card, yet I get same msg. It does not even let me install the newer drivers from the cd that came with her pci card. It says the ones installed are best match, but the date on them is 1/2004 Any help appreciated.
