I had a three station XP network with a NAS attached that worked fine. I replaced one slow PC with a new Vista PC. The Vista PC can connect to the Internet via the Linksys SRX200 with a USB Linksys wireless adapter but the Vista PC does not see the other PCs. In fact, I cannot ping the Vista from the XP PCs and vice versa.
I have tried turning on all all sharing and have even turned off the firewall on the Vista.
Does anyone have any ideas?
