I have a PC(OS=XP) wired to a linksys router/gateway(WAG54GS),works well,I have added a notebook wireless (OS=Vista). Notebook works well, connects to internet but PC and notebook cant "see" each other,therefore cant share files. I have added IP addresses to "trusted sites" on respective machines and made sure the "discover other computers" is enabled on Vista notebook. They can both 'ping' each other, but only the router is shown on the network on both machines,Windows firewall Off on both. where am I going wrong.
