I'm using a WRT54GS with a WPC54GS (PCMCIA). When i want to transfert files from one computer to another the connexion break... It work perfectly when i go on Internet or if i browse files. I'm using, WPA, Mac filtering, and my SSID is hidden. I am on XP pro. I'm using the liksys software to establish the connexion. Do you know what i have to change to make file trasfering correcly ? Thank you.
