Been running unsecured on my WRT54GS. Got crazy neighbors now so decided to change to secured settings. I RESET the router. Started over with CD wizard. Set up my desk top (XP) first, with WPA Personal settings. Setup successful! Tried to set up two laptops on the the established network. One is XP one is VISTA Home Premium. New network is functional on these machines, but only as an UNSECURED network. Why?? I changed all settings to match the router settings, and I get a message that the settings conflict with the router--but they are exactly the same. My laptops are still unsecured. What am I doing wrong?
