Having issues connecting my Vista laptop w/ my PPC 6700 that has WMWifiRouter 1.03.. I have been able to connect my XP laptop to the WMWifiRouter successfully w/ no problems, and then connect the Vista laptop next to my WMWifiRouter successfully (Weird).. But for some strange reason the Vista laptop will not connect to my WMWifiRouter by itself (Windows cannot connect to "WMWifiRouter", then I select "Diagnose the problem".. then it states "Wireless association failed due to an unknown reason", & I have the option to "try connecting to "WMWifiRouter" again, & it just loops in error..) I have to first connect an XP machine, then my Vista machine for it to connect & pick up an IP address.. Any thoughts why Vista doesn't pick up an IP address & connect w/ WMWifiRouter by itself?.. I have re-imaged my Vista laptop down to the bare minimums, & re-flashed my PPC6700 w/ the bare minimum.. Any suggestions?.. I even changed the default ad-hoc connection name on my PPC 6700 to something specific, left it open & WEP secured w/ no success, same issue occurs..
