Hi,As the ralink suport isn't finished with PPC, I've just found a D- link DWL122 (Prism2 USB)
With r213 & r216 the driver seems unstable : - lot of spinning beach Balls- an incredible number of BSSID and SSID perpetually increasing when scanning, especially ghost ones :
ex : for SSID "NETGEAR", it will find : "BEGEAR", "NETGEAT" etc...Same thing for the BSSID : "F5:56:E3:23" will also became "F5:56:E3:23" or "F5:56:E3:2A"
After only 5min of scanning, the list of AP increase to 250 or more, but there is only 10 AP in my neighbourhood.
Everything is running smoothly with the lastest public instal (without Ralink suport) on the Kismac website.
Hope that will help. Sincerely.
