Hi! I'm using WRT54G V3.1 with FW 4.20.8de with my notebook with Windows XPpro SP2. I tried to use WPA-PSK but there I can only get a connection for a few seconds and then the connection is lost. With WEP128 I get a connection but it's not possible to send or to send IP-traffic. The only working method is to use WEP64 but I want more security. I have SSID-broadcasting disabled. In future I would like to use WPA-PSK oder WPA2-PSK. j.
