Hi Abdrx!
I can't recommend to use WEP-encryption, because it's not secure anymore. But it is possible, that your WLAN-Card (more precisely the driver of your card) does not support WPA-encryption (check this, perhaps a new driver version will help). I had the same problem and bought me a new miniPCI-card...
In general you should change your wireless connection-settings with a wired connection. If your wlan-card supports WPA, on the Asus "Wireless-Interface"-page you type in a SSID, select WPA-PSK, TKIP and generate a WPA Pre-Shared key. Remember all the rules for generating passwords (not to short, no words that stands in any dictionary, no dates, use upper and lower case, numbers and special charakters - there are generators who can do that, too). What OS do you use? I guess Windows. Here you set "Use Windows to configurate.." (I have no english Windows, so I can't tell you the exact name) and an the properties of preferred networks-box you type in the exact same configuration. That should work. If you don't have WPA encryption on your notebook there's nothing else for it but to use WEP/buy a new card... If you want to use WEP, the way is the same.
In general the trick would be to use the wired connection to the box and don't forget to restart the box after you changed anything. And use dhcp on client-side.
Ciao Marc
