I don't read Russian but I assume this problem has to do with what I'm facing: I can't make my USB stick (based on Ralink rt2571w chipset) associate with my Asus WL500g deluxe (Oleg's firmware 7f) under linux.

Doing a iwlist scan wlan0 gives this:

The neelix access point is the Asus, the testing AP is the D-Link. The WEP-104 group cipher is what is puzzling me... How can I force this into TKIP and force the Asus to be either WPA1 or WPA2 but not both? I found already this thread but it doesn't work for me, the router keeps saying it does both with WEP-104...
