Jeg endte op med en Asus WL-167g USB wlan adapter. Der er både Linux
driver med adapteren og den findes også med min linux (Fedora Core 9).

Enheden bruger rt73usb driveren og den finder enheden helt uden
problemer. Men her stopper legen desværre også.

Mit system er en Fedora Core 9

Her er resultatet når jeg tilslutter usb wlan adapteren:

Som test giver:

iwconfig wlan0

          RX bytes:58 (58.0 b)  TX bytes:4472 (4.3 KiB)

Hvis jeg sætter interface wlan0 op manuelt med en ip
adressen/netmask/broadcast sker der ikke noget (ingen forbindelse)

DHCP giver heller ingen resultat.
Check på den trådløse router viser ikke MAC adressen associeret til det
trådløse netværk (så jeg formoder at der ikke er opnået forbindelse
imellem routeren og usb wlan enheden)

Hvad jeg studser lidt over er linierne i dmesg:

wlan0: RX AssocResp from 00:11:6b:30:82:77 (capab=0x401 status=0 aid=2)
wlan0: invalid aid value 2; bits 15:14 not set
wlan0: associated
wlan0: disassociate(reason=3)

Nogen ideer om hvordan jeg kan komme videre med dette?

(jeg har en windows baseret bærbar som forbinder uden problemer til det
trådløse netværk).

Mvh
