Problemi ndiswrapper

[Marco Cassol]

Salve a tutti.
Ho un problema con la mia scheda wireless PCMCIA netgear MA521. 
Adotta un chipset rtl8180l supportato solo dal kernel 2.4.X.
Vorrei farla funzionare su Debian con kernel 2.6.8.1 per questo ho
provato con ndiswrapper. Installato il programma e il driver per XP 
NET8180.INF, carico il modulo di ndiswrapper e la lucetta di 
linkaggio della scheda si accende. I problemi sorgono ora.
Appena caricato il modulo ho la situazione:

#tail -f /var/log/messages

Sep  1 19:16:28 localhost kernel: ndiswrapper: driver rtl8180.sys
(Realtek,07/09/2004,5.170.0709.2004) added

Che dovrebbe esser corretta.

poi faccio

#iwconfig wlan0 essid Wireless channel 7

#dhclient wlan0

Ma se pingo il mio gateway dopo aver staccato il cavo della scheda 
di rete ottengo:

# ping -c 3 192.168.0.254
PING 192.168.0.254 (192.168.0.254) 56(84) bytes of data.

--- 192.168.0.254 ping statistics ---
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time

, pipe 3


Vedo che la richiesta di ping è fatta da 192.168.0.3 che è la scheda
di rete scollagata, ma cosa devo fare adesso?

Grazie mille ancora, Marco.
