Ciao.
Sto provando ad usare il driver perchè ho una Netgear MA521.
Dopo averlo compilato li ho aggiunti a modules.preload (sto usando Mandriva 
2005LE) in questo ordine:
ieee80211_crypt-r8180.ko
ieee80211_crypt_wep-r8180.ko
ieee80211-r8180.ko
r8180.ko

All'inserimento dmesg la vede :
ieee80211_crypt: registered algorithm 'NULL'
ieee80211-r8180: loading with WEP enabled.

wlan0: no IPv6 routers present

Penso che tutto vada bene, ma quando provo a dare ifconfig wlan0 up non riesco 
a connettermi con il router. Questo sia che usi il DCHP sia un IP statico.

Provando il DHCP :
[root@localhost ~]# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:09:5B:BF:FB:62
          inet6 addr: fe80::209:5bff:febf:fb62/64 Scope:Link

          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

[root@localhost ~]# iwlist wlan0 scanning
wlan0     No scan results
Perchè non vede la mia rete wireless ?
Tanto per precisare, se imposto mode master, vede la rete, ma a me serve 
Managed.

Nel file  /var/log/messages ho :
Sep 23 19:18:04 localhost dhclient: DHCPDISCOVER on wlan0 to 255.255.255.255 
port 67 interval 4

port 67 interval 9
Sep 23 19:19:05 localhost dhclient: No DHCPOFFERS received.

Allora provo a dare un IP statico:
[root@localhost ~]# ifconfig wlan0 192.168.0.10
[root@localhost ~]# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:09:5B:BF:FB:62
          inet addr:192.168.0.10  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::209:5bff:febf:fb62/64 Scope:Link
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Interrupt:19 Memory:e90c6000-e90c6100
[root@localhost ~]# ifup wlan0

Determining IP information for wlan0... failed.
Che faccio?
Ma il modo Auto come funziona? E' proprio auto in tutti i settaggi della 
frequenza del canale, velocità etc?
Allora provo impostando mode Managed

[root@localhost ~]# iwconfig wlan0 mode Managed
[root@localhost ~]# iwconfig wlan0

wlan0     IEEE 802.11b  Mode:Managed  Frequency:2.417 GHz
          Access Point: 00:00:00:00:00:00   Bit Rate=11 Mb/s
          Retry:on   Fragment thr:off
          Encryption key:off
          Link Quality=49/100  Signal level=-103 dBm  Noise level=-205 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Perchè Access-Point è tutto 0?
[root@localhost ~]# iwconfig wlan0 essid "Wireless"
[root@localhost ~]# iwconfig wlan0 channel 5
Error for wireless request "Set Frequency" (8B04) :
    SET failed on device wlan0 ; Operation not permitted.
Perchè non permitted?

Qui mi fermo perchè mi sembra che basti no? ;-)
Help, Aiuto. !
