configure a wireless card
 

HI, I installed my d-link G650+ card on a mandriva with madwifi. Everything went fine, the card is recognized and I can see this when I type ifconfig:
ath0 Lien encap:Ethernet HWaddr 00:0F:3D:AF:B7:80
adr inet6: fe80::20f:3dff:feaf:b780/64 Scope:Lien
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:6 dropped:0 overruns:0 frame:6
TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 lg file transmission:200
RX bytes:0 (0.0 b) TX bytes:140 (140.0 b)
Interruption:5 Mémoire:e0d00000-e0d10000

this when I type iwconfig:

ath0 IEEE 802.11g ESSID:"WifiSerge"
Mode:Managed Frequency:2.462 GHz Access Point: 00:13:10:3F:E9:FA
Bit Rate:36 Mb/s Tx-Power:18 dBm Sensitivity=0/3

Power Management: off
Link Quality=13/94 Signal level=-82 dBm Noise level=-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

so the card works well. Problem is no matter what I do, i can't get an ip adress for this card. I typed ifconfig ath0 up, iwconfig ath0 essid ESSID, nothing works. I can't get this IP. What would be the problem?

I'm new to all this myself but have you tried

dhcpcd ath0

I had to install the rpm package (I'm using Mandrake 10.1) to do this but when I did and then ran ifconfig I managed to get an ipaddress from my dhcp server.

Now ... if only I could ping my router ;)

My dchp deamon works fine with my eth0 device so i should work with ath0 too!
