My X31 has an Intel PRO/Wireless LAN 2100 3B Mini PCI Adapter built in.
Initially I thought it did not work. I could do:
# iwconfig eth0 essid <name> key <key>
and it seemed to work fine, but no tx power:
# iwconfig
eth0 IEEE 802.11b ESSID:"rightname" Nickname:"ipw2100" Mode:Managed Frequency:2.462 GHz Access Point: 00:0F:34:D5:90:E0 Bit Rate=11 Mb/s Tx-Power:off Retry min limit:7 RTS thr:off Fragment thr:off Encryption key:XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XX Security mode:open Power Management:off Link Quality=100/100 Signal level=-58 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:184 Missed beacon:0
but
# iwconfig eth0 txpower on
Error for wireless request "Set Tx Power" (8B26) : SET failed on device eth0 ; Invalid argument.
Apparently this is not a problem! I can use it and still see TxPower:off so it's just not related.. I'd like to make KWirelessManager aware of this, it still shows it as disabled even though it gives me the correct speed, but as it's working it's not really a problem..
The reason is this ipw2100 bug, fixed in 1.1.5 (I have 1.1.2).
I added eth0 to my /etc/network/interfaces file and ifup'd it manually.
My /etc/acpi/wireless.sh with lots of debugging info
