[ltp] WiFi on T42 (ifup eth1 no go, txpower is off)

Hello,

I tried turning the 'tx power' on, but got this error:

  # /sbin/iwconfig eth1 txpower auto
  Error for wireless request "Set Tx Power" (8B26) :
      SET failed on device eth1 ; Invalid argument.

Before I did this I restarted the computer, and then Kudzu kicked in,
detected my WiFi card correctly, I told it to use DHCP to get the IP,
but eth1 was not brought up, and I still can't do it manually:

  # ifup eth1

  Determining IP information for eth1... failed.


And now iwconfig say this:

# /sbin/iwconfig eth1
eth1  IEEE 802.11b  ESSID:"WirelessFoo"  Nickname:"ipw2100"
      Mode:Managed  Frequency:2.412GHz  Access Point: 00:09:5B:29:41:3F
      Bit Rate=11Mb/s   Tx-Power:off
      Retry:on   RTS thr:off   Fragment thr:off
      Power Management:off
      Link Quality=100/100  Signal level=-56 dBm
      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:0   Missed beacon:0


Tx-Power is still off, but the AP Mac address is correct, and I noticed
that 'Signal level' changed a few times (-54/-55/-56 dBm), so this WiFi
card _is_ doing something.

Could something external to the card itself be the problem (e.g.
iptables or missing route)?


I feel like a dog on a leash with this ethernet cord stuck into my
'mobile' laptop. :(, so any help with this would be very appreciated.

Thank you,
Otis
