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
