Getting Arch to see the card

undeadpenguin · 2005-10-23 20:43:52

I just got a Thinkpad R50e and have been trying to get Arch to work with Wifi on it (it uses the ipw2200 driver). I've got the modules all installed and loaded and stuff, but Arch doesn't seem to see the device:

[root@mezzanine zero]# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:0A:E4:39:3F:0E  
          inet addr:192.168.0.104  Bcast:192.168.0.255  Mask:255.255.255.0

          Interrupt:11 Base address:0x7000 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:2 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:100 (100.0 b)  TX bytes:100 (100.0 b)

It's only detecting my ethernet card. I find this really weird because Debian and Slackware both see the wifi as eth1 when I do ipconfig -a and a previous installation of Arch I had on here (yesterday -- I borked it by accident and reinstalled) was able to see it.

How do I get this install to see it?

did you read the wiki?

you can check on your wireless interface with
iwconfig
included in the wireless_tools package

Hmm yeah I had read that. My modules didn't compile right or something, I guess, anyway I reinstalled and now they're working perfectly, I can see eth1 in iwconfig and in ifconfig. I can't seem to connect to my network, though. Could it be because I've got wep enabled?? I tried using the key option, but whenever I try to commit my changes I get something like:

# iwconfig eth1 essid myessid key 0000etc commit
Error for request "Commit changes" (8B00):
SET failed on device eth1 ; Operation not supported.

Am I understanding the documentation on how to do this wrong??

Sorry, I'm not really new to Linux, but I've *very* new to wireless networking...

[edit]
Err... fixed that... Once I added the ap option I can commit it with no problems. However, I still can't connect to the network for some reason. I can't bring the device up...

[edit 2]
Odd... it's working now. Maybe my router was down last night or something, or I typed my wep key in wrong...

#pacman -S ipw2200
To install ipw2200 and other packages.

#nano /etc/rc.conf
To edit your start-up options.

It should look something like this if eth1 if your ipw2200 card ..

lo="lo 127.0.0.1"
eth1="dhcp"
INTERFACES=(lo eth1)

#nano /etc/conf.d/wireless
To edit your wireless settings ..

It should look something like this ...

wlan_eth1="eth1 mode managed essid dexter key D0DB931213"
WLAN_INTERFACES=(eth1)

Then reboot.

A few checks & tests if you have any problems ...

#dmesg
To ensure that the ipw2200 is installed correctly

It should look something like this ...

And hopefully you are up and running!
