Curious ipw2100 issue (wireless networking)
On my laptop (a thinkpad X40), I have the ipw2100 wireless card. I installed the drivers from, and everything was fine. Then one day, it just magically stopped working for no apparent reason.

It is detected as a wireless device OK:

stevex40 steve # iwconfig eth1
eth1      unassociated  ESSID:"<my wireless access point>"  Nickname:"stevex40"
          Mode:Managed  Channel=0  Access Point: 00:00:00:00:00:00 
          Bit Rate=0 kb/s  Tx-Power:off 
          Retry:on  RTS thr:off  Fragment thr:off
          Encryption key:XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XX  Security mode:open
          Power Management:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0  Missed beacon:0

It can even see my gateway ok:

stevex40 steve # iwlist eth1 scan

It just refuses to associate, despite the fact that I am sitting less than 50 centimetres from the wireless access point. As far as I can tell, I am doing everything right, and there is no hardware problem - just a configuration problem.

I really, really must have wireless working. I hate being tied down by cat-5 :(


Edit: Other people are still able to access my wireless access point, and I am definately using the correct key.

I've discovered the solution to my problem. I was (for some reason) loading the modules in the wrong order. It works now. Whoops.

This is an update to this thread, a LQ member asked me which order I loaded the modules in:

This is the order that I load my modules in (from




e1000 and subfs are my other network card and an automounting filesystem. I guess this problem has something to do with the fact that ipw2100 depends on those iee80211 modules, and doesn't use them if they are loaded in the incorrect order.

I hope this helps someone who stumbles in from google.
