Description Mark J. Bobak 2005-09-14 22:19:50 UTC

I'm using a Dell Inspiron XPS Gen II laptop, which implements the 2915 chipset.
I have a recent (less than a week old) Gentoo 2005.1 built from stage1, using
the gentoo-sources 2.6.12-gentoo-r10 kernel.

I had no problem emerging the ipw2200 ebuild.

When I reboot the system, the ipw2200 module loads correctly, and I can verify
it via lsmod.  But, iwconfig eth0 says "no wireless extensions", and ifconfig
eth0 reports "Device not found".

Now, the workaround is simple.  If I do:
rmmod ipw2200 && modprobe ipw2200

The problem is solved.  Not only does the card become available, all my info,
IP, netmask, broadcast, etc, set in /etc/conf.d/net is set correctly, even 
though I don't re-run any startup scripts.

So, I'm stumped.  The module loads on boot, but doesn't work.  Unloading and
reloading solves the problem.

I suppose I can hack one of the /etc/init.d scripts to explicitly do the
rmmod/modprobe, but that's not a nice solution, and it's certainly not 
"the Gentoo way...".

Help!

Thanks,

-Mark

Reproducible: Always
Steps to Reproduce:
1. reboot system, wireless module is loaded, card does not work.
2.rmmod/modprobe solves the problem.

Actual Results:  
After reboot wireless connection does not work.

Expected Results:  
I should work.

What does a plain call to `iwlist` and `ifconfig -a` yield upon boot-up 
(before your manual fix)?

Comment 2 Mark J. Bobak 2005-10-06 20:57:10 UTC

'iwlist' gives a usage error:
mars mjb # iwlist
Usage: iwlist [interface] scanning
              [interface] frequency
              [interface] channel
              [interface] bitrate
              [interface] rate
              [interface] encryption
              [interface] key
              [interface] power

              [interface] accesspoints
              [interface] peers
              [interface] event

I'm not sure which of the iwlist options you want me to demonstrate....

Here's iwconfig output:
mars mjb # iwconfig eth0
eth0      unassociated  ESSID:off/any
          Mode:Managed  Channel=0  Access Point: 00:00:00:00:00:00
          Bit Rate=0 kb/s   Tx-Power=20 dBm
          Retry limit:7   RTS thr:off   Fragment thr:off

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

So, clearly, it's not associating with the AP.  But why does unloading and
reloading fix it?

Here's ifconfig -a output:

          mars mjb # ifconfig -a
          eth0      Link encap:Ethernet  HWaddr 00:13:CE:1A:82:66

          RX packets:60 errors:0 dropped:0 overruns:0 frame:0


Finally, here's the same output after a simple rmmod ipw2200 && modprobe ipw2200:

Please see if you can reproduce this using net-wireless/ipw2200-1.0.7-r1.
