Check /etc/sysconfig/network-scripts/ifcfg-eth1 for:
HWADDR=

If not set, set it.  If set incorrectly, set it correctly.

Not set at all. I set the value. I hope this fixes the problem.

Also check your firmware version:

# ls -l /lib/firmware
...
-rw-r--r-- 1 root root 191142 Mar  7  2006 ipw2200-bss.fw
-rw-r--r-- 1 root root 185660 Mar  7  2006 ipw2200-ibss.fw
-rw-r--r-- 1 root root 187836 Mar  7  2006 ipw2200-sniffer.fw
...

Symptoms are exactly as you describe.  Workaround is to:

# ifdown eth1
# rmmod ipw220
# modprobe ipw2200
# ifup eth1

That should work every time, but indicates that the firmware may be bad,
or HWADDR is wrong in the ifcfg-eth1 file.

Good luck!
