Intel Pro Wireless 2200 Wifi Question

[scojo]

I occasionally have trouble connecting to my wifi network at home.

Here are some details:
5.9 Standard GOLD built on Dec-16-07
Intel Pro Wireless 2200 wireless networking card

From /etc/modprobe.conf

Code:

alias eth0 8139too
alias eth1 ipw2200

From /etc/ifplugd/ifplugd.conf

Code:

INTERFACES="eth0 eth1"
ARGS="-fwI -u1 -d5 -pql"

As root I try to connect from the command line using this:

Code:

iwconfig eth1 essid foo key s:xxxxxx

and occasionally I get this:

Code:

Error for wireless request "Set ESSID"
(8B1A):  SET failed on device eth1; invalid argument

This doesn't happen all the time, but when it does, I typically reboot a couple of times and I'm able to connect using the iwconfig command above.

Anybody have any idea why this happens?

Thanks,
scojo
