Hi

After a week of struggling at home, I'm at the end of my tether trying
to get my work laptop to connect via wireless under FC3. Sadly, it
worked first time under Windows XP which isn't my prefered OS ;-(

The laptop is a Dell Latitude D600 running Fedora Core 3 and the
ipw2200 driver. I've tried both compilation from source and RPMs. I'm
currently using RPMs

The key appears to change

I can't find crc32.ko but arc4 gets loaded OK

Any ideas?

Thanks

Cheers
Peter

$ uname -a

The problem may be that he encrypted key gets changed but not sure

Is interesting that, when you issued the 'ifup eth1' you got an error
about setting the bitrate, maybe your configuration file for eth1 is
re-setting some parameters, one of which is the encryption key.

I'll start to check the config file for your card, then, when the key is
the correct one, just manually assign an IP to the card and see if you can
connect with the AP.

The message seems pretty explicit. The rate isn't understood.
ifup-wireless seems to pass RATE to iwconfig
and iwconfig seems to only understand arguments like 11M, auto etc.
So perhaps change RATE to 11M (to be safe) and then 54M if that works.
Check the manual for iwconfig ...

What type of encryption do you use?

I would try to bring up the wireless manually first, e.g. for WEP

iwconfig eth1 essid montan key your_wep_key enc on rate 54Mbps
(w.o. slash, that's probably wrong in your ifcfg-eth1)

ifconfig eth1 up
dhcpcd eth1

If you use WPA you need a wpa client, don't know if the iwp2200
can use wpa_supplicant.
