We have just got a DELL Latitude 610 laptop and have installed FC4. Everything has gone well (minor glitch with screen flicker resolved by screen resolution) apart from the Wireless card (Intel 2200BG). The card and AP have been configured (the AP talks to an XP PC (just washing my mouth out) ok, so we know the AP is configured ok) - but we get no communication between the laptop and the AP (we have tried both static and DHCP).
We do not get any errors per se - just that there's no communication. The laptop has an ethernet connection that has been sucessfully linked to the AP.

Any ideas as to how we can trouble shoot this?

Should the wireless card 'work out of the box' or is there additional software you need to download to get wireless to work under Linux?

hi SteveT, i'm new to this site and cannot post url's till i've had more posts. (nice feature btw) anywho i googled intel 2200bg linux and came up with a site @ sourceforge that might be some relevance to you, check it out.

We have now upgraded the FC kernel to 2.6.15 and downloaded the 2.4 version of the IPW firmware to /lib/firmware.
Everything boots ok but the eth1 (wireless device) does not come up
- the MAC address for the device seems permanently stuck on 00:00:00..... even after a probe.

When trying to activate the card manually from the GUI (Desktop-System Settings - Network) we get the following errors:

Cannot change name of lo to eth1: Device or resource busy
cannor parse MAC 'lo eth1' at argument 2
interface 'dev16587' not found

.....
The above error repeats for different dev numbers

We can turn the RF on and off via the hardware switch (DELL 610 - Fn & F2) - and that does affect the /sys/bus/pci/drivers/ipw2200/*/rf_kill file (toggles 0/2) - but still no joy.

When booting we get a message that the MAC address on the wireless card is not as expected.

Dmesg gives:
