I just installed Fedora Core 5 prior to updating my kernel my wireless card was not found now. I upgraded kernel's and it is found, it takes the device ID of eth1 when it should be wlan0. When I try to activate it, it says
when I run iwlist eth1 scan

I am not sure how to fix this problem. any suggestions?

Two choices that might be possible one is to edit the /etc/modrobe.conf file and change the alias line entry for your wireless interface from 'alias eth1 mydevice' to 'alias wlan0 mydevice'.

The other is to rename your /etc/sysconfig/network-scripts ifcfg-wlan0 to ifcfg-eth1 and then edit the file and change the line DEVICE=wlan0 to DEVICE=eth1

Then restart the network service; service network restart

All as root of course.

Ok so now everything has correct name and it seems to have correct drivers since it does have the right name... when i try to connect it still comes up with
Determining IP information for wlan0... failed; no link present. Check cable?

And which wireles card are you speaking about? How are you attepmting to activate the interface?

I go into the network dialog then I select the broadcomm device (which is now wlan0 instead of eth1) I click on the activate button and it will try to connect but fails and suggests checking the cable. This is a wireless device and it should be trying to connect to my wireless router with DHCP. And still i try to do the iwlist wlan0 scan and it still gives me errors. I read a article that suggested recompiling the kernel without the bcm43xx then use ndiswrapper and make it work. I just want to know the easiest and fastest way to get this to work.

Ok i got it working now using the bcm43xx-fwcutter
