Network device name changed-fedora4..network in mess..

[Saurabh Siddharth]

Hi..
I installed fedora4 this tuesday on my dell latitude d600...i configured 
for wireless( i have intell 2100) and it was up and running. but once i 
rebooted my machine, it did not work. i opened the network 
configuration(system-config-network) and under the hardware tab i saw 
that the system had swapped my device names( it was now eth0 for 
wireless and eth1 for ethernet) Other things remained same. Under the 
devices tab it would still show eth0 as ethernet and eth1 as wireless. 
so when i was trying to activate the wireless, i got an error message 
saying check cable. to fix the problem i changed the names under 
hardware tab. but it didnt get fixed. i played around a bit more with 
these names, but no solution. now my network configuration is in a mess. 
i can use neither ethernet nor wireless. can i reset things back to 
default without having to reinstall fedora ( i have already done a lot 
of customisation).. please tell me what additional information do i need 
to provide to get help. i am new to linux so you will have to tell me 
the exact command that i need to execute to get the information...plz help
thanks
