I had to do a clean install of windows.All of my drivers and software reinstalled without a problem,EXCEPT the Ethernet connection/adapter.I went under device manager and uninstalled it as well as trying to update it.It will not update because I cant get on the net.I have a 4550 with XP Pro.My Dell CD says I have Pro10/100 LOM.I tried to manually install each of the drivers on the Disk but no luck.My computer was fine last night!I usually do a clean install about every 4 months.[Due to having kids on it!]Si I have really never had a problem before.I went to the Dell sight on my Laptop to try to get the driver to back it up to another disk for installation but no luck.My warranty ran out last month so Dell wont help.Any Suggestions????>
