After booting from a cd, I cant set anything with network card, I dont see any nearby computers and DHCP is enabled on the network I am using (home network). I have seen indications that the problem may have something to do with the NIC card. In one case I have a laptop with a Linksys Wireless G card, on another machine I have an older Linksys hardwired NIC card. Nothing exotic or out of the mainstream. I dont believe it is a NIC driver problem,unless it is a nonspecific NIC problem. Could it be antivirus software or other security software ? Any ideas??
