I have a Windows XP Professional machine connected to a hub and then a router for my DSL. I have a PCI NIC in currently and everything works fine. I need to switch to a USB NIC to free up a PCI slot. When I try to use the USB NIC I cant see the network. IPCONFIG/RELEASE and IPCONFIG/RENEW don't help. RENEW fails saying it is unable to connect to the DHCP server. RELEASE and RENEW works fine for the PCI card. The link light is lit for the USB NIC and the loopback ping to 127.0.0.0 works fine. I get an IP address of 0.0.0.0 and can't ping any other address. Any advice????
