It is a wired connection to the router – the cable must be unplugged and replug every computer startup?
I have Wireless G Motorola router connected to computer by Cat5E cable running XP. When I start computer, I must unplug either end of the CAT 5 cable and replug it before the network connects. It has worked for several years until I got a new motherboard. I have tried resetting everything, flashed the latest firmware. I am at wits end.
i am not a networking genius, but try the simple things first. swap ethernet cables. Is the network on the motherboard or on a card? If it is hard-wired disable it and try adding a separate network card.
