I have my sisters computer at my house was going to download some updates and a couple of other useful programs using my cable isp , she does not have internet right now, I plugged wire into ethernet slot but I cant get online . Keeps saying cannot find server. I went back thru the set up for it all and everything seems set up fine. my comp works fine. also she had dsl at her house and it would not connect to it either but no problems with a laptop . could ethernet card be bad ? I am also running a router . the computer is a compaq presario win xp home athlon xp 2600 , the cable modem and router are both lynksys any ideas ?
