Hello all, it's been awhile since I've posted here. Anyway... My problem is after installing a wired router, one computer goes online (like it should), and the other won't or can't. I think it is related to the aftermarket ethernet card on the older computer. Specs: Upstairs computer, which works fine; Gateway PIV 2g, WinXP, 60g hd, 1g RAM. Downstairs computer, the one that is ornery; Gateway PII 400mhz, Win98, 10g hd, 64m RAM. I have DSL from SBC. I bought a Linksys Etherfast Cable/DSL router, model BEFSR41, with 4 port switch. This plugged into the PIV no problems, it already had an ethernet plug. I ran a 50 foot catv5 cable downstairs to the older computer. I had to install a Linksys Etherfast PCI Adapter card, model LNE100TX, in the older comp to plug into. The installation seemed to go fine, and I ran the installation CDROM and that seemed to work fine also. When the cable is plugged into the card, the two lights on the card light up. On the router upstairs, all the lights are green for power, internet access, and the two cables running to the computers. The downstairs comp keeps trying to use dial up. I unplugged the phone line from the back of the comp, so obviously it doesn't work. Two screens keep coming up -- "Can't dial a connection" (when sometimes it still tries to dial) or "Internet access not found" (or something similar). I re-ran the install disk for the ethernet card a couple times, and ran the install disk for the router on the downstairs computer a couple times. I have checked "Never dial a connection" on some screen that came up, and have checked "automatically detect connections", and also tried finding connection manually. Also, I manually looked for "new hardware", and the comp says the card is there and recognizes it. I really think the problem is getting the downstairs computer to use the ethernet card. I tried all sorts of different things, with all sorts of different screens that came up, so I am a little confused and I am sure I am mixing up some of the info I am presenting here. Ideas? And thanks in advance for the help.
