I just recieved a new old IBM Thinkpad (i Series 1161-52U), and there is an Ethernet port at the back. Now, it runs Windows 2000, which I am less familiar with, but I used the wizard to have it connect to the internet VIA LAN. Now, I try it, and it's not connected at all. It's not shown in the network on my other computers, and the router hasn't acknowledged it yet. I went into Device Manager, and nothing is missing drivers. Please help!
