Please kindly help my uncle out !

My uncle has two computers (Computer 1 and Computer 2)at Home. Both Pcs are running Windows 98 SE. Tthose 2 PCs are connected to a Linksys 4 port router and has connection to the Internet. Everything was fine until recently after he upgraded his hard drives on both PCS from a local computer shop and bring both PCs home. Of course, he hooked everything up. Computer 1 is fine but the Computer 2 cannot has any connection to the Internet. (The network settings is exactly the same as Computer 1). Now he cannot even access his Linksys setup menu at http://192.168.1.1. So I even suggest him go to Windows Dos and type winipcfg and he cannot getting anywhere and cannot renew / release his ip. He even removed the network card from the Device Manager in Control Panel and add the network card and TCP/Ip back, still has no luck.
Since he mainly use Computer 1 for his home-based business, therefore, any suggestion to solve his problem will be highly appreciated in advance.
FYI, his currently settings is as follows:
Obtain Ip automatically
WINS --> does not use WINS (does not choose DHCP)
Gateway is 192.168.1.1
DNS: 24.69.255.196, 24.69.255.213
Please help ! !!

What do the LEDs on the network adapter and router show? A cable that isn’t plugged all-the-way-in? Larry

Hi Larry,
Thanks for your prompt reply and the Router and NCI LED light are ON. Cable is plug in all the way.
I forgot to mention on Computer 2's D drive partition, there is a Chinese Windows 98 Se and use the same network setting and it can connect to the Linksys Router and the Internet fine. (Suing the same NIC)
So that means at least is not the connection / NIC hardware problem then ! But I still cannot figure out why it does not work in english Windows 98 Se in Drive C on Computer 2.
Please advise.

Are you sure the router is at 192.168.1.1 and not 192.168.0.1? If a dial-up adapter is installed, try removing and reinstalling it. Yes, I know you are not using it, but it might fix a TCP stack problem. See http://duxcw.com/faq/network/winsock.htm for other steps. Larry
