I have 2 computers I'd like to be able to access files between the 2 and also share internet access. I have a comcast cable connection. To do this, I have a Linksys 4-port cable router and 2 linksys 10/100 nic cards. I am able to see each computer in the network, but one of the pc's seems to freeze a lot whenever anything is done network-related...internet, file transfer, etc. This happens consistently when i try to transfer large files from one pc to the other. Small files seem to transfer with no problem. I am using tcp/ip. Should i be? Or should i be using Netbui? I am no network expert, so i have no idea. Any ideas?
