I previously had 2 PCs and a laptop from work. I set up the better computer as a host (running XP and with a cable modem direct into the host PC) on a local network and connected the older PC via a crossover cable. If I wanted to use my work laptop, I just unplugged the crossover from the old PC and plugged into my laptop.
As I was getting this new PC, I got rid of the oldest one and wanted to move the previous host down the pecking order. However, when I tried to set up a network, the new PC believes the network connection is fine, but neither my older PC nor my work laptop can connect.
If I double-click on the network connections, the host and the other computers are sending packets of information, but getting nothing back. I then tested the cable by setting up the old connection again (modem into older PC; work laptop into older PC via crossover) and it worked straight away (once I'd re-ran the wizard on that one to make that a host)!
It is vitally important that I can use my work laptop from home. All machines are running XP. My old PC had an ethernet speed of 100Mbps, does the fact that this one is apparently running at 1Gps cause problems? Can I slow it down?
I read the how to guide (after I'd already done the above, which worked on my older PCs) and the difference is that I already had the modem plugged in and working before I ran the wizard - does this really cause these problems? If so can I undo the network I've created so far?
Any help with this would be gratefully accepted.
