Hooking 2 computers through a router
I am trying to get 2 computers to go through a Cable Modem. They both work hooked up individually but not together through the Linksys 8+1. They are both plugged into a Linksys 8+1 Workgroup GigaSwitch EtherFast 10/100/1000 and that device is plugged into the cable modem. Is the 8+1 also known as a router?
One computer is running Win98 and the other WinXP. The person on the Win98 doesn't want to upgrade to a more modern operating system. Win98 doesn't have much in the way of networking troubleshooting tools because its so old.
How would one go about troubleshooting this to get it to work?
