Are your network settings still there? I.e. if the two computers are on you still can see the other ones?

It sounds like your computer may be, being assigned the same IP address by the router.
Go to Start then Run and type in cmd. When the command line window opens type in ipconfig /flushDNS. When the message stating the command was successful type in ipconfig /release. Not turn the computer off after the command has executed. Do the same with every computer turning them off as you complete the commands.
When all of the computers are off unplug the modem and router for one minute. After one minute plug the modem back in, and wait a minute. Now plug the router back in. Once another minute has passed turn all your computers and network devices (If any) on.
This should force the router to issue unique IP addresses to every computer on the LAN.
