Cable Modem connecting issues. Please help

[Snipor]

I have a surfboard 3100 cable modem. I don't have a single connection however. I have a 2 person connection. Anyway, I needed the ability to have more than 3 computers connected so I invested in a Cable/DSL router. NOw heres the problem. All the 4 of my comptuers can connect. However, when the fourth connects, my pings goes to hell. For example. By myself or with two others I average approx around 120 ping to my game servers and such. But I connect the fourth to internet and all my pings on all the machines go to like 850 ping!!! Web browsing is almost impossible due to the high pings, I keep getting disconnected. Is it possible that I'm using up my bandwidth on a cable modem? That can't be. My cable company has a plan to allow 10 computers connected to them through a single cable modem (that's just using a switch connected to the cable modem, so you physically have 10 different ip's, but using the same modem), so it should handle 4 through a router. Any ideas?

Remove TCP/IP and reinstall it on the fourth machine, one one causing the problem. If there is no difference reinstall the NIC Driver on that same machine. Make sure that the TCP/IP Properties are set with wins Cinnfiguration set to Disable WINS Resolution.

What will setting Wins Resoluting to disable accomplish? Is this something that is supposed to be done when using a router? I"m not too familure with networking, a simple explanation should be sufficient.

Also, when I stated "4th computer" up above, I didn't mean one in particular. Any additional computer after 3, causes my pings to go to crap. If I get off the web on any one of the machines, the others go back to being fine. It isn't specific to one machine. If seems like I have a bandwidth cap or something on my connection to my provider maybe. Or maybe a setting needs to be chanced on the router. No clue.

The WAN side should be set for DHCP and the LAN side can be DHCP or Static your preference. Try resetting all hardware by turning everything off and unplug the router and cable modem from electricity for about 1 minute then restart everything again. If problem continues contact the manufacturer of the Router.
