Need help with my switch

[Lucky]

About a week ago, I noticed I couldnt connect on more than one computer at the same time using my SMC 16 port switch and RR cable internet. I can post fine from one computer hooked up to it, but any other computer is unable to obtain/renew the IP address. So If I want to use another computer on the net, I have to shut down the functioning one, reboot the other one, and click "repair" in the networking section in WinXP.

Nothing has changed, what would cause this? Any idea? My setup is:

Cable-->Modem--->Port 1 of switch

Port 2, 3, 4 all outbound to various rigs all using WinXP.

Does your switch give out ip addresses? I didn't think they did, but I'm no expert.

After reading your post again, it sounds like you are saying the the one address was being passed around from pc to pc, and that can't be unless you were, releasing it from the first pc. Are you sure you weren't getting a new ip from your isp for each machine?

I dont know jack crap about networking, so I dont know whats going on. Its an SMC EZ Switch 10/100, and up until 4-5 days ago it worked fine with multiple machines. Each machine says "connected to 10/100 LAN" but they are not accessible to each other on my local network, meaning I cant share files between computers now.

I agree with Muadib. If your switch can't to DHCP, you should set up all your machines to class C network IPs. (i.e. 192.168.x.x) and use your router as a gateway.

When you speak of "router" do you mean have one of my machines act as a router?

Ex.,

Cable-->Cable Modem--->Dedicated router rig--->switch--->other computers?

I'll look around on that site but I want to understand what you are saying.

My guess would be that your ISP finally got around to setting the number of IPs allowed by your modem. A few years
ago, alot of ISPs would allow you to pull multiple IPs. Then they got there networks working properly and only allowed
people to pull the number of IPs they paid for.

Your solution would be just as you say, a router between your cable modem and switch. You could either use a computer
with 2 network cards or a little cable/DSL router from your favorite computer retail store.
