Sharing a Wired ethernet connection with a router?

I currently have comcast cable and I trying to figure out of there is a way to share the connection without having to purchase a router. I have a standard workgroup switch. My cable modem runs VIA eithernet to the switch but only my desktop can use it. I am assuming this has something to do with the Mac address. Is it possbile to hook up another computer to the switch via eithernet and also use the connection? Unfortuanety I dont think ICS will work because it changes the ip address to 192.168.1.1 or something like that and I have to use a comcast assigned I.P

Any help would be greatly appericated.

Thanks

P.S I posted another thread similair to this about doing this wireless. The response was basicly dont bother, to much work. Now im looking at doing it wired.

 

If you have a second NIC on one of the XP machines you might be able to hook the 2nd PC to the 2nd NIC using a 192 address scheme then hard code some DNS info and see if that works. But you need either a router or a 2nd NIC to get this to work.

 

Using a hub, switch with an internet connection and several computers is NOT the way to go.
Could get into details of why not- but don’t feel like giving a tutorial right now.

If just want to get on internet with second computer. Just turn everything off, only power up hub and 2nd computer. OR - you can plug 2nd computer directly into modem- same thing.

OR - you can purchase a 2nd internet address from ISP - 1 for each computer.

OR - you can buy a router.

Basically. you purchased 1 internet address from your ISP.
Only 1 thing can connect to ISP at time, either a single computer or a router (which will then split things out to multiple computers).

If want to go wireless - buy a wireless ROUTER.
You can still have a hub - but the hub should then be plugged into the router.

 

I would just get a router. They are super cheap these days. I got one that had a print server and 4 ports for about $10.
