2nd PC hookup to modem
« on: June 18, 2009, 05:00:11 PM »
Would I be able to hook up a 2nd PC to my cable modem using a splitter?

Does your modem support more than one PC, ie router as well? What you may want to do is chainlink them. That is run a cable from one PC to the other. Then give permission to share internet connections from the control panel. I'm not sure of the exact series of steps but it should be in the help file of your OS. I've done this in the past. Your going to need two ethernet ports on at least one computer. One for the modem and one out to the second computer. If those don't exist on your MB then you will need to buy a Network Interface Card (NIC).

You'll more than likely need a router.  Most cable modems do not have 'routing' built into them like DSL gateways do (which are basically DSL modems and a router together in one box).  Depending on your needs, they can run from $20 for cheapies up to over $100 for higher end gaming wireless routers.  You'll be able to find a router (either wireless or wired) at any Walmart etc.

Basically, you need the Router to assign that 2nd computer an IP address.  The current one you are getting is assigned by the cable modem (which can only assign one)

I had a cable modem running into a router before as well. Probably the way to go over chain linking. But, if you have 2 computers and one has 2 ethernet ports you can chain link and save some bucks.

Router,  a splitter will only allow one system to connect at a time.  Routers can be had for $25

If your ISP gives you more than 1 IP you can use a plain switch and your computer(s) will get IP's directly from the ISP. I can have 5 IP's in my connection.

A router would be a good option if you can't have more than 1 IP and/or you want the added security of NAT (meaning your computer is not directly connected to internet anymore, other computers out there can't see your computers direct address). But NAT can give problems with P2P and even some games so it's a tradeoff.

the only problem i have with stand alone routers is they are easy to flood out and lag one of the computers.

Yep consumer level routers suck. How many times I've had routers crash when doing simple ping etc. Or how many times consumer routers have needed reboots..

It takes a small business level non-blocking router to handle a couple gaming machines without hiccups. That's why I brought the switch up.

The WRT54GL isn't so bad about clogging up, I've noticed. The straight G has a bug in it that causes the router to listen to a connection (even if it's been closed) for days IIRC. The GL runs a different internal OS and doesn't suffer from this. You can also get some good third party firmware that will solve many of those problems at the cost of your warranty.

I've told Comcast I have a router and they've never charged me extra.  If you do have an issue of any sort though they always blame the router and tell you to disconnect it because it's "not supported".


I've got a consumer level Linksys wired/wireless router and I've never had any problems with it in years.  I have to re-boot it maybe 2-3 times a year.
