Comcast, multiple computers, whats the fix?

post #1 of 26
Thread Starter 
i know ive seen people with problems making multiple computers work through comcast due to only having one ip address or somebull**** like that. ive got 5 computers and 3 laptops hooked up to a switch. the guy just came in and switched everything out. 1 computer works. how do i get the new router to work with like... more than 1 computer attached? and no, no crossover cables.

You are going to need a router in order to get internet on all the PCs. The router will act as a gateway to the comcast internet connection. Just using a switch will only allow 1 PC to get an address from comcast.

Something like this for a wired connection or this for wireless capabilities.

What guy came in and switched what out?
Switches and routers are different things. A switch will not work after most modems.
Do you have a switch or a router after the modem? You need to have it Modem -> Router -> Switch -> Computers (or Computers after the Router along with the Switch).

thanks, thats prettymuch what ive figured out.

2nd issue. my family cant live without internet for multiple days. so i need something local. not hard if we only had 4 computers.but we have 4 computers.... and a 360.

so... can you daisy chain routers? have a 4 port have 1 port in, 1 port going out to act as the port in on the other router and have 2 ports to 2 computers, then have 1 port in from the other router on the 2nd router, and have 3 outputs to other routers from that 2nd router?

ima hope someone understood that....

unless im reading the descriptions wrong where 4 LAN ports means 4 LAN ports...+ an input slot.

You only need one router... you need either switch with more ports or daisy-chain switches.
Once again...

If you go pick up your router then hook one port from the router to the switch, and plug in your additional components to that, you will be good to go

so we can have the modem/router/whatever the hell he installed, plugged into a router with 4 ports, and have that output to a switch? ah, and the modem will assign IP's through the switch... oops forgot about that.

OK, go out to Worst Buy and get one. You can daisy chain your existing switches to the router you're about to buy (which will have a built-in switch as well). As for the cable modem you just got installed, it probably isn't a router.

But if you alread have 2 routers and no switches, you can make the 2nd router act as a switch (depending on brand and model, and you usualy loose one of the LAN ports).
But if your going to be buying the stuff, you just need 1 router and 1 (or more) switches.
Switches are cheaper and easier to set up (just plug in) than doing 2 routers.
