Modem and router won't recognize 2nd computer or xboxes


Recommended Posts

Hello dolaronron, and welcome!

The first thing you want to find out is:

A) if it's a problem with the modem (doesn't seem likely)

B) if it's a problem with the router, or the ports in the router

C) if it's a problem with the computer, or the ethernet port for your network card

D) if it's a problem with the cables

The best way to find this out is to connect a device direct to the modem and try all the cables with it.  Also, switch around with the ports in the router.

It is also important to be power cycling properly when you are switching devices (device = PC, XBox, router).  Powercycling in the right order is key to good communication between devices and is especially important when you have a router involved.  What you want to do is:

-shut everything down (PC's, XBox's, router, and cable modem)

-let it sit about a minute and tighten up the physical connections

-bring up your modem first and wait for 4 solid lights (power, receive, send, online)

-bring up the next device (router, or maybe PC if directly connected)...you should see a flashing amber "PC activity" light on the modem

-if you just brought up the router, then bring up the PC's and XBoxes.

Also, maybe check the device manager in the emachines PC to see if the network adapters are showing any conflicts.

This is just a start, but covers a lot of hardware-related bases, which sounds to be your issue.  Try these and then get back if it don't work!
