What you're missing is that ALL the PCs will be connecting THROUGH the router to the Modem. Unplug the PC network Cable from the modem, then plug a network cable from the router's INTERNET port into the modem (where you removed the PC's network cable). Now, plug the PC's network cable into one of the ports on the router (usually 4 or more, marked 1,2,3,4. Think of a Router as a "splitter". It connects to the Modem, then several devices connect to the Router, some of them by wire and some by Wi-Fi. So your desktop PC is connected by wire to the router and your laptop PC is probably connected by Wi-Fi (wire is an option, as well). The Router sorts out all those signals and communicates with the Modem. Sound reasonable?

I went from a ATT dsl modem to a net gear modem and i cannot get the net ger mode and linksys mode to talk to the computer


Most DSL providers use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet connections for end-users. To set up a Linksys router, you need to enable PPPoE on the router’s web-based setup page.
To setup a Linksys router with a DSL connection you need to perform four steps:
  1. Verifying Internet Connection
  2. Connecting the Devices Together
  3. Checking the LEDs
  4. Setting-up a DSL ISP on a Linksys Router
Verifying Internet Connection
Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If not, contact your Internet Service Provider.

Unable to set up wireless router


Shut down your computer, unplug the cable modem and the switch. Connect all three - computer to switch, switch to modem. Make sure that the ethernet cable between the router and the modem is in the router uplink port and that the computer is plugged into one of the four ports that look alike. Wait 30 seconds - plug in the modem. Wait another 30 seconds, plug in the router, wait another 30 seconds and boot the computer. Open a browser and see if you have internet access. If you still don't, then try to check the browser by typing 192.168.1.1 into the address bar of the browser. That should give you the browser sign in screen. The Linksys default is to leave the user name blank and type admin for the password. That should give you access to the router so you can check the settings. If this doesn't work, document carefully what happens and post again with your results and we'll try to go from there.

How do i connect a Linksys wrt54g2 to a arris cm450a


Your modem is capable of linking up to a router. What you do is take an ethernet cable and run it form the internet port on your modem to the internet/wan port on your router. From there you connect your pc's into the LAN ports on the router (typically labeled 1-5) if they are hardwired or you connect wirelessly with your laptop. You need to also power cycle/reset your modem when you plug your router in.

Connection


Hi Susie
With related to your particular issue it seems like that your broadband modem is not configured for the router. There are basically 2 types of connection. DSL and Cable modem. Verizon, ATT are DSL and comcast other providers give you a normal cable broadband connection. If its comcast make sure the cable from the comcast modem is going to the internet port in the linksys router and also make sure that there is a system connection the linksys router and the cable from the system goes to any of LAN 1, 2, 3 and 4 ports. Then reset your cable modem by using a pin and inserting to the reset hole in the modem. You could use the same step to reset your linksys router as well .If its a verizon or dsl connection you need to put normally your username and password in the router page. here is the link to how to configure linksys for your internet modem.
Here is a video as well on it?

2. Press and hold reset at the back of the router for about 15 seconds.
3. After 15 seconds turn off the router and then turn off the modem. Wait for a minute.

5. When modem lights are on, turn on router.
6. There should be 4 lights on. Power should be steady green. Internet, WLAN and Ethernet port.
