Modems/Routers are offered by the following companies:
Motorola, ARRIS, Netgear, Linksys, Cisco and more.


Internet Service Providers or ISP offer a connection from home to internet. These providers will contract with you for a monthly charge and usually offer the required hardware to connect home to their hub and on to internet. The hardware usually consists of a modem router box typically with Wi-Fi so you have wired and wireless communication at home and the cable connection from the modem to the ISPs local network.

You can have the ISP install your home modem/router or you can do a self-install with a provided kit. Locate the modem/router in a central location away from any devices which may cause interference. Connect the modem/router to the ISPs cable coming into the home. This could be a coax cable or a fiber optic setup or a combination.

Plug the modem into a power outlet and wait for all the front panel indicators to appear. Notice which lights are on. You can see if the Wi-Fi indicators are on or off. Your ISP may require an activation of your modem before you can get connected. See below.

Security Label

Look on the rear, side or bottom of the modem/router to find information called a security label which has your default Wi-Fi password, network name (SSID) and IP address or login. Also you should see the default login name for the router and the default login password. You will need this information to setup or modify your router settings.

On the left is the IP address you use to login to the router from a web browser.

Instead of, you will enter into the web browser address bar to gain access to the router. Your router may use a different IP address but it is usually or or so this is where you find the IP address of the router. The router should present a login page on the browser. Look on the security label to find the default user name and password. Usually it is simple like admin and a password of "password". The example above is admin and a password of motorola.

Connect an Ethernet cable from the router to a laptop or desktop computer. If your computer is already setup for a broadband connection, make sure the modem/router is powered up completely and then you can test for connectivity by pinging the router.

Type CMD in the Windows 10 search bar and press enter, you should see a command prompt. Next type PING or whatever your router's IP address is.

If you have connectivity, you should see the results such as above.

RESET to factory defaults

If you cannot login to the router, you may need to do a reset of the router so that the default username and password are restored.

Keep in mind this may flush any settings already established in the router so do this as a last resort. Try to find this information from anyone who setup an old router if it was not you.

Performing a Modem/Router factory reset is a troubleshooting step that can resolve a large number of common networking problems and restore the default login name and password. It’s important to have this option as it can prevent having to call your internet service provider or have them send out a technician. It takes just a few minutes, but can mean the difference between you needing to miss work for a technician call versus taking a few minutes to hit the reset button on your own.

Plug in your Modem/Router and wait for it to power on completely (about 3-5 minutes)

Locate the reset button on the back of your Modem/Router where the other ports are

Press and hold down your reset button with a small toothpick or paperclip for 30 seconds

Wait 3-5 minutes for your Modem/Router to reboot and reset
