Connect Your Device to WiFi Internet

 

If you are connecting your devices through WiFi Internet, start by locating the SSID (network name) and WiFi Security Key (password) for your modem, and then connect to that network on your device. Your SSID and WiFi Security Key can be found on the white sticker located on the bottom of the modem (example image below). 

 

For further instructions relating to finding and connecting to a WiFi network on your device, see the following:Wireless Device Quick Setup Guide

 

 

SSID-2.4: The name of your 2.4 Ghz WiFi network

 

SSID-5: The name of your 5.0 Ghz WiFi network

 

WI-FI SECURITY KEY: The password used to connect to your WiFi networks, as well as connect to the modem settings

SSID-2.4 vs. SSID-5

With the Cisco Advanced WiFi Modem you have access to two WiFi networks, including a 2.4 GHz network and 5.0 GHz network. 2.4 GHz is the more commonly used network type, and is the network to which you should choose to connect by default, as not all devices will be able to see or connect to the 5.0 GHz network. The 5.0 GHz network typically suffers from less WiFi interference, but will often have a shorter range, so it may not adequately cover your entire home.

 

WiFi Enhanced Protection (WEP) Setup

WiFi Enhanced Protection (WEP) setup allows you to connect to a WiFi network without having to manually find the network and password. If you have a device that supports WEP, you can connect to your WiFi network using this method:

 

  1. Press the WPS button located on the top of the modem
  2. Press and hold the WPS button on your WPS-enabled computer or other device (not all devices support this type of connection) for five or more seconds
  3. Repeat step 2 for each additional WPS-enabled device you would like to connect

Configure Modem Settings

 

To access the modem configuration settings for the Cisco Advanced WiFi modem, start by connecting your modem directly to a PC with an ethernet cable. Although this step is not required it can help prevent issues from arising if settings are changed that cause you to lose WiFi Internet access. Once you have done this:

 

  1. Open an Internet browser (Internet Explorer, FireFox, Chrome, Safari) on your computer
  2. Enter the following into the address bar: 192.168.0.1
  3. Press ENTER on your keyboard
  4. You will be taken to the Cisco login screen
  5. Sign in with the following information, found on the white sticker on the back of your modem
      • Username: cusadmin
      • Password: Your Pre-Shared Key (located on the white sticker on the bottom of your modem)
  6. Select Login to connect

Change WiFi Channel

 

If you find that your WiFi connection is not providing you with the stability or speed that you require, this may be the result of interference affecting the WiFi channel on which you are currently broadcasting. To improve the quality or range of your WiFi Internet network, you can change the WiFi channel that you are currently using.

 

To change your WiFi channel:

  1. Sign in to the Cisco configuration page
  2. Select Wireless from the top navigation bar, and then choose Radio Settings
  3. Click on the drop down menu next to Standard Channel and choose the channel number on which you would like to broadcast
  4. If you would like to change the WiFi channel for your 5 GHz network, simply perform the same steps for the second listed network
  5. Select Save Settings

Please Note: It can be difficult to determine which WiFi channel is best for your home, as sources of interference will vary. The easiest method for discovering this is to simply pick a channel from the list and test it. If the connection does not improve you can repeat the above process to test with another WiFi channel. You may need to do this several times before you find the most effective WiFi channel for your area.

Create a Guest Network

 

With a guest network you can allow guests to connect easily to your home WiFi, while still protecting your personal information, files, and devices from intruders. You can create a guest network for both the 2.4 GHz and 5 GHz networks.

 

To enable an unsecured guest network in your home:

  1. Sign in to the Cisco configuration page
  2. Select Wireless from the top navigation bar, then choose Guest Network
  3. Select the option for Enabled next to Wireless SSID (this enables your guest network)
  4. Select the option for Enabled next to SSID Broadcast (this allows users to find the network in their devices list of available networks)
  5. Select Save Settings to save your changes

 

You can also change the name for your guest network by updating the "Network Name (SSID)" field.
