Changing the Channel Number on a NetGear CVG824G Router

Sometimes there may be interference between one Wi-Fi access point, such as a wireless router and another such nearby device. Sometimes there can also be interference from other devices, such as baby monitors, cordless phones, garage door openers, and microwave ovens. Interference can result in lost connections and/or slow data transfers. All devices communicating with a particular wireless router must use the same radio frequency channel, but you can reduce interference between different wireless routers by changing the channel number used for communications on one of them.

A W-Fi device will normally support 11 channels. Many devices, such as the NETGEAR CVG824G router, ship with a default seting of channel 6. If your neighbors' devices also use the same channel, there could be interference. When selecting a different channel to avoid interference, it is best to pick one as far away from the current one. So, if the default value is channel 6, selecting either channel 1 or channel 11 is best.

To change the channel used on a NETGEAR® Wireless Cable Voice Gateway Model CVG824G, take the following steps.

  1. Log into the router using your browser, e.g., Internet Explorer, Firefox, Safari, etc., by putting in the address bar of the router (this is presuming you haven't changed the IP addressing configuration for your network). When prompted for a userid and password, use admin for the username and password for the password; those are a default username and password combination used for the CVG824G device. There is also another set of default credentials for the device that provide greater privileges on the device. Those are superuser for the username and password for the password.
  2. Under Setup on the main menu, select Wireless Settings.
  3. In the Channel field, if the channel is set to 6, set it to 1 or 11. You can check to see what channel numbers are in use for nearby wireless networks, such as your neighbors' wireless networks, from a Microsoft Windows system by getting a command prompt and using the netsh command as explained at Netsh command to show available Wi-Fi networks. Look at the channels used for the nearby networks and, if you see a number of neighboring networks are using channel 11, but none are using channel 1, then channel 1 is probably the best choice.
