Question
How do I change the Wi-Fi channel in the SBG6950AC2 gateway?
Answer
In some cases, wireless interference may occur when nearby wireless networks are broadcast on the same channel as the SBG6950AC2.  Changing the Wi-Fi channel in the SBG69500AC2 may reduce wireless interference.  The SBG69500AC2 broadcasts two Wi-Fi networks simultaneously, one is broadcast on 2.4 GHz and the other on 5 GHz band.  The default channel is Auto for 2.4 GHz Wi-Fi network and channel 36 for 5 GHz Wi-Fi network.  The auto channel on the 2.4 GHz Wi-Fi network automatically selects the best or least congested Wi-Fi channel after restarting the SBG6950AC2.  

Before selecting the Wi-Fi network, check the Wi-Fi client that is experiencing interference to identify the Wi-Fi network used by the device.  Then use the Active Access Points tool (located in the SBG6950AC2 Web Manager) to scan nearby access points and occupied Wi-Fi channels.  The tool is used for identifying the least used Wi-Fi channel, then select the appropriate Wi-Fi network and change the channel.  The Wi-Fi client’s Internet connection will be interrupted when changing the Wi-Fi channel.

This document describes changing the Wi-Fi channel on the 2.4 GHz or 5 GHz Wi-Fi network.

    NOTE: A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager.  There is no risk in proceeding to the Web Manager. For instructions to by-pass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.

     
  2. On the Login page, enter admin in the User Name field.

  5. On the System Basic Setup page, determine if the Wi-Fi client experiencing interference is connected to the Wireless 2.4 GHz or Wireless 5 GHz (SSID) by verifying the Wi-Fi Connection Status on the client. 
       
  6. Once the SSID is determined click the More Wireless Settings... link under the appropriate Wireless 2.4 GHz or Wireless 5 GHz section.   The System Basic Setup page will appear.​

    NOTE 1: It is recommended to leave the Channel default setting at Auto and restart the SBG6950AC2.  The best Wi-Fi channel will be selected upon restart.  Keep in mind that the connected Wi-Fi clients temporary lose Internet connection when the SBG6950AC2 is restarting.

    NOTE 2: When choosing to set the Wi-Fi channel, it is recommended to set the channel to 16 or 11 for better performance and stability because they do not overlap.  Other Wi-Fi channels overlap and degrade performance. 

    NOTE 3: Wi-Fi clients will briefly disconnect and reconnect.
