Question
How do I change the wireless channel in the SBG6400? 
Answer

When using a wireless connection, interference may occur.  One variable may include other Wireless Access Points within the surrounding area and if those Wireless Access Points are using the same wireless channel, this may cause interference.  When experiencing wireless interference when other wireless access points are present in the surrounding area, changing the wireless channel within the SBG6400 gateway can improve connectivity.  By default, the SBG6400 is set at Auto channel.  This document describes how to change the wireless channel in the SBG6400 gateway.


Changing the Wireless Channel

  1. Launch a Firefox or Safari browser.  Enter http://192.168.0.1 into the address box, and press the Enter key.  

    NOTE: A browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager.  The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH.  The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser.  Safari browsers on Apple PC and mobile devices are not impacted.  The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1.  For workaround instructions refer to article # 19435 - 192.168.0.1 uses an unsupported protocol. 
     
  2. 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 bypass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
     
  3. On the Login page, enter admin or a customized username in the Username field.
     
  4. Enter password or a customized password in the Password field.

    NOTE: On later versions of the SBG6400, the Wi-Fi Security Key is used as the default admin password printed on the bottom white label.  For assistance with Web Manager Access, refer to article # 18730 – SBG6400: Web Manager Access.

  7. On the Wireless 802.11 Radio page:
    a.  Channel - Try a different channel than what is displayed as Current.

    NOTE 1: It is recommended to try channel 6 or 11, if it's not listed as Current.
     
    NOTE 2: In the Wi-Fi spectrum, there are multiple channels that overlap and degrade performance.  Because channels 1, 6, and 11 do not overlap, they are used for better performance and stability.

    NOTE 3: When using 2.4 GHz band with 40 MHz channel, there might be interfere on legacy 802.11b/g devices. 

    b.  Click the Apply button.
