SBG6900-AC (v1.5.x): Changing the Wireless Channel

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 SBG6900-AC gateway can improve connectivity.  By default, the SBG6900-AC is set at Auto channel.  This document describes how to change the wireless channel in the SBG6900-AC gateway.

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.
