The hardware in the SBG6900-AC only supports DOCSIS 3.0 and earlier.  It cannot be converted to D3.1 with firmware update.   


You’ll need to replace your SBG6900-AC with DOCSIS 3.1 model like SBG8300, G34, or G35.  


Your DOCSIS 3.0 unit should still work with your cable company if you don’t want to upgrade
