I am currently trying to find an internt filter such as Disney Circle or Router Limits, and neither are compatible with the XB6. I am considering purchasing my own router/modem combo, but I also want to keep my home security active. I went into our local Xfinity store and the guy made it sound really easy - just go buy it and hook it up and it will work, but after reading the forums regarding bridging, sidecars, and all kinds of other stuff that I know NOTHING about I am concerned it isn't as easy as he made it sound. Can someone guide me? Is it something I can do myself?
