    Excellent choice in a combination router/modem!

    Great combination modem and router. Saves space from the old setup. Needed this to take advantage of the current internet speed. Easy setup and works great!

    A good update from an older Arris

    After trying to connect this unit to my Xfinity service, I ended up first calling Xfinity for help (they had messed up my service due to a move) and then calling Arris because the Xfinity tech messed up the setup by not following Arris instructions. HOWEVER, Arris totally fixed the Xfinity oopsie and got me up and running. I bought this modem/wifi to replace an older one that no longer worked with Xfinity. I am pleased. Connectivity is faster and the thinking dots are now minimal rather than constant. Arris tech service was really patient and qualified, identifying the problem and fixing it.

    Arris router

    Difficult to set up ring cameras, everything else setup ok. Yellow light blinking on back, suppose to be green but still works.
