X Tech just left and checked all the connections, splitters, etc. and concluded I am getting great service up to the modem (a 3 year old Motorola MB7621). He recommended buying a modem+router combo, DOCSIS 3.1. He liked netgear. The choices are overwhelming and costly!

Any suggestions for a home (2 adults, 2 kids) with basic needs that is a) a combo, b) good value and c) will last for 3-5 years? Thanks!
