My old Arris went out after a lightning strike near my home. The Netgear modem has been reliable so far and allows me to upgrade my service to the one gig internet speed

Our old modem stopped being supported by Spectrum and would eventually start to drop the signal. I picked this model up as it's supported, and the signal has been perfect.
