I tried with two Nighthawk Routers R6700v3s that I got from the Amazon Store by the Empire State Building
Both would work for 2-6 hours at a stretch and then lock up. Verizon of course was no help, the Netgear people after having me do firmware upgrades and MAC cloning concluded by saying that their router was not compatible with the ARRUS ONT that Verizon had me hooked up to and offered to sell me an ancient model instead.
Does anyone have an option that works? (I already have a MOCA adaptor which worked fine with the Nighthawks when they weren't locking up.)
