Same here. I bought the same system from Costco back in late March or early April. Nothing but problems since day one. It's a bigger house I just moved into and bought the Nighthawk system to give me more coverage than my previous system, a single Google wifi puck. My speedtests have consistently been all over the place from 7Mbps to 236Mbps. I get 200 from my ISP. I first thought the problem was the ISP so I had their tech come out and spend an hour testing everything. All the tests he ran directly from their modem came back at 235Mbps. As soon as he connected the MR60 and hardwired his tester to it, it tested at 80Mbps.
Nothing has changed. This morning I tested it and got 7Mbps. Next test was 80Mbps.
I've tried everything Netgear support has recommended and nothing has fixed it. As a matter of fact, much of what they had me try made things much worse. After the firmware downgrade they had me do, my Nighthawk phone app stopped being able to connect to the router. I had to reboot everything 3 or 4 times before I could get that working again. DL speedtests directly from the app or from the router's web interface are between 70 and 80Mbps.
I never had any of these problems with the Google wifi puck. I'm thinking of returning the Nighthawk Mr60 system and going back to my Google puck and just buying a couple of additional pucks to better cover the new house. One puck alone won't do it.
The downside to the Google system is that it doesn't have the configuration options the MR60 does but on the other hand, I just plug it in and it works....no issues.
