It is a newer Netgear. I checked my laptop speed it is getting from the Netgear and it says the wifi speed is 72. I wonder why outboard checks from like Spectrum gives me only 45-50?
72 is the negotiated speed between your laptop and the router. It is the best case scenario. Once you start pushing a lot of traffic across, you will find you won't ever get the full amount. Depending on how close your are to the router, that is almost certainly 2.4GHz. For comparison, I get 867Mbps on 5GHz 802.11ac on my laptop in the same room as my router.
