I am having issues with my Netgear Nighthawk D7000 router. Wired connection is fine I get 60 download and 17 upload, which is my provided speeds. However, on wireless, no matter what device, I am getting fluctuating and slow speeds. It can drop to 0.3 download speeds. I connected to nordVpn on my phone and the speeds shot up to near the wired speeds. So I thought it must be the QOS prioritising traffic. However, the QOS is not enabled on the router. I even enabled it and tested it, then disabled it and tested it, and no change. Please help.
