RBE771 slow download
I'm having the same issue but everything I've tried is over a wired connection - no wireless. This is what I've experienced. I've just started using Ziply Fiber and signed up for the 2000Mbps...

Thinking that something might have changed that caused this issue, I switched back to the old RBR750 (only supports 1 Gbps). I once again got ~900Mbps down and ~850Mbps up speeds using the Windows based Speedtest on the two Windows systems. Just to clarify, the only thing that has changed (between these two tests) in this environment is the Netgear router. Nothing else has been modified.
I suggest trying some other tools to measure speed (and also trying some different Ookla servers).

During my testing I tried several different Ookla servers. Same results.
One other note - if you search the Netgear forum there are other similar complaints.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.What Windows version are you using?
And speed testing at the Fiber box with a ethernet connected device see's over 1Gb?
Are you using Ooklas web site in a browser or there speed test app on Windows?
Try disabling the following and see:

Ookla isn't sending massive amounts of data in their test. They are instead measuring packet timing, and estimating the throughput ceiling from that. When you send packets back-to-back (one right after the other) then the difference in arrival times gives you an estimate of the slowest link speed on the connection path.
This technique doesn't always work well, so I do suggest trying some other tools (there are several free sites, and your ISP might actually host one). These will also be using packet timing, but the algorithm details do vary.
Also, their windows app will be more reliable than the browser, especially when measuring fast link speeds. So install the app if you are just using speedtest.net.
Note I'm not saying there isn't a real problem. Just pointing out that there are situations where speedtest misbehaves.
