You have good singal.

You are on VHT80 with MCS 9 NSS 2 with Short Guard Interval (SGI).
That's the maximum possible on VHT80.  That should give you 3-500Mbit/s
RX locally as single user.  At least others have reported that.

It'll be a few seconds before the firmware will fully ramp up to use
that but it seems you managed.

Hard to say what's going wrong without much further debugging.

What kind of speedtest were you using?

Do you have any chance to test a local target?
