Low upload speed via WiFi

Hello,

I’m using hAP AC Lite (software versions below) as a wifi access point.

version: 6.46.8 (long-term)
factory-software: 6.40
board-name: hAP ac lite
platform: MikroTik

I’ve noticed, that Upload speed over WiFi is dramatically lower comparing to upload speed when directly connecting same laptop over Ethernet(ethernet ~97Mb/s, WiFi ~0.7Mb/s).
Here are my interfaces configuration:

Could you please advise, how do I troubleshoot, why upload speed is that much different and which configuration updates I could try applying to improve the upload speed?

I’ve also tried a factory reset (system reset-configuration), but that didn’t help.

Ok, in my case it turned out to be Hyper-V configuration on the laptop itself, not the Router configuration. Case closed.
