Macbook Pro 16 inch randomly dropping wifi

Hello,

I just got this MacBook Pro 16 inch with a clean fresh install. I have noticed that my MacBook sometimes randomly drops the connection and the wifi just starts blinking up and down like it's searching for a new one. It keeps searching until I press the Wi-Fi icon and press my home network again which it then connects to fine.


I haven't had this issue before with my old MacBook or any other devices and I'm almost next to the router when it happens. It's an Ubiquiti AmpliFi HD with no other mesh units, just the router itself.


I have checked the Wi-Fi logs when it happens and it says the following:


2020-05-02 22:41:30.895809+0200 localhost kernel[0]: (IO80211FamilyV2) AirPort: Link Down on en0. Reason 34 (Excessive number of frames need to be acknowledged).
2020-05-02 22:42:06.284150+0200 localhost kernel[0]: (IO80211FamilyV2) AirPort: Link Down on en0. Reason 34 (Excessive number of frames need to be acknowledged).
2020-05-02 22:42:55.122996+0200 localhost kernel[0]: (IO80211FamilyV2) AirPort: Link Down on en0. Reason 34 (Excessive number of frames need to be acknowledged).
2020-05-02 22:46:48.374067+0200 localhost kernel[0]: (IO80211FamilyV2) AirPort: Link Down on en0. Reason 1 (Unspecified).
2020-05-02 22:47:24.316237+0200 localhost kernel[0]: (IO80211FamilyV2) AirPort: Link Down on en0. Reason 34 (Excessive number of frames need to be acknowledged).


I can't imagine anything being wrong with the settings as it is a fresh install, and I can see on my routers interface that the Wi-Fi has not been interrupted any times at all and even the MacBook can still see the network when it disconnects itself. I'm wondering if it has a problem with the dual-band network as it's both 5 GHz and 2,4 GHz with the same SSID but none of my other devices have this problem.


Any help is appreciated.
