Problems with 5ghz dead on the R720 after heavy usage

[douglas_santos_]

Have my R720 for a good 4 years now and no problems whatsoever.

But then, i bought a PICO4 VR HMD, that is Wifi6e and VERY hungry for bandwith. Using it on 5ghz AC with 160mhz wide channel, it was working just fine.

Then suddenly, the connection stalled and it´s 5ghz WLAN while it´s on and enable, simply don´t have any more power it.

It barelly managed to work at 200Mbps, while it was 1600Mbps just moments ago.

I´ve tried every single option avaliable, updated the R720 to the latest unleashed version put everything on auto or set the setting to no avail.

The POE injector is just fine too, providing 90w as always.

Do anyone have any ideas ? The HMD is fine, i´ve just tested it on another AP and it reached 2100Mbps in AX mode.

Thanks !

Some how our spam filter blocked it, I have now released it from spam.

Ouch ! There was a lot of info there.

I will try to gather it again.

Meanwhile here is the details tab from the AP and the "client"

Hi again, 

Sorry for the late reply. I've managed to install Speedflex on my device and run the tests:

In case it's difficult to read, the results are as follows:

Report 1

0% packet loss

Download = 127.8 Mbps
Upload = 357.2 Mbps

Frequency 5180mhz, Signal -51dB and Channel = 36

I was reaching 1200Mbps with this same config before !

I will try to upgrade my R720 to the latest version again !

Thanks for the help.
