WiFi Wave2 tx/rx-rate shown as 0bps

We’ve deployed a few hundred hAP ax2 devices with WiFiWave2 running RouterOS 7.10.2.

Sometimes WiFi TX/RX rates suddenly are shown as 0bps for all attached clients (see attached).

We’ve seen this a multiple different customers, haven’t found a cause of a better solution than rebooting the device.

wifiwave2 driver had problems on all ax devices (yours included). Things were greatly improved with 7.11.2 but some users report that 7.12alpha finally resolves problems. So you have to upgrade and see if things get better then.
