Good morning

I recently (two weeks ago) installed our Wireless Wire cube pro kit and notice a constant 0-3% packet drop and wonder if it is normal beheaviour or if I did something wrong. It is the first time I install a 60Ghz link in our company. I kept the default config and only changed the IP and regional settings.

This is what the monitor command shows me:

tx mcs: 10
tx phy rate 3.0GBps
Signal: 100
rssi: -42
Sector: 27
tx - sector-info: Left 0.8 degrees, 0.8 degrees down
distance: 150m
tx packet error rate: constantly fluctuating between 0% and 3%

Firmware? Latest?

Firmware? Latest?

I believe so. RouterOS 6.49.6

Too old for CubePRO. Use 7.4.1 (7.5 have bug for client side)

Will I lose the current configuration if I upgrade it? They are already in production and cannot be offline for too long.
