I have two Tp-Link Pharos CPE210 at distance of 100m, LOS, no big noise on them, this is the status on the server antenna:

This is the status on the client antenna:

These are the speedtest executed on CPE210 tool and with a Raspberry PI directly connected to the client router:

If you look at the results they look different yes but they have the same trend, the download bandwidth is way lower that the upload and I can't figure why as the TX/RX rate in the status look the same. Any idea on what could be causing this asymmetry in TX/RX?
