I think you problem not with radio, it not possible to interference in this case, check ethernet

No, uptime over the year, ca. 15 item

Post full configuration, how many channels you use ?

Show wireless settings and signal . -80 noise too high, 36Mbps too low for signaling speed. Change frequency

ìt really work ! PtP 20MHZ TCP 1. 802.11 105/100 2. NV2 90/80 nv2 work what never before on ARM, but we wait continued improvements This still shows 802.11 is better? What signal strength on both ends? 1 stream tcp or more? Test between the two devices or from devices behind the two radio's? (like ...

ARM-ARM BRIDGE or P2MP works like that very unstable & slow!!!!!!!!. MIPSBE-ARM works good only in pure 802.11

ARM-ARM work ok , 120 Mb TCP 20mHz in 802.11 , some packets lost, but very low
only NV2 problem

Nice work, thanks Mikrotik, update from RC51 to RC56
