getting 20km wireless link issues

i have p2p link with mikrotik netbox metal about 20km link.. i get problems like link slow .. low bandwidth passing from 6PM to 11PM… only winter season.. any solution ?

Did you check if the signal gets worse during that times?

I experience the same issue but only with links longer than 80km just before the summer starts

Hello, I have a throughput problem with a 24km PTP link, with settings the values ​​are good (reaches 17 Mb) and all of a sudden they drop to stay in Kb. I really tried everything I set one in bridge the other in station, station bridge the same. Recently I put one in bridge and the other in WDS station by activating WDS the same and I noticed that the alignment values ​​have become -85/-57. i use netmetal 5
