I have been having problems with this link, it starts reporting no signal on the AP side, 19km link and 32dBi Netpoint brand antennas.
Hi @cperalta ,
when it reports correct NF and no signal over some sub-carriers only it can signify interference.
Did you try to change frequencies, choose some narrower band?
I would suggest you to Raise Ticket in the top right of this page and attach techsupport files from Master and Slave with SA enabled for 15min.
Our engineer will assist you to isolate it. It is free of charge.
