have a PTP with Mimosa B5lite with less than 3km for a tower, every day at 7pm I lose access to the PTP antennas but I still access the antennas after the PTP, which indicates that the PTP is working, the 8pm returns to normal and I have access to mimosa again. Firmeware is up to date.
It sounds like a IP filtering issue. If you’re running the most current firmware (1.5.0), log into your B5L radios and go to Management. Turn off the “Firewall” option and let me know if you see issues afterward.
