You may be surprised at what you may learn once making contact with them.
There are alot of unknowns here so the more you can elaborate on the
details of config and such
would help the list to define what may be the issue.
Also, The cambium forum is a good place to open up for discussion.
I learned tons about the Epmp2000 and ptp550 while on there.

Looking to see if anyone has experienced a similar issue to this:
We have a force 200 backhaul on a small bridged network.
Several times a day now it stops passing most traffic. It can be
humming along at 25mbps down and 5mbps upload and then drop down to
2mbps download and less than 1mbps upload.
Downlink RSSI -65 dBm
Downlink SRN 30 dB
Uplink MCS MCS 14
Downlink MCS MCS15
All remains constant during this time.
The ping falls apart during this time between the AP and the SM
although pings through the network to the SM or through the network
from the AM are both fine it’s just between them that starts to drop
packets.
The units show heavy retransmission packets from the moment the link
is brought online around 40% at times.
At this point I would assume noise is the issue.
*_But here is the odd part I would like some help with_*. Rebooting
the link fixes the issue but leaving the link alone does not. It will
stay “broken” until one or both sides of the link are rebooted. Then
it works perfectly for a time and falls apart again.
Current firmware is 3.5.1 but we have run it on 2.6.1.1 and 3.3 with
similar results.
Any thoughts on how to troubleshot this one would be awesome.
Best Regards.
