I have 2x PTP450 units and I'm seemingly getting disconnected at exactly 2 minutes every 2 minutes. We thought we had an alignment issue, and verified that we were within acceptable parameters there, then we thought we had a noise issue, but confirmed there was nothing interfering.
I thought it was wonky, but when I actually got down to it and figured out it was exactly 2 minutes, there seems to be perhaps some kind of software setting causing this.
What type of product? Model number? What software version are you running?
A full CNUT capture will be asked for by the support team, but will provide the full configuration, and they might be able to tell something from that...
