I am having problems that resemble this issue with my MA2500D adapters.
I have a very simple network: I use the MA2500D devices to bridge between my two rooms in the house using my existing satellite cabling, which has 2.5ghz splitters.
This worked reliably for a while, but now is getting very unreliable. I started monitoring the connectivity and this is the graph showing when the connection is 'up' or down, based on pinging the device from my server: it's been up about 2/3 of the time in the last 24 hours, and is currently "down"

Can you give me any hints on how to diagnose and fix this issue? Is there any reason I can find for the connection dropouts?
