After a successful build, we were able to make everything work for a while, then started to have a problem with the topside adapter going dark (all three lights out) after about five minutes. Finally it has gotten to the point that none of the topside board lights come on at all. (We have a version 2.6 ROV with version 2 Tenda boards).
Although we have no lights on the topside board, the ROV starts up normally (judging from the lights and expected startup sequence) but of course we have no Ethernet connection.
I have replaced both the Tenda homeplug boards, mashed the connectors together to ensure good contact and generally messed about with no change in the symptoms, so now I’m stumped! Any suggestions?
Thanks - this is a great project and we have had a ton of fun putting it all together - now we want to dive! Dive! DIVE!
