I have instead of monitoring the CRC's and comparing with a different device that i had hooked up before, I look for how long my connection has been up in conjuction if i know DLM needs to make changes. That is why i havent given up.
at the moment since installing last firmware and then resetting and the day after i get a beta firmware (that splits up pathmode in two for down and upstream) then the day after i had pulled the trip switch on electric then realised it was the wrong one and turned my unit off. my DLM profile has dropped and also applied interleave. now im in the process of waiting for possitive changes.
