I am seeing some T3 timeouts which typically indicates issues on the cable lines that a tech would have to come look at. are you seeing a lot of uncorrectables on the power level page?

I'm not certain where the power level page is. i took the advice of someone who though 52 dbvm was on the high end so I bought this device and installed it. The upstream power level is now at about 38 instead of 52. So I will try this for a while and see what happens.
Well, so far so good. Only had one disconnect in the last few days.
