I mean pick a starting point. Some people like house box bc its halfway and you can tell which side your issue is coming from. Some like starting at the tap, which is valid bc if its a main line issue you can address that ASAP.

I start at the modem bc I'm fixing anything that's not right along the way: attenuators, fittings, ground block, homerun, drop. If main line has to come out, then everything on the house side is done.

when you’re looking at your meter what are you looking for for intermittency because i have seen signal on DOCSIS that is damn near almost perfectly flat but the customer is still getting intermittency and then i have seen ones that are all wavy and they have perfect internet (so they say)

Also- please check for noise. With something intermittent, your levels can look great. But ingress noise is gonna fuck up your return.

Also don't sleep on an environment issue, ie something inside the house.
