Intermittent internet disconnections - High power levels?

Hello, I have been having intermittent internet connection issues since 16 Sep. Today an engineer came and replaced my Hub 3 with Hub 5. For two hours internet worked fine but it has stopped working again. I think there's something wrong with power levels. Here's my log:
