I am just about at my whits end here and I don't know where to go from here.

I have had CONSTANT internet issues for well over a month now, at random intervals during the day, the internet will drop out completely, ranging from 5 seconds to 8 minutes. I have setup traceroutes and continuous pings to run 24/7, and when the internet drops out, I can obviously ping my internal gateway, and the external IP of the router, but the next hop and beyond is unreachable.

First they told me I had to turn off bridge mode, and disconnect my personal equipment, so OK I did, issue continued. Next I was told I needed a technician to come out to my house to check it out, which happened last weekend. He tested the coax, and said the signal seemed fine but he had heard there was issues in the community, and it should be resolved during the week, and to check back in with support, and he replaced my modem just to be safe.

I waited until near the end of the week, and contacted support who said the community issue was "resolved" and my signal to noise ratio was "much better" now. No change in my issue, still constant throughout the day... the support technician told me to try bridging my modem again, so we did that, and low and behold, issue remained. I had another technician out at my house today, who said he thinks I received another dud modem/router, so he replaced it again today and left. The issue STILL exists, and the internet has cut out 15-20 times this afternoon/evening, and although BlueSky keeps working, Netflix running on the box does not (it cuts out for the same duration as the internet).

What do I need to do to get this taken seriously and looked after once and for all? It is clear to me that the issue is somewhere between my modem and the node it connects to.
