Interesting read, this thread, as we have been faced with the same issues since the beginning of the month. We moved into a house in Kenilworth a few months ago and there was existing fibre internet. For the first 2 months we just took over the old owner's account and the internet connection was flawless. I cannot remember who it was with, I believe it was an Octotel line (could be wrong, perhaps it was Openserve) and the ISP I'm unsure of too, as the account was via some weird 3rd party. Long story short we had no issues until we moved over to Cool Ideas at the beginning of November, on an Octotel line. Ever since that day, we have had multiple disconnects per day. It either reconnects of its own accord after about 20mins, or we need to reset the ONT and router. We're on day 28 of this now, and considering my wife works from home it's been, and still is, a nightmare.
It's been escalted to the top of Cool Ideas management apparently (CEO we've been told) and supposedly the same with Octotel, Justin has been in contact with us - but no solution from either side.
It was suggested that we just move to an Openserve line, so we've requested (yesterday) that Cool Ideas do this for us ASAP, and judging on what I've read above this will solve this ridiculous issue.
