I've had the same issue with Cool Idea's for several months, actually on and off since I started using them 2 years ago.
Often they have mentioned maintenance or an outage. Somedays no issues, other days disconnects every 20 minutes for 2-5 minutes at a time, it is SO incredibly frustrating.
Oddly enough, the solution was to log into the router and click disconnect/connect on the WAN connection, which would solve the issue.... So i'm accustomed to running a constant ping and logging into my router as soon as the packet drops start, to disconnect/connect.
The issue seems to be exacerbated by the routers they provide, the TPLink Archer 750's. For a while I plugged my PC directly into the ONT, configuring a PPPoE connection via Windows, and never had a single issue for weeks. Eventually I got a router replacement from CI and the SAME DAY the issues started again.
I also recently purchased a Mikrotik, which I used for the PPPoE termination and have configured the TPLink in bridge mode, which seems to be significant improvement. While I do still get occasionally drops, its not significant enough to kill what I'm doing at the time.
So if this is an Octotel issue it would be nice if they could figure out wtf is going on and fix it.
Just to mention I'm in Tableview / Cape Town.
