Oh yea, I opened a ticket about that last year, forgot about that. Added it onto the todo for tomorrow, CPE is in a stupidly awkward place after the furniture was rearranged >.<Edit: Testing with a LAN cable to the Vuma CPE, seeing full line speed this side. Their handover server seems fine. Can you run 2 tests, connected directly to the CPE, from two computers (if possible). Vuma logs MACs of each and every test. As long as they don't see a router MAC in the results, they will be quicker to respond. Update your ticket with these results please. Likely a dying optic and easy to fix.
