Of note; allegedly within '10 days' still of the 'negotiation period' to find out the speed. ADSL router/modem connected to 'test socket' 24/7 and connection intermittents happen from 5am to 12am knowing at least each day. Also tried alternate filter.

Now after 10 day period. If connectivity issues ensure, time to contact VM.
