I've been consistently getting 79.99 Mbps download for ages. Today I saw an engineer at the cabinet. My router log shows it disconnected the same time the engineer was at the cab. Now my download speed has dropped at 72.83. I've restarted just now about ten hours later and it resynced at that exact same speed. Is it possible for an engineer to be working at the cab and cause this scenario? Thank you.
If the engineer was working in the cabinet at the same time as the connection dropped. I would say it likely the contributed to that disconnection. As long as you leave your Router connected and the connection remains stable you should see the speeds return to normal.
