High packet loss, Area 12
In the B37 6 area of Birmingham, I've been getting high packet loss warnings from about 1520 continuously. The amount is ranging between 19-21% and is causing my router to switch to its fallback connection. There's nothing in the router log to suggest anything amiss, except for dozens upon dozens of profile changes: Time Priority Description 31-08-2025 17:01:29 notice US profile assignment change.

We'd been having consistent connection bounces before that. Approx 2 months ago we had to replace the Hub5 because it completely failed - dead, no power, no response. Any thoughts anyone?
