Checking an unstable connection

Start with a repeatable observation: when does the slowdown happen, which devices are affected, and does it occur on every site?

Separate local and remote problems

If several devices slow down together, check the router and local connection. If only one destination is affected, the cause may be the route or that destination. This monitor alone cannot identify where a fault is located.

Change one thing at a time

Move closer to the access point, pause a background download or connect by cable. Compare a few minutes before and after each change. Changing everything at once makes it harder to find the useful step.

Keep useful notes

Record the time, device, connection type and symptoms before contacting your provider. Do not publish account numbers, router passwords or screenshots containing personal information.
