How to get rid of the warning message about Load termination timed out.? #19

Closed mcuee closed 3 months ago

mcuee commented 3 months ago

Sometimes I will get the following warning, when testing wireless.

Warning: Load termination timed out. There may be residual untracked traffic in the background.

Just wondering if this is a real issue or not. If it is a real issue, how do I debug and get rid of the warning? Thanks.

That may happen due to the TCP termination being lost or TCP incompatibilities between OSes.

It's likely benign if you see bandwidth and latency drop to idle numbers after the tests in the graph. Which we do see in the upload test with the extended wait for the TCP termination packet.

I see. Thanks. I will close this issue then.
