Hi

Looks like my line latency issues are back with a vengeance. Used to have a similar issue back in 2021 but things improved eventually.

I renewed my contract just over two weeks ago so the irony of the fact I'm now out of my cooling off period is not lost on me.

More then likely its upstream might be DoS by others in your area or you have something uploading you don't know about.

Thank you. Traffic analyser on my router says my connection is practically idle. Just flashed it with the latest firmware though. Let's see if that helps.
