500M Speed issues

switch2scott · 20-12-2020, 15:45

A bit of an issue over the last 5 days, would anyone mind taking a look at these stats and see if the problem can be identified. Speed tests are showing about 200mbps over ethernet (should be M600) and were about 570 a few days ago.

Thanks

power levels are fine on the upstream and downstream but you have got a big problem with rs errors across the board. Did your connection go down this morning or have you turned the shub off? If it has gone down it is for a significant period of time and it may be due to network maintenance to fix the issue.

I was doing the obligatory reset for virgin tech support but got know where

The reason why you are having issues with speed is because of the number of packets being dropped and having to be retransmitted.
