The TP-Link W9980 I use on BT's Infinity 2 package apparently incorrectly showed 0 packet errors permanently for around a year.
A few months back I updated the firmware (after noticing the changelog says they fixed the error counter!) and I have seen pretty similar error numbers as mentioned in this post's title.
So the number of upstream packet errors seem incomprehensibly huge to myself, I don't really understand what is happening and if such a large number is to be considered normal.
The line has been connected for 26days with no disconnections or re-syncs according to the device logs (normally accurate as far as I know!)
The history of the line was 2-3years of full 80mbit running on a old HomeHub before it went nuts disconnecting AND rebooting multiple times per day for several weeks and losing 20mbit of sync.
This forced us to buy the TP-Link unit which solved all the stability issues yet well over a year later my sync speed has never recovered.
So discovering the error count has been pretty surprising, is this some sort of line fault which the TP-Link unit is somehow dealing better with than the old HomeHub could?
