tl-pa7020-kit 1gbps suddenly going slow.
I've been using my tl-pa7020-kit for about 3 years now without fault, moved house about a year ago and they were perfectly fine.
I have however the past few weeks been having an issue where my net speed simply won't go beyond 150/160mbit. It's not my Internet as I get over 410mbit of Wifi 5Ghz (phone).
I installed the TP Link App which I never knew about and speeds are all always above 500mbit, they fluctuate from 550ish to 800ish.
Anyway, tried new cables (to router and pc) tried moving the plugs, changing ports in the router, changing ports in the powerline adaptors.. nothing.
I'm totally stuck, so they're either knackered or there's an issue with all 4 ports on my Virgin Router.
Any Ideas? And no, no new devices plugged in, nothing new / no new devices no changes nothing, entire house is "as is".
Oh even tried a brand new fresh install of Windows 11 (today) to no avail.
