Is there any high power appliance near the powerline units? Have you tried changing the place where you plug? According to your description, it seems there is some high network or electrical activities which affect the speed of PLC.

My speed from the router direct is about 100Mb/s and I have achieved the same with this Poweline adaptor before plenty of times. This drop in speed seems to be happening even more often these days and I am struggling to find the cause of the issue.Screenshot from TP Utility: https://i.imgur.com/3DF2bsF.jpgSpeed test (this was a better one!): https://i.imgur.com/3DF2bsF.jpgAny ideas? I've tried factory resets, general restarting/syncing stuff. I've got the latest firmware (apparently) and I'm running out of ideas! I've even been using it before while it was slow and it suddenly became fast... This is without any other internet being used in the house.Any thoughts or help would be appreciated!Thanks.
