I have got my power line extenders set up and they have a connection between the two. Both are 1 Ethernet port out/input.
When I first set them up they had the full internet speed going between them (36Mbps) , however after a day or so the max speed drops to around 5Mbps.
This is then resolved by unplugging one of the extenders and plugging it back in, which then returns it to full speed. Meaning that it is not a peak time of day issue.
I could not find anything else on this, do you have any recommendations on how to maintain the maximum possible speed.
