today I bought TL-PA4010P. Unfortunately, my Internet speed drops significantly compared to direct connection to a router (I guess it's not going to be same speed, but mine drops way too low). I'm providing screenshots from speedtest and tpPLC. I used the same end device with same cables.
End device connected directly to router
End device connected via TL-PA4010P
tpPLC (not sure what powerline rate means and whether it affects the speed or not)
Is there anything I can do to increase the speed?
