I expect line issues because of the way this product works but I get a download speed of less than 1mbs and an upload speed of 10 or more mbs. This is opposite of the expected result. I have reset every device on the network. It does perform very well when plugged into an outlet in the same room. Also an expected result. I have updated the firmware as well. This is being used in a camper attached to the house circuit and it should be a go, no go application because of that but the devices see each other and connect so the poor download but decent upload speeds are baffling me. Upload in the house is only a couple mbs faster than the camper. Download in the house is 287 mbs vs the .9 or so in the camper while connecting to the tp-link.
