It seems that we can see the link rate on the utility.

Why not buy the other model of powerline adapter? They can work well together!

lupryce wrote I have a similar issue; my TP link extender was working, but for whatever reason has stopped. I can see the TP link wifi as full signal on any device, but nothing will connect to it....

The MAC address of RE200 that would be displayed in the DHCP client list of router is not the one you can see in the web page of RE, which is called real MAC. It is equals the real MAC add one....
