I am experiencing slow speed using the extender. Have 100/100Mbit/s. My router is a gigabit router and it gives back the purchased speed. The electric wires has been changed last year (total renovation).

When I connect the extender, the speed drops on the powerline ethernet output to about 20-30Mbit/s both up/download, and he connection is unstable. Using other power output does not help, I get the same results.

WiFi speed is bad as well. How can I fix the issue?

Thanks for any help!
