Hi, welcome to the community.

Have you used any powerline adapters before?

-Since the powerline speed is closely related to the Home electric wiring system, if the house is very old, the powerline performance is even worse than the wireless performance.

If you want a seamless Mesh system, I think Deco is more recommended than the Archer EasyMesh solution.

Deco XE75 Pro would be a great choice. If you have used powerline adapters before and the performance is quite good.

We could use the powerline bridge to establish Ethernet Backhaul, such as:

ISP internet entry point---main Deco XE75 Pro---master powerline adapter~~~~~extended powerline adapte r#1---<cable>--satellite XE75 PRO #1

                                                                                                                      \~~~~~extended powerline adapter #2---<cable>--satellite XE75 PRO #2

Thank you very much and best regards.

Hi, 500-750Mbps out of AV1300 powerline speed is quite great.

For a Wireless Backhaul Mesh system, the internet speed of the satellite Deco would be 50-80% of the main Deco varying in wireless interference/barriers and distance, So for example, if we are using 2 pack Deco XE75 Pro, the available bandwidth of satellite Deco XE75 pro would be lower than 1G/s without an Ethernet conenction. The powerline adapter is still worth a try.

The BE65 is also a good choice if you are preparing for WiFi 7.

Thank you very much and best regards.
