I bought these to extend wifi via AiMesh with my ASUS RT-AX86U router, which does really well already, but has difficulty getting strong signals to my garage and sunroom because they are add-ons and are outside the original house walls which have the aluminum backed insulation boards = almost no signals get in or out.
I placed one device in garage and sunroom at the closest wall outlet possible. The router signal was weak, but present.
Setup is simple, but not necessarily straightforward. I recommend using Asus router app with AiMesh if you can.
Plug device in wall VERY near router. Go through setup instructions. Once synced, move to desired location outlet and wait/watch for proper signal acquisition with lighting.
***I will note here that even when testing the devices throughout the house on other outlets where router signal was strong, they didn't want to connect. KEEP TRYING!! I had to unplug and plug several times.
Now, I have strong seamless signal in all areas and even 20-40 ft beyond house walls.
Pros:
-relatively simple setup
-good price
-plugs directly in wall outlet (no cords)
-very good wifi extension range
-seamless transition throughout areas with AiMesh
Cons:
-once plugged in, no room for 2nd plug in wall outlet
-devices pair well originally when very close to router, but then seemingly have difficulty reaquiring signal when moved elsewhere, even where signal is strong (keep trying!)
