May Flash bluetooth signal best on which product?

[NightMover]

I have a Magic NS 1. I find that when I get around 3 meter away the signal can stop reaching my Wii U pro controller to work properly even unobstructed .

Also, it won’t work through a wall when my apple mouse does fine.

Is there a way to strengthen the signal with another product?

Or does anyone know if the signal would be stronger with either the

MAYFLASH Magic-S PRO 2​

Or another one of their products?

I use a 8 bit do adapter and a DS4 and it works fine anywhere across my average size appartement. I don't see myself living without it I highly recommend.
