I want this, but 5GHz doesn't permeate the walls in my bedroom as well. :( I figured we'd be living in a dual-band world for quite some time.

Weren't mesh wireless networks made to help this issue?

Also 802.11aX is out soon, it will use 2.4/5ghz just with a bit more bandwidth on both, so you may want to just wait for that instead. (edit: looks to be maybe +25% or so more)

I had the exact same propagation issue as you. Fortunately, I found a solution that's both inexpensive and incredibly effective.

A drill bit for wood... for drilling through walls? Wat?
