@AlbionShrewwrote:
An engineer (sub-contractor?) visited and installed my new Halo3 Hub. Now connection throughout the house is worse. Beware!
There is no Halo3 hub, you would of received a Smart Hub 2 like all BB customers do now, try disabling the 5GHz band, 2.4GHz works fine for me in my small/average size house with around 20 devices connected.
