Update
As it is working for some people and not for others I tried something.:
I downgraded to a previous build ( pac_amami_LP-MR1.Beta-2.UNOFFICIAL_20150718-210746.zip) ... Wi-Fi did work again. I then updated "dirty" back to your current build ( pac_amami_LP-MR1.Beta-3.Unofficial_20151009-093311.zip) and Wi-Fi is still working. Does that mean something is missing in the current version?
