Hello,

Currently I have a BCM94352Z (DW1560) in my hack, that runs perfect. I can connect via Wifi+BT, iMessage works, Handoff, etc.

I noticed shortly after installing Sierra that my Wifi Speeds have dropped. When I visit SpeedTest.net my max speed is around 30Mb/s. When tested on my Macboook Air (Early 2015)...I get around 100Mb/s.

I can confirm that I am connecting via 802.11ac to the router. I have reset the router and modem many times but with no changes.

How can we go about diagnosing this problem?
