Rehabman-
Thank you for all of the guides and work you've put into making Hackintoshes available to the masses. And thanks in advance for your help with my issue.
I have Sierra loaded on my 840 G3, and have been trying to get my BCM94352Z (Lenovo flavor- if that matters) to work properly. I can connect to my local wifi and it works, but the best it can manage for speed is like dial up. I spent a couple of days tinkering with my previous install of Sierra on it before finally deciding it had to be something with the install, so I wiped it last night and rebuilt from scratch. Problem is, my wireless speed is still like using dial up.
Attached are the requested problem reporting files. I have a unique issue with the built in ethernet on this laptop that may be related to this wifi issue. The ethernet runs great, and at normal speeds. The thing is, for ethernet to work I must boot the laptop with the ethernet cable connected if I want to use it. If I disconnect and reconnect the ethernet after it has been booted (and working) OR if I connect the cable after the laptop has booted it will never obtain an IP address. The symptoms I see as I observe SysPrefs->Network as it obtains an IP is it will report the ethernet as connected but no IP, it then appears to reset and says the ethernet is disconnected, then goes back to ethernet connected but no IP. It will sit in this loop infinitely. If I reboot the laptop and don't change any physical connections it will work. My laptop has the I5-6300U processor which should mean it has the I219-V ethernet card. I'm running your IntelMausiEthernet kext.
I'm sure this problem is the result of something stupid I've done. Thanks for your time reviewing my wall of text and attached files.
