Original Question:
This is a noob question.
I managed to boot High Sierra on my Acer Aspire E1-571-6854 but wifi was very slow (around 100kbps of download). After reading Dortania's guide of supported cards, I have seen that a BCM94322 is supported and was wondering if I would get good wifi speeds with it.
Current laptop specs:
CPU: I5 3230M
RAM: 6GB
GPU: HD 4000
Wifi card: AR5B125 (AR9485 chipset)
Install method: Opencore
Is it a good idea to buy a BCM94322?
