    hi guys

    its painful that after upgrading from yosemite to Sierra my wifi card is missing. (Wi-Fi: No hardware installed)

    Tried resetting the SMC or PR reset still the same.

    Any ideas?

    Sounds like your Mac is a 4,1 (flashed 5,1) that has an unsupported Wi-Fi card.

    Not many choices, you may downgrade to El Capitan, or upgrade your Wi-Fi card.
