People also ask, why won't my Mac recognize my wifi?
Make sure your Mac is within range of the wireless network. The Wi-Fi service may not be available in Network preferences. On your Mac, choose Apple menu > System Preferences, then click Network . After the network is available, try connecting again.
Why I can't connect to WIFI Even I know the password?
Try turning the card off and then on again to reset it — see Wireless network troubleshooter for more information. When prompted for your wireless security password, you can choose which type of wireless security to use. Make sure you choose the one that is used by the router or wireless base station.
