Question: The wifi network requires a WPA2 password - 2018

I've experienced this problem on both my MacMini and my MBP running Mojave and previously on my MPB running High Sierra.

The Mac would not connect to a WIFI access point, claiming the wifi network requires a WPA2 password.

This was very annoying as :

a) the wifi had worked previously

b) the access point was working with other devices, e.g. my Android tablet and phone

c) the password was correct, as I could view the access point through my MacMini's wired ethernet connection.

There's a lot of advice on this problem and it's been persistent. I tried all of the usual suggestions without any success:

  • Forget the WIFI network, remove it from System Preferences - then reboot
  • Delete Spaces preferences in the Library folder - then reboot
  • Rebooted the WAP/router
  • Change the WIFI password on the router

But then I found the solution.

Open System Preferences / Network / WIFI / Advanced / TCP/IP and then click the Renew DHCP Lease.

The wifi instantly connected.

I hope this helps some with this annoying issue.


PS I'm on Mojave 10.14.2 and so this may not work on other MacOS versions but it's worth a try.
