MacBook Pro won't connect to Wi-Fi, with correct password. Error: "The Wi-Fi network requires a WPA2 password" I'm trying to connect to my home Wi-Fi. When I enter the correct password, I get the message

The Wi-Fi network requires a WPA2 password

I verified the password is correct in my router configuration.
I am using a 2017 MacBook Pro, running macOS Mojave 10.14.2.
I restarted my modem/router combo, restarted my MacBook, tried removing the home Wi-Fi and re-adding it (under System Preferences → Networks → Advanced → Preferred Networks), and changed the Wi-Fi password. Nothing works. My Wi-Fi name (SSID) doesn't have any special characters either.
I have another 2015 MacBook Pro and an iPhone that can connect to my home Wi-Fi with no problems. So, it seems issue seems to be particular to this device (the 2017 MacBook Pro) in combination with my home network. This device has no problems connecting to other Wi-Fi networks (it works successfully at my office, at the airport, other homes, etc.)
How do I resolve it?
I just had the same issue.  The answer I found online said to go to system preferences, then network, then click advanced and then click TCP/IP and click the Renew DHCP Lease; but I don't think that did anything.

However, instead of clicking TCP/IP, stay on the Wi-Fi page (or go back to it by clicking the tab) and click the + button to add the network.  You need the network name and password, and for security I chose WPA2 personal.  Apply or Click OK and that should do it.  It worked for me and now I get connected automatically.
