Today, my MacBook Pro (mid-2012) running High Sierra has decided to fail to connect to the hot-spot from my phone which is located a few feet away. It claims this is due to an
Invalid password. I've verified that the password I've given it is the correct one for the network. A Linux machine in the same room is able to connect using that same password.
I've taken the steps recommended in this answer: removing the Wi-Fi service, rebooting, and re-adding the Wi-Fi service. That did not help. I changed the network password on both the Android and the Mac; this also did not help. I've also changed the Wi-Fi network and password since rebooting.
Edit: since posting my question I have been able to use the network for a while, and since then it has again stopped working. I've switched over to Ethernet, which seems to be functioning correctly so far.
How can I make the Wi-Fi go?
