Hi, and thanks in advance,

I hard-powered down my mac mini (2012) while it was booting up, and since then, osx has been unable to connect to any wifi networks. It sees the networks, and asks for passwords if appropriate, but fails to connect. When using windows via bootcamp, I'm able to connect to wifi perfectly, so I assume something is corrupted in my OSX settings.

Steps I've tried already (that have been unsuccesful):

Upgrading OSX to Catalina (interestingly, this resolved the issue immediately after upgrade, but it then went back to not working, perhaps a clue?)
Deleting preference files from the library and restarting
Deleting wifi from the network preferences page
creating a new OSX account

I'm pretty suck at this point, any help would be greatly appreciated.

Thanks again

I am having the same problem. I have Mojave and need to stay there because of software I need. I called the internet provider and went to the same steps. It keeps telling me I need to be closer to the router. I have a Mac mini and am as close as I can be. Do you have a solution? The provider gave me another profile on their modem and it doesn't work either.

I brought an Ethernet cable and hooked it my 2014 mac mini. I had to use printer cable to book up my printer. My android tablet and smartphone can connect through Wi-Fi with no problem. I used 25 foot CAT 5s for Ethernet.

OK, thanks for the additional information.

-Who is your ISP?
-Brand/model of router?
-What type of Wi-Fi security - WEP, WPA/WPA2, etc?
-Do you have  > System Preferences... > Security & Privacy > Firewall enabled?
-Any antivirus or other third-party utilities running at login?
-Are date & time correct on your Mac?

Let us know and we'll go from there.

No worries, still having the issue for the most part, though it now just takes a while (5-20 minutes) to connect. While connecting it displays the errors regarding password, etc.

Hello again,

-What errors is it displaying regarding password?
-You could try deleting the entries in Keychain Access. Only delete the entries that have the name of your Wi-Fi network.

OK, thanks.

Sometimes WEP causes issues with Macs and Wi-Fi. WPA is much more compatible and newer, and has pretty much replaced WEP across most manufacturers because of its better encryption and security. The Wi-Fi Alliance officially retired WEP in 2004.

Does the mini work normally with the Ethernet cable? If so, can it just remain connected that way, or is the run too far to the modem?

Maybe try deleting the entries for your network in System Preferences.. > Network > Wi-Fi and Applications > Utilities > Keychain Access.
