Mojave can't connect to a WiFi with WPA2 Enterpreise

Hello,

I had the same issue to connect to a WPA2 Entreprise wifi (with a certificate) and Mojave .

The solution has been to change the locale of the os (😮 yes, i know!).

Steps :

- Go to Preferences -> Language & Région -> Add a new language (with the + icon) (be sure to put a language that you understand, as your os will then be set in that language)

- Make it the default one

- You should be asked to restart the mac.

- After the restart follow the standard procedure to connect to the wifi, it should work know...

Hoping it solves the problem for you too.

I have had this same issue at work. I upgraded to Mojave, attempt to log in with Active Directory credentials, and it fails to authenticate, in turn fails to connect to our WPA2 Enterprise WIFI. I contacted my admin, they said to downgrade back to High Sierra, so I did, and was able to authenticate and connect to our WIFI. Is there something blocking authentication through WPA2 Enterprise networks? or is there something else I should be trying? I have already tried some of the other suggestions. Resetting the P Ram didn't make a difference. It just seems to work with High Sierra, but something about Mojave has changed the way it reacts to WPA2 Enterprise networks.

It's odd that both devices can't connect to the Wi-Fi. My own Wi-Fi issues on my 2015 Macbook pro were solved with this here:

Reboot the Macbook, while starting press the key combination: Option + Command + R + P. You should hear the a sound twice while you see the Apple logo. If so, release the keys and login like always. All Wi-Fi networks should be working again 🙂

Greetings, Pedro.

I see that, since upgrading your iPhone X to iOS 12 and your MacBook Pro to macOS Mojave, neither device is able to connect to your school's Wi-Fi network. I'm happy to help.

Here are the articles you need. One for your iPhone, one for your Mac:

• If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network
• Check for Wi-Fi issues using your Mac

Take care!

Jkim,

I haven't had success getting iOS devices on the WPA2 Enterprise either. Some forums are stating it is a Certificate issue. Something in the newer Mac OSX and iOS is not liking the certificates. Since the majority of our company are on Android and Windows clients (and are all up and connected), the Admins do not believe there is anything wrong with WIFI. If you get anywhere with it, please let me know.

If Mojave is trying to connect to a wpa2 network with a portal popup login and it is being blocked, you could try typing the following url into your browser..

No meu agrupamento há duas escolas com configurações idênticas em termos de WiFi. Na escola pequena funciona tanto o MacBook como o iPhone e o iPad. Na escola maior nem sequer recebo indicação de que o certificado está expirado. Equipamentos Apple não conseguem autenticar-se, mas antes conseguiam. No caso do iPad nem sequer foi alteração de sistema, porque é um iPad 2 e já não tem atualizações desde o 9. Mas por outro lado continuo a conseguir autenticar com Windows 10 ou Android.

I had the same problem and reinstalled Mojave, which seems to have resolved things, for now....

Fingers crossed!

Hello.

I have the same problem with the Mojave 10.14 with wifi on the public (school) networks and have to downgrade to the High Sierra. (with the High Sierra in two schools networks lets install the certificate).

With the new version 10.14.1 will wifi works? In my case I always have an error and asked to contact the Administrator ...
Thanks

server authentication ;)

I have a MacBook Mojave and iPhone 12.1, they both work in one school, but not in the other school. The wifi specifications are the same in both schools. So, I think this is not a Mojave issue.

Sem atualização de sistema deixei de conseguir aceder com iPad 2 numa das escolas mas continuo a conseguir na outra. Não me parece ser uma questão de atualizações. Apostaria mais na sobrecarga de utilizadores (funciona na escola pequena e não na escola maior) mas não entendo porque só afeta produtos Apple.

Pelo que li na net e n testes que fiz na maquina tem a ver com a "politica" dos routers. Qualquer coisa de SSL`s

Lembro que li que a Apple "mexeu" em algumas coisas em acesso a redes wifi wpa2 por questões de "segurança".

Houve uma tentativa de ataques ao Routers...

Penso que como solução seria/pode ser preciso atualizar nos routers do Ministério ou alterar informações nessas redes. Estranho é dar com uns e outros não. Não sei se o Ministério da Educação estará dentro deste assunto.

Li que em máquinas mais antigas com o Mojave nem reconhecia o Airport, placa de rede wifi. Testei tudo.... Dá que pensar que com máquinas mais antigas não gostam do Mojave e com a compra de uma maquina nova seria o ideal...

Procurando no google "Mojave wifi issues" ha muita gente com problemas e soluções que testei e nada. Ainda hoje li que com este IOS 12.1.2 há muito problemas em ligações a redes wifi "normais"

Espero que com um novo update isto se solucione...

Abraço

Hey I'm sorry for the delayed response

I had to downgrade my operating system to Sierra (NOT high sierra) which worked for a little bit though it was finicky. I have to note though that after coming back from the holidays, the WiFi is again not working so I'm back to square one.

The minute that my laptop was able to connect, my phone was also able to connect which confused me given that they run on different operating systems from what I thought.

If I find a permanent (or more permanent solution) I'll definitely post here.
