unable to connect to network after Windows 11 22h2 update

Peter E Lewis 46

I performed the Windows 11 22h2 update today and it updated successfully. However, I am no longer able to connect to my schools internet. I am able to connect to my schools guest internet but not the student one. I've run the trouble shooter, but it hasn't been helpful. Is this an issue with the update or my schools internet. If it is a problem with my schools internet is there some way that I could uninstall the update (I am unable to do it through settings) so that I could go back to when it did work?
Thank you!

It takes me 2 weeks to finally get the correct method to fix this for 22H2 and 2x go back to previous version until i figured out what's the issue.

The culprit is TLS version which in 22H2 case went up to version 1.3. What you can do is to force the TLS version to 1.2. Here's how to do it:

Open Registry Editor

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RasMan\PPP\EAP\13

Create DWORD key TlsVersion value FC0

Logout and re-login, you should be able to connect to your school internet now.

We have run into this issue as well. The quick fix as we receive this issue is for the customer to forget the SSID (our 802.11 we use is eduroam) and re-connect to the SSID

This one worked for me.

I could connect to any other network but not to my college's network after I updated to 22H2 this morning.
Besides I was able to connect from Linux with no problem, so it was a W11 update issue.

Ok, tried this, but didn't work for me. What I found was that Credential guard is enabled by default in 22H2, and only disabling this resolved the issue on our network.

I also took two days to upgrade Windows 11 22H2 then restore 21H2.
I observed that the root cause of connecting failure is NOT support automatically use windows logon name and password (and domain if any) when authenticaion.

You could try to generate the WiFi report by the following command.
netsh wlan show wlanreport

OMG I'VE JUST SOLVED IT, I've been trying solutions for 4 weeks, try this:

First, forget the wifi and reset the network settings>network&internet>advanced network settings>network reset after restart ur PC
Secondly, the Control panel>network and sharing centre>set up a new connection or network>manually connect to a wireless network>network name (this should be the exact name capitals and signs are essential)>security type: WPA2-Enterprise>next>change connection settings>security>settings>verify the server's identity by validating the certificate (this must be unselected)> click ok and click advanced settings>specify authentication mode select>user authentication>okay>okay>close
Finally, try to connect and write ur username and password

Let me know if its works :)
I am still using the last version of windows btw

If you block outgoing traffic, it now needs the dns udp port 53 to identify the network. Add a custom outoing firewall rule for UDP port 53 - the predefined windows rules won't work.

Tried the below-mentioned steps. Still facing the same issue.

Open Registry Editor

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RasMan\PPP\EAP\13

Create DWORD key TlsVersion value FC0

I have a similar problem. A brand new Laptop with Windows 11 installed.
One router will connect but the other router tries to connect with same WiFi key then after about 20 seconds reports "Unable to connect"
What is the actual script I would use for "Create DWORD key TlsVersion value FC0"?

Bom dia,

Verifiquei que o problema foi gerado devido a atualização para windows 11 22h2, com a conexão wp2-enterprise, o AD não aparece tentativa de login, dando erro.

Solução desativa serviço device Guard

###### WINDOWS CONEXÃO NO WIFI-WP2 Enterprise DEPOIS DA ATUALIZAÇÃO 22H2 ######## * Abra o Power Shell(ADM) * gpedit.msc * Politica Computador Local > Comfiguração do Computador > Modelos Administrativos > Sistema > Device Guard * Ativar Segurança Baseada em Virtualização - Desativar

Para facilitar criei uma GPO no AD para os grupo de notebooks novos.

Por favor dei o ok se deu bom?

I too was having issues with my wpa2-enterprise network once I upgraded to 22h2, on a brand-new laptop with all current updates and drivers installed. Tried all the registry options above, but did not do anything. My magical fix was to reset the wireless profile, and I had to put the username in the "Your Private Identifier" field. If I didn't put anything or kept the default entry "anonymous" in it, NPS would interpret the Account name as Guest or Anonymous and wouldn't be able to authenticate. Even when I entered my valid credentials when prompted, it would still put Guest or Anonymous in the account name until I placed the username in the Private Identifier field.
