Android 11, PEAP 'could not connect' to WiFi

[spahr8]

Hi All,

We have the following infrastructure for unmanaged Android 11 phones used by our staff:

Windows Server NPS Server
Configured with Cisco WAPs as RADIUS Clients

NPS Network Policy (PEAP) using server-side public CA certificate to create a secure TLS tunnel to protect user authentication.
eap type: secured password (EAP-MSCHAP v2)

From an Android 11 Phone
Tap the wireless SSID and manage
Enter PEAP, MS-CHAPv2
domain:FQDN of public CA Certificate wireless.domain.com.au

Error: Could not connect.

Has anyone else come across this issue and managed to resolve?

Thanks

I work in the networking field and own a P4 running android 11. You need to know the network domain. The easiest way to find this at school is to log into a machine and right click on the network connection, open network and internet settings. It should show the domain. If not, then open a Command Prompt and type ipconfig. The "Connection-Specific DNS Suffix" will be the domain, make sure that whole name is in the "domain" section of the login. Before Android 11, I never had to input the domain.
