on NPS - do the following:

Choose 802.1X connection from drop down in main menu (see picture)
Give the connection a name
create Radius Clients for all APs - with correct shared key
Select EAP type - for establishing connection to NPS server. Try with Protected EAP first
Choose configure - choose certificate and choose EAP type, try MS-Chap V2 - clients authenticating using usernames and passwords
Select User Groups that are granted access, depending on how you want to grant access, to computers, users or both ...

nps start
Here's some good step-by-step guide

you can use a special windows group if you want only a few users to have access, or you can use domain computers/users ---

That document covers some - but it uses EAP-TLS (Certificate and smart card) for inner authentication - but says nothing on how to deploy certificates to users and computers.
It doesn't say anything on how to deploy RAS/IAS certificate to NPS server.

For start - it would be easier to deploy MsChapV2 as inner authentication method rather than EAP-TLS - to avoid enrolling certificates to all clients

Otherwise it looks okay

if it's not domain joined - then you should deploy a user group and either certificates (export and import to user computer) or user EAP-MsChap V2 - and remove Use Windows Login Credentials;
