Have you set up wireless networks in offices? What authentication methods did you use?

Yes, in practice, when setting up wireless networks in offices, several authentication methods are usually used to ensure security:

• WPA2-Enterprise with 802.1X — the most common method for corporate networks. Uses a RADIUS server for user authentication via login and password or certificates.
• WPA2-Personal (PSK) — a simple method using a shared password. Suitable for small offices but less secure.
• Certificate-based authentication — a more secure way where the device or user authenticates using a digital certificate.

Depending on security requirements and infrastructure, the appropriate method is chosen. For example, large companies prefer to use WPA2-Enterprise with centralized access management.
