What kind of authentication is usually affected by network issues?

Certificate-based authentication is typically affected by network issues because it requires a reliable connection for the exchange of certificates between the client and the server. This method relies on digital certificates for verifying identities and establishing secure connections. If there are network disruptions, such as latency or packet loss, the communication necessary to validate these certificates may fail, leading to authentication problems.

In contrast, other methods such as WPA2 Personal authentication, Open system authentication, and Static IP authentication do not inherently depend as heavily on continuous network conditions. For example, WPA2 requires a shared secret that is used for validation, and the process can often complete even with minor network issues. Similarly, Open system authentication is generally straightforward and less impacted because it does not involve complex exchanges of information. Static IP authentication relies on predefined network configurations and is not as sensitive to real-time network conditions.
