Thanks. We'll let you know when a new response is added.

The first widely used standard for wireless LANs was 802.11
(prime); this included the Wired Equivalent Privacy (WEP) algorithm
which was used for security. WEP utilizes RC4 for encryption and has been
depreciated because of vulnerabilities that can be used to find the security
keys.

In response to the vulnerabilities found in WEP, Wi-Fi
Protected Access (WPA)
 was defined. WPA utilizes the Temporal Key
Integrity Protocol (TKIP) which utilizes dynamic keys that were not supported
with WEP and RC4 for encryption. The TKIP method used with WPA was utilized
until vulnerabilities were found in TKIP. These vulnerabilities center on the
fact that TKIP uses some of the same mechanisms that WEP does which allow
similar attacks.

In response to the vulnerabilities in WPA/TKIP, the IEEE
802.11i standard was defined and implemented; the IEEE 802.11i standard is also
referred to as WPA2. WPA2 replaced TKIP with Counter Mode with
Cipher Block Chaining Message Authentication Code Protocol (CCMP) which is
based on Advanced Encryption Standard (AES); it is common for the WPA2
encryption method to be referred to as AES. As of this writing, there are no
easy methods that have been found to break AES.

    In general WPA2 is the basic reply. Whatever encryption method is using, it is necessary to careful of turn off remote access, DMZ/UPNP and of course unnecessary port forwarding. You have to gain knowledge on WEP/WPA/WPA2 etc. Please navigate here for more info: https://searchnetworking.techtarget.com/feature/Wireless-encryption-basics-Understanding-WEP-WPA-and-WPA2

    Are you asking what's the strongest that you might use? The strongest that has been implemented anywhere? Home user, business or government? Do you have a specific use case? A budget?

    Depending on what you need, most likely WPA2 with AES. Just remember, if you're using consumer-grade APs, you need to disable WPS or at least enable intruder lockout for WPS PINs. Otherwise, your encryption means nothing.
