Trying to keep your WiFi safe can feel confusing. There are a bunch of letters like WEP, WPA, WPA2, and WPA3 that show up when you look at your router settings. You might wonder what they all mean ...

However, as I learned from Fujitsu Technical Support, to get a Wireless-N connection above 54 Mbps, you have to use WPA2/AES security and encryption.

However, if you have old Wi-Fi devices that aren't compatible with WPA2, you can use the TKIP+AES or "mixed" mode option if it's available on your router.

Use WPA2-AES. It has the best security and throughput. There are scenarios where adding tkip decreases security, however it for sure increases compatibility with old crap.

A WPA compliant device however can implement AES optionally whereas WPA2 compliant devices must be capable of both though you're not required to use AES.
