Question: what is the difference between wpa2 and wpa/wpa2?
Answer: WPA and WPA2 are two different protocols for WiFi connection and security. WPA uses TKIP as part of its security, while WPA2 uses AES, which provides much better protection. ... If you have to reduce security for some devices that cannot support WPA2, then the WPA/WPA2 option may be the option to use.
