WPA2 - Personal protects unauthorized network access by utilizing a set-up password. WPA2 can be enabled in two versions - WPA2 Personal and WPA2 Enterprise. “Personal” and “Enterprise” just refer to the two flavours of WPA and WPA2. Although not directly answering the question, I include it for interest. I don’t think there’s any meaningful difference in the security.įWIW, I’ve used WPA2 Personal on my Airport Extreme since I bought it, and no device has ever had problems connecting.Ĭonfession: I initially misread the question as being about the difference between Personal and Enterprise, and wrote this. In a nutshell, a WPA/WPA2 network will any network card that supports WPA or WPA2 to connect to it whereas a WPA2 only network locks out network cards that only support the newer standard. WPA is both forward and backward-compatible and is designed to run on existing Wi-Fi devices as a software download. The Wikipedia article cites a white paper from the Wi-Fi Alliance: This advanced protocol will not work with some older network cards. The later WPA2 certification mark indicates compliance with the full IEEE 802.11i standard. Some network cards can’t connect to WPA2 networks. I believe that WPA was the original WPA standard, and WPA2 was an improved version of it.
