Additionally, compatibility issues may be cumbersome because of the variety of authentication methods 
supported and the lack of a standard implementation method. 
Therefore, IEEE 802.1x mode is not as secure a solution as Wi-Fi Protected Access (WPA) or WPA2. If, 
you cannot use WPA because some of your client stations do not have WPA, then a better solution than 
using IEEE 802.1x mode is to use WPA Enterprise mode.

Security Settings”. 
When to Use WPA Personal 
Wi-Fi Protected Access Personal Pre-Shared Key (PSK) is an implementation of the Wi-Fi Alliance IEEE 
802.11i standard, which includes Advanced Encryption Algorithm (AES), Counter mode/CBC-MAC 
Protocol (CCMP), and Temporal Key Integrity Protocol (TKIP) mechanisms. This mode offers the same 
encryption algorithms as WPA2 with RADIUS but without the ability to integrate a RADIUS server for 
user authentication. 
This security mode is backwards-compatible for wireless clients that support only the original WPA. 
 
Key Management 
Encryption Algorithm 
User Authentication 
WPA Personal provides 
dynamically- generated keys that 
are periodically refreshed. 
There are different Unicast keys 
for each station. 
  Temporal Key Integrity 
Protocol (TKIP) 
  Counter mode / CBC-MAC 
Protocol (CCMP) Advanced 
Encryption Standard (AES) 
The use of a Pre-Shared (PSK) 
key provides user authentication 
similar to that of shared keys in 
WEP. 
 
Recommendations 
WPA Personal is not recommended for use with the AT-TQ2403 Management Software when WPA 
Enterprise is an option. 
We recommend that you use WPA Enterprise mode instead, unless you have interoperability issues that 
prevent you from using this mode. 
For example, some devices on your network may not support WPA or WPA2 with EAP talking to a 
RADIUS server. Embedded printer servers or other small client devices with very limited space for 
implementation may not support RADIUS. For such cases, we recommend that you use WPA Personal.

When to Use WPA Enterprise 
Wi-Fi Protected Access Enterprise with Remote Authentication Dial-In User Service (RADIUS) is an 
implementation of the Wi-Fi Alliance IEEE 802.11i standard, which includes Advanced Encryption 
Standard (AES), Counter mode/CBC-MAC Protocol (CCMP), and Temporal Key Integrity Protocol 
(TKIP) mechanisms. This mode requires the use of a RADIUS server to authenticate users. WPA 
Enterprise provides the best security available for wireless networks.
