According to the "D-Link DWL-8200AP User Manual", it states that the following wireless security methods are available:
- The method of authentication is similar to WEP because you define a "Pre-Shared Key" on the wireless router/AP. Once the pre-shared key is confirmed and satisfied on both the client and access point, then access is granted. The encryption method used is referred to as the Temporal Key Integrity Protocol (TKIP), which offers per-packet dynamic hashing. It also includes an integrity checking feature which ensures that the packets were not tampered with during wireless transmission
- WPA2-Personal is far superior to WPA-Personal, because the encryption of data is upgraded with the Advanced Encryption STandard (AES).
- WPA-Enterprise and WPA2-Enterprise is ideal for businesses that have existing security infrastructures in place. Management and security implementation can now be centralized on a server participating on the network. Utilizing 802.1x with a RADIUS (Remote Authentication Dial-in User Service) server, a network administrator can define a list of authorized users who can access the wireless LAN. When attempting to access a wireless LAN with either WPA_Enterprise or WPA2-Enterprise configured, the new client will be challenged with a username and password. If the new client is authorized by the administration, and enters the correct username and password, then access is granted.
- WPA2-Enterprise is far superior to WPA_Enterpirse, because the encryption of data is upgraded with the Advanced Encryption Standard (AES).
However, according to the "User's Guide - HP iPAQ hx2000 Series Pocket PC", page 8-3, under "Automatically Connecting to a Network", step 2 states "If you are prompted for a Network Key (WEP), enter it and tap Connect. If you are not sure, contact your network administrator." Even under the section "Manually Entering New Network Settings", step 11 states "To configure the type of network authentication to use, select: a. To use Shared Key authentication, tap the Authentication (Shared mode) listbox. Type the network key in the Network Key: box. b. To use data encryption, tap the Data encryption (WEP enabled) listbox. c. If a network key is provited by your network automatically, tape the The Key is provited for me automatically. 12. For increased security, tap the 802.1x tab and select the UseIEEE8021x network access control chekbox. You should only check this option if it is supported by your netowrk environment. Ask your network adminstrator if you are unsure."
In summary, it seems like the AP supports WPA and the iPAQ supports WEP. The D-Link DWL-8200AP supports "Shared Key" mode, however by solving that problem would result in creating at least two problems: 1) weakening of the D-Link DWL-8200AP wireless security and 2) Using WEP/Shared Key mode would render the RADIUS server useless.
I would like to recommend that you get another AP that is compatible with WEP and place it around where the PDA is most likely to be used. If the PDA is likely to be used anywhere on campus grounds, then you might need to implement a second network of WAPs for WEP capable units to use. To help maintain the security integrity of the D-Link DWL-8200AP in WPA-Enterprise mode, you might need to place the WEP WAPS on a VLAN of their own.
I hope this helps.
