56 Wireless configuration
Re-Key Interval
When using 802.1X dynamic WEP keys, enter the interval at which the router refreshes the keys
for each associated client. Specify a value in the range of 60 to 86400 seconds.
Configuring WPA and WPA2 security
Wi-Fi Protected Access (WPA) was introduced as an interim solution for the vulnerability of
WEP, replacing WEP encryption with TKIP. WPA2 includes the complete wireless security
standard (802.11i) and offers backward compatibility with WPA, but uses the stronger AES-
CCMP encryption. Both WPA and WPA2 provide an “enterprise” and “personal” mode of
operation. The “personal” WPA Pre-Shared Key mode uses a common password phrase for
user authentication that is manually entered on the router and all wireless clients. The
“enterprise” mode of WPA and WPA2 uses IEEE 802.1X for user authentication and requires a
RADIUS authentication server to be configured on the wired network. WPA2 is more secure
than WPA (TKIP) or WEP, therefore HP recommends to select WPA2 for maximum possible
security.
WPA2
The enterprise mode of WPA2 that provides the maximum security. You must set up at least one
configured RADIUS server in your network before enabling WPA2 security.
For RADIUS server settings, see “Configuring RADIUS settings” on page 59 .
WPA2 security includes the following settings:
Authentication Mode
Select
WPA2
to display all settings for WPA2 security.
Encryption Type
AES is the specified encryption for WPA2. All wireless clients must be capable of supporting
AES encryption to be able to associate with the router.
Group Key Interval
Enter the interval at which the broadcast (group) key is refreshed for clients associated with this
VAP interface (the default is 3600 seconds). The valid range is 60 to 86400 seconds. Specify
a value of 0 to disable the refreshing of broadcast keys.
