Security Settings for Wireless Networks

Use the Wireless > Basic Settings > Security Settings page to configure security
for the selected wireless network. All devices on this network (SSID) must use the
same security mode and settings to work correctly. Cisco recommends using the
highest level of security that is supported by the devices in your network.
To open this page: From the Wireless > Basic Settings page, select a network
and then click Edit Security Mode.
To configure a network with WPA Enterprise, WPA2 Enterprise, or WPA2 Enterprise
Mixed security mode, you must first add a RADIUS Server configuration. See
the Cisco RV220W With a RADIUS Server, page
If needed, select a different network in the Select SSID list.
Enter these settings for the selected network:
• Wireless Isolation within SSID—Check Enable to prevent clients on this
wireless network from accessing devices on other wireless networks. To
allow access, click Disable.
• Security—Choose a security mode:
- Disabled—Any device can connect to the network. Not recommended.
- Wired Equivalent Privacy (WEP)— Weak security with a basic
encryption method that is not as secure as WPA. WEP may be required if
your network devices do not support WPA; however, it is not
recommended.
- Wi-Fi Protected Access (WPA) Personal—WPA is part of the wireless
security standard (802. 1 1i) standardized by the Wi-Fi Alliance and was
intended as an intermediate measure to take the place of WEP while the
802. 1 1i standard was being prepared. It supports TKIP/AES encryption.
The personal authentication is the Preshared Key (PSK) that is an
alphanumeric passphrase shared with the wireless peer.
- WPA Enterprise—Allows you to use WPA with RADIUS server
authentication.
- WPA2 Personal—WPA2 is the implementation of security standard
specified in the final 802. 1 1i standard. It supports AES encryption and this
option uses PSK based authentication.
- WPA2 Personal Mixed—Allows both WPA and WPA2 clients to connect
simultaneously using PSK authentication.
