Fallback feature. Auto-Fallback will automatically negotiate the best possible connection speed between the

Access Point and a wireless device.

Access Point VLAN ID

. Enter the VLAN ID of the Access Point. Make sure this matches at least one of the VLAN

IDs listed in the aforementioned table.

Wireless Channel

. Select the appropriate channel from the list provided; this will be the channel that all of your

wireless devices will use.

Wireless SSID Broadcast

. This feature allows the main SSID to be broadcast by the Access Point. You may want

to enable this function while configuring your network, but make sure that you disable it when you are finished.

With this enabled, someone could easily obtain the SSID information with site survey software and gain

unauthorized access to your main network. Click

Enabled

to broadcast the main SSID to all wireless devices in

range. Click

Disabled

to increase network security and block the main SSID from being seen on networked PCs.

NOTE:

You must use the Access Point VLAN ID for one of your wireless networks in order to

maintain access to the Access Point’s Web-based Utility.

NOTE:

Only the main SSID of the Access Point can be broadcast. The Access Point cannot

broadcast any of its Virtual SSIDs.

Wireless Security

Enter the security settings for each SSID of the Access Point.

Select SSID

. Select the SSID whose security settings you want to configure.

Security Mode

. Select the security method you want to use,

WPA-Personal

,

WPA-Enterprise

,

RADIUS

, or

WEP

.

(WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands

for Wired Equivalent Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) Refer to the

appropriate instructions below. For detailed instructions on configuring wireless security for the Access Point,

turn to “Appendix B: Wireless Security.” To disable such security, select

Disable

.

WPA-Personal

Allow PCs with the same wireless network name (SSID) to see each other

. When enabled, devices in the

same wireless network will be able to access each other, so they can transfer files through the network. To deny

access, select

Disabled

. Otherwise, keep the default,

Enabled

.

WPA Algorithms

. WPA offers you two encryption methods, TKIP and AES, with dynamic encryption keys. Select

the type of algorithm you want to use,

TKIP

or

AES

.

WPA Shared Key

. Enter a WPA Shared Key of 8-32 characters.

Key Renewal Timeout

. Enter a Key Renewal Timeout period, which instructs the Access Point how often it

should change the encryption keys.

or

128 bits (26 hex digits)

.

Passphrase

. To generate WEP keys using a Passphrase, then enter the Passphrase and click the

Generate

key.

Key 1-4

. If you want to manually enter WEP keys, then complete the fields provided. Each WEP key can consist of

the letters “A” through “F” and the numbers “0” through “9”. It should be 10 characters in length for 64-bit
