Configuring WPA-PSK Encryption Security

Wi-Fi Protected Access (WPA) is wireless security with far greater protection than WEP.

WPS-PSK (pre-shared key) uses encryption of a shared key as the starting point. WPA has a

significant advantages over WEP — an encryption key differing in every packet. It is extremely

difficult for hackers to read messages even if they have intercepted the data.

To enable WPA-PSK Encryption Security:

1.

Click the Wireless Settings a or g link in the main menu of the WGU624 wireless router.

2.

Select WPA-PSK.

Figure 4-9:

WPA-PSK Security Configuration

3.

For the Cipher Type, select AES or TKIP.

4.

Enter a Passphrase. The Passphrase can be between 8 and 63 characters. The default

Passphrase is

NETGEAR-ULTRA-G

.

5.

The default for the Key Update time is 0, which is unlimited. If you want to limit the key

Update period, select a value between 15 and 1800 seconds.

6.

Click Apply.

Configuring Advanced Wireless Settings

The advanced wireless settings are configured separately for the 802.11a and 802.11g protocols.

Default Advanced Wireless Settings

The default advanced wireless settings are shown in the table below.

Note:

These settings should work for most networks and should not be changed unless you have a

specific reason to do so.

Configuring Advanced 802.11a Wireless Settings

From the main menu, click Advanced a Wireless Settings to view the configuration menu shown

below.

Advanced 802.11a Wireless Settings

•

Enable SSID Broadcast — allow Broadcast of Network Name (SSID). If you disable

broadcast of the SSID, only devices that have the correct SSID can connect. Disabling SSID

broadcast nullifies the wireless network ‘discovery’ feature of some products such as

Windows XP.

•

Enable Super A Mode — if enabled, the Wireless Router will enable data compression, packet

bursting and large frame support.

•

Enable eXtended Range — eXtended Range (XR) technology provides significantly longer

range than basic 802.11 by maintaining connectivity when signals are made fainter when

passing through dense walls, floors, or other barriers. XR products require no additional

configuration and are fully interoperable with standard 802.11 technologies.

Note:

The XR feature is NOT available when the wireless mode is “108Mbps only”.

•

Transmit Power — Max, 75%, 50%, 25%, or Min. The default is Max.

•

Fragmentation Threshold — value can be from 256 to 2346. The default is 2346.

•

CRS/RTS Threshold — value can be from 256 to 2346. The default is 2346.

•

DTIM — from 1 to 5. The default is 1. DTIM stands for Delivery Traffic Indication Message.

This setting determines how often the Access Point's Beacon (Traffic Indication Message)

contains a DTIM. The DTIM tells client devices in power-save mode that a packet is waiting

for them. The default setting causes client devices using power-save mode to wake up. To

conserve battery power in client devices using power-save mode, increase the Data Beacon

Rate (DTIM) setting. However, setting the DTIM too high may cause a wireless client to lose

its network connection.

•

Wireless Card Access List — when the Trusted PCs Only radio button is selected, the

WGU624 checks the MAC address of the wireless station and only allows connections to PCs

identified on the trusted PCs list.

Configuring Advanced 802.11b/g Wireless Settings

From the main menu, click Advanced g Wireless Settings to view the configuration menu shown

below.

Note:

The XR feature is NOT available when the wireless mode is “108Mbps only” and “b only”.

•

Enable Adaptive Radio — the Adaptive Radio (AR) feature is an option that is available when

the wireless settings are switched to the Auto 108 mode. When enabled, the Auto 108 mode

slows the data rate down automatically to the standard 802.11g (11g or 11b) mode and operate

at 54 Mbps or below when it senses any other neighboring wireless networks that are using

adjacent wireless channels. It steps up to a maximum data rate of 108 Mbps when it senses that

no other neighboring wireless networks are using adjacent channels. NETGEAR 108 Mbps

Wireless Products provide minimum interference to neighboring networks, so the default

setting for the Adaptive Radio feature is set to “Disable”.

•

Transmit Power —Max, 75%, 50%, 25%, or Min. The default is Max.

•

Fragmentation Threshold — value can be from 256 to 2346. The default is 2346.

•

CRS/RTS Threshold — value can be from 256 to 2346. The default is 2346.

•

Preamble Mode — Automatic or Long. The default is Automatic. Most access points and

client adapters have a setting called Preamble Type — Short or Long. The default “Automatic”

will automatically pick Short or Long preamble type depending on the client capability.

•

DTIM — from 1 to 5. The default is 1. DTIM stands for Delivery Traffic Indication Message.

This setting determines how often the Access Point's Beacon (Traffic Indication Message)

contains a DTIM. The DTIM tells client devices in power-save mode that a packet is waiting
