Menu System 9

Channel drop-down menu lets you change the radio channel for the wireless communication. This

is useful if you experience poor performance that could be as a result of interference from other

wireless devices.If Auto is selected, the router will automatically determine which channel it should

select.

Bandwidth drop-down menu will be enabled whenever 802.11b+g+n or 802.11n is selected as the

Wireless Band. By default, 20MHz is selected as it ensures the best compatibility with client

devices. When selecting 40MHz, a second channel is enabled which can increase throughput for

compatible 802.11n which also support 40MHz. Please note that by selecting 40MHz, you might

experience incompatibility with certain devices. In such case, please use 20MHz.

The 2nd Channel drop-down menu will be available once the Bandwidth has been manually set to

40MHz. From there, you can appoint the placement of the secondary channel to be located either

below or above the primary channel. Please note that when using 40MHz, the gap between two

bonded channel points is equivalent to 4 numbered channels. Therefore, if selecting channel 6, the

paired channel will either be 2 or 10, depending on your selection of placement.

Data Rate drop-down menu is the setting for the transmission speed at the selected Wireless

Band. If you experience problems at high data rates, then we recommend that you select a lower

data rate.

SSID (Service Set Identifier): is the name of the router that will appear in other Wireless LAN

clients when they perform a network search.

Default value is DOVADO

SSID Broadcast: enables or disables transmission of the SSID from the router.

When disabled, other Wireless LAN clients will not find the router when they perform a network

search.

Fragment length: is a setting that affects the quality of the wireless transmissions. If you

experience a high packet error rate you can decrease this value in small steps to reduce this

problem. Setting the fragment length too low may result in poor performance.

Default value is 2346.

RTS length: is a setting that affects the quality of the wireless transmissions. If you experience

inconsistent data flow you can decrease this value in small steps to reduce this problem.

Default value is Off.

Wireless Radio: enables or disables the WLAN. If you do not use any Wireless LAN devices it is

recommended that you select disable.

Click on Save WLAN Settings and then Restart for the changes to take effect.

3.5.2 Authentication

The encryption settings for your Wireless LAN.

Encryption is disabled by default. Choose Enable to show the available settings.

There are three main types of encryption methods in the Authentication Type dropdown menu,

which are WPA1/WPA2-PSK, WEP Shared Key and WPA1/WPA2-Enterprise.

WPA-PSK is the most secure, and therefore the best recommended method. Choose it from the

Authentication Type drop-down menu and then enter a pass phrase between 8 and 63 characters.

The key is case sensitive. All Wireless LAN clients must use the exact same pass phrase in order

to access your network. The absolute securest setting is to use WPA2 together with AES

ciphering; however, older devices might not support it.

If you have a device that does not support WPA-PSK authentication, then select WEP Shared Key.

Choose a Key Type, either HEX or ASCII. Then choose Key Size; 64 bits (for HEX this is 10

characters and for ASCII 5 characters) or 128 bits (for HEX this is 26 characters and for ASCII 13

characters): the longer the key, the stronger the encryption. The key is case sensitive. You have
