## Wireless Setup

The Wireless Setup page contains the settings for the (Access Point) Portion of the DIR-685. This page allows you to customize your wireless network or configure the DIR-685 to fit an existing wireless network that you may already have setup.
Wi-Fi Protected Setup (Also called WCN 2.0 in Windows Vista) This feature provides users a more intuitive way of setting up wireless security. It is available in two formats: PIN number and Push button. Enter the PIN number that comes with the device in the wireless card utility or Windows Vista's wireless client utility if the wireless card has a certified Windows Vista driver to automatically set up wireless security between the router and the client. The wireless card will have to support Wi-Fi Protected Setup in either format in order to take advantage of this feature.
Wireless Network Name Also known as the SSID (Service Set Identifier), this is the name of your Wireless Local Area Network (WLAN). By default the SSID of the DIR-685 is "dlink". This can be easily changed to establish a new wireless network or to add the DIR-685 to an existing wireless network.
Wireless Channel Indicates which channel the DIR-685 is operating on. By default the channel is set to 6. This can be changed to fit the channel setting for an existing wireless network or to customize your new wireless network. Click the Enable Auto Scan checkbox to have the DIR-685 automatically select the channel that it will operate on. This option is recommended because the router will choose the channel with the least amount of interference.
Transmission (TX) Rates Select the basic transfer rates based on the speed of wireless adapters on the WLAN (wireless local area network).
WMM Select Enable to turn on QoS for the wireless interface of the DIR-685.
Enable Hidden Wireless Select Enabled if you would not like the SSID of your wireless network to be broadcasted by the DIR-685. If this option is Enabled, the SSID of the DIR-685 will not be seen by Site Survey utilities, so when setting up your wireless clients, you will have to know the SSID of your DIR-685 and enter it manually in order to connect to the router. This option is enabled by default.
Wireless Security Mode Securing your wireless network is important as it is used to protect the integrity of the information being transmitted over your wireless network. The DIR-685 is capable of 4 types of wireless security; WEP, WPA only, WPA2 only, and WPA/WPA2 (auto-detect)

WEP
Wired Equivalent Protocol (WEP) is a wireless security protocol for Wireless Local Area Networks (WLAN). WEP provides security by encrypting the data that is sent over the WLAN. The DIR-685 supports 2 levels of WEP Encryption: 64-bit and 128-bit. WEP is disabled by default. The WEP setting can be changed to fit an existing wireless network or to customize your wireless network.

Authentication - Authentication is a process by which the DIR-685 verifies the identity of a network device that is attempting to join the wireless network. There are two types authentication for this device when using WEP.
Open System - Select this option to allow all wireless devices to communicate with the DIR-685 before they are required to provide the encryption key needed to gain access to the network.
Shared Key - Select this option to require any wireless device attempting to communicate with the DIR-685 to provide the encryption key needed to access the network before they are allowed to communicate with the DIR-685.
WEP Encryption - Select the level of WEP Encryption that you would like to use on your network. The two supported levels of WEP encryption are 64-bit and 128-bit.
Key Type - The Key Types that are supported by the DIR-685 are HEX (Hexadecimal) and ASCII (American Standard Code for Information Interchange.) The Key Type can be changed to fit an existing wireless network or to customize your wireless network.
Keys - Keys 1-4 allow you to easily change wireless encryption settings to maintain a secure network. Simply select the specific key to be used for encrypting wireless data on the network.

WPA-Personal
Wi-Fi Protected Access authorizes and authenticates users onto the wireless network. WPA uses stronger security than WEP and is based on a key that changes automatically at regular intervals.

Cipher Type - The DIR-685 supports two different cipher types when WPA is used as the Security Type. These two options are TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard).
PSK/EAP - When PSK is selected, your wireless clients will need to provide a Passphrase for authentication. When EAP is selected, you will need to have a RADIUS server on your network which will handle the authentication of all your wireless clients.
Passphrase - This is what your wireless clients will need in order to communicate with your DIR-685, When PSK is selected enter 8-63 alphanumeric characters. Be sure to write this Passphrase down as you will need to enter it on any other wireless devices you are trying to add to your network.
802.1X - This means that WPA authentication will be used in conjunction with a RADIUS server that must be present on your network. Enter the IP address, port, and Shared Secret that your RADIUS is configured for. You also have the option to enter information for a second RADIUS server in the event that there are two on your network that you are using to authenticate wireless clients.

WPA2
Wi-Fi Protected Access 2 authorizes and authenticates users onto the wireless network. WPA2 uses stronger security than WEP and is based on a key that changes automatically at regular intervals.

Cipher Type - The DIR-685 supports two different cipher types when WPA is used as the Security Type. These two options are TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard).
PSK/EAP - When PSK is selected, your wireless clients will need to provide a Passphrase for authentication. When EAP is selected, you will need to have a RADIUS server on your network which will handle the authentication of all your wireless clients.
Passphrase - This is what your wireless clients will need in order to communicate with your DIR-685, when PSK is selected. Enter 8-63 alphanumeric characters. Be sure to write this Passphrase down as you will need to enter it on any other wireless devices you are trying to add to your network.
802.1X - This means that WPA2 authentication is used in conjunction with a RADIUS server that must be present on your network. Enter the IP address, port, and Shared Secret that your RADIUS is configured for. You also have the option to enter information for a second RADIUS server in the even that there are two on your network, which you are using to authenticate wireless clients.

WPA2-Auto This option allows the DIR-685 to have both WPA2 and WPA clients connected to it simultaneously.

## Network Setup

These are the settings of the LAN (Local Area Network) interface for the device. These settings may be referred to as "private settings". You may change the LAN IP address if needed. The LAN IP address is private to your internal network and cannot be seen on the Internet. The default IP address is 192.168.0.1 with a subnet mask of 255.255.255.0.
IP Address - IP address of the DIR-685, default is 192.168.0.1.
Subnet Mask - Subnet Mask of DIR-685, default is 255.255.255.0.
Local Domain Name (optional) - Enter in the local domain name for your network.

DNS Relay - When DNS Relay is enabled, DHCP clients of the router will be assigned the router's LAN IP address as their DNS server. All DNS requests that the router receives will be forwarded to your ISPs DNS servers. When DNS relay is disabled, all DHCP clients of the router will be assigned the ISP's DNS server.

DHCP Server
DHCP stands for Dynamic Host Control Protocol. The DHCP server assigns IP addresses to devices on the network that request them. These devices must be set to "Obtain the IP address automatically". By default, the DHCP Server is enabled on the DIR-685. The DHCP address pool contains the range of IP addresses that will automatically be assigned to the clients on the network.

DHCP Reservation
Enter the "Computer Name", "IP Address" and "MAC Address" manually for the PC that you want the router to statically assign the same IP to or choose the PC from the drop-down menu, which shows current DHCP clients.

Starting IP address The starting IP address for the DHCP server's IP assignment.
Ending IP address The ending IP address for the DHCP server's IP assignment.
Lease Time The length of time in minutes for the IP lease.

Dynamic DHCP client computers connected to the unit will have their information displayed in the Dynamic DHCP Client Table. The table will show the Host Name, IP Address, MAC Address, and Expired Time of the DHCP lease for each client computer.

## LCD Setup

The LCD Setup page controls the settings of the display panel on your DIR-685 device. This page allows you to control the screen saver and adjust the amount of time the device needs to be idle before the LCD Screen turns off.
Screen Saver Setting - The screen saver will display the "screen_bg.jpg" picture stored in the root directory of the internal hard drive in the background, with the current date and time moving randomly above the picture. If this picture cannot be found, the background will remain black. The "Timeout" setting indicates the amount of minutes required before the device enters screen saving mode, if left idle. The device will exit screen saver mode if any button on the Touch Pad is pressed.
Display Setting - This setting will turn off the LCD display screen to save power if the device is left idle for the amount of minutes configured in the "Timeout" field. The LCD display screen will power on again if any of the Touch Pad buttons are pressed.
