The current firmware allows the maximum transmission unit to be changed if needed. If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc). What is my MTU? - To find the proper MTU Size, you?ll have to do a special ping of the destination you?re trying to go to. A destination could be another computer, or a URL. Step 1 Click on Start and then click Run. Step 2 Windows 95, 98, and ME users type in command (Windows NT, 2000, and XP users type in cmd) and press Enter (or click OK). Step 3 Once the window opens, you?ll need to do a special ping. Use the following syntax: ping [url] [-f] [-l] [MTU value] Example: ping yahoo.com -f -l 1472 You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network we?re working with (1452+28=1480). Once you find your MTU, you can now configure your router with the proper MTU size. Note: AOL DSL+ users must use MTU of 1400. To change the MTU rate follow the steps below: For the DI-514, DI-524, DI-604, DI-614+, DI-624, DI-754, DI-764, DI-774, and DI-784: Step 1 Open your browser, enter the IP address of your router (192.168.0.1) and click OK. Step 2 Enter your username (admin) and password (blank by default). Click OK to enter the web configuration page for the device. Step 3 Click on the Home tab and go to the WAN tab. Step 4 The default MTU is 1500, to change this enter the number in the MTU field and click the Apply button to save your settings. Step 5 Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in increments of ten. Note: If you have the European version of the DI-604, this procedure will not work. If you do not have an MTU option, please upgrade your firmware.

Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony, VPNs, and others. These applications have difficulties working through NAT (Network Address Translation). If you need to run applications that require multiple connections, specify the port normally associated with an application in the Trigger Port field, select the protocol type as TCP (Transmission Control Protocol, UDP (User Datagram Protocol), or both, then enter the public ports associated with the trigger port to open them for inbound traffic. The Trigger port is an outgoing port (from LAN to WAN) that the application will send out. Step 1 Open your web browser and enter the IP address of your router (192.168.0.1). Step 2 Enter your username (admin) and password, if any. Step 3 Click on Advanced tab on the top and then Applications on the left side. Name - This is the name referencing the special application. Trigger Port - This is the port used to trigger the application. It can be either a single port or a range of ports. Trigger Type - This is the protocol used to trigger the special application. Public Port - This is the port number on the WAN side that will be used to access the application. You may define a single port or a range of ports. You can use a comma to add multiple ports or port ranges. Public Type - This is the protocol used for the special application. At the bottom of the screen, there are already defined well-known special applications. To use them, click on the edit icon and enable the service.

D-Link Air lets you access your network from anywhere you want. However, keep in mind, that range is limited by the number of walls, ceilings, or other objects that the wireless signals must pass through. Typical ranges vary depending on the types of materials and background RF noise in your home or business. The key to maximizing range is to follow these basic principles: 1. Keep the number of walls and ceilings to a minimum - Each wall or ceiling can rob your D-Link Air Wireless product of 3-90 ft. of range. Position your Access Points, Residential Gateways, and computers so that the number of walls or ceilings is minimized. 2. Be aware of the direct line between Access Points, Residential Gateways, and Computers - A wall that is 1.5 feet thick, at a 45 degree angle, appears to be almost 3 feet thick. At a 2-degree angle it looks over 42 feet thick! Try to make sure that the Access Point and Adapters are positioned so that the signal will travel straight through a wall or ceiling for better reception. 3. Building Materials make a difference - A solid metal door or aluminum studs may have a negative effect on range. Try to position Access Points, Residential Gateways, and Computers so that the signal passes through drywall or open doorways and not other materials. 4. Make sure that the antenna is positioned for best reception by using the software signal strength tools included with your product. 5. Keep your product away (at least 3-6 feet) from electrical devices that generate RF noise, like microwaves, Monitors, electric motors, UPS units, etc. 6. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your wireless connection will degrade dramatically or drop completely. Anything using the 2.4Ghz frequency will interfere with your wireless network. For the average home, range should not be a problem. If you experience low or no signal strength in areas of your home that you wish to access, consider positioning the Access Point in a location directly between the Residential Gateways.

The following is for the DI-514, DI-524, DI-604, DI-614+, DI-624, DI-624S, DI-754, DI-764, DI-774, and DI-784 routers. To perform a reset, please follow steps below: Step 1 With the unit on, place a paper clip into the hole on the back on the unit labeled Reset. Step 2 Hold paper clip down for 10 seconds and release. Note: Do not repower unit during this procedure. Step 3 The unit will reboot on its own. Once the WLAN light stops blinking, the unit is reset. Resetting the router does not reset the firmware to an earlier version. It will change all settings back to factory defaults. If you have the European version of this router, this procedure may not work. Please consult the D-Link office near you. D-Link USA does not support the European version.

You will need to get the IP address from your computer that you want to open ports to. Step 1 Open your web browser and enter the IP address of your D-Link router (192.168.0.1). Enter username (admin) and your password (blank by default). Step 2 Click on the Advanced tab at the top and then click Firewall on the left side. Step 3 Click on Enabled and type in a name for the new rule. Step 4 Choose WAN as the Source and enter a range of IP addresses out on the internet that you would like this rule applied to. If you would like this rule to allow all internet users to be able to access these ports, then put an Asterisk in the first box and leave the second box empty. Step 5 Select LAN as the Destination and enter the IP address of the computer on your local network that you want to allow the incoming service to. This will not work with a range of IP addresses. Step 6 Enter the port or range of ports that are required to be open for the incoming service. Step 7 Select Always for the Schedule or specify a range of Day and time that you would like this rule to be active. Step 8 Click Apply and then click Continue. Because our routers use NAT (Network Address Translation), you can only open a specific port to one computer at a time. For example: If you have 2 web servers on your network, you cannot open port 80 to both computers. You will need to configure 1 of the web servers to use port 81. Now you can open port 80 to the first computer and then open port 81 to the other computer.

Step 2 Enter your username (admin) and your password (blank by default). Click OK . Click the Home tab and click the Wireless button on the left hand side of the screen. Step 3 Select Enable next to the WEP radio buttons. For WEP encryption select 64, 128, or 256-bit encryption. For the Key type select HEX. If you have an option for Authentication type, select Shared Key. Step 4 Select Key 1. Enter a Hex encryption key that you make up. The length of the encryption key will depend on what you selected under WEP Encryption. 64-bit encryption 10 characters 128-bit encryption 26 characters 256-bit encryption 58 characters (available on DI-614+ only) The encryption key is HEX, meaning 0-9 and A-F are valid characters. For example, A4583DFF1A (64-bit HEX key). Step 5 Click on the Apply button then click on the Continue button to save your settings. Note: If using non-D-Link adapters, please refer to the manufacturer´s documentation on enabling encryption.

Make sure you disable or uninstall any PPPoE software such as WinPoet, Broadjump, or Enternet 300 from your computer or you will not be able to connect to the Internet. Do not disable until you´ve downloaded the firmware in Step 1. Please make sure that your modem is not also a router. If it is or you do not know, please contact your ISP and change the modem to Bridge mode. Note: In some areas, BellSouth and Verizon may not use PPPoE. Step 1 Upgrade to the latest firmware. Step 2 Take a paperclip and perform a hard reset. With unit on, use a paperclip and hold down the reset button on the back of the unit for 10 seconds. Release it and the router will recycle, the lights will blink, and then stabilize. Step 3 After the router stabilizes, open your web browser (Internet Explorer, Netscape, etc), enter 192.168.0.1 into the address window, and hit the Enter key. When the password dialog box appears, enter the username admin and leave the password blank. Click OK. If the password dialog box does not come up repeat Step 2. Note: Do not run Wizard. Step 4 Click on the WAN tab on left-hand side of the screen. Select PPPoE. Step 5 Select Dynamic PPPoE (unless your ISP supplied you with a static IP address). Step 6 For Earthlink users, under the username field enter ELN/username@earthlink.net and your password, where username is your own username (some Earthlink users may not need the ELN/ in front of username). For SBC Global users, enter username@sbcglobal.net. For Ameritech users, enter username@ameritech.net. For BellSouth users, enter username@bellsouth.net.** For most other ISPs, enter username. **Note: In some areas, BellSouth may not use PPPoE. Ameritech users: If you cannot connect, try entering just the username (without the @ameritech.com) and then put ameritech.net in the Service Name box. Step 7 Maximum Idle Time should be set to zero. Set MTU to 1492, unless specified by your ISP, and set Autoreconnect to Enabled. Note: If you experience problems accessing certain websites and/or email issues, please set the MTU to a lower number such as 1472, 1452, etc. Contact your ISP for more information and the proper MTU setting for your connection. Step 8 Click Apply. When prompted, click Continue. Once the screen refreshes, unplug the power to the D-Link router. Step 9 Turn off your DSL modem for 2-3 minutes. Turn back on. Once the modem has established a link to your ISP, plug the power back into the D-Link router. Wait about 30 seconds and log back into the router. Step 10 Click on the Status tab in the web configuration where you can view the device info. Under WAN, click Connect. Click Continue when prompted. You should now see that the device info will show an IP address, verifying that the device has connected to a server and has been assigned an IP address.

Note: Not all D-Link routers, print servers and access points have a web-based configuration utility. Please check the manual for your particular product. In particular, the DWL-900AP does not have a web utility while the DWL-900AP+ does have a web utility. You cannot gain web-based configuration utility functionality for the DWL-900AP by installing the DWL900AP+ utility. When entering the IP address of the D-Link device (192.168.0.1 for example), you are not connecting to a website on the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility. Make sure you have Java enabled and are using an updated web browser. We recommend the following: Internet Explorer 5.5 or higher Netscape 6 or higher Mozilla 1.2.1 (5.0) or higher Opera 6.0 or higher Safari 1.0 or higher (with Java 1.3.1 or higher) Camino 0.7 or higher Firefox 0.8 or higher -------------------------------------------------------------------------------- Internet Explorer 6 (SP1) users: If you continue to receive Error 500 when trying to connect to the web-based configuration of your D-Link device, make sure you have the latest Windows update for Explorer 6. -------------------------------------------------------------------------------- If you have Windows XP or Server 2003, you must download the latest Java patch from www.java.com. Click here to download patch - http://www.java.com/en/download/index.js... To resolve difficulties accessing a D-Link model that has a web utility, please follow the steps below. Step 1 Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on. What type of cable should I be using? - http://support.dlink.com/faq/view.asp?pr... Step 2 Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, and Windows XP firewall may block access to the configuration pages.

Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults. Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Nothing should be checked. Click OK. Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK out to the desktop and close any open windows. Step 4 Check your IP address. Your computer must have an IP address in the same range of the device you are attempting to configure. Most D-Link devices use the 192.168.0.X range. Click here to find your IP Address on your computer - http://support.dlink.com/faq/view.asp?pr... If you are attempting to configure a D-Link router, then make sure you take note of your computer´s Default Gateway IP address. The Default Gateway is the IP address of the D-Link router. By default, it should be 192.168.0.1. If you are attempting to configure an Access Point or Print Server, you may need to configure your computer with a Static IP Address in the appropriate range. Click here to set a static IP address on your computer - http://support.dlink.com/faq/view.asp?pr... Step 5 Access the web management.
