My D-Link router DI-624 locked up,Follow these steps to solve the problem:

• A large amount of traffic may lock the router up. Disable any broadcast protocols or unused protocols such as NetBEUI and IPX/SPX.

• Disable UPnP(TM) if not being used on both your computer (ME or XP) and on the router (Tools – Misc).

• Check the log on your router. Is it showing a large amount of traffic? If coming from 1 IP address, you may want to use the IP Filter to block that user.

• Check the log settings and uncheck some of the items the router will report.

• Check your firewall and virtual server settings on the router. Too many may degrade performance of the router.

• Upgrade firmware. If you have the latest version, flash it again.

• Perform a hard reset on the router and reconfigure. With the unit powered on, use a paperclip and hold down the reset button for 10-15 seconds. Release and wait about 20 seconds. DO NOT power off while holding the reset button.

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.

This article tell you how to use the special applications feature on D-Link routers,DI-624 as an example.

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.

This FAQ 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.

Nortel Contivity will work with the your D-Link router, however its functionality depends on the authentication type (AH will not work), NAT compatibilty mode, and disabling keep alives on the server. Contact your Network Administrator to find out how your VPN is configured.

Step 1: Verify that you are using the latest version of firmware on your router.

Step 2: Login to the Web Management for your router by entering its IP address (192.168.0.1) in your web browser. The default username is admin, and the password is blank.

Step 3: Click the Advanced Tab to access the Virtual Server Settings. There is a list of pre-defined Virtual Server Rules towards the bottom of the page. Find the IPSec Rule. Click the pen and paper icon to edit its settings. Enable the rule, enter the IP address of the computer attempting to connect to the VPN in the Private IP field, then Apply the changes.

Step 4: Create a new Virtual Server entry. Name the Virtual Server, “NortelVPN“. Enter the IP address of the computer attempting to connect to the VPN in the Private IP field. For the Protocol Type, select Both. Enter 9550 for both the Public and Private Ports. Set the Schedule to always, then Apply the settings.

Step 5: Access the Tools Page, then click the Misc button. Disable IPSec Pass-through, then click Apply.

If the VPN Server is properly configured to work with clients behind NAT routers you should be able to connect to the VPN.

This article is for the DI-514, DI-524, DI-614+, DI-624, DI-624S, and DI-714P+ Wireless Settings.

1.How to change the preamble on my DI series wireless router?

Step 1: Open a web browser and type the IP address of the wireless router in the address bar (default is 192.168.0.1). Press Enter.

Step 2: The default username is admin (all lower case) and the default password is blank (nothing). Click OK.

Step 3: Click the Advanced tab and then click Performance to the left.

Step 4: Select Short or Long next to Preamble Type. If you experience lock-ups when transferring large files, then select Short preamble. You must also match your other wireless devices with the same preamble setting.

Note: The preamble defines the length of the CRC block for communication between the wireless access point and the roaming wireless network adapters. CRC (Cyclic Redundancy Check) is a common technique for detecting data transmission errors.

2.How to change the SSID on D-Link wireless router?

Step 1: Open your web browser and type the IP address of the router in the address bar. The default IP address is 192.168.0.1. At the login, enter your username (admin) and password (default password is blank).

Step 2: Click on the Home tab at the top of the configuration page and then click the Wireless button on the left side.

Step 3: Next to SSID, type in a new SSID.

The SSID (Service Set Identifier) is the workgroup name of your Wireless Network. All devices (access points, wireless routers, and wireless adapters) must have the same SSID to communicate on the Wireless Network. The SSID can be up to 32 numbers, letters, spaces, and dashes. Also, the SSID is case-sensitive.

Step 4: Click Apply and then click Continue to save your settings.

3.How to change the channel on DI series wireless router?

In the 802.11b/g (2.4Ghz) standard there are 11 channels (US) to choose from, all but three are overlapping channels. Channels 1, 6, and 11 are the only non-overlapping channels. The channels can be changed to avoid interference from other wireless devices that run on the 2.4 Ghz frequency range (I.E. 2.4Ghz cordless phones, bluetooth, and X-10).

Step 1: Open your web browser and type the IP address of the router in the address bar. The default IP address is 192.168.0.1. At the login, enter your username (admin) and password (default password is blank).

Step 2: Click on the Home tab at the top of the configuration page and then click the Wireless button on the left side.

Step 3: Select a channel from the drop-down menu. For best results, use channel 1, 6, or 11.

Step 4 Click Apply and then click Continue to save your settings.

The DMZ feature allows you to forward all incoming ports to one computer on the local network. The DMZ, or Demilitarized Zone, will allow the specified computer to be exposed to the Internet. DMZ is useful when a certain application or game does not work through the firewall. The computer that is configured for DMZ will be completely vulnerable on the Internet, so it is suggested that you try opening ports from the Virtual Server or Firewall settings before using DMZ.

Depending on the D-Link router models, divided into the following set of several.
