Firmware Update Steps

Do NOT upgrade firmware on any D-Link product over a wireless connection. Failure of the device may result. Use only hard-wired LAN network connections.

1. Save the current routers configuration to file. Tools/System. (Note that reloading this onto new major version of firmware can cause problems and thus is recommended to configure the router from scratch. Do not load the old configuration file from the old major version. If you're upgrading from minor to minor version, reloading of the configuration file shouldn't cause a problem. In these cases, please do not upload the previous older configuration file, rather set up the router from scratch. Should you need the configuration information from the previous saved configuration file, capture, copy or write down all required information from the configuration file loaded on the router BEFORE applying the newer firmware update.)

NOTE:

For routers using the new web page UI:
Management -> System Admin -> System
Save Settings To Local Hard Drive

2. Factory reset the router using the routers web page Tools/System, is easiest, or the back button.

3. Update the router using the routers web page Tools/System using the .bin file(s) that was downloaded for your product model. The .bin files have to be unpacked from the .zip file.

4. After the router as updated and status has reported it was successful on the routers web page, power OFF the ISP modem/ONT for 30 seconds then power back ON the modem/ONT. Perform one more Factory reset of the router using the routers web page Tools/System.

5. After the router has reset and come back to ready, reload the saved configuration file or reconfigure the router from scratch and walk thru the set up wizard. Status LEDs should be Blue, Green or White for power and internet (Globe) the router unit depending on model.

NOTE:

Clear all browser caches before and after loading FW files. 

Important Notes:

1. DSR-500AC/1000AC product doesn’t support BGP routing and are not affected by the potential vulnerability that is well known as CVE-2004-0230, the attacker can potentially reset the BGP connection with the device.

2. All DSR routers with WW version are not allowed to install RU firmware image in order to prevent unnecessary misunderstanding for customers.

3. Before plug DWM-152/156 3G USB dongle in DSR-500AC/1000AC, please make sure the SIM Card is not set PIN code.

4. Microsoft Windows XP has some well-known limitation to access USB storage of DSR router, D-Link provides a Registry Script file named: WinXP.reg which can solve limitation of Windows XP environment. Without applying this script file, it cannot copy file from Windows XP to USB storage. (This issue will not happen when copy file from USB storage to Windows XP)

5. For any firmware downgrade situation, i.e. from a newer version to an older one, it will take more time to restart system comparing to firmware upgrade, i.e. from an older version to a newer one. If you MUST execute firmware downgrade for your own reasons, please allow DSR more time to reboot system.

6. To authenticate SSL VPN users through external databases including RADIUS, LDAP, AD and POP3, admin must also need to create user accounts with the same username and password in the local user database.

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn’t either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn’t be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don’t always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you’re looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don’t power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don’t miss the update that will improve your device.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
