Firmware Myths and Misconceptions

It's been a misconception and belief that firmware fixes problems experienced by users and customers. And it's always been a belief that the latest and greatest should be always be kept up to date This maybe true however it depends on the condition of the problem and what the most current release of firmware actually changes.

In some cases, having the newest feature could be handing however might not be supported by your networking environment or ISP. Research into the firmware change log and history needs to be taking by users before considering updating as well. As a grain of salt to keep in the back of your mind, "If it works, don’t fix it!"

Firmware Update Steps

For those doing firmware updates on DLink routers, use the suggested following process:
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.)

***Use the following browsers only***: Internet Explorer or Fire Fox. Chrome and other browsers may cause the FW download to become corrupt or may improperly handle the data causing the router to be come bricked.

3rd Party Security Software Configurations
  • Turn off all anti virus and firewall programs on PC.
  • Turn off all devices accept for one wired PC.


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. 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. It's highly recommended to set up the router from scratch if you are upgrading from v1.1x to v1.2x as this is a major change in FW and loading a saved configuration from file that was from a v1.1x save on to a v1.2x loaded FW has been known to cause some problems.
