In certain cases you may wish to downgrade router firmware to an earlier version if the manufacturer released an unstable version, or a new version removes functionality you prefer to keep access to. As such we've documented below how to do this:
First you’ll need to gain an internet connection - this can be done in a few ways:
- Either by connecting a laptop or PC directly to the ONT (fibre modem) on the wall, in the same port as your router would normally use.
- Or, if your router is currently online you can connect through that in the standard fashion.
- Alternatively you may be able to use a mobile device on data, if your device can also support extracting files and uploading them to the D-Link.
Next you want to visit this web-page: D-Link Technical Support and download the Firmware version 1.20B06 (this is their last full stable release). You’ll then want to extract this and it should give you a file called: DIR_882_FW120B06.BIN
Then we’ll want to login to the D-Link page (by entering 192.168.0.1 in your web browser’s address bar). After this we can go to Management > Upgrade and we’ll see the below:
Ensure the Automatic Upgrade is disabled. After this just hit the “Select File” button, and select the DIR_882_FW120B06.BIN file we downloaded earlier and press “Upload”:
This should bring it back online and allow you to connect reliably again - though in some cases the quick setup may need to be run again in case the downgrade didn’t quite keep all settings.
