Supporting activities
To get OpenWRT support, a private key from the GPL tarball has been extracted, which is used to create firmware images, which can be flashed in the normal non-recovery mode. After this, hardware support for this device will be added. Custom builds and a patchset is available from the following forum thread
- OpenWrt forum thread: https://forum.openwrt.org/t/add-support-for-d-link-covr-x1860/161862
Installation
Installing OpenWrt
Option 1: recovery mode (simple, requires chromium-based browser and paper clip or similar)
- Install a Chromium-based browser on the PC (Chrome, Edge, etc.)
- Download recovery firmware image
- Connect router and computer with a LAN cable (plug into one of the two LAN port on the COVR-X1860)
- Set the IP of the PC to 192.168.0.10 and subnet mask to 255.255.255.0
- Using a pointed object such as a paper clip or SIM card tool, press the reset button on the bottom of the router while simultaneously plugging in the router (and holding for a few seconds). The cross at the top of the device will blink red, once the device entered recovery mode.
- Open the Chromium browser on the PC and enter the IP 192.168.0.1 in the URL
Option 2: web interface (update menu)
- use factory install image (which is signed correctly)
- Connect router and computer with a LAN cable (plug into one of the two LAN port on the COVR-X1860)
- Login to the web interface with the password “password”
- move through the UI jungle for first config
- enter Management → upgrade
- upload factory image (browser should not matter here, but chromium is recommended)
