D-Link COVR X1860 a1

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

The D-Link COVR-X1860 are MT7621-based AX1800 devices (similar to DAP-X1860, but with two Ethernet ports and external power supply) that are sold in sets of two (COVR-X1862) and three (COVR-X1863). Current openwrt support is being worked on in: https://forum.openwrt.org/t/add-support-for-d-link-covr-x1860/161862/55

Write a short, relevant description of the device. Include a technical overview, but avoid marketing buzzwords/useless stuff. Two to four sentences is about right. A picture is good, too. Edit the page to see how to add pictures.

Generic Router

Not supported.

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

Option 1: recovery mode (simple, requires chromium-based browser and paper clip or similar)

  1. Install a Chromium-based browser on the PC (Chrome, Edge, etc.)
  2. Download recovery firmware image
  3. Connect router and computer with a LAN cable (plug into one of the two LAN port on the COVR-X1860)
  4. Set the IP of the PC to and subnet mask to
  5. 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)
  6. Open the Chromium browser on the PC and enter the IP in the URL

Option 2: web interface (update menu)

  1. use factory install image (which is signed correctly)
  2. Connect router and computer with a LAN cable (plug into one of the two LAN port on the COVR-X1860)
  3. Login to the web interface with the password “password”
  4. move through the UI jungle for first config
  5. enter Management → upgrade
  6. upload factory image (browser should not matter here, but chromium is recommended)
