Unlike many other wireless router with same SoC selling in China, this one doesn't have U-boot locked. Thus installing OpenWrt becomes much easier comparing to other competitors.

We will utilize the U-boot recovery mode to flash the OpenWrt.

1. Restore the route to factory default unless it's a brand-new opened box.
2. Disconnect the power cable.
3. Connect the route to a laptop/desktop with a ethernet cable on LAN port.
4. Set IP address on the laptop /desktop to 192.168.1.11 with Netmask as 255.255.255.0, Gateway as 192.168.1.1
5. Insert the power cable and QUICKLY press the RESET button in rear panel.
6. If previous step was done properly, two LEDs on the routing will be blinking. That's a sign for recovery mode.
7. Type 192.168.1.1 in the Web browser address bar.
8. On recovery Web page, select the downloaded OpenWrt bin file.
9. Click flash and wait.
10. Meanwhile, you may want to restore the IP settings on laptop/desktop to Automatic(DHCP)

NOTE: The similar procedure may be used to restore to stock firmware.

Flashing through TFTP doesn't seem to work right now.

→ Basic configuration After flashing, proceed with this.

The 802.11AC, or 5G wireless capability is provided kmod-mt76 package. It may be installed via terminal

 opkg update && opkg -y install kmod-mt76

Or through LuCI Software page.

After rebooting, the LuCi will present the 5G network in Wifi page.
