NRadio C8-668GL is a Wi-Fi 6 5G cellular router based on MediaTek MT7981B SoC. - **SoC**: MediaTek MT7981B (2x Cortex-A53, 1.3GHz) - **RAM**: Nanya NT5AD512M16C4-JR 1GB DDR4 - **Flash**: ESMT FC51L08SFY3A 8GB eMMC - **Ethernet**: - 1x 2.5GbE (via GMAC0 and GPY211 PHY, shared with MT7531AE) - 3x 10/100/1000 Mbps (via MT7531AE, connected to GMAC0) - 5G Modem: GMAC1 (via GPY211 PHY - RTL8125BG - RM520N-GL) - **Wi-Fi**: MediaTek MT7976CN (2.4GHz/5GHz, 802.11ax, 2x2 MIMO, AX3000) - **Buttons**: Reset, WPS - **LEDs**: Power, 5G, 4G, WiFi - **SIM Slot**: 1x Nano SIM - **5G Modem**: Quectel RM520N-GL (Snapdragon™ X62) - **Power**: 12V/2A DC, 5.5×2.1 connector The MAC addresses are derived from the `fac_mac` field in the `bdinfo` partition, formatted as `fac_mac = HWMAC`. The allocation is as follows: | Vendor | OpenWrt Interface | Address | Notes | |---------|-------------------|---------------|------------------------------------------------| | LAN | br-lan | Label MAC | Default | | WAN | lan4 | Label MAC+1 | Only when lan4 is switched to WAN | | 2.4GHz | phy0-ap0 | Label MAC | | | 5GHz | phy1-ap0 | Label MAC | (Local Admin bit set) | | Modem | eth1 | Label MAC+2 | | 1. Log in to the router via `http://192.168.66.1`/. 2. Upgrade the official firmware to dual-system mode. 3. Select **Burn second system** and upload the `sysupgrade.bin` image. - Download the image from the OpenWrt build system or build it yourself using the OpenWrt buildroot. 4. Wait for 30 seconds and click **Switch system**. 5. The device will reboot and switch to OpenWrt. Set the U-Boot environment variable `boot_system=0` and reboot: ```bash fw_setenv boot_system 0 ``` Power off the router, hold the **WPS button**, and power it back on. 1. Rename the stock firmware file to **`recovery.bin`**. 2. Set your PC's Ethernet IP to **192.168.1.88** and connect it to the lan1 port on the router. 3. Run a TFTP server and place the `recovery.bin` file in its root directory. 4. Power off the router, press and hold the **Reset button**, and power it back on. 5. Release the Reset button when the TFTP server shows activity. 6. Wait for the router to flash the firmware and reboot automatically. - By default, `lan4` is part of `br-lan` and uses the label MAC address. - To query the RM520N-GL module, use the following command: ```bash cat /dev/ttyUSB2 & printf 'ATI\r\n' > /dev/ttyUSB2 ``` Signed-off-by: Yaoguang Bai <0xdeadc0de@badguys.club> Link: https://github.com/openwrt/openwrt/pull/17093 Signed-off-by: John Crispin <john@phrozen.org> |

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Sunshine!
Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
Run
make
to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
Related Repositories

different categories. All packages are installed via the OpenWrt package
manager called opkg
. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
