Current Status: Likely NOT Supported (No Official Image)
There is no evidence that the device w1700k (likely a router or embedded board) has an official OpenWrt firmware image or is listed in the Table of Hardware.
To get a definitive answer, you need to check two things:
-
Check the OpenWrt Table of Hardware:
-
Identify the actual chipset: "w1700k" sounds like a custom model number (possibly from brands like Banana Pi, FriendlyARM, or a generic industrial board). Look for the CPU model (e.g., Rockchip RK3588, MediaTek MT7986, Qualcomm IPQ8074). OpenWrt support depends on the SoC, not the board name.
If you find it is supported, typical features would include:
- Linux kernel 5.15 or 6.1+
- Fully writable filesystem with package manager (opkg)
- Firewall, QoS (SQM), ad-blocking, VPN (WireGuard, OpenVPN)
- Mesh networking (802.11s), VLANs, traffic shaping
- LuCI web interface and SSH access
If you cannot find official support:
- You may need to build your own firmware using the OpenWrt Image Builder or compile from source if the SoC is supported.
- Check forums or GitHub for community builds for that specific board.
Recommendation: Provide the brand and full model name (e.g., "Banana Pi W1700K" or "XYZ W1700K") or open the device and note the main CPU chip markings for a precise answer.

1. The Starting Point: Powerful Hardware, "Useless" Software
The W1700K launched as a cutting-edge WiFi 7 access point provided by Quantum Fiber (Lumen/CenturyLink). While the hardware was top-tier for its time, the user experience was severely restricted:
Locked Down: Users could not configure basic settings like guest networks, port forwarding, or band separation without using a mandatory mobile app.
Software "Mess": Technicians often spent hours trying to get the stock software to function, and users reported significant issues with privacy, security, and even basic connectivity for devices like the PS5.
Elite Specs: Despite the software flaws, the hardware was irresistible to enthusiasts, featuring an Airoha AN7581 quad-core processor, 2GB of DDR4 RAM, 512MB of Flash, dual 10GbE ports, and BE19000 tri-band WiFi 7 capabilities. 2. The Breakthrough: Serial Access and Rooting
Enthusiasts quickly realized that the device actually ran a heavily customized version of OpenWrt under the hood. This sparked a race to "liberate" the hardware:
Finding the UART: Developers discovered hidden TTL serial pins on the board (TX-GND-3.3V-N/A-RX).
Gaining Root: By interrupting the bootloader and entering failsafe mode, users were able to set a new root password and enable SSH access, bypassing the restrictive "Quantum" interface. 3. The Current Chapter: OpenWrt Liberation
As of early 2026, the W1700K has become a favorite target for the OpenWrt community.
Full Support: Active development on the OpenWrt GitHub has added support for the W1700K to the Airoha target.
