The Quantum Fiber W1700K is a high-performance Wi-Fi 7 gateway that has gained significant traction in the OpenWrt community due to its impressive hardware being available at a low cost. While it officially runs a customized version of OpenWrt from the factory, that version is heavily locked down and unmanageable by end-users. Solid Hardware Features
The standout "solid feature" of this device is its enterprise-grade hardware specifications, which are rarely found in consumer units at its current second-hand price point:
Networking: Dual 10 GbE and dual 1 GbE LAN ports, making it one of the cheapest 10-gigabit capable routers for OpenWrt enthusiasts.
Processor: Airoha (MediaTek subsidiary) AN7581GT Quad-core 1.3 GHz ARM processor.
Memory & Storage: 2 GB DDR4 RAM and 512 MB NAND flash, providing ample headroom for complex OpenWrt packages and configurations.
Wireless: Tri-band Wi-Fi 7 (2.4GHz, 5GHz, and 6GHz) with 320 MHz channel support and 4x4 MU-MIMO.
Extras: Built-in GPS chip for AFC (Automated Frequency Control) to enhance 6GHz range, and an IoT radio supporting Bluetooth 5.1, Zigbee, and Matter. OpenWrt Status and Considerations While the hardware is "solid," the OpenWrt support for the Go to product viewer dialog for this item. is currently in a state of rapid transition: Official Support: As of early 2026, the
has been moved to "official" status in OpenWrt, meaning SNAPSHOT images are starting to be built.
Installation Difficulty: Installing standard OpenWrt currently requires a high level of technical skill. It often involves opening the unit and soldering to access the TTL serial console (UART) pins for initial flashing via TFTP.
Performance: Once flashed, users report "rock stable" Wi-Fi and excellent routing performance, though some features (like the full NPU offloading) may still be seeing refinements in community builds. Where to Buy
Because these are primarily distributed as ISP-rented equipment for Lumen/Quantum Fiber, they are most commonly found on the secondary market:
Used/Resale Sites: Retailers and sites like eBay often have these units listed for $30-$60, which community members on Reddit consider an exceptional value for the specs. Quantum Fiber W1700k support - Page 69 - For Developers
The Ultimate Guide to the Quantum Fiber W1700K and OpenWrt The Quantum Fiber W1700K (also known as the Gemtek MXF-W1700K) is a high-performance Wi-Fi 7 gateway provided by ISPs like CenturyLink and Quantum Fiber. While it is a formidable piece of hardware out of the box, advanced users often seek to install OpenWrt to unlock its full potential, bypass ISP restrictions, and gain access to advanced networking features. Hardware Overview: A Wi-Fi 7 Powerhouse
Before diving into the firmware, it is essential to understand why this device is a prime candidate for OpenWrt. The W1700K features top-tier specifications that rival many high-end consumer routers:
CPU: Quad-core Airoha AN7581 (ARM Cortex-A53) clocked at 1.3 GHz.
Memory: 2 GB DDR4 RAM, which is significantly higher than most consumer routers, allowing for extensive package installations. Storage: 512 MB NAND Flash. Ethernet Ports: 2x 10GbE (WAN/LAN). 2x 1GbE LAN.
Wireless: Tri-band Wi-Fi 7 (BE19000 class) supporting 2.4GHz, 5GHz, and 6GHz bands with MLO (Multi-Link Operation) capabilities. Why Install OpenWrt on the W1700K? w1700k openwrt
The stock firmware on the W1700K is often described as "unmanageable" because it is designed to be remotely configured by the ISP via an app. By flashing OpenWrt, you gain:
Full Control: Access a comprehensive web interface (LuCI) to manage every aspect of your network.
Enhanced Features: Install over 3,500 packages, including VPNs (WireGuard/OpenVPN), ad-blockers (AdGuard Home), and advanced QoS (SQM).
Stability & Security: Regular community updates that often outlast official manufacturer support.
Hardware Optimization: Recent OpenWrt builds allow for overclocking and improved UDP throughput. OpenWrt Support Status (2026 Update) [OpenWrt Wiki] Gemtek MXF-W1700K (Quantum Fiber W1700K)
Unlocking the Full Potential of the Quantum Fiber W1700K with OpenWrt The Quantum Fiber W1700K (also known as the Gemtek W1700K

The Gemtek W1700K (also branded as the Quantum Fiber 360 Wi-Fi 7 Pod Go to product viewer dialog for this item.
) is a powerful Wi-Fi 7 mesh node that has gained significant traction in the OpenWrt community due to its high-end hardware and low cost on the used market.
As of April 2026, the device is officially supported in OpenWrt snapshot builds. Hardware Overview
features top-tier specifications for a Wi-Fi 7 access point: Processor: Airoha AN7581 (1.3 GHz, quad-core ARM). Memory/Storage: 2 GB RAM and 512 MB Flash. Connectivity: 2x 10GbE Ethernet ports and 2x 1GbE LAN ports. Tri-band Wi-Fi 7 (BE19000) using MediaTek MT7996AV.
Other: Active cooling (internal fan) and Bluetooth 5.1/Zigbee support. Installation Status & Method The Quantum Fiber W1700K is a high-performance Wi-Fi
Standard installation requires serial console access, as the stock firmware is locked down and does not support third-party upgrades through its web interface.
Access Serial: Requires opening the case (Torx T10 screw under the label) and connecting to the UART header (TX-GND-VCC-N/A-RX).
Unlock Bootloader: The stock U-Boot is configured to only run signed images. Users must interrupt the boot sequence to modify environment variables (e.g., bootcmd) to allow booting OpenWrt.
Flash OpenWrt: Typically involves booting an initramfs image via TFTP and then using sysupgrade to flash the final image. Current Capabilities & Issues
While officially supported, some features may still be experimental:
Wi-Fi 7: The 6GHz band and high-speed Wi-Fi performance are functional in recent builds.
10GbE Support: Support for the 10G ports requires specific drivers (RTL8261N), which are integrated into the main OpenWrt branch.
LEDs & Fan: Earlier issues with non-working LEDs and uncontrolled fans have mostly been addressed in "Lumos" or "Minimal" community patches, but the stock red-light status may persist in older snapshot versions. Where to Find More
Official Builds: Available via the OpenWrt Table of Hardware or the Firmware Selector.

The Gemtek MXF-W1700K (distributed by Quantum Fiber as the W1700K) is a high-performance Wi-Fi 7 router that has gained significant attention in the OpenWrt community. While the stock firmware is often locked and difficult to manage, its hardware makes it an exceptional candidate for a custom OpenWrt installation. Hardware Specifications
The W1700K features powerful networking hardware typically found in much more expensive enterprise gear:
Processor: Airoha AN7581 (a subsidiary of MediaTek), which is natively supported by newer OpenWrt kernels. Memory: 2 GB of RAM. Storage: 512 MB NAND Flash.
Ethernet Ports: 2x 10GbE (1 WAN, 1 LAN) and 2x 1GbE LAN ports.
Wireless: Tri-band Wi-Fi 7 (BE19000 class) supporting 2.4 GHz, 5 GHz, and 6 GHz bands. Part 8: Is It Worth It

Since “W1700K” is not a widely documented retail model, I’ll assume it refers to an IPQ8074-based router/AP (e.g., Dynalink DL-WRX36, Xiaomi AX9000, or similar Wi-Fi 6 boards used in industrial/ODM designs). OpenWrt support for IPQ8074 is mature in the Snapshots (23.05+) and upcoming 24.10 releases.
Yes – 100%. The W1700K running OpenWrt is one of the best value routers in 2025.

Final Pro Tip: Once you are stable, compile your own OpenWrt image using the mediatek/mt7981-w1700k target in the source code. This lets you remove unused drivers (bluetooth, NFC) and bake in your SSH keys. You'll boot in under 10 seconds.
The Linksys WRT series (specifically the WRT1200AC, WRT1900ACS, and WRT3200ACM) holds a special place in the networking community. While the WRT1900AC v1 had radio issues that made OpenWrt support difficult, the WRT1900ACS and the rebranded WRT1700ACS (often found in European markets) are widely considered the "sweet spot" for a reliable, high-performance OpenWrt router.
