W1700k Openwrt -

The "story" of the Gemtek W1700K (distributed as the Quantum Fiber WiFi 7 Pod) is a journey from a locked-down, service-provider-controlled device to a high-performance, community-liberated powerhouse.

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.

Custom Builds: Projects like "Lumos" and various community builds (e.g., from OpenWRT-fanboy) provide optimized firmware that enables the 6GHz radio and works toward full 10GbE driver stability.

The Result: Flashing OpenWrt transforms a "pretty useless" ISP pod into a high-performance, multi-gigabit router capable of nearly 1Gbps speeds over WiFi everywhere in a home with significantly improved latency.

It took some digging through the OpenWrt forums, but seeing that LuCI dashboard on this hardware is so satisfying. If you've got one of these sitting around, it’s time to flash it. #OpenWrt #QuantumFiber #Networking #W1700K A few things to keep in mind:

Minimal Images: As noted in recent forum discussions, many users are starting with "minimal" builds to fit the initial patchsets.

Bricking Risk: Always remind readers that flashing ISP-provided hardware can be tricky and may void terms of service.

The Gemtek W1700K (Quantum Fiber WiFi 7 Pod) is a high-performance tri-band router featuring an Airoha AN7581 SoC, 2GB of RAM, and 512MB of flash. While powerful, the stock firmware is highly restricted, making OpenWrt a popular choice for unlocking its full potential.

Warning: This process requires opening the device, using a serial console, and modifying bootloader variables. It is intended for advanced users and will void your warranty. Prerequisites

Hardware: A USB-to-TTL Serial Adapter (3.3V) and a Torx T10 screwdriver.

Software: A TFTP server (like tftpd64) and a terminal emulator (PuTTY or Screen).

Files: You need the initramfs-uImage.itb and the sysupgrade.itb files. Recent community builds are often hosted on GitHub or the OpenWrt Forum. Step 1: Serial Console Access

Open the case: Remove the Torx T10 screw hidden under the QR code on the label. Use a pry tool to separate the white and gray plastic.

Connect UART: Locate the 5-pin header. From left to right (starting near the screw hole): Pin 1: TX (Connect to RX on adapter) Pin 2: GND (Connect to GND)

Pin 3: VCC 3.3V (DO NOT CONNECT – this can damage your adapter or router) Pin 4: N/A Pin 5: RX (Connect to TX on adapter). Chapter 5: Living on the Edge – Maintenance

Terminal Settings: Set your serial software to 115200 baud, 8N1. Step 2: Backup Stock Firmware (Recommended)

Before making changes, it is highly recommended to back up your original partitions.

Power on the router and press f then Enter when prompted for failsafe mode. Run mount_root and change the password with passwd.

Modify /etc/config/axon_platform_manager to enable SSH by setting sshServerEnable, localAccessEnable, and remoteAccessEnable to 1.

Reboot, SSH into the device, and use dd to save all /dev/mtdX partitions to your computer. Step 3: Modify Bootloader Variables You must instruct U-Boot to allow unsigned images.

Interrupt the boot process by pressing any key when "Hit any key to stop autoboot" appears. Enter the following commands exactly:

setenv bootflag 0 setenv one "flash read 0x600000 0x1000000 $loadaddr" setenv two "; bootm" setenv bootcmd "$one$two" setenv one setenv two saveenv Use code with caution. Copied to clipboard

Note: This allows booting from flash using a manual address rather than the signed vendor command. Step 4: Load OpenWrt via TFTP Set your computer's static IP to 192.168.0.205.

Place the openwrt-...-initramfs-uImage.itb file in your TFTP server folder. In the U-Boot console, run:

tftpboot 0x89000000 .itb bootm 0x89000000 Use code with caution. Copied to clipboard

Note: The Ethernet driver can be flaky during this stage; you may need to try the tftpboot command several times if packets are dropped. Step 5: Permanent Installation

Once the router boots into the OpenWrt "Live" environment (RAM): Access the LuCI web interface at 192.168.1.1. Navigate to System -> Backup / Flash Firmware.

Upload the sysupgrade.itb file to write OpenWrt permanently to the flash memory. Current Known Issues LEDs: May stay red or not function correctly.

10G Ports: Driver support is still evolving; they may require specific kernel patches to work as intended.

Fan Control: The fan typically runs at a constant speed and is not yet dynamically controlled in most builds. Quantum Fiber W1700k support - For Developers

Chapter 5: Living on the Edge – Maintenance

Never opkg update – full package lists won’t fit. Instead:

Pre-download .ipk files to a USB drive (if router has USB) or serve from a local HTTP server.
Install with: opkg install --force-depends /tmp/mypackage.ipk

To save overlay space:

# Move log to RAM
echo 'tmpfs /var/log tmpfs defaults,noatime,nosuid,size=64k 0 0' >> /etc/fstab
mount /var/log

Rebuild with new settings: Never save config on device – maintain it externally in files/etc/config/ and rebuild image each time.

3. Expand Storage (USB Mod)

The W1700K has a USB 3.0 port (if your variant includes it). Use it for extroot.

Plug in a USB drive (ext4 format).
Install block-mount and kmod-usb-storage.
Copy rootfs to USB: mount /dev/sda1 /mnt ; cp -a /overlay/* /mnt
Update /etc/config/fstab to boot from USB.
Result: You now have unlimited space for packages.

1. Enable the MediaTek Hardware Offloading

The MT7981B has a hardware packet processor (HQoS). Without offloading, the CPU will max out at 300Mbps. With offloading, you'll route 940Mbps+ on Gigabit LAN.

SSH into the router: ssh root@192.168.1.1

Edit /etc/config/firewall:

config defaults
    option flow_offloading '1'
    option flow_offloading_hw '1'

Restart firewall: /etc/init.d/firewall restart
