OpenWrt enables software flow offloading by default. While this reduces CPU load during heavy routing, it also keeps the networking interrupt handlers in a constant state of readiness. On the W1700K, this generates a steady thermal floor of 5-10W of heat.
6GHz Wi-Fi is functional in some builds but may require specific security settings (WPA3-SAE). Current Issues:

The upcoming OpenWrt 24.00 release includes a new ( thermald ). This will allow the W1700K to dynamically throttle only when hitting 80°C, rather than the crude "all or nothing" system currently used. Early builds show a 20% improvement in thermal efficiency. w1700k openwrt hot

OpenWRT is a Linux-based open-source firmware that is designed to replace the stock firmware of routers. It offers a high degree of customization, allowing users to tailor their router to their specific needs. With OpenWRT, you can add or remove features, modify the user interface, and even create your own plugins and scripts. This level of flexibility makes OpenWRT a popular choice among advanced users and developers.

Transforming Your BenQ W1700K into a Smart Home Hub with OpenWrt
: Despite some early jitter issues, many now use it as their primary router with "rock stable" performance. Advanced Features
Stand the router vertically if possible to allow hot air to escape more easily. 6GHz Wi-Fi is functional in some builds but
If you are a networking novice looking for a "plug and play" experience, this is likely not the router for you. But if you are a hobbyist, a student on a budget, or someone who loves the idea of turning "e-waste" into a high-performance network node, the W1700K is currently one of the most exciting devices on the market.
Set the download and upload speeds to roughly 90% of your total internet bandwidth.
) has exploded in popularity across the OpenWrt Community . Originally distributed by Quantum Fiber as a locked-down residential Wi-Fi 7 gateway, massive batches of these premium devices flooded online secondary markets following AT&T's acquisition of Quantum Fiber. Selling for a fraction of its manufacturing cost, networking enthusiasts quickly realized its true value: it features top-tier capabilities, a powerful Airoha AN7581 SoC , 2GB of RAM , and dual 10GbE ports .
