W1700k Openwrt Hot ✓

Quantum Fiber W1700K is currently a "hot" topic in the OpenWrt community because it is high-end hardware (Wi-Fi 7) often provided for free by ISPs, but its stock firmware is severely locked down. Core Hardware Features The device is a beastly Wi-Fi 7 gateway/access point with the following internal specs: : Airoha AN7581GT. : 2GB RAM and 512MB Flash. : MediaTek MT7996 chipset supporting (tri-band Wi-Fi 7). : Two 10G ports (via Realtek RTL8261N) and two 1G ports. Additional : Integrated cooling fan (software controllable) and GPS capability. OpenWrt Forum OpenWrt Support Status (April 2026) Quantum Fiber W1700k support - Page 19 - OpenWrt Forum

Here’s a concise piece of technical documentation / troubleshooting note based on your keywords "w1700k openwrt hot" (likely referring to the Xiaomi Mi Router W1700K — also known as the AX3000 or similar Mediatec Filogic 820 platform — overheating under OpenWrt).

OpenWrt on Xiaomi W1700K: Overheating & Mitigation Issue: Users report the W1700K running abnormally hot (surface temps >65–70°C) after flashing OpenWrt, especially under load (WiFi + NAT + SQM). Root Causes:

Missing OEM thermal throttling – Stock firmware aggressively manages CPU/radio power; OpenWrt defaults to performance governor. Driver power draw – mt76 driver (MediaTek) on Filogic 820 may keep radios at higher tx power than stock. Passive cooling limits – Small heatsink, no fan, closed plastic case. w1700k openwrt hot

Check current temperature: cat /sys/class/thermal/thermal_zone0/temp # or awk '{printf "%0.1f°C\n", $1/1000}' /sys/class/thermal/thermal_zone0/temp

Solutions (apply via SSH / LuCI):

Switch to conservative governor echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Make permanent: add to /etc/rc.local Quantum Fiber W1700K is currently a "hot" topic

Reduce WiFi TX power (5 GHz especially) iw dev wlan0 set txpower fixed 1800 # 18 dBm iw dev wlan1 set txpower fixed 1800

Add a small USB fan under the router (5V, quiet) – drops temps by 10–15°C.

Consider recompiling OpenWrt with CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y and limiting max freq to 1.3 GHz (vs 1.6 GHz). : MediaTek MT7996 chipset supporting (tri-band Wi-Fi 7)

Safe range: <85°C is acceptable; >90°C may cause instability or reduced lifespan. If still too hot: Revert to stock firmware or install a passive heatsink mod.
