If you own a W1700K router and have recently flashed OpenWrt onto it, you might have noticed something alarming: the device runs hot. Very hot. Searching for "w1700k openwrt hot" brings up dozens of forum threads filled with users concerned about thermal throttling, system instability, and even long-term hardware damage.
But is this heat normal? Is it a design flaw, or is OpenWrt simply unlocking power that the stock firmware kept hidden?
In this deep dive, we will explore exactly why the W1700K runs hot under OpenWrt, what temperatures are considered "safe," and the definitive steps to cool it down without sacrificing performance.
# Common paths
cat /sys/class/thermal/thermal_zone0/temp
cat /sys/class/hwmon/hwmon0/temp1_input
Divide by 1000 for Celsius.
Install lm-sensors:
opkg install lm-sensors
sensors
Issue: Users report the W1700K running abnormally hot (surface temps >65–70°C) after flashing OpenWrt, especially under load (WiFi + NAT + SQM).
Root Causes:
mt76 driver (MediaTek) on Filogic 820 may keep radios at higher tx power than stock.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
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).
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.

uptime
logread | tail -n 100
dmesg | tail -n 100

netstat -tunp | sort and conntrack -L | wc -l. Limit services exposed to WAN; enable firewall rules or fail2ban-like protections.Quick checklist (do these in order): power-cycle → check logs/uptime → monitor temp & top → stop heavy processes → update/reflash OpenWrt → clean/ improve cooling → consider hardware replacement.
If you want, tell me the exact device model, current OpenWrt version, outputs of cat /proc/cpuinfo, cat /sys/class/thermal/thermal_zone0/temp, and top -b -n1 | head -n 20 and I’ll give tailored next steps. w1700k openwrt hot
That’s a compact but intriguing review snippet: "w1700k openwrt hot".
Here’s a quick breakdown of what the user likely means:
Given it’s an “interesting review,” likely it’s about thermal issues: The device runs unexpectedly hot under OpenWrt, possibly due to missing CPU frequency scaling, inefficient drivers, or heavy software (e.g., SQM, VPN, or DPI). Or the reviewer finds the combination surprisingly capable (“hot” as in good performance).
If you want, I can:
Which direction would you like to go?
While the stock firmware is OpenWrt-based, it is virtually unmanageable without the ISP's app.
Support: It is not yet in the stable main branch of OpenWrt.
Custom Firmware: Developers have successfully flashed vanilla OpenWrt via the serial port (UART).
Performance: Users who have flashed it report reaching near-gigabit speeds over Wi-Fi with latencies around 6–7 ms.
Working Features: 6GHz Wi-Fi is functional in recent builds, but 10G Ethernet ports are still being stabilized. 🔥 Heat and Hardware Issues
The "hot" nature of this device is a common discussion point in user reviews. Quantum Fiber W1700k support - Page 20 - For Developers
The Gemtek MXF-W1700K (distributed by Quantum Fiber as the W1700K) has rapidly become a "hot" topic in the networking community due to its top-tier Wi-Fi 7 hardware and the emergence of enthusiast-driven OpenWrt support. Why the W1700K is "Hot" Hardware
The W1700K is considered a powerhouse because it packs high-end specifications rarely found in ISP-provided equipment:
Processor: Quad-core 1.3 GHz ARM Cortex-A53 (Airoha AN7581 series). Memory: Massive 2GB DDR4 RAM and 512MB Flash storage. Connectivity: 2x 10GbE ports and 2x 1Gbe ports.
Wireless: Wi-Fi 7 (802.11be) with 4x4 MU-MIMO across 2.4GHz, 5GHz, and 6GHz bands.
While the stock firmware is often locked down or requires an app for configuration, flashing OpenWrt unlocks the device's full potential, including features like 6GHz support (which may require minor patches) and advanced network management. Installing OpenWrt on the W1700K
Flashing this device is an advanced procedure that typically requires a serial connection. You can find detailed technical discussion and community builds on the OpenWrt Forum. W1700K OpenWrt Hot: Taming the Heat for Maximum
Access UART Pins: You must open the case to access the TTL serial console pins located at the bottom left of the board.
Chainloader U-Boot: Because the stock bootloader is restricted, users often install a "chainloader" version of U-Boot to boot OpenWrt images.
TFTP Transfer: Firmware files (like the ubi-initramfs-installer.itb) are typically transferred over the network via a TFTP server while connected to the router's serial console.
Official Images: While support is maturing, official snapshot builds can be found on the OpenWrt Firmware Selector. Managing Heat and Overheating
With a 1.3 GHz quad-core CPU and high-power Wi-Fi 7 FEMs, the W1700K can generate significant heat during heavy operation. To keep it running smoothly:
Ventilation: Ensure the router is in an open area. Avoid enclosed cabinets or placing items on top of its vents.
Active Cooling: Some enthusiasts add small 120mm USB fans or cooling pads to the exterior to maintain lower temperatures during high-speed 10GbE or 6GHz transfers.
Software Optimization: Keeping firmware updated ensures you have the latest performance patches, which can sometimes optimize CPU usage and reduce heat. Quantum Fiber W1700k support - Page 20 - For Developers
