W1700k Openwrt

Yes – 100%. The W1700K running OpenWrt is one of the best value routers in 2025.

Who should do this:

Who should stick with stock:

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.

You have a router with only 1700 KB of available flash for firmware. A stock OpenWrt image is often 4–6 MB. To fit, you must build a custom, stripped-down image using the Image Builder, removing all non-essentials: no Luci (web UI), no IPv6, no firewall, no USB, no Wi-Fi encryption overhead. Just a lean, mean bridging/routing machine.

With OpenWrt installed, turn your W1700K into a network swiss-army knife.

Step 1: Set up OpenWrt Image Builder

# Download for your target (example: ar71xx, ramips, ath79)
wget https://downloads.openwrt.org/releases/23.05.3/targets/ramips/mt76x8/openwrt-imagebuilder-23.05.3-ramips-mt76x8.Linux-x86_64.tar.xz
tar -xf openwrt-imagebuilder-*.tar.xz
cd openwrt-imagebuilder-*

Step 2: Strip packages to the bone

make image PROFILE="yourprofile" \
  PACKAGES="busybox base-files libc uci opkg netifd" \
  DISABLED_SERVICES="dnsmasq dropbear odhcpd" \
  FILES="files/" \
  ROOTFS_PARTSIZE=1

Step 3: Manual squashfs tuning (if >1700KB)

Final size check:

ls -lh bin/targets/*/generic/openwrt-*-squashfs-sysupgrade.bin
# Must be <= 1740 KB (leaving 40KB for settings)

  • Problem: 2.5GbE WAN port only negotiates 1Gbps.

  • Problem: Bricked router (no LED, no ping).

    Quantum Fiber W1700k (specifically the Gemtek MX-W1700k ) has become a fascinating "holy grail" for the OpenWrt community. Once a locked-down ISP router provided by Quantum Fiber

    , it has been transformed by independent developers into a high-performance, open-source networking beast. The Hardware: A Hidden Powerhouse

    The excitement around the W1700k stems from its impressive internal specifications, which far exceed standard "free" ISP hardware. It features the Airoha EN7581 SoC , a modern Wi-Fi 7 chipset that offers: Tri-band Wi-Fi 7 (BE19000) capabilities. Dual 10Gbps Ethernet ports

    (one WAN, one LAN), making it a rare affordable entry point for 10-Gigabit home networking. Quad-core ARM Cortex-A53

    processor, providing plenty of headroom for heavy OpenWrt packages like SQM, VPNs (WireGuard), and ad-blocking (AdGuard Home). The "OpenWrt" Breakthrough

    For months, the W1700k was considered a "paperweight" for enthusiasts because of its secure boot and proprietary firmware. However, a dedicated community effort, chronicled extensively on the OpenWrt Forum , led to several major milestones: Bootloader Unlocking

    : Developers discovered methods to bypass the ISP's restrictions, allowing for custom partitions. The "Lorenzo" Builds : Frequent updates from developers like Lorenzo Bianconi

    have integrated support for the NPU (Network Processing Unit) and Wi-Fi 7 drivers. Community Support

    : Because the device is often sold cheaply on the second-hand market (eBay/Mercari) after customers switch ISPs, it has become one of the most cost-effective ways to run a Wi-Fi 7 OpenWrt setup. Why This Matters w1700k openwrt

    Installing OpenWrt on the W1700k isn't just about "hacking" a router; it's about reclaiming high-end hardware

    : It removes the ISP's ability to monitor traffic or push forced updates. Performance

    : Stock firmware often limits the 10Gbps ports or has poor bufferbloat management. OpenWrt unlocks full line-rate speeds. Sustainability

    : It prevents thousands of these high-spec units from becoming e-waste when customers cancel their subscriptions. Current State & Risks

    While support is maturing, it is still considered "experimental." New users often refer to the W1700k OpenWrt Flashing Wiki
