Flash the Netgear WAX206 (AX3200)

The WAX206 is an inexpensive mainline-OpenWrt target on the same MediaTek MT7622 platform as the well-known Linksys E8450 / Belkin RT3200. This guide flashes it to vanilla OpenWrt, then hands off to the agent install.

Why flash? The WAX206 ships Netgear’s stock firmware, not OpenWrt. The wifihaven agent runs only on vanilla OpenWrt — Netgear stock is not a supported target. Flash OpenWrt first; don’t run the installer on Netgear stock.

1. Download the OpenWrt image

For the first flash off Netgear stock you need a factory image. Get it from the OpenWrt Firmware Selector (search “Netgear WAX206”): 

openwrt-<version>-mediatek-mt7622-netgear_wax206-squashfs-factory.img

The squashfs-sysupgrade.bin image is for later upgrades only; the initramfs-recovery.itb is only for the recovery path below.

Verify the checksum before you flash — a wrong image can brick the router. Check the SHA-256 of your download against the value the Firmware Selector shows (and the sha256sums file under downloads.openwrt.org/releases/<version>/targets/mediatek/mt7622/). The exact reference build we validate against, with its pinned checksum, is in the full WAX206 install doc.

2. Flash from Netgear stock firmware

  1. Power on with WAN unplugged; plug your laptop into a LAN port.
  2. Browse to http://192.168.1.1 (or routerlogin.net) and log in to the Netgear admin UI.
  3. Go to Advanced → Administration → Firmware Update and select the …-squashfs-factory.img image.
  4. Netgear warns the firmware is older / not a Netgear image — that’s expected; confirm past it. The device reboots into OpenWrt.

If the OEM UI refuses the image, use the nmrpflash path below to push the same factory image.

3. First boot on OpenWrt

After the reboot the router is at 192.168.1.1 on clean OpenWrt defaults.

  1. Keep your laptop in a LAN port on DHCP and renew the lease.
  2. Browse to http://192.168.1.1 (LuCI) and set a root password.
  3. SSH in (ssh root@192.168.1.1) and confirm the firmware: 
    cat /etc/openwrt_release
# Expect DISTRIB_TARGET='mediatek/mt7622'

4. Turn on Wi-Fi (it’s off by default)

Vanilla OpenWrt ships with both radios disabled and no wireless network, so right after flashing you’ll only have wired connectivity — that’s expected. Turning it on is the same on every OpenWrt router, so we keep it on one page: Turn on Wi-Fi → (LuCI or SSH). Do it before you unplug the laptop.

5. Install the wifihaven agent

The box is now on vanilla OpenWrt. Follow step 2 of the setup page to run the one-line installer, or the full OpenWrt install doc. Baseline config and apk-release quirks are covered in the WAX206 install doc.

Recovery if a flash goes wrong

Netgear routers recover over the NMRP protocol, which nmrpflash speaks — no case-opening required.

  1. Install nmrpflash on your laptop and connect it to a LAN port of the (off) router.
  2. Give the laptop’s wired interface a static address on 192.168.1.0/24.
  3. Run nmrpflash pointed at your interface and the factory image, then power the router on so it catches the NMRP advertisement during boot: 
    nmrpflash -i <your-wired-interface> \
  -f openwrt-<version>-mediatek-mt7622-netgear_wax206-squashfs-factory.img

Use the OpenWrt …-factory.img to reinstall OpenWrt, or a Netgear stock .img to return to vendor firmware. The serial/TFTP U-Boot fallback is documented on the OpenWrt WAX206 device page.
