NETGEAR WNR1000 v2

Note: Official images are too large as of 17.XX. Use the Community Builds in the forum topic URL below for the latest 17.XX, 18.XX, and 19.XX images. https://forum.openwrt.org/t/builds-for-netgear-wnr1000v2-wnr1000v2-vc-wnr612v2-wpn824n-wnr2000v3/39360

WNR1000-100PES - very similar to WNR2000v3 / WNR612v2

WNR1000v2 also exists as WNR1000v2h2 - instructions for WNR1000v2 also work for WNR1000v2h2 without modification.

→ Install OpenWrt (generic explanation)

Note: Ready-to-install firmware images for OpenWrt 17.01.7 and 18.06.8 and 19.07.3 are available as of June 2020 via OpenWrt Community Builds. These are customized builds that do include opkg due to inadequate flash size that cause stock, official OpenWrt builds to bootloop or not retain settings upon reboot.

Updated Installation Instructions

I tried web-interface upload of v2.img linked above, router complained 2x about image, using ambiguous language about cause of failure; filename pattern violation, or image content, or checksum..

1. alert/modal/popup “Firmware upload failed, please check your file” I dismiss that, and click ok/yes 2. another error, now inserted into web-page <div>, text refreshes away before I can copy-paste it

Upgrade WNR1000v2 to the latest factory firmware: 1.1.2.60. Otherwise, the power LED may not behave properly.

You need to place the device into failsafe mode. For booting into failsafe mode, you need to power up the device while holding the reset button with a pin. The power LED should have an amber colour. Hold the button until it is starting to flash green. It starts to flash green after it flashes the amber LED for six times. After that, the device is in failsafe mode, accepting a firmware via its TFTP server. The device should respond to pings at 192.168.1.1, although the responses may be malformed.

Configure your ethernet interface with a 192.168.1.0/24 IP address. I use 192.168.1.2 with netmask 255.255.255.0 but it should work with any free address from that block.

You need a TFTP client for this purpose. You may check the OpenWrt wiki for more information if you aren't familiar with the procedure. You need openwrt-ar71xx-generic-wnr1000v2-squashfs-factory-barrier-breaker-r44095.img, download can be found at https://gist.github.com/SaltwaterC/ef49c8a4df81c8896153. It's only image what can be flashed sucseesfuly, later images stuck at bootloop.

tftp 192.168.1.1
binary

put openwrt-ar71xx-generic-wnr1000v2-squashfs-factory-barrier-breaker-r44095.img

After boot you can upgrade openwrt to a newer version with sysupgrade.

→ port.serial general information about the serial port, serial port cable, etc.

The serial port is found at JP2. Pin 1 is marked with dot.

GPIO LEDs and buttons on this device are connected to GPIO controllers on AR7240 SoC and AR9285 wireless chip.

Controlled by AR7240 SoC (18 GPIOs total, LAN LEDs shared with built-in Ethernet switch) :

Controlled by AR9285 wireless chip (12 GPIOs total) :

Notes:

• [0] - needs reprogramming of SoC to deallocate GPIO pins from JTAG
• [1] - needs reprogramming of SoC to deallocate GPIO pins from built-in Ethernet switch; required for different link speed colors
• [2] - 'phy0radio' trigger does not work, use default 'phy0tpt' or 'wlan0' netdevice instead
• [3] - this is amber light on power LED (labelled TEST in u-boot sources)

There is a project allowing to build custom u-boot image https://github.com/realmicu/uboot-wnrmod2k It could be used if flash memory chip was replaced or to obtain additional functionality.
