Netgear WNR1000 v2

Not recommended for future use with OpenWrt due to low flash/ram.
Limitations in extensibility and stability of operation are to be expected.
See 432_warning for details.

WNR1000-100PES - very similar to WNR2000v3 / WNR612v2

Installation

Install OpenWrt (generic explanation)

FIXME Please add the installation procedure here.

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.

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

GPIO

GPIO LEDs and buttons on this device are connected to either AR7240 SoC or AR9285 wireless chip, so not all of them are accessible to stock version of OpenWrt 15.05 (generic ath9k driver does not register AR9285 GPIOs in kernel). Please read more in Patches section below about current status of addressing these issues.

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

Type Function GPIO Polarity Notes
LED WAN AMBER 0 (0, 0) active low
LED TEST AMBER 1 (0, 1) active low aka POWER AMBER - see note [3]
LED LAN1 AMBER 6 (0, 6) active low shared with JTAG - see note [0]
LED LAN2 AMBER 7 (0, 7) active low shared with JTAG - see note [0]
LED LAN3 AMBER 8 (0, 8) active low shared with JTAG - see note [0]
LED POWER GREEN 11 (0, 11) active low
LED LAN4 AMBER 12 (0, 12) active low
LED LAN1 GREEN 13 (0, 13) active low link activity - see note [1]
LED LAN2 GREEN 14 (0, 14) active low link activity - see note [1]
LED LAN3 GREEN 15 (0, 15) active low link activity - see note [1]
LED LAN4 GREEN 16 (0, 16) active low link activity - see note [1]
LED WAN GREEN 17 (0, 17) active low link activity - see note [1]

Controlled by AR9285 wireless chip (12 GPIOs total, unaccessible with default ath9k driver, see Patches section below) :

Type Function GPIO Polarity Notes
LED WLAN BLUE 53 (1, 1) active low not all triggers work - see note [2]
LED WPS GREEN 57 (1, 5) active low
Button WPS 58 (1, 6) active low
Button RESET 59 (1, 7) active low
Button RFKILL 60 (1, 8) active low

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)

Patches

Patches providing full GPIO support on WNR2000v3 / WNR612v2 / WNR1000v2 have been submitted to trunk (https://patchwork.ozlabs.org/project/openwrt/list/?submitter=68145). They are included in OpenWrt starting from version r49077.
All above patches and their versions backported to Chaos Chalmer (15.05) are available at https://micu.webserwer.pl/pmwiki/pmwiki.php?n=OpenWRT.Patches.
