TP-Link TL-WR703N

TL-WR703N позиционируется как "3G travel router". В нем нет встроенного 3G модема - просто OEM firmware поддерживает USB 3G модемы, и oem firmware содержит драйвера USB модемов! Забавно, ведь с OpenWrt ЛЮБОЙ роутер с поддержкой USB поддерживает 3G устройства… ;-)

Выпускается с августа 2011 в Китае.

Устройство во многом сходно с TL-MR3020.

Unlike many newer TP-Link devices, there appears to be no hardware differences between the version for the Chinese market and the version for the international market.

It was the first device that utilised the AR9331 chipset to be ported to OpenWrt. Newer TP-Link devices (such as the TL-WR741ND v4.x also use AR9331).

Возможности

  • Atheros AR7240 CPU (400Mhz)
  • Atheros AR9331 Chipset (integrated wireless)
  • 802.11 b/g/n 150Mbps (130Mbps real)
  • wireless power output 20dBm - 100mW
  • 4 MB flash memory
  • 32 MB RAM
  • USB 2.0 port
  • Powered via micro-USB socket
  • Tiny form factor: 5.7cm x 5.7cm

Установка

  1. Please see generic.flashing for a generic description of the OpenWrt installation process.

Power consumption

This router is standardly powered via USB at 5V. The voltage regulator inside is unknown, but its input voltage should be at least between 3.7V - 5.5V, but not over 5.5V. The device will get damaged at too high voltages. Maximum current draw at 5V is 185mA (OpenWrt boot), average current draw with WiFi at 18dBm is 100mA, without WiFi 80mA. Hence the average router power consumption is 0.5W, which is incredibly low.

Power consumption will be higher if a USB device is attached to its USB port!

Serial console

The serial console connector does not utilise the regular TP-Link pinouts. Two pads labelled TP_OUT and TP_IN are the TX and RX signals.

Note that the pads can very easily be lifted. There is slightly more mechanical strength if you can solder to the surface-mount components to which the pads are connected–but this also takes care–your device could easily be destroyed. Make sure that your connection is secured so that tension cannot be applied to the solder points when you connect to an external device.

Прошивка

Snapshot image was broken around 18/11/2011, but from 26/11/2011 that was fixed.

Snapshot image was broken around 29/05/2012, but from 01/06/2012 that was fixed.

Snapshot images are always risky. Check the forum discussion for latest opinions on available images.

Upload the latest snapshot via the web interface (default: 192.168.1.1 / admin / admin).

Download latest squashfs-factory.bin or squashfs-sysupgrade.bin firmware for WR703N.

For systems without a web interface, you can flash a sysupgrade file with mtd:

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin
mtd write openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin firmware
reboot

Note that this will not destroy the contents of the file system, so any old modules under /lib/modules/x.y.z will still get loaded. If you don´t get a telnet login after reboot, try rebooting again.

To flash from the Chinese web interface, at the present time you would select the last menu item on the left, and then the third submenu item. This initiates a popup with two buttons–the upper right one allows you to browse to find the file you want to flash on your PC, the lower left one initiates the flash.

When you roll over an item on the Chinese web interface, the rollover text will indicate which item you are selecting.

Failsafe mode

When the configuration no longer allows you to log in via any network connection (e.g. lost password), the OpenWrt failsafe mode can be entered via the single "Reset" button on the device. However, in contrast to the generic failsafe instructions, for the TL-WR703N you have to wait for ca. 12 seconds before pushing the "Reset" button after powering on the device. If the button is pushed immediately after powering on, the single blue LED will start blinking, supposedly indicating some failsafe firmware recovery mody of the embedded bootloader (not yet discovered how to use it). In this mode, the OpenWrt failsafe is not being started. Instead, wait for slightly longer than 10 seconds and - as soon as the LED starts blinking for the first time after powering on the device, push the "Reset" button for ca. 1-2 seconds. Immediately afterwards, the LED will blink rapidly (multiple Hz) and OpenWrt will be in failsafe mode.

Back to original image

  • Setup serial console 115200 8n1
  • Enter "tpl" as soon as U-Boot announces "Autobooting in 1 seconds"
  • Download the original image: http://www.tp-link.com.cn/download/2011930104462.rar extact to tftp folder
  • Setup your eth0 to 192.168.1.100, you can check detail by 'printenv'
  • Run blow command under U-Boot:
tftpboot 0x81000000 wr703nv1_cn_3_12_11_up(110926).bin
erase 0x9f020000 +0x3c0000

bootm 9f020000

Internal images

You can see the serial connector labeled TP_IN and TP_OUT on the bottom right. GND is right next to it on the right pin of C55.

AN1 on the bottom right is the strip antenna for wifi.

GPIOs

The AR933x platform provides 30 GPIOs. Some of them are used by the router for status LEDs, buttons and other stuff. The table below shows the results of investigations:

Wi-Fi Client Bridging

To set your WR703n into Wi-Fi Client Bridge Mode, please read the following Links.
http://trac.gateworks.com/wiki/relayd
http://wiki.openwrt.org/doc/recipes/relayclient

This should be a recipe to set the WR703n into static Client Bridging Mode over Wi-Fi.

Аппаратные моды

  1. as a beginner, you really should inform yourself about soldering in general and then even obtain some experience!

Here are some interesting hardware hacks for the TL-WR703N, from the OpenWRT forum:

Мод 64MB памяти

The Device uses a DDR1 16Mbit x 16bit (16Mibit*16=256 mebibit. 256 mebibit/8=32MiByte) 400MHz chip Zentel A3S56D40FTP. Replace it with any 32Mbit x 16bit chip. 333MHz instead of 400MHz also works fine. It's quite hard to find these chips. The best chance is to have a look at DDR-SODIMM. Since there are no 64Mbit x 16Bit DDR1 Chips available → no 128 MB mod!

Working chips:

  • Hynix HY5DU121622DTP-D43 (From Mustang DDR-SODIMM 512 MB)
  • Hynix HY5DU121622CTP-D43 (From Hynix DDR-SODIMM PC2700S-25330 512MB DDR 333MHz CL 2.5, chips are 400Mhz compatible due "D43" marking.)
  • Infineon HYB25D512160BE (From Infineon DDR-SODIMM 512 MB)
  • Elpida EDD5116ADTA-6B-E (From Elpida DDR-SODIMM 512 MB)

Additional list that may work:

By default router able to see all 64MB.

WR703N Expander board and case

Kean Electronics in conjunction with the Sydney Hackerspace has developed WR703N Expander board as Open Hardware, all schematics are available online on their website - http://www.kean.com.au/oshw/WR703N/

Connector Info

  • The upstream USB connection is intended to come via a 4 pin header plugged into the WR703N PCB below (existing USB connector removed).
  • You can also populate a mini-B connector for connection to any upstream USB host via a
  • You can populate up to 3 USB A female connectors, or use 0.1" headers/connectors to mount USB connectors
  • USB1 and USB2 are intended to be standard right angle connectors, but will also take vertical style.
  • USB2 is recessed - partly to make the PCB able to be mounted very low on top of the WR703N PCB, but it also makes it suitable for very small USB drives (Sandisk Cruzer Fit).
  • USB3 can be a right angle or more usually a vertical connector. Or left off completely.
  • If a right angle connector is used for USB3, you can't easily use PORTB (and you should probably put some insulating tape over the PORTB pads).
  • The PORTA and PORTB headers are similar to the common SparkFun FTDI connector, although they include RTS instead of DTR.
  • The GPIO connector is intended to be a standard 2x5 box header.
  • See the schematic for pin outs of the GPIO and serial ports. Due to space restrictions, the extra 8 GPIO's from PORTB are not routed out.

Custom IPv6 image for wr703n

a custom image with ipv6 support: radvd, wide-dhcpv6, 3g stick support, made for RCS-RDS Fiberlink dual stack PPPoE service, but should be okay for static wan settings on other ISPs: http://www.ip6.ro/firmware/wr703n/
