 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).

 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.

  ==== 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 [[http://wiki.openwrt.org/doc/howto/generic.failsafe|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 [[http://wiki.openwrt.org/doc/howto/generic.failsafe|failsafe mode]].

+===== USB port and monitoring Serial Console via USB-Serial =====
+The USB port on the WR703n is not compatible with USB1 devices (aka full speed) and only works properly with USB2 (aka high speed) devices. You can however plug a USB-Serial adapter as long as you plug that through a <$10 USB2. While you're at it, use another USB port to plug in a USB key and write data there (like serial console logs) so as not to wear out the built in flash.

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!

Replace it with any 32Mbit x 16bit chip. 333MHz instead of 400MHz also works fine. It's quite hard to find these chips. One of the ways to get them is to have a look at DDR SO-DIMM (because SO-DIMM modules are shipped with x16 chips). Since there are no 64Mbit x 16bit DDR1 Chips available -> no 128 MB mod!
+The most easy approach is to seek for a 4-chip DDR 256 MB module. These all have x16 chips too. Chips only on one side (not to be confused with double-sided 256 MB modules with 4 chips on each side) and only 4 of them - that's the best chance to get some. They represent a small percent among usual 8-chip modules but this is equalized with the amount and "cheap as dirt" price of such DDR 256 MB modules.
