-Even though it is marketed as a //"3G travel router"//, the **TL-WR720N** does not include a 3G modem. It simply means that the OEM firmware and GUI support a certain range of USB 3G modems. OpenWRT supports USB 3G modems, too. The router is powered through either a AC source (100-240V, Chinese-style foldable plug, i.e. two prongs without hole), or a mini-USB socket stub (5V).+**__Note:__** TP-Link also markets a very [[http://www.tp-link.com/en/products/details/?model=TL-WR720N|different router under the same name]].

The domestic Chinese/Asian versions and those for the European and American markets differ significantly. Only the rectangular version available from China has been tested, so far.

-==== Internal Pictures ====+==== v4.0 notes ====
-{{:media:tl-wr720n001.jpg|}}+The hardware of v4.0 is almost the same as v3.0 so firmwares for v3.0 just work. The version number in images for v4.0 is 0x07200104 (0x07200103 for v3.0).
-{{:media:tl-wr720n002.jpg|}}+==== USB ports ====
-{{:media:tl-wr720n003.jpg|}}+It appears the hardware switch must be set to "3G" to make the USB port work. Otherwise the port has power output but devices connected can't be detected by OpenWrt.
-{{:media:tl-wr720n004.jpg|}}+==== Failsafe mode ==== 
 +-> [[doc:howto:generic.failsafe]]
-{{:media:tl-wr720n005.jpg|}} +Note that the **mount_root** command will not work. (You can use the [[doc:howto:generic.sysupgrade#netcat|netcat method]] to install a fresh copy of the system if necessary.)

 +==== U-Boot 1.1.4 modification for routers ====
 +Forum member [[https://forum.openwrt.org/profile.php?id=72549|pepe2k]] made a modification of **U-Boot 1.1.4** for **Qualcomm Atheros** SoCs based devices (the project is still being developed, so new devices and SoCs will be supported in the future). Up to date information, binary images and sources can be found on official [[https://github.com/pepe2k/u-boot_mod|GitHub repository]].
 +
 +This modification started from [[http://code.google.com/p/wr703n-uboot-with-web-failsafe/|wr703n-uboot-with-web-failsafe]] project, but supports more devices, all modern web browsers, has a lot of improvements and other modifications (like U-Boot NetConsole, custom commands, overclocking possibilities etc.).
