-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. The domestic Chinese/​Asian versions and those for the European and American markets differ significantly.

-==== 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.).
