A portable_router with an onboard 10400mAh rechargeable_battery. See also TP-Link TL-MR10U, TP-Link TL-MR11U and TP-Link TL-MR12U or TL-MR3020, TL-MR3040 and TL-WR703N.
Note: Many of these routers are marketed as a "3G travel router" but none actually include a 3G modem - the marketing term rather means that the OEM firmware supports USB 3G modems because it contains drivers for USB modems! Ignore that, because with OpenWrt ANY router with USB supports 3G hardware…

MR-13U has a rather big battery therefore it takes a long time to charge it. It might seem for the first time that nothing happens after connecting a charger. The router has 5 leds (4 blue and 1 red) to indicate the battery status. When you press the battery button status LEDs light up. When the battery charging is in progress LEDs stay on and after it's finished they go off. While charging the router consumes about 7W (measured with watt meter in power outlet) If the battery level is low one red LED light up and stays this way even if the battery check button is released.

This section deals with how you install OpenWrt from a device freshly opened. Plus the steps required such as reset to factory defaults if the device has already been configured
Note: Reset router to factory defaults if it has been previously configured.

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload image file for sysupgrade to LuCI
- Wait for reboot
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
- Download the latest firmware http://service.tp-link.com.cn/detail_download_1226.html unpack the archive. You should have mr13uv1.bin inside it. This file has little over 4MB so it contains a bootloader. You can't flash it directly from OpenWrt web interface or through ssh and mtd command. First you have to strip the .bin file of the bootloader. For this you use a tool called dd.
- Cut first 0x20200 bytes from original firmware
dd if=mr13uv1.bin of=mr13uv1_noboot.bin skip=257 bs=512
Then upload it to the router
scp mr13uv1_noboot.bin email@example.com:/tmp
- Type your root password when prompted and a slow upload will start.
- SSH to your router and perform the following commands:
- Flash via mtd
mtd -r write /tmp/mr13uv1_noboot.bin firmware
This should reboot the router after writing is finished. If it reports an error DO NOT restart the router because you will brick it. Instead check again if you used the right firmware which should have 3932160 bytes.
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
The default network configuration is:
|Interface Name||Description||Default configuration|
|br-lan||LAN & WiFi||192.168.1.1/24|
|vlan0 (eth0.0)||LAN ports (1 to 4)||None|
|vlan1 (eth0.1)||WAN port||DHCP|
Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
→ hardware.button on howto use and configure the hardware button(s).

Forum member 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 GitHub repository.
This modification started from 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.).
- as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!
