TP-Link TL-MR3020

See also TL-MR3040 and TL-WR703N or TP-Link TL-MR10U, TP-Link TL-MR11U, TP-Link TL-MR12U and TP-Link TL-MR13U
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 a certain range of 3G/4G modems to be externally connected to USB because it contains drivers for those USB modems! Ignore that, because with OpenWrt ANY router with USB supports 3G/4G hardware … ;-)

TP-Link TL-MR3020

The router is powered through a mini-USB socket stub (5V) and comes with a USB power adapter.

Power consumption

Input voltage: The router will function correctly when powered with voltages as low as 3.3 Volts (determined experimentally) instead of 5V USB-Power. Thus, it can be powered directly from one single Li-Ion battery (which usually starts fully charged at 4.2V and has a nominal voltage of 3.7) without the need for an external 5V adapter.

This router is standardly powered via USB at 5V. The voltage regulators' 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 255mA (Active Download + LAN + WLAN + USBboot), average current draw with WiFi is 125mA, idle is 68mA. Hence the average router power consumption is 0.6W, which is incredibly low.

Power consumption will be higher if a USB device is attached to its USB port! More information and a rough diagram here Interesting webpage with more data about power consumption and so on

Installation

Currently the TL-MR3020 is supported in the stable OpenWrt version Attitude Adjustement.

So you can either download a daily-built snapshot or build your own from sources.

  • Download the latest Attitude Adjustment from here (recommended)
  • Download the lastest trunk snapshot here (risky)

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

Method Using Web GUI (Recommended)

Connect to the TL-MR3020 router via Ethernet cable at IP address 192.168.0.254, log in to the router's web GUI (default login/password: admin / admin) and overwrite the factory firmware by installing the openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin firmware image like a regular firmware update.

Wait for the progress bar to finish twice (the device will reset itself in the process), and proceed with basic configuration as with any fresh OpenWRT install.

Web GUI upload has been confirmed to work with v1.0, v1.4, v1.6, v1.7, v1.8 and 1.9 hardware revisions and requires no serial access unless something goes wrong.

See forum if you encounter problems.

Manual Method Using Serial Console and TFTP (Experts)

To install OpenWrt from the U-Boot console, you need to install a TFTP server on your computer (tftp-hpa is recommended).

Then download OpenWrt factory image to /srv/tftp (for example), and execute the TFTP server by typing tftpd -l -s /srv/tftp.

Connect the TL-MR3020 using a serial console and power up the TL-MR3020.

After a 1-2 seconds it shows Autobooting in 1 seconds, when displaying this enter tpl immediately.

OEM Mass Flashing

Flashing hundreds of devices using the web interface can be a real pain. You can use this shell script to automate it:

#!/bin/bash

# Pass the firmware file to be flashed as the first parameter.
#
# The second curl call will time out, but it's expected. Once the
# script exits you can unplug the ethernet cable and proceed to the
# next router, but KEEP each router ON POWER until the new image is
# fully written! When flashing is done the router automatically
# reboots (as shown by all the leds flashing once).

Install Snapshot Image

If you install openwrt from trunk, the firmware image doesn't include LuCi. You need configure wireless network from telnet to install Luci. You will need already working internet access.

For this example:

Main router:

Ip:         '192.168.2.1'
Ssid:       'Example-network'
Bssid:      '11:11:11:11:11:11'
Encryption: 'WPA2 - PSK'
Key:        'PaSSworD'
Channel:    '9'

( You need fill these by your network properities )

Terminal program:

Putty

After install trunk image wait few minutes then recycle power router and set your computer ip address to:

ip:      192.168.1.2
subnet:  255.255.255.0
gateway: 192.168.1.1

Start your terminal and connect 192.168.1.1 via telnet ( port 23 ). Right now LAN INTERFACE include wireless too. We need to set wireless to WAN interface. Change wireless configuration below example.

vi /etc/config/wireless

config wifi-device  radio0
        option type     mac80211
        option channel  9
        option hwmode   11ng
        option path     'platform/ar933x_wmac'
        option htmode   HT20
        list ht_capab   SHORT-GI-20
        list ht_capab   SHORT-GI-40
        list ht_capab   RX-STBC1
        list ht_capab   DSSS_CCK-40
        option disabled 0
        option txpower 27

config wifi-iface
        option device      radio0
        option network     wan
        option mode        sta
        option ssid        Example-network
        option encryption  psk2
        option bssid       11:11:11:11:11:11
        option key         PaSSworD

Wireless setup completed now we need to get ip WAN interface via main router dhcp server. Set your network config like below example.

vi /etc/config/network

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd48:931d:0f42::/48'

config interface 'lan'
        option ifname 'eth0'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option proto    'dhcp'
        option _orig_ifname radio0
        option _orig_bridge false

Reboot your router

reboot

Your terminal session will be closed. You need reconnect to router.

Test your router: If your router is properly connected to the internet you should get something like the below lines:

ping -c3 www.google.com
PING www.google.com (xxx.xxx.xxx.xxx): 56 data bytes
64 bytes from xxx.xxx.xxx.xxx: seq=0 ttl=52 time=88.295 ms
64 bytes from xxx.xxx.xxx.xxx: seq=1 ttl=52 time=87.783 ms
64 bytes from xxx.xxx.xxx.xxx: seq=2 ttl=52 time=87.503 ms

--- www.google.com ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 87.503/87.860/88.295 ms

Now you can install Luci and enable it by below commands:

opkg update
opkg install luci
/etc/init.d/uhttpd enable
/etc/init.d/uhttpd start

Now you can access LuCi interface by 192.168.1.1 with your browser.

Failsafe Mode

  • Set your computer's IP to 192.168.1.2, subnet 255.255.255.0
  • Connect the TL-MR3020 to your computer via ethernet
  • Power on the TL-MR3020
  • When the WPS button starts to blink:
    • on AA (Attitude Adjustment / 12.09) push the WPS button;
    • on BB (Breaking Barrier / trunk) move the sliding switch quickly from one side to the other.
  • Do this until the WPS button starts blinking faster.
  • The device is now in Failsafe-Mode
  • You may access it by using telnet 192.168.1.1

Info on resetting to OpenWrt defaults can be found at: generic.failsafe

Downgrade Attitute Adjustment from Trunk

Downgraded wrong image ( jff2 instead of squashfs ) cause cant get ip or connect to luci. Failsafe mode still working but firstboot command wont work because it is already on working. You can upload correct firmware and write it with mtd command but failsafe mode can't connect internet. You need to local tftp server to get firmware.

Set your pc ip 192.168.1.10/24 and gateway 192.168.1.1. Download mongoose http server and correct firmware same folder and start mongoose. It will host all files in his path ( if you start it from downloads folder it will host all files in downloads folder )

now we can get firmware via failsafe telnet:

wget http://192.168.1.10:8080/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
mtd -r write /tmp/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin firmware
Writing from /tmp/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin to firmware ...
Rebooting ...
/bin/sh: /sbin/reboot: Input/output error

DONT DO ANYTHING. Just wait and router reboot itself. wait few minutes and you will able to reach Luci via 192.168.1.1.

Restoring Original Firmware

generic.uninstall

Warning!
This section describes actions that might damage your device or firmware. Proceed with care!

With the TL-WR842ND router, there is a catch: the stock firmware is obtained from the OEM: http://www.tplink.com/en/support/download/?model=TL-MR3020

  • in case the file name of this firmware file does not contain the word "boot" in it, you can simply revert back to original firmware
  • in case the file name of this firmware file does contain the word "boot" in it, you need to cut off parts of the image file before flashing it:

An example of an image file with the word "boot" in it is mr3020nv1_en_3_17_2_up_boot(140408).bin.

Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware:

dd if=orig.bin of=tplink.bin skip=257 bs=512

You should transfer the firmeware image to the /tmp folder and revert back to original firmware (if availlable you can flash the firmware via the webinterface as well):

Via the safer method using sysupgrade:

sysupgrade /tmp/tplink.bin

Or you use the mtd method:

mtd -r write /tmp/tplink.bin firmware

It is also possible to revert to the stock firmware using the method with tftp described in "Manual Method Using Serial Console and TFTP (Experts)". (you still need the firmware images without the boot part).

OEM TP-Link firmware for the TL-MR3020 with the boot part removed to revert to the original OEM firmware:

Basic Configuration

Since this part is identical to the one recommended for generic devices, see Basic configuration.

Original Flash Layout

Please read the article Flash Layout for a better understanding. It contains a couple of explanations. Then let's have a quick view at flash layout of this particular device:

TP-Link MR3020 Flash Layout stock firmware
Layer0 spi0.0: 4096KiB
Layer1 mtd0 mtd1 mtd2 mtd3 mtd4
Size in KiB 128KiB 1024KiB 2816 KiB 64KiB 64KiB
Name u-boot kernel rootfs config art
mountpoint none none / none none
filesystem none none SquashFS none none

ART = Atheros Radio Test - it contains RF calibration data for the wifi. If it is missing or corrupt, wireless won't come up anymore.

Hardware

Opening the Case

The case consists of two parts: a white base and a gray lid. The lid has two snap hinges, one right above the mini USB connector and one on the opposite side about 10 mm left of the "TP-LINK" logo. The lid is additionally glued in place on the underside on all four sides. You can try to pry it open with a thin but very stable blade tool. Start above the ethernet port where the case is not glued, and work your way around the glued corner towards the "3G USB" port (no glue there) until you reach the logo side. You should now be able to peek inside the case on the lose corner.

Next proceed along to the LED side, but beware of the fragile light conductors running straight down beneath the clear plastic. They easily bend or break when you push-in your tool too far. Once three sides are open, you can steadily lift the lid until the remaining side breaks lose and neatly frees the second hinge in the process. If you work carefully and manage not to break either one of the two hinges, the gray lid should snap neatly back into place after some manual cleaning with a cutter knife.

Serial Console

Pinout
1 2 3 4
TX RX GND VCC SJ1

Pin 1 is clearly marked on the board.

To get a reliable serial connection, you might have to connect a 10k pullup resistor between TX and VCC. This is because the TX pin is connected to a voltage divider (2x5.6k) and a capacitor is put between the real pin and the TX connector. Some serial adaptors might work without the pullup resistor (confirmed for one ST3232-based adaptor), but others definitely require it (confirmed for a FTDI FT232RL-based model).

If you need a serial adaptor, you can build a serial hack adapter (DKU-5, CA-42). Relatively cheap, off-the-shelf and known-to-work alternatives would be SparkFun's FTDI Basic Breakout 3.3V and FTDI Serial Cable 3.3V (the resistor is not needed with this specific cable).

The right settings for accessing the serial console are as follows:

Bits per second: 115200
Data bits: 8
Stop bits: 1
Parity: None
Flow control: None

If you are using a Linux or Mac system, the easiest way to connect to the serial console would be the screen command. It comes pre-installed on OS X, but must usually be installed on Linux systems. When installed, just type in a terminal:

screen /dev/[device name] 115200

where [device name] is the name of your serial adaptor, usually tty.usbserial* on Mac and ttyUSB* on Linux. To quit screen, press CTRL-a, followed by CTRL-k, followed by y.

GPIOs

port.GPIO 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 some investigation:

Voltage level at GPIO in output-mode gpioX/value in input-mode when GPIO is:
GPIO Common Name PCB Name gpioX/value=1 gpioX/value=0 Floating Pulled to GND Pulled to Vcc

To make the GPIOs available via sysfs, the required ones have to be exported to userspace, as it is explained on a page of the Squidge-Project. Kernel modules occupying that resource need to be removed before (e.g. "leds-gpio" and "gpio-buttons"). In output-mode, voltage levels of the GPIOs were measured against GND, after the value 1 or 0 had been written to /sys/class/gpio/gpioX/value. In input-mode, the value of the file /sys/class/gpio/gpioX/value was read when the GPIO was floating (initial state), pulled to GND or pulled to Vcc.

The sliding switch has the following truth table:

Mode Switch GPIO18 GPIO20
3G 1 0
WISP 0 1
AP 1 1

LEDs

How to configure LEDs in general, see the LED section in the system.

The TL-MR3020 has 5 LEDs:

LED name LED print Internal name Trigger
Power Power symbol N/A (fixed supply) N/A
3G Internet symbol tl-mr3020:green:3g USB:1-1
Wireless LAN WLAN symbol tl-mr3020:green:wlan phy0tpt
LAN LAN symbol tl-mr3020:green:lan netdev:eth0
WPS WPS tl-mr3020:green:wps User preference

Buttons

hardware.buttons The TP-Link TL-MR3020 has one button and one sliding switch with three positions:

BUTTON Event
Sliding Switch BTN_0 and BTN_1
WPS Button WPS

The WPS button is located at the top (illuminated by the WPS LED) and can be easily pressed with a finger. The sliding switch is located at the side and has three positions: 3G, WISP, AP.

Sample scripts to read the sliding switch: on boot, on switch change, to change network configurations

U-Boot 1.1.4 modification for routers

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).

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.).

USB port and monitoring Serial Console via USB-Serial

The USB port on the TL-MR3020 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 USB 2.0 hub. While you're at it, use another port of the USB hub to plug in a USB thumb drive and write data there (like serial console logs) so as not to wear out the built-in flash.

See this page for more tips and how to create a serial console server out of your TL-MR3020: http://marc.merlins.org/perso/linux/post_2012-12-05_Serial-Console-With-WR703N.html
