TP-Link TL-MR3020 - Discussion

Attached Image


The MR-3020 is a small portable router powered by miniUSB 5V. In practice, 3.3V is enough for the operation of the built-in iron. Naturally, the USB port will also have a low voltage.
In fact, this is not a router. This is a cool ready-made hardware for developing application solutions.

Currently there are two modifications of version 1 (v1.x) and version 3 (v3.x)
If you ask a question about the firmware, specify the name of the firmware and the version number.
Almost all alternative firmware are based on OpenWRT, but there are also Padavan ported linaro firmware for TP-Link on MT7628 (v3) chips.

How to determine the version of the router
Need to look at the sticker on the bottom of the router.

Checked with modems:
E1550, E392
M100-3 aka ZTE MF823 - without information about the network and SMS, only the mode of connecting to the network.

My firmware "Do it yourself - a model for the assembly"
There is nothing in the firmware except luci (web interface)
Kernel 3.10.58
Build 43052 10.25.2014
Firewood is sewn into the core for usb drives and scripts for mounting disks / partitions are installed.
Support for FAT16 / 32 and EXT2 / 3/4 is sewn into the core.
For FAT, the default page is 866 (embedded into the kernel)
Also, the default is UTF-8 stitched.
Support only mr3020!
Installation only on mr3020!
Firewall is not. DHCP is.

My firmware "Home NAS server ver.1"
Luci web interface
Module to configure SAMBA
Supports SFTP protocol. (Encoding is not samba)
Kernel 3.10.58
Build 43052 10.25.2014
Firewood is sewn into the core for usb drives and scripts for mounting disks / partitions are installed.
Support for FAT16 / 32 and EXT2 / 3/4 trial support for NTFS with recording (not yet tried) is sewn into the kernel
For FAT, the default page is 866 (embedded into the kernel)
Also, the default is UTF-8 stitched.
Support only mr3020!
Installation only on mr3020!
Firewall is not. DHCP is.
Firmware for familiarization with Samba services. Tries to automatically mount everything connected to the usb port.
Attention! In the out of the box mode, disks with existing files are mounted in utf-8. Therefore, the file names with Cyrillic will be unreadable.
To fix this nuance you need to conjure with mount options.
If you connect a blank disk specifically for use as a NAS, then everything will be fine.
In the future, perhaps, I will make scripts that simplify the configuration and preparation of the disk for use as a NAS server.

My firmware for USB modems "Vigorous Snowdrop"
Attention! Router address after firmware 192.168.4.254
Assembly 03/01/2015
44570
Kernel 3.10.70

Features:
  • Compiled based on OpenWRT.
  • Firmware for MR3020 only
  • Support for different usb modems
  • (I checked the work on E392, E1550, E3272, E3372, MF823, Android, LAN2USB)
  • Support for Android and ios modem mode
  • Optimized luci code
  • Russian language web interface
  • Protocol support pptp, l2tp, pppoe, ppp
  • Support for relay protocol for bridges
  • QoS
  • DDns
  • Support ussd requests from the web interface
  • Receive / send SMS from the web interface (support for utf8 is only for reception)
  • Removing from the SIM card via the web interface
  • Shows the signal level and add. information in the web interface
  • Qmi support by means of uqmi (Settings in luci; on some modems, problems with disconnection; it does not break.)
  • The ability to make a bridge between the QMI-modem and another router, for example Mikrotik
  • NCM support (currently only in comgt, you can configure the connection with pens)
  • MBIM support (not verified, no modem supporting this protocol)
  • Support for disks with FS FAT16 / 32 and EXT3. The ability to transfer the root FS to external media (extroot)
  • Selection of frequencies for registration in the network. (Scheduled)
  • Separate page showing only the signal level
  • Wifi enabled by default

New concept of adding your own buns. Completely redesigned mechanism for working with SMS. Significantly reworked mechanism for receiving responses ussd. Works to send responses in ussd requests. Checked with biline. Long SMS is not able to send. Due to the fact that many will want to transfer the root file system to an external partition in order to install various additional packages, I compiled some so that the kernel version is the same (some kernel modules, samba, openvpn, transmission etc).

Pictureshereand version 2.1version 2.3.2 with a working OpenVPN client (polarssl) (Update version 2.3)
Changes:
The issue with authorization CHAP / MSCHAP is solved.
The problem with the button to delete SMS messages has been solved.
Added the button "Reload port" (de-energizes the usb port for a few seconds. It will work if the jumper is not soldered).
Added the correct use of metrics when connecting via NCM and QMI protocols. (Now it will be easier to raise the VPN connection of the modem connections).
Added repository with packages to the server. (To work correctly in the settings, disable the packages with modules by default and replace src / gz with src).

if you put on the processor router TP-Link TL-MR3020 radiator. What will change in your work?

Most likely - nothing changes: the volume of the housing 3020 is very small, the ventilation holes in him. Heat is released to go nowhere - that the radiator without.
However, the processor allocates small enough heat to overheat even in a "matchbox".
If we question cooling "edge worth" - try the failed top panel of the case, we come across such routers, to "pluck out" ...

Version 3, all the lights are blinking, it might be? Tried to flash with linux through tftp on openwrt, it did not happen. Then, when the diodes have blinked trying to flash with Windows via tftp, it did not happen. How to sew? The cap is no manual. Console connector on the router either, that is to say through the terminal does not connect?

To be honest - all this is seen and read. Just the top of this no, it is not convenient. Tried all described what you got rid of, not sewn, what is the reason I'll never know. If you hold the reset when on the device, the network on the wired interface appears, but no IP does not receive.

the wired network interface will appear, but no IP does not receive

you probably have not read, it is written everywhere - ask a static address to the computer 192.168.0.225
and that is all there is in a cap

All good, the next question is, do not know in this topic or via a modem, but oh well, adjusted if, in general, there is this device with iOS Bouncy snowdrop on 07.04.18 and modem E1750 Megaphone stitched. He worked with a megaphone normally, reception transmission were stable now preshol at Tele2, everything seems to be nothing stable download speed, but predachi chudit, send files, speed, flies up to about 12Mbps, seconds several predachi go, then stops through kakoeto time again same. that may be, the antenna I have an external, router or modem. may change that in the settings?

Rep: (1314)
Yesterday I bought a device for work tasks.
But immediately a problem emerged - if there is no Internet on the SIM card of the connected modem, the router, having understood this, starts to reconnect endlessly.
But this is not necessary for the work task, since the modem installed the SIM card (MTS) the modem goes to a closed corporate network with its APN, where there is no Internet in principle.
I understand that the router checks a certain address / addresses on the Internet for a connection, if there is none, it considers that there is no Internet and is trying to reconnect.
Question to the knowledgeable: how to disable this feature or change the address to check for tyrnet?
From technical support did not achieve anything.
...
I connect the same modem to a PC and establish a connection - there are no reconnections.
To check, I also put an ordinary SIM card with the Internet, everything is OK, the router holds.
