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.
Version 1:

Version 3:

Everything related to version 1
Specifications:
  • 300MHz processor

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!

In the archive file for the firmware and kernel modules / packages just in case.

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).

Please do not throw stones at me right away) The router v1, the firmware was a drain, using the usb cord as power and the patch cord connected it to the PC, went to the router at 192.168.0.254, chose the firmware update, indicated the path to the bin file (firmware ROOter mr3020-v1-GO2019-03-1) was installed, the router rebooted and that's all, after which I could not go to the router at the same address: sorry:

Thank you, everything worked.

Come on in 192.168.1.1
and the computer must get the address again from this network, just pull the cable back and forth

Try to switch the modem to only 3g mode, for example, and watch

In the "service type" list, select only UMTS instead of UMTS / GPRS?

* agent007-56,
3G mode does not translate the router and modem. From the router, this mode is not controlled (more precisely, you can do it, but it is more difficult)
the simplest thing is to connect to the computer and execute the commands via dc-unlocker (for each modem, its own)

Want to connect in bridge mode to expand the Wi-Fi zone?

No, I want to connect via openvpn to a server to get through. All operators are now giving NAT address addresses;

By the way, I wanted to set up the first bridge, but the Padawan firmware is very capricious about this (((

All good.
Can someone tell, already the whole brain broke.
There is E173
Serial No: XVA5TA1092910584
Firmware Version: 11.126.85.00.209
Compile Date / Time: Jun 21 2010 20:27:27
Hardware ver. : CD1E153M
Dashboard Version: UTPS11.300.05.15.143_MAC11.301.09.01.143
Chipset: Qualcomm MSM6290
Voice features: Enabled
SIM lock status: Unlocked
Attempts to enter the code: 2 (left unblocking attempts: 8).

I was sitting on the stock firmware (router) + Simka Tele2. And it seemed like everything was fine except for permanent communication breaks.

I decided to reflash.
At first I installed ROOter, but I couldn’t pick up and see the modem, but when I connected the E3276 converted to hilink everything is fine.

Now set the last cheerful snowdrop.
And, damn it, I don’t understand what needs to be done so that the modem rises and sees.

Also, soryan, did not understand how to install packages. Well, I downloaded them, well, they lie on the computer on the hard. How to show them?

Thanks to all

It did not work either by QMI or by NCM.
It turned out to connect under the protocol UMTS / ZHPRS.
Basically wound up.

* VeterR63,
this thing is trained to take packages from the web server
Web server can be installed on your home PC
or else where webserver lift
just kind of on the snowdrop and his native server with packages running.

There is a Petra BB cellular antenna with a 4G modem installed and a TP-Link TL-MR3020 router connected by a twisted pair (PoE) with Time Capsule. The TP-Link TL-MR3020 router distributes addresses (DNCP) to home network devices, and the Time Capsule is enabled in bridge mode.
Tell me how to disable DNCP and DNS in the TP-Link TL-MR3020 router firmware “Vigorous snowdrop”, in order to assign the server function to Time Capsule.

* VeterR63,
I looked right now snowdrop on my router
in the config there is src / gz peppy_snowdrop_corehttp://pub-dn07.r7494.ru/bp2-4/mr3020v1
The list of packages is completely updated from this repository.
another thing is that there is no free memory in the router
packages for all modems are put
