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.

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)

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).

It is the cry of the soul, or asking for help?
If the second, then
1. what kind of router firmware sewn - yellow, red, funnelweb?
2. The modem firmware (native, the parties usually, hilink)?
3. The operator and the type of existing 3G or LTE connectivity?


Who is such,http://prntscr.com/46298x, Standard.

Tried to put openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.7z and now with this link "Firmware ROOter (how many do not plug a modem, they themselves define and launch the connection)" both do not run the modem.

Good day,

I have a TL-MR3020 want to buy the MTS modem Huawei 824FT to work in 4G. Question: they compatible?



Rep: (88)
If we are talking about the E3272, which MTS 824 is compatible. Above people have written that the plant, even with the standard firmware. I tried a megaphone 100-4 (E3272) not worked in PPP mode and NDIS.

Please help: TL-MR3020, firmware out of the box - 8853A-MR3020V1, previously worked with a 3G-modem recently acquired a 4G-modem from Megafon Modem M100-4 (Huawei E3272), plugged in, it worked. Yesterday, accidentally pressed the WPS button, then there was a network with a different name TP-Link TL-MR3020 ... and stopped handing out online. Am on weekends in the country, the laptop is old, no wi-fi module, so the ability to diagnose your network, the connection check is performed via the tablet. Pressing the reset did not change anything. I decided to enter the web-based interface of the router, dig into the settings. So - does not go o.O. I enter in the address bar of any of the three browsers 192.168.0.254, and after a moment's attempts to connect issues webpage is not available. On the router are lit power and LAN. If anyone knows, tell me what it might be? Thanks in advance!

Rep: (88)
It is necessary to try to disable the modem to reset the router to factory settings and then have to go on 192.168.0.254. After that, connect the modem and configure as usual.



Rep: (4)
The modem is turned off course, it is plugged into a laptop, the reset did ... :-(



Rep: (88)
Then we have to watch what address is assigned to the laptop and Gateway. And knock on the gateway.



Rep: (4)
Hmm, but there is already a dark forest went for me: mellow:. But in any case, thanks for the tip! It may be about to try it?

Rep: (88)
Connect the router to a laptop without cable modem. Wait until the system receives an address. Then either you go to the properties of the network connections, adapters settings, and there look in the data address of the computer and the gateway address, or start-run-cmd -enter.
console typing ipconfig of Enter
see the address and gateway.
Next, write in the browserhttp: // adres_shlyuza /
If done correctly and the router is working properly, you should see an invitation in vebmordu.

Bought today this unit, I put huawei e150 modem (old), the Internet to drain firmware I by not wait modem, reflash the firmware on the topic curator - the modem begins to respond, but For connection to the Internet did not show the signal and other information (set up according to the instructions) and light on the modem was burning red, which means that it does not catch the network, although the Internet has been (a few minutes, then shut off the connection). I'm frustrated with the firmware download sitehttp://ofmodemsandmen.com/downloads.html(Can not remember which) began to sew, but she did not ask restarting the router, everything remains the same (the password which I introduced on wifi), even set up your home network through the router, the files are thrown from one computer to another, but introducing ai pi router in the address bar, not what happened (wrote that no Internet). Pomuchat computers and the router reboots the results did not give, everything worked, but in the web I could not go to the router interface. He began to pursue recovery methods using the instructions given in the header theme "More instructions for restoring routers (under partial load - the kernel must be intact)." Sew the standard firmware to recover from the cap. But the router is only the leftmost light became quite bent to burn, then light up even the most right, rotten, and all the lights lit up. When connected through a computer connection cable. He does not see, but when you click WPA / reset compounds the computer finds a button. Help to return to normal life plizz !!!

Rep: (88)
If the light the other LEDs except the power, then at least u-boot there alive and chemin de fer can be restored. If the WPS flashes during startup, then there is a lively core router and you can try to download a special recovery mode.
