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.

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.

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.

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).

Can someone tell me :). In Linux, I slightly understand, and in this ambush.
Put cyberwrt, set in the router packages support USB and I can not build the automount on.
Just do not understand that it is necessary to write the fstab (and in some of them). Hands flash drive is installed. One can see it as / dev / sda1. Ntfs thought might help put the ntfs-3g, formatted USB flash drive and still zero emotion.

I wanted to get a wifi drive on ftp (samba and others like them in their native memory is not vlaziyut, and do not want to communicate with the hub)

I am seen in the link network where the firmware is all I have to eat, but the link is deadhttp://pami.biz.tm.
Maybe someone knows another source



Rep: (88)
* TJ27,
If not immediately, then in September, will try to put the firmware with a samba server automount anything that plugs into a USB port. Those. the concept is this: to connect the drive to your router and you go to him for network resources. While I was on vacation, the other "Wishlist" is accepted subject.



Rep: (296)
* hardd2007
It is not immediately :) I bought two, one plow with standard - gives with ADSL.
And second, I would like to travel / vacation: I have an iPhone and aypad have children too and without points wifi or computer does not exchange or zakinesh a stick / screw. That's like imagine a mobile Pribluda
Only important point: it should rise to the internal memory.
Oh by the way for a long time, he is a mounted drive with ntfs chews (but still not caches). Files with many points in a name generally as multiple files said.



Rep: (1)
Give please firmware to recover from this statement, which is located in the cap "More instructions for restoring routers (under partial load - the kernel must be intact)"

Prompt AMP-ta, the unit can be taken with Nat whistle 4G 3272 or 3276 and to distribute it to the Ethernet? And even if a whistle is connected BY 16db antenna on the device pull the tandem?

If he pulls the HUB, why the modem will not pull with passive antennas ...
USB extension cable is not more than 5 m, if the passive(Need to braid was multifilamentary).
they have there is marked by which they are divided into classes like
(I would recommend you to a Korean production, better quality)
I sometimes use the router to the modem and antenna-Everything is fine(Albeit without usb extension cable)



Rep: (3)
Who can faced with a partial reset the settings of the router after power?
I put the firmware "Rooter", very rare, but faced with the IP address of the router to reset the initial 192.168.0.1 to 192.168.1.1.

Prompt f ... whether it is possible to connect the MR-3020 HD or flash drive and how to do it?



Rep: (9)
hardd2007 Thank you for the detailed instructions for the firmware and configuration work whisker Islands. Now just found out that the box can work with 3272 and 3276 with 16db antenna and USB cable 7metrov (cable really nice and thick), without soldered onto the bridge. I would like to manual, wafer-parallel with the Ethernet run to Nat and heard by cable and the wafer, if it is of course possible. And yet, for some reason, not completely determined by the operator and some other parameters. Signal strength is and the name of the modem 3272 or 3276 and all.

ser.tuner thank you, sorry your post unfortunately saw when everything is connected.

Rep: (88)
I have a copy of 3272. He does not give mcc mnc codes on request and the name of the operator. You can look for non-standard, but there is no time to bother with this. I'm on vacation. If all goes well, in September posted a new firmware with new features, including especially for 3272.



Rep: (9)
hardd2007 Yes, in general, these codes are not so important, the most important level of the signal is and everything works like a more or less normal, but read the instructions on how to configure your firmware Wifi to parallel Internet heard, that it would be very cool.

Good day! Who can tell me, I can not start in the access point mode ... There is a twisted pair of PACT-TV (on their website thereconfigure the router to connect) And there is a username and password specified in the provider's contract. I do not know what to do. Or it is not technically capable of this?



Rep: (296)
* volk_a,
If you do not change the address is 192.168.1.1, to connect via putty or type of telnet.
Then set a password for the root user: passwd root (the password must not be empty).
Then connect via WinSCP or any other client SCP with the root user and set a password.
Copy the folder tmp directory on the router firmware from hats (off. Firmware pre raspakovav- need bin file)
Further from the telnet connections are command mtd -r write mr3020nv1_en_3_14_2_up (120817) .bin firmware
After some time, the router will reboot and will be available at the following address 192.168.0.254 through the web interface.
Then (if you have an Internet) can update to the latest ofitsialku.



The question is how do I set the grid:
I have Internet on twisted pair with Kerio to 192.168.0.1
What do I have to ask, what would you connect on the wifi router to Inet was not only on a computer (Easy - gateway pointing to 192.168.0.1 and all), but also an Internet router saw? Proxy authorization. The best works Ping (if also put on dns 192.168.0.1)

Grid clerical 192.168.0.x
Kerio stands at 192.168.0.1, with authorization to port 4081
I want to: sticking lace in the router and connect to a computer on the wifi, have a Net on your computer (go to the login page does not scrap) and access to the router (the router on the 'Net is also required).
I turned out the maximum that: Net on your computer is, to the router can reach only by telnet or scp (web muzzle is not present), is an Internet router does not.
The house is similar, but without the Kerio: connect to the ADSL modem and lace on the same problem: to not (only Modra ADSL modem) router muzzle Web access, etc.

I decided all questions. Only with authorization in Kerio zamorochka lacking Web browser to the router (to him on Kerio go)

Friends, please help. I have tl-mr3020 and Huawei E3276. the following problem.
The place where I plan to use, not sure 3G signal. When the modem is included in it becomes (data on a computer dialer) WCDMA mode or HSPA + and gives 3-7 Mb / s speed.
But at any moment Qual. signal decreases, and the modem switches to 2G machine. If you use on your computer, and there found the "checkbox" only 3G, but routore can not. The results of an Internet work for 5-10 minutes and fall off.

Tried to mock modem AT commands on the tool - nothing happened.

On the drain firmware not found "only 3g"
On the DD-WRT has a "Force 3G" mode, but this does not display the firmware Qual. signal 3G (ALWAYS -40 DBm), making it difficult to configure the external antenna.
OpenWRT - afraid to bet, because WEB interface is not, and the experience of torture such piece of iron is small (although PuTTY sign).

Give practical advice, like the Internet in his farm.
