Instructions and useful information
All actions performed with the router you do at your own peril and risk. When using custom firmwares, it is useful to have a USB-UART TTL 3.3v adapter

When installing firmware via Breed, pay attention to the choice of section and additional steps in the instructions.
Currently, the memory markup for unification has two cores (0x200000 and 0x600000).
From the first work: runoff, build OpenWRT frommogvai, PandoraBox and AsusWRT.
From the second: stock, original OpenWRT and Padavan.
Ignoring the correct choice of the kernel leads to the inability to start the firmware, problems in the work and failure of the update through the web interface.

Are there differences between "international / European" and "Chinese" versions of xiaomi routers
The difference is only in the plug of the power adapter and the pre-installed firmware, there are no other differences
I bought a router. Should I change the firmware?
Not worth it yet. Read the cap and topic, assess your needs and capabilities, the answer will become more obvious to you.
How to bind a router to your xiaomi account?
  • At initial setting, the plugin-locator should bedisabled .
  • You must be registeredxiaomi accountand installed an application forandroid, iosorwindows
  • The router must have access to the Internet (for example, wan xiaomi is connected to the lan of another working router)
  • The device from which the binding is made must be connectedonly to xiaomi router network.

    In some cases, it is necessary to make a full reset with the reset button or try binding from different devices (phones, tablets, computers). All the above conditions must be fully met.
What is the difference between firmware, which one to choose?
Stock
  • The router comes with a "stock" firmware. There were no firmware with English for this router, no, and, practically guaranteed, it will not, but there is no fundamental difference between the "English" and "Chinese" versions, except for the presence of English in the first and more frequent updates of the second. Versions for developers also do not carry significant differences from the usual except for access via SSH.
  • The firmware is based on OpenWRT, but has very limited functionality, so if you need IPTV, a media server on the router, ipv6, bypass blocking, advanced network settings, connecting usb modems and printers, full torrent clients and other amenities, look in the direction of alternative firmware.
  • The miwifi app and the rest of the xiaomi ecosystem only work with stock firmware.
Padavan
  • Stable, high-quality and smart firmware, covering almost all possible needs of the ordinary and advanced user, having an interface in Russian.
  • It features convenient and clear settings.
  • There is support for multicast IPTV (Rostelecom, Beeline and any others), ipv6, hdd connection (including several), dlna media server, work with usb modems, printers, other usb devices, bypassing locks, downloading torrents, scheduler, launching custom scripts, installing additional packages from Entware and more.
  • Of the minuses, the difficulty of self-assembly.
  • It is possible to download the finished firmware
Openwrt
  • Known fresh kernel firmware from an international development team. Covers all possible standard and non-standard needs, incl. advanced users.
  • There is support for multicast IPTV (Rostelecom, Beeline and any others), ipv6, hdd connection (including several), dlna media server, work with usb modems, printers, other usb devices, bypassing locks, downloading torrents, scheduler, launching custom scripts, installing additional packages.
  • From minuses - the complexity of self-installation of the packages and settings. Sometimes behaves not stable.
  • There is an opportunity to download ready assemblies from updated posts in this topic.
The router cuts speed, problems with range and stability, what to do?
The first step is to understand the reason:
  • If problems are observed whenwired connecting:
    - Check the speed by connecting the provider cable directly, bypassing the router.
    -Check the number of wires in the cable and the quality of crimping of the connectors, in case of doubt, check on the other cable / replace the connector.

  • If problems withwirelessly connecting:
    - Check the settings set in the router and clients: region, range and width of channels, version of the communication protocol, support on the end device (relevant for 5 GHz).
    - Analyze the broadcast and select the least loaded channel.
    - Check the speed whenever possible on multiple devices.
    RWhen the air is loaded, far away from the router, there is interference from other devices (microwave oven, bluetooth device, etc.), the speed will always bemuch Below the maximum possible, these are the laws of physics and the principle of wifi.
    The range of action and penetrating ability of a 5GHz signal is noticeably lower than 2.4, this is a feature of the technology, and not a problem with your device.
    -In rare cases, it makes sense to check the reliability of the contacts of the antennas and the radiator on the router board by disassembling the device case.
    SpeedTest and similar online services are not reliable indicators of speed. The real speed can be found either with the help of iperf or a test download torrent with a large number of distributors. Mobile devices due to limited computing resources and, in some cases, rigid fixation of a narrow channel are also not always able to display real results.

Should I connect the 2.4 and 5 GHz networks into one and how to do it?
On the stock firmware there is a separate switch in the settings, for any others it is enough to set the same network names and passwords.
However, there is no full-fledged algorithm for working with interconnected networks on any firmware, so the client will choose the connection point himself, and there are no guarantees of the adequacy of this choice:
in the overwhelming majority of cases, the 5 GHz network will be connected to the last even with a weak signal if it is initially selected by the client, and, conversely, the client is unlikely to switch from 2.4 to 5 if it is already connected to it.
thereforeit is strongly recommended to abandon this feature and use separate networks
What is the Breed loader? Do I need it?
The bootloader in a router is similar to bios / uefi for a computer or recovery for a phone: it is he who is responsible for the low-level initialization, repair and download of the main firmware.
If you plan to use only stock firmware, you will hardly be useful, but installing third-party firmware will be your guarantee of security, ease of migration and updates. Therefore,highly recommended before any manipulation of the firmware install Breed: it is primarily in your interest.
  • The stock downloader has the ability to recover only via usb flash with the original firmware image.
  • The bootloaders built into Padavan and OpenWRT allow you to connect using an usb-ttl uart adapter and restore from the command line.
  • The Breed loader allows you to connect over a normal twisted pair, has a graphical interface (including in Russian when using the plug-in), ample opportunities to configure, change system settings, firmware and create backup copies.
I want to connect a modem / printer / ... to the hdd / usb router, will it work?
On the stock firmware, only drives will work, everything else is only on Padavan and OpenWRT.
  • All common file systems, disks are supported.any volume.
  • With a 99% percent chance, your usb modem will also start up without any manipulations, but using and setting up is much more convenient in the "hilink" mode, look for details in the profile topic of your device.
  • Printers will work in one way or another. There is no WPS on the Padavan firmware, use the manual configuration of the network for the printer using the manufacturer’s utilities on the computer.
Can I connect multiple devices to the router via usb?
Yes, there is such an opportunity. Be it several identical or different devices: hdd, flash drives, modems, printers, etc., get along well together.
Only restriction : devices should have enough power. therefore highly recommended Use a quality usb hub with your own power.
How to upgrade firmware? (any)
Two absolutely universal ways that work on all firmware:
  • Through the regular update menu in the web interface and the file with the new firmware.
  • Through the Breed loader with installing the firmware in the desired section in accordance with the instructions.
Nuances of updating builds and versions of OpenWRT, setting autoboot flags to breed and otherspecify in the instructions on which you originally installed the firmware
How to upgrade from one firmware to another?
The easiest and the correct version, first install Breed bootloader (if not already selected), and then install the new firmware through it (sectioninstructionshats)
The router is unavailable, the front diode is off.
First check the power adapter, it should have 12 volts at the output under load.
Connect to the router via LAN and check the resulting IP address:
-169.254.С….С… - automatic windows range (the router did not issue IP),
-192.168.С….С… - received from the router, try to access its web interface.

If the adapter is OK, but the front diode is off, there is no wifi broadcast, no LAN access: the area of ​​the NAND memory loader is corrupted, and the option is only 2:
-Vypivanie memory chip and firmware on the programmer (easier in terms of service, because programmers cost from $ 100-150)
-Transition to NOR (SPI) memory(costs in the range of $ 5)
After switching to SPI, there is also the possibilityrestore native NAND memory
The wrong partition was selected when flashing through Breed, what should I do?
It is enough just to go into the breed again, write the firmware according to the instructions in the desired section and, if necessary, specify the boot section by adding the autoboot rule, again in accordance with the instructions. No other action is required.
How to return / update the firmware if the drain is installed Breed
To do this, go to Breed bootloader firmware to flash the drain in both sections and remove autoboot rules, if any.Few details
What are the differences between the Mi-3, Mi-3G and Mi-4 routers, which one is better to choose?
On the basis of technical characteristics and capabilities, the 3G router will be the clear winner.

I often read the branch and surprise that there are so many problems in people in Padavan. Or I was lucky with the router, or I do something wrong. Not a single dump WiFi, no speed of speed, there are no problems at all. Moreover, I also put 99 branches and 100 and 101. Now I sit on 101. Whoever observes any troubles, add the CRON task to the daily reboot of the router. My rebuilding every day at 8 am from the first launch on Padavan. Here is an example of a command (administration ->Services):

0 8 * * * reboot

Same stuff. For more than 2 years, it was sitting on Padavan with different firmware (99,100,101) and never regretted, since my 3G showed itself perfectly. Either failures, nor dumps and actually behaved like the Swiss watch mechanism. I did not put a reboot on the schedule, since I have not seen in this necessary. For several months now I have switched to asuswrt. And again I do not redeem his work. As for me, it is better than Padavana, but this is my IMHO. And by the way the reboot on the schedule is already present in the settings and there is no need to attract CRON. For long observations on the same level in all indicators with the kinetics of Giga, who works with him for a couple.

For its devices on OpenWRT prescribed the reboot such a team (for 3 at night): 00 3 * * * Sleep 70 && Touch / etc / banner && reboot

I also found a similar way (though without a step-by-step instruction) here:

You are wrong. If you connect the UART, you can see the bootloder boot, and if you do not burn a blue diode, then you have no bootloder and therefore you will not see anything on Urt and he will not help you.

There was the only option to fasten Flash memory and stitch it on a new one. But then the craftsmen figured out how to connect the SPI memory with which you can download boot, access the board and pour your firmware on Flash. And SPI memory is a very simple soldering iron level and price programmer ~ $ 10. Own at some stage it is even more profitable to stay on SPI memory due to its primitive recovery that many experimenters have done in advance.

Colleagues, I have suffered for several years from working two Router 3G access points in WDS mode on Padavan firmware
- No tricks could not raise a stable channel on 5GHz (2 Mbps with a dump in a few seconds), I had to set up 2.4GHz with a small speed (yes, I tried all the advice in this thread, and all the options for card drivers)
- In the middle of the apartment there were large delays in the transition from one point to another for a few seconds, as a result, dumps for video conferencing

As a result, tired and switched to OpenWRT
Now a real holiday

- Stable work 5 GHz (100 Mbps via iPerf)
- switch between points of approximately half acend

As configured
- on both points is enabled through the 802.11r menu (Padavan does not know how, unfortunately) - you need to press only 4 buttons
- connection between points via Mesh-Network 802.11S (Padavan does not know how, unfortunately) - configure on two deposits through the menu

so if you have two points or more - I recommend checking everything on OpenWRT, I think back will not return

Thanks to everyone in the branch, who recommends OpenWRT

Check the SSH receipt by connecting through the program to the router at 192.168.31.1

Today I sewed Padavan.
Everywhere in the instructions to flash the BREED bootloader need to enter Putty at 192.168.31.1, I tried two times no access, I changed the flash drive, it can be seen that it is stitched, but I managed to log in at 192.168.1.1 and flashed the BREED bootloader.

Setting up the Mesh-network (802.11s) with a rapid switching of clients between routers (802.11R)

theory why it is necessaryhttps://habr.com/ru/post/340140/

The instruction is suitable if you have more than one router and there is a desire to try to speed up the work of moving mobile devices (802.11R support from Apple has appeared since iPhone 4S)
MESH feature is a work on the 2-level network model, the device is inserted into the 'Shared Sweat' and all level 3 protocols work normally (for example, DHCP)

Configuration: One point is connected to the network, the rest are simply configured on the air as access points for customers and are physically located in different places.

OpenWRT version - 19.07.3

0. Before you start, you need to remove WPAD-Basic at all points and put WPAD-Mesh-OpenSSL
Go to SERVICES- Software - Update List
Next Tab Installed
Next in the Filter field, select WPAD
Remove WPAD-Basic
Click the Available tab and install the WPAD-Mesh-OpenSSL package.

1. At all points, identical settings are configured (network name, encryption, be sure to single channel) Type of 'Access Mode'
Be sure to turn off the DHCP distribution, leaving it only on one device.
When setting up 5GHz - it is desirable to use European channels (36,40, 44, 48 ) - Refeat in 2018 wrote that for some reason it does not work on the upper channels, I have earned at 44

2. Decide on what range MESH will work on both (2.4 and 5 can be configured simultaneously on both (2.4 and 5), but the traffic will only go on the first time - I first detected by 2.4, then adjusted 5, made sure that Mesh works, deleted 2.4)
If points are few and many walls - 2.4 (slower, but more stable), few walls or many points - 5 GHz

3. Go to the Interfaces OpenWRT section and create a new interface (if needed 2.4 - click Add oppositeMediaTek MT7603E 802.11bgn. If 5GZH - MediaTek MT76X2E 802.11ACN. ), in section Interface Configuration. choose Mode - ' 802.11S. ', Mesh ID - enter the ID, which will be the same at all points of the network (for example 2222), Network - We put a tank opposite LAN. Go to the next tab Wireless security - choose WPA3-SAE. By installing a password (it will be common at all points and on it, the points will be connected to each other). Press Save

4. Turn on 802.11R on the wireless interface (this will allow you to quickly switch between points to customers)
We go to the WiFi settings (where we set up the network name, encryption, channel)
Below in the sectionInterface Configuration. go in Wireless security , then put a tank at the point 802.11R Fast Transition
Next, specifyNAS ID - Must be the same at all points (for example 3333)
belowFt protocol - Be sure to change on FT-Over-Air
and check that below in paragraphGenerate Pmk Locally daw worth

5. Repeat identical settings at all points (that is, everyoneMesh ID and NAS ID. must be the same at each point)

Reboot network interfaces and see the sectionAssociated Stations.
A minute later the device will appear.Mesh Point , check that he RX RATE / TX RATE High (if it costs 6 mbit - not rose) - In this case, the low speed is reloading the channel of work to faster at all points and check again

How to check the performance - put on the iPerf computer in server mode, on the iPerf phone in the client mode, launch downloading and walk around the apartment / house / site
The drop in speed should only be for a second in places where two points are visible with about the same signal level.

According to reports on foreign sites, this option works normally up to 8 points and with small brakes at 15

P.S. You can also configure 802.11k (introduced support in 19.7.2) - until manually via Edit / ETC / Config / Wireless, the management on LUCI has not yet done
