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.

Put the routers and the laptop close to each other - the situation does not change: 100-110 Mbps. Tell me, really in general to take at least 170-180? Or am I "lasted"?

If I'm not mistaken, then in the repeater mode, the speed is being cut.

I am sharing manner using ddns from Yandex.
Instructions for firmware Padawan.
Accidentally stumbled upon the Internet onan articlewhere the method of connecting to the Yandex DNS is described.
Describes alsohere, Method of changing the NS record of Yandex through the Bash script.
HereDescription from Yandex itself.
What is necessary?
1.Sobstvenny domain.
2. Register it in the systemMail for domain.
3.DelegateDomain on Yandex servers.
4.ConfirmDomain.
5.Uznat current IP address.
6. recording the current IP in Yandex DNS, onpageediting.
7. Pour tokenshere, Copy somewhere.
8. Follow the editable record ID (the method is described inarticleAbove, there are screenshots), copy, save.
9.Del, for the script functioning, we need to install CURL, for this installEntware.
10. The SSH console is installed by CURL. (Below will be an example without CURL through the built-in WGET firmware )
opkg update
opkg install curl

11.Zahodim through, click "Personalize" web interface>tab "Scripts">click on the "Run after the event WAN up / down:" and in the window at the bottom of a text copy / paste the code:
ip = $ (nvram get wan0_ipaddr)
/ OPT / BIN / CURL -K -H 'PDDToken: hereAndadnotnotnailen' -d 'domain = Vashman.ru & record_id = idizapisi & Type = A & Subdomain = Subdomain & TTL = 3600 & CONTENT =' $ ip '' 'https://pddimp.yandex.ru/api2/ Admin / DNS / EDIT ';

ZDESNADOZAMENITNATOKEN replace Upon receipt of the token, vashdomen.ru replace the primary domain, aydizapisi is replaced by id tsiferki, subdomain to subdomain (www example, what will be the ns in the recording, if the domain is a subdomain of the form without site.ru, instead of www, or else that it is necessary set @ as the settings SDA-Yandex.)
12.Sohranyaem all by clicking the "Apply" at the bottom

Next, you can check by opening another browser tab with the dns records Yandex for your domain, as in the web interface "re-connect" in the "Network Map">"State of the Internet" and thus update the IPv4-address WAN.

Upgraded ip the router, upgraded and records Yandex.

I hope someone can help my user guide!

p.s. Easier and more useful to those who have already SDA from Yandex!

### The same thing using wget
#! / bin / sh
ip = $ (nvram get wan0_ipaddr)
Wget --no-check-certificate https://pddimp.yandex.ru/api2/admin/dns/edit --Header = 'pddtoken: here_ write_tes_ot_ydex' --post-data = 'domain = domain.ru & record_id = idi_Ini & Type = A & Subdomain = Subdomain & TTL = 3600 & CONTENT = '$ ip' '--Quiet -o -


p.s.2 seems the service Yandex is covered with a copper basin, as Yandex forces the SDA users to service yandeks.konnekt that such funktsianala not.
Oh, and figs with him, by Yandex, the same can be done using dnsmanager.
Links for postingsnip, snipandsnip(without any advertising, just here when registering a domain, give free use of the DNSManager service)
If you are interested, I can write, how to configure the api dnsmanager.

If I'm not mistaken, MIMO 2x2 must solve this problem. Yes, and the speed of WiFi, not the Internet, is cut. Considering that both rosters are gigabit, pull 200 Mbps for them should be a fadder. Especially not in a big house, but in a small apartment, where each point of reception and transmission is in direct visibility at a distance of 4 meters.

If for example, we take 2.4 Hz and then we distribute to 5.8Hz or on Lana, then do not enhance anything.

Further in theory:
If for example, we take 2.4 Hz and then we spend 2.4 Hz (both router 300 megabit), however, it will be powdered to 150 emigebite (in ideal conditions)

Here I fully agree, but there is no possibility to pull the cable in the apartment. All wiring is pre-extended, and the apartment is removable. And watch the wire "on the surface" - aesthetically unpleasant :). We need a wireless network.

In general, everything would also cover one router, but the angular room and the signal prevent two bearing walls that divide me with a neighboring apartment. And here the speed is already not rising above 16 Mbps per 5GHz and 35-40 by 2.4 GHz. From here and the reason to burn the repeater, which connects the main router and the computer without obstacles.

I can't connect routers. In Padavan, for some reason, the search for TD does not work (so it would be connected to the main router). Just the endless search.

I have such a "repeater on Padavan'e" did not find the network if they were without WPA support. The bridge setting is made exclusively on the driven router, the presenter must broadcast the network with WPA2-PERSONAL. Nowhere Mac did not change.
So:
1. The future repeater is in the "Router" mode, the LAN network has a different numbering with the main one;
2. Connect to it on a wire or by that Wi-Fi interface that will not be translated into the bridge;
3. On the Settings pageWi-Fi BridgeSelect the "AP-client + TD";
4. In the Kombobox "STA SID" click "Search for access points" and select the network of the leading router;
5. We enter the type of encryption and password, click to apply, convince of "the status of interfaces"that everything connected;
6. Go toPageand switch to the "Access Point";
7. In the future, we get to the repeater Web face at the address issued to him by the main router.

P.S. I hope I did not forget anything and did not confuse - I write a memory.

In general, I rolled back to stock. When connecting the railway in the same dumping conditions, 5GHz is not observed. But why such a low loading rate of torrent 52k / s is formatted in Extfat.
UPD: All the same, I decided to check and on Padavan. I changed the case on the noreney of some kind (stood before on ASUS RT-N16). The problem was shot as from 5GHz and with torrents. Case bought this:https: //www.gearbest.c...closure/pp_866790.htmlMaybe someone will warn from buying. Although it can I have so stars agreed.


Bought the same case for the disk, 5GHz disappears when connected. Thought for three hundred rubles USB3.0 testing, it did not work out, the disk had a disc in the old box to rearrange USB2.0: Beee:

Good day to all. My smartphone Xiaomi MI6 has been losing the Wi-Fi network for the second day. Router Xiaomi 3G set a month ago, the firmware is Padavan. Everything was fine until yesterday. Sport in this forum I read that in about a month, the router begins to bite. This glitch is manifested in different ways on all the devices of the receiving Wi-Fi (laptop, smartphone, TVBox).
