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.

If you are here for the first time or want to ask a question, first look below

Mini FAQ on the topic. Novice Questions

"Version" R3GV2 - is not more than mi4Agigabit with another label. Differences clearly. Carefully read the description and picture before the purchase. All discussions device profile topic

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
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.
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.

Yes, yes, as mentioned above, it is preferable dlna. In addition to the use of small resources are removed dlna restrictions, such as the inability to rewind the video of some formats (mkv, as far as I remember).

With the muzzle clear until it's not, but I am also in favor. But what about all the brought reset handles revisions in exports after restarting NFS? exactly what happens in paravan. We have to climb in the startup scripts.

I have to padavan from Linaro not want to be mounted ext4 disk. I formatted in ubuntu and in padavan oninstructions from wiki.
At onethe forumI found a solution.
Everything is done by means of firmware
mkfs.ext4 -O ^ metadata_csum, ^ 64bit -b 4096 -m0 -L Label / dev / sdXY

Here -L Label assigns the label "Label" disk. You can specify his or removed altogether.
/ Dev / sdXY - your drive. XY instead of by letter and number.

I also have a router not mount ext4, formatted in Ubuntu. Otfarmotirovat in windows prog eassos partition guru, everything works.
WD My Passport 1 Tb EXT4:

What is the speed on the exFAT? In padavan Linaro, it is enabled by default exFAT?

Windows 10 18.03 did not see the router on the network, it was necessary to be included in the SMB 1.0 components.

This is not a bug but a feature Leda 18.06 if you change the ip through the web is given 30 seconds, the interface is to confirm if unable to confirm that the router does not apply the configuration assuming that the connection to the PC is interrupted (like there are in Windows when you change the resolution of the monitor when suddenly everything goes off so as not to remain without monitor and do not dance with a tambourine). There are two options: either edit the config via ssh; or catch perepoluchit ip from the router, change the ip in the browser and confirm the changes within 30 seconds. If perepoluchit not possible to write by hand from the specified subnet. I hope clearly described.

A pair of small tips when working with file servers.

1. It happens that when you connect SMB balls in the windows files and folders that should be hidden, somehow visible. For example $ RECYCLE.BIN, lost + found, etc.
In this case, the option will hide files in smb.conf. He writes in the section with the balls options. like this
[Backup]
path = / media / Backup
hide files = /$RECYCLE.BIN/desktop.ini/Thumbs.db/~*/lost+found/


2. It is useful for those who use the NFS server on padavan as a media server instead of DLNA. I just watch movies on your TV via NFS.
The fact that the NFS server on padavan does not have any settings and just rassharivat in all existing partitions network with all its contents, which is not always necessary. Also customers (TVs and other players) are not able to mount some directories and see all the rubbish.
I solved this problem since. In Personalization - Scripts - Run after the full launch of the router recorded the following
# Do a small pause of 10 seconds to start the NFS server could
sleep 10
# Erase all NFS server settings that are automatically enrolled
cp / dev / null / etc / exports
# Inscribe your settings (specify the directories that want to share the)
echo "/ media / Video / Video 192.168.1.0/24(ro,no_root_squash,no_subtree_check)">>/ Etc / exports
# Tell the NFS server to reset all old settings and apply the new
exportfs -r

After that, click "Apply" and reboot the router.

Yes, you can. Only there are a couple of differences.
NTFS volumes are not automatically rassharivat. That is, when mounted NTFS partitions and turned the NFS server file / etc / exports will be empty. Therefore, in the above me above script does not need to be cleaned / etc / exports.
