WT3020x - another representative of mini routers for working with modems and other peripherals. Despite its small size (smaller than Tp-link MR3020), it has more productive stuffing and allows you to quickly organize a mini network with Internet access and / or vpn connection to another network (office, home, etc.). The time of writing this text is available in two color compositions: black and white.

SSH access
It is absent in principle on the stock firmware, but there is Telnet, which does not allow transferring files to the server directly, which leads to problems with automatic firmware ... Telnet login and password:
Login:nexxadmin
Password:y1n2inc.com0755
However, the latest version of Prometheus supports firmware on the drain.
Firmware
from D-Link DIR-620 Rev.F1
Maybe someone will be interested in another absolutely working firmware from D-Link DIR-620 Rev.F1))
As usual, fill in through breed, after the first launch, we reset to factory settings. Who needs it, attaches a screen with settings for Intertelecom.

Instructions for firmware router on firmware from ASUS (mod from Padavan)
This manual is intended for those who want to upgrade to the ASUS firmware (mod from Padavan).
To go, you must have the PROMETHEUS script installed and the firmware compiled, you can read about it in detail.
Thisforum thread.
Because There is no SSH on the router, the installation of the firmware is complicated, because the creators of the PROMETHEUS script have prepared a solution that will facilitate the installation process reducing it to pressing a few buttons.
1. In order to flash your router using a script, it is advisable (but not necessary, since the script can sew and Telnet) to install an intermediate firmware on it, which will open access to SSH. Why do you need it? The compiled firmware may not fit into the section reserved for it, and then the router can be removed from the state of the brick only via the UART.
For A revision:
nexx_zero_a.zip(2.92 MB)
For other revisions (H and F)nexx_zero_h.zip(2.94 MB)
Before flashing, be sure to unpack the archives !!! The firmware is installed through the WEB interface of your router.
ATTENTION!!! This is not a full firmware, it will not give you the correct operation of the router, this file serves only to upgrade to another firmware. Almost everything is cut out of the original, you will have WIFI (password 1234567890) and an SSH server, LAN access and DHCP enabled. Everything else is removed. 2. Flash UBOOT through a script, there is no need to assemble it, it is already delivered as a finished product.
3. After that you can flash the router on the assembled firmware in Prometheus, Login / Password: admin / admin, ip: 192.168.1.1.
Instructions and transient firmware provided by the userFreize , for which he thanks a lot! :
пїЅ
You can not distribute ready-made assembly devices for companies other than ASUS;
• You can not use the script to build the firmware with proprietary modules;
• It is strictly forbidden to distribute mods, patches and parts of the code that interfere with the above conditions.
From zyxel
I want to warn everyone that the firmware, although it starts, is from a different router and causes a number of bugs. It makes sense to use only zyxel fans or people who are too lazy to mess with other firmware.
How to flash firmware from omniExplanations for facilitating the omni firmwareGet root and install packagesOpenwrt
Download firmware from the official siteMemo for the bootloader firmware on LEDE / OpenWRTWIKIModified OpenWRT by rachtPlease note that the firmware can be installed via the Web interface, but OpenWRT will not allow you to change UBOOT, and the stock downloader does not support recovery via sftp or usb. It is strongly recommended that you first flash one of the loaders, otherwise you can get to the brick.

just do not forget to unpack !
Instructions for restoring firmware: 1. Copy to the root of the first section of the USB Flash disk (usb 2.0), pre-formatted (ie, empty) in FAT16 / FAT32, the firmware image, while renaming the file to "root_uImage" (without quotes and extensions, BUT case sensitive );
2. Turn off the power of the router (pull out the power cord from the router);
3. Insert the USB flash disk into the USB port of the router;
4. Clamp the RESET button and turn on the router (we plug the power cord into the router) without releasing the RESET;
5. WAITING, the flash drive will start blinking (if there is an indicator on it), after a couple of minutes of holding, release the RESET;
5. After some time, if the indicator of the router does not change color to blue, restart it, the firmware will load. If it does not, check the USB flash drive or pick up another one.
Information unit in binary numbering system GOST 8.417-2002 GSI
bit2(bit) - amount of information 1 (usually used to denote the connection speed and the amount of information transmitted);
byte2,3 - amount of information 1 equal to8bit (usually used to denote the amount of data on the media).
1) The term “amount of information” is used in devices for digital processing and transmission of information, for example in digital computing (computers), to record the amount of storage devices, the amount of memory used by a computer program.
2) In accordance with the international standard IEC 60027-2, the “bit” and “byte” units are used with SI prefixes.
3) Historically, there is such a situation that the name “byte” is incorrect (instead of 1000 = 103accepted 1024 = 210) used (and use) SI prefixes: 1 Kbyte = 1024 bytes, 1 MB = 1024 Kbytes, 1 Gbytes = 1024 Mbytes, etc. At the same time, the designation Kbytes start with a capital letter unlike the lowercase letter “k” to designate a multiplier ten3.
Version difference
A = 4 MB flash - no USB
AD, H, F are absolutely identical devices, the only difference is in the firmware that comes from the factory with the Chinese and English interface
The base of modems for support is increased in the H version compared to F
AD didn’t feel, but I suspect that they added some dLNA / UPNP thread, and I didn’t see it on sale, and I don’t see any reason to overpay for something that can be implemented with alternative firmware (I still make backups with the stock programmer and sew everything my heart desires)
What does the F model show that at some point in time (during the merging of Lede with OpenWRT, in version 17.01.2-17.01.3) the firmware stopped loading, I suspect that they changed something in the hardware, and specifically something was namut in the core with support for the SPI interface on which the entire firmware sits
But in recent versions of OpenWRT this problem is not noticed.
I checked it very simply, two devices purchased with a difference of 1 year on native Flash-ah, the same firmware was launched on one, and not on the other.
after updating OpenWRT to version 17.01.4, the firmware compiled with the same configuration worked on both devices
