This commit adds support for a dual-band AX1800 wall plug manufactured
by Shenzhen Century Xinyang Tech Co., Ltd.
CPU: Mediatek MT7621A (2 cores, 4 threads)
RAM: 256i MiB DDR3 (Samsung K4B2G1646F-BCNB)
ROM: 16 MiB SPI NOR (Winbond W25Q128JVPQ)
Wired: one gigabit RJ45 port (with green/yellow non-GPIO LEDs)
WiFi: Mediatek MT7905DAN + MT7975DN (DBDC 2x 2T2R)
Ant.: four 2 dBi external antennas (two 2.4GHz, two 5 GHz)
GPIO: tri-color status LED (GPIO 13, 14, 16);
reset button (GPIO 18)
Power: 12V 2-pin JST-XH on main PCB
110/220V AC to 12V1A DC on auxiliary PCB
UART: 115200 8n1, SMD pads available on the PCB as J4
pinout is [3v3] (Rx) (Tx) (Gnd)
MAC: 1C:BF:CE:xx:xx:xx (2.4 GHz, label)
1C:BF:CE:xx:xx:xx + 1 (ethernet [1])
1C:BF:CE:xx:xx:xx + 2 (5 GHz)
Original firmware is LEDE Reboot 17.01-SNAPSHOT (kernel 4.4.198)
with a few custom packages and a non-LuCI web interface.
Telnet and SSH are enabled, requiring an unknown root password [2].
Root password is also needed to access the router via UART console,
but passwordless telnet can be enabled via a trivial web exploit [3]
and then the root password can be removed by editing `/etc/shadow`.
Installation: First upload `sysupgrade` binary via web interface at
`http://192.168.188.1/settings.shtml` and wait until getting back to
the home screen (select network to extend). The installation fails
since the original firmware uses `swconfig` and recent versions of
OpenWrt use DSA. However, the sysupgrade file is uploaded correctly
and stored at `/tmp/upgrade.bin`, so it can be written to flash via
the web exploit [4] (both `mtd -r write` and `sysupgrade -Fn` work
fine). Passwordless telnet/ssh is not needed for installation.
Alternatively, use u-boot menu to load image via TFTP.
Notes:
- Device model in LEDE is "MediaTek MT7621 RFB (802.11ax,SNOR)".
- It is sold under several names, among them are Wodesys WD-R1802U,
Fenvi F-AX1802U, and EDUP EP-2971; the Wodesys brand was selected
since it is referenced in `/etc/banner` and `/etc/hosts`, and the
PCB is marked "WD518A V1.0".
- Instead of a standard ethernet transformer, the PCB has a few tiny
SMD coils.
[1] Original firmware sets ethernet MAC to 1C:BF:CE:E7:62:1D based on
offset `0x3fff4` in the Factory partition; since this is the same
MAC for all units, whereas WiFi MACs stored at offsets 0x6 and 0xc
are unique, it was decided to use <label MAC + 1> for ethernet.
