> The Arcadyan WE420223-99 is a WiFi AC simultaneous dual-band access
> point distributed as Experia WiFi by KPN in the Netherlands. It features
> two ethernet ports and 2 internal antennas.
>
> Specifications
> --------------
> SOC : Mediatek MT7621AT
> ETH : Two 1 gigabit ports, built into the SOC
> WIFI : MT7615DN
> BUTTON: Reset
> BUTTON: WPS
> LED : Power (green+red)
> LED : WiFi (green+blue)
> LED : WPS (green+red)
> LED : Followme (green+red)
> Power : 12 VDC, 1A barrel plug
>
> Winbond variant:
> RAM : Winbond W631GG6MB12J, 1GBIT DDR3 SDRAM
> Flash : Winbond W25Q256JVFQ, 256Mb SPI
> U-Boot: 1.1.3 (Nov 23 2017 - 16:40:17), Ralink 5.0.0.1
>
> Macronix variant:
> RAM : Nanya NT5CC64M16GP-DI, 1GBIT DDR3 SDRAM
> Flash : MX25l25635FMI-10G, 256Mb SPI
> U-Boot: 1.1.3 (Dec 4 2017 - 11:37:57), Ralink 5.0.0.1
>
> Serial
> ------
> The serial port needs a TTL/RS-232 3V3 level converter! The Serial
> setting is 57600-8-N-1. The board has an unpopulated 2.54mm straight pin
> header.
>
> The pinout is: VCC (the square), RX, TX, GND.
>
> Installation
> ------------
> 1. Open the device, take off the heat sink
> 2. Connect the SPI flash chip to a flasher, e.g. a Raspberry Pi. Also
> connect the RESET pin for stability (thanks @FPSUsername for reporting)
> 3. Make a backup in case you want to revert to stock later
> 4. Flash the squashfs-factory.trx file to offset 0x50000 of the flash
> 5. Ensure the bootpartition variable is set to 0 in the U-Boot
> environment located at 0x30000
>
> Note that the U-Boot is password protected, this can optionally be
> removed. See the forum for more details [1]
