This device is a 'Range extender' variant of the Xiaomi 4A router. Its identical to the 100m non-intl/chinese version as much as it can run the same firmware, differences being form factor, LEDs, WPS button and one 100M port only. The stock firmware differs significantly, being 'app managed only'. Device specification -------------------- SoC: MT7628DAN MIPS_24KEc@580MHz 2.4G-n 2x2 WiFi: MT7612EN 5G-ac 80MHz 2T2R Flash: 16MB W25Q128BV DRAM: 64MB built-in SoC Switch: built-in SoC Ethernet: 1x10/100 Mbps USB: None Antennas: 2 x external, non-detachable LEDs: 2 programmable blue/amber Buttons: WPS and reset (hidden) Housing: Range Extender / Wall wart Serial: 115200,8n1 MAC Addresses ------------- All 3 MACs are read from flash and identical to stock. Label MAC is WIFI 2G Installation ------------ No HTML UI on this device, serial console only. The serial connector is unpopulated but standard size and clearly marked. Flash from the U-Boot shell at boot by choosing (2) and flashing the sysupgrade file via tftp. Recovery/Debricking procedures of the xiaomi 4A and variants should work, but there currently is no official source for the stock firmware. Signed-off-by: Jo Deisenhofer <jo.deisenhofer@gmail.com>
