From 2af07eb85393689a74d32d6211663a0e5ec02a01 Mon Sep 17 00:00:00 2001 From: Luis Mita Date: Wed, 22 Nov 2023 15:13:04 -0400 Subject: [PATCH] mediatek: add support for Confiabits MT7981 Confiabits MT7981 is a Wi-Fi 6 router based on MediaTek MT7981. Specification: - SoC: MediaTek MT7981B - CPU: 2x 1.3 GHz Cortex-A53 - Flash: 128 MiB SPI NAND - RAM: 256 MiB - WLAN: 2.4 GHz, 5 GHz (MediaTek MT7976CN, 802.11ax) - Ethernet: 4x 10/100/1000 Mbps MT7531AE (3xLAN, 1xWAN) - USB 2.0 port - Buttons: 1 Reset button, 1 Mesh button. - LEDs: 7x light-blue, 2x warm-white - Serial console: internal 4-pin header, 115200 8n1 - Power: 12 VDC, 1.5 A MAC addresses in stock firmware and in this commit: +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | WAN | 00:0c:43:xx:xx:e1 | label+1 | | LAN | 00:0c:43:xx:xx:e0 | label | | WLAN 2g | 00:0c:43:xx:xx:e0 | label | | WLAN 5g | 02:0c:43:xx:xx:e0 | | +---------+-------------------+-----------+ The label MAC was found in 'Factory', 0x4 Installation: The stock firmware is OpenWrt-based. If you can reach LuCI or SSH, just use the sysupgrade image with the 'Keep settings' option turned off.
