From: Rafał Miłecki <rafal at milecki.pl>
Acelink EW-7886CAX is an MT7986A (AKA Filogic 830) based access point.
It has 512 MiB of RAM, one 2.5 Gbps PoE (802.3at) Ethernet port and
on-SoC Wi-Fi.
My unit came with Mediatek's firmware (based on OpenWrt 21.02)
installed. It was possible to simply upgrade using OpenWrt's sysupgrade
tool.
Another verified upgrade method is using U-Boot (requires UART). During
every boot there is "U-Boot Boot Menu". Selecting option "2. Upgrade
firmware" allows using U-Boot's tftp client to load and flash factory
image.
