The HG8247W5 is a dual-band (2.4GHz & 5GHz) Wi-Fi 5 (802.11ac) ONT. Unlike retail routers, its firmware is strictly tied to the Internet Service Provider (ISP). Updating with incorrect firmware leads to a hard brick (non-recoverable via recovery mode). There is no public generic firmware; updates must be pushed by the ISP or extracted from a working unit via JTAG/TTL. Hg8247w5 Firmware Update
