The stock bootloader (CFE – Broadcom’s Common Firmware Environment, ironically) is locked down. You cannot simply upload a .bin file via the web interface. If you try, the signature check will fail, and you’ll soft-brick your device.
Some third-party firmware may not support the proprietary VDSL chipset in the HG658 V2, causing loss of internet connectivity. Preparation:
If you already own one, and you have a spare weekend, a soldering iron, and a morbid curiosity about embedded Linux—go for it. You will learn more about bootloaders, MTD partitions, and serial recovery than any YouTube tutorial can teach.
While the LAN and Wi-Fi performance skyrocket, the VDSL modem stability often degrades. Many users revert because their internet connection drops every few hours.
Gain access to VLAN tagging, custom DNS settings (DNS over TLS), and improved firewall management.
