Conclusion Firmware is central to router security and functionality. For THG3000 owners, staying informed and vigilant—applying updates, hardening settings, and planning device replacement when support ends—reduces risk. For vendors, secure firmware practices and transparent update policies are critical to protecting users’ networks in an increasingly connected world.
Not easily. The THG3000 uses a Broadcom BCM3390 or Intel Puma 7 SoC, both of which have closed-source drivers for the DOCSIS modem portion. OpenWrt currently does not support DOCSIS 3.1 cable modems as a standalone package.
Disclaimer: Router models and firmware availability vary by region and ISP. Always consult your internet service provider’s official documentation before performing any firmware operation. Unauthorised firmware modifications may violate your terms of service.
