Guide Released to Enable 5 GHz Wi-Fi on LG C5 webOS 25 TVs by Changing Region Settings

LG C5 TVs running webOS 25 support 5 GHz Wi-Fi hardware, but certain factory region configurations, such as those for the Middle East, disable this feature. A recently documented procedure enables users to change the TV's region setting to regain access to 5 GHz Wi-Fi networks. This method involves using LG's Developer Mode and an external script to modify the region configuration without altering firmware or requiring root access. The process is intended for Windows 11 users and requires the TV and PC to be on the same local network. It involves enabling Developer Mode on the TV, obtaining the TV's SSH private key, and running a script sourced from an upstream project to read and write region settings. Users must first save the original region value to allow for potential rollback. Changing the region setting can impact tuner behavior, available apps, content store access, and warranty conditions, so caution is advised. The documented example successfully switched the region to Germany (area option 3122), which enabled 5 GHz Wi-Fi without affecting TV stability on the tested configuration. This workaround highlights an artificial limitation imposed by LG's regional settings rather than hardware capability. While it provides a practical solution for affected users, it carries risks including misconfiguration and potential service issues. Users should carefully follow instructions and understand the implications before proceeding. This development is significant as it addresses connectivity limitations without requiring hardware modifications or official firmware updates, offering a path to improved network performance for LG C5 TV owners in restricted regions.
