Restoring 5 GHz Wi-Fi on an LG C5 by changing its webOS region

This guide instructs users to change the webOS region on an LG C5 smart TV to enable 5 GHz Wi-Fi connectivity. Restoring the 5 GHz Wi-Fi is not a firmware fix, but rather a workaround for a region configuration issue. The procedure requires changing the TV's region settings and is not a hardware repair.

Before proceeding, users must back up the original area option from the TV settings. The procedure is specific to Windows 11 and PowerShell, and utilizes LG Developer Mode and the upstream lg-geolock-bypass script. The TV should remain stable after the region change, but this result is only applicable to the specific configuration mentioned.

Users should avoid assuming the correct original value for their TV and instead save the original value for reference. The guide recommends using area option 3122 for EU hardware settings groups, but emphasizes that this may not be universal and requires verification for each TV.

After changing the region, users must reboot the TV and then verify that 5 GHz networks are visible in the settings. If the TV does not behave as expected, users can attempt a rollback by restoring the original region settings. However, this rollback process has not been tested on the confirmed configuration.
