Guide to Restore 5 GHz Wi-Fi on LG C5 TVs by Changing webOS Region

Addressing 5 GHz Wi-Fi Limitations

This guide provides instructions for restoring 5 GHz Wi-Fi capabilities on LG C5 televisions. Some LG C5 models, particularly those configured for the Middle East region, have 5 GHz Wi-Fi disabled by default in their webOS settings, even though the underlying hardware supports it. This procedure is a configuration change and does not involve firmware updates or hardware repairs.

Procedure Overview

The method involves accessing LG Developer Mode on the TV and using a PowerShell script on a Windows 11 PC. The process requires an LG Developer account and specific tools like curl.exe, ssh.exe, and scp.exe. It does not require root access to the TV. The guide outlines steps from enabling Developer Mode and Key Server on the TV to executing the script from a PC to modify the region setting.

Potential Risks and Considerations

Users should be aware that changing the TV's region can have several side effects. These include alterations to tuner behavior, the LG Content Store, available applications, country-specific settings, and potentially warranty or service handling. It is recommended to save the original area option before making any changes. The guide notes that selecting 'Germany' as the country resulted in stable operation for the tested configuration, but other models or firmware versions may behave differently.
