Fixing Roku Error Code 014.50 involves a few steps to restore your device's connectivity. Begin by ensuring your Wi-Fi signal is strong and stable. Restart your router and modem, allowing them to fully reboot. In your Roku settings, choose "Network" and then "Set up connection." Opt for a wireless connection and select your network from the list. Enter the Wi-Fi password accurately. If the error persists, consider adjusting your router's security settings (WPA2 is recommended). Alternatively, reset your Roku device to factory settings and repeat the setup process. If troubles continue, contacting Roku support or checking for firmware updates might provide a solution.
