There is no radio communication over the Atlantic because radio waves have a limited range due to the curvature of the Earth. As a result, radio signals cannot travel far enough to maintain continuous communication over the vast distance of the Atlantic Ocean.

It's important to contact your internet service provider to address these issues and potentially upgrade to IPv6 connectivity for broader internet access. **
