If global radio communications systems are disrupted, what is the alternative?

An event has occurred several thousand kilometers from the surface of the Earth. Let's assume some sort of tear in the universe has appeared, from which extra-dimensional or exotic energy is pouring out. It has affected all wireless communications globally.

1. What alternative wireless communication form exists that might survive such disruption i.e. is less prone to interference than radio waves.

Now I'm not quite certain what affect varying radio frequencies and wavelengths have on communication distance and resistance to interference, so:

2. Is there any science or science-adjacent justification for why some kinds of radio signals still work while others don't?

3. Alternatively, can providing more power to a radio transmission overcome such interference or not (and I know that's asking a lot because we don't know the precise nature of the interference, but could that make sense in some way)?

4. Finally, is there a possibility that wired communication might also be disrupted?
