Why's he talking about internet here?

Although I can't be certain, I think "go home ... high-speed internet" is talking about the actions he takes to isolate himself from others, so that he can be alone in his sadness and loneliness. It sounds as though he'd prefer to go home to be alone and go online than to be outside with others. It does feel a bit random to mention "high-speed internet" suddenly, but if you consider the rest of the lyrics, it probably is referring to his isolation from the world.
