Router and modem are perfectly capable of handling higher connections such as fibre, luckily.

Unfortunately, DSL is the fastest we can currently get. Fibre is available on almost every street in my town except for mine. Houses were built too late for fibre via telegraph poles, but too early for underground fibre optics. Replacing those lines would be incredibly costly, and isn’t an option for me. A fibre company is planning on putting a telegraph pole in, but there’s been no progress on it for months.
