I am new to the world of (what I think of as) fast Internet connections. In the past my computer has always used a so-called 56Kb dial-up connection (which downloads at a steady rate of 4.6 Kb per second - I'm not joking). I just bought a new Dell laptop with a wireless card. My neighbors have fast Internet connections and 'open' wireless networks. I doubt I can resist the temptation to use their networks, but I feel this would be dishonest (and possibly illegal), so have decided to get a more modern connection. I know nothing about these connections or the sort of modem I would need etc. Can someone please explain these things to me.
