Incidentally the wireless was provided by the train, it wasn't the laptop on a data connection.
Currently, this is a very big topic. We are stuck with one provider only where I live. We are massively over charged because of their monopoly position, and the service we get is shocking. People all over the city are constantly looking for alternatives. We're supposed to be on 4G, but we're still waiting for anything stable and competitive with the landline ISP 'service', which can fluctuate depending where you are in the city. A few years ago they introduced a Star Rating scheme, from 1 to 5. If you paid more you got 5 stars, the cheapest was 1 star. The basic service was identical, but they didn't have enough switches for peak times, so modem switches were prioritised by stars. So if you were on 1 or 2 stars, you wouldn't be able to connect between 6pm and 8pm peak times. THEN they introduced an 'UNLIMITED' monthly data plan, which turned out had a cap on and cost me over £300 when I went over my unlimited data limit. Currently I am paying £42 a month for landline internet and the best I can squeeze from it is about 12-14Mb. A friend less than half a mile away has currently got Gigabit Fibre Optic at £50 p/m. I phoned them and my street has not made it onto any planned schedules on the FO rollout.
There is some strange alternative, which uses a small dish and uses microwave I think, but I don't know much about that?
Other than that we are all desperately waiting for a cheap stable alternative to our current provider in this city, or they get around to the £50 Fibre Optic, whichever is first really!
Sore topic, currently.
