The signal is constant, so you can have 5 bars of crappy internet, like 3-5 gigs is very slow. We are probably running close to 100 in the states. You can always test this with speedtest.net. So if we are anchored in Simpson Bay, we can easily pick up their signal on the boat. So, it increases your range. In Grand Case we must have had 10+ wifi signals to choose from. We would then go to the bar or restaurant, order a drink and ask for the internet code, all done
