There are lots of articles about how to increase the range of your wi-fi network, but there are reasons to decrease the range. Perhaps you are worried about EMF levels and their impact on your body. Or perhaps you want to stop your neighbours hacking your wireless network. So how do you decrease the range of your network? Most routers don’t allow you to change the output power of your router, but there is a way around this. A lot routers have a ‘region’ setting. This adjusts the output power of your router to match the maximum allowable legal EMF level in your country. The USA has very high power levels. Australia and Europe have much lower allowable levels. So if you live in the USA but select ‘UK’ or ‘Australia’ as your region, it will potentially lower the power output of your router to 1/10th of the level.
