When setting up a Wi-Fi network, the distance a user can connect from depends on several factors such as the type of device being used for connection, the type of router or access point in use, and the environment around it. Generally speaking, most routers are able to provide coverage up to about 100 feet indoors and 300 feet outdoors. However, this range can be reduced by obstacles such as walls and other objects that may interfere with the signal. Additionally, some devices may have a weaker signal than others due to their hardware capabilities which could also reduce overall range. Ultimately, how far away someone can use your Wi-Fi is determined by many factors but generally speaking it should cover most homes without issue.
