As a general rule, if you double the distance between the router and client device (mobile, laptop etc.), throughput decreases by one-third of its original strength. This is further affected by objects that obstruct the signal, such as walls. The key to great connectivity is to place your router in an optimal location so that all or most of your home is covered. Adding access points, or a mesh router set-up, to spread the signal further is also an excellent option.
