7 tip and tricks to dramatically improve the WiFi signal and speeds in your home or office | AndroidGuys. This is a great set of tips to help the WiFi signal in your home or office. My favorites: 1 Reset the router. Just unplug it and plug it in again. Solves all sorts of problems. 2. Get a repeater to place somewhere else in the home or office. It will take the signal and double your signal area. 3. Buy a new router. These things are getting better all the time. If your router is over 3 years old, it is time for a new one. We are all dependent on the broadband Internet signal where we live and work. A little education, and you will be the hero of your household or office.
