Assuming that you use your tablet or smartphone in many places around the house, the best spot for a wireless router would be the center of your home with a clear line of sight to your device. If you’re living in a place with two levels, placing the Wi-Fi on top of a first-floor cupboard can help boost coverage for the second level. It also helps if the router is not near any other electrical appliances.
Maximize spread with the ‘L’ Formation
If your router has two or more adjustable antennas, rotate them perpendicularly to form an “L”. This is because radio reception is stronger when both router and client device have the same antenna orientation plane. Since you cannot always control antenna orientation for devices in your home, pointing your router antennas both ways will help to maximize radio reception.
MAKESHIFT soda can Satellite Dish
Here is a cheap yet nifty trick to “help” focus the Wi-Fi signal. Wash out an empty soda can and use a pair of scissors to cut the can’s bottom away. Proceed to cut the can lengthwise on one side until you reach the top, and cut just enough of it so that you open can out into an aluminum sheet. Place your little satellite dish over the antenna by looping into the ex-drinking hole.
RESET Your Router periodically
Similar to many tech support problems, a reboot can give your router a break, clear up memory, and get it back to its best condition. To do that, unplug your AC/DC connection to your router
after safely turning it off. Wait for the router to fully discharge – the duration varies anywhere from a minute to five, so find what works – before turning it back on.
