Sometimes, in order to boost a wireless signal to cover all the corners of your home or office, you have to bite the bullet and invest in a wireless extender (although you can try your hand at making one, if you are so inclined— see "Wireless Witch: DIY Wireless Extenders Put to the Test" for steps).
Wireless extenders (also called wireless repeaters) wirelessly connect to an existing router and can lengthen the range of the wireless signal (repeating it) by re-broadcasting the signal. They are used to cover wireless "dead zones."
It is important to note that while extenders can extend your range, they can also halve your throughput. I suggest if you are having problems with wireless coverage, you should go for a dual-band router. Most extenders work with the longer-range 2.4GHz band. You want to pair the extender with the 2.4GHz band and reserve that band for lighter throughput tasks such as Web browsing or checking email. Keep the 5GHz band reserved for wireless devices that stream multimedia or connect to gaming consoles, smart TVs…anything that is throughput-intensive.
