How to Use a Router as an Antennaby Marlene Inglis
Routers are devices in computer networking that allow two or more computers to connect or "talk" to each other. Consisting of an interface card and an antenna, routers forward data packets based on their addresses to their destinations. If your desktop computer is presently hooked up to a wired network and you require a wireless connection for your laptop, you can use your wireless router to create a wireless network by following a few simple steps.
Pick a spot away from interference of signals from cordless phones and microwave ovens. Place the router in a position in your home where it is also not obstructed by large pieces of furniture or filing cabinets. Position it on a high shelf or cupboard and as close to the center of the room as possible. Check that it is not located across from mirrors since this can lead to the signal being bounced away from your computer.
Change the channel on your router. Many household objects such as cordless phones operate on the same 2.4 gigahertz frequency as routers and the channel can become bogged down with excessive traffic; this can slow down your connection. Routers in the U.S. usually operate on channel 6 as their default, so change the channel on your router to another channel, such as channel 11 to bypass the traffic and get better and faster reception.
Check to see if your router has a removable antenna and if it does, detach your old antenna. Replace the antenna (most routers are equipped with an omnidirectional antenna that provides a uniform signal) with a bi-directional Wi-Fi antenna. These types of antennas have the ability to strengthen the signals while eliminating unwanted ones.
Place your router away from radiators since in winter the heat from the radiators can disrupt the Wi-Fi signal.
