If your WIFI signal is constantly getting dropped by your receiving device, here are a few tips without spending any money. They save you the expense of upgrading using after-market parts like wireless boosters and high gain antennas. Most WIFI routers come with antennas that beam the signal in an omni direction and this means the signal goes out in all directions like a 3D sphere with the router sitting in the center.
The first tip, where applicable, is to make use of this default feature by locating your router in the center of your house so that the signal sphere provides maximum coverage of your 3D space. The alternative is to spend money on a uni-directional antenna that beams the signal in one direction..if you ought to have the router sitting in a corner of the home. They cost about $6 per antenna. But again, this is about not spending any money. So you might have to use an extension cord to situate your router in the center of the home. That is the ideal situation. To a lesser extent, situate your router at the level of your device which means at desk level because the signal radiates out from the router in an increasing manner and having your device situated in the center of this spherical signal is also where the signal will be strongest.
The second tip that complements the first tip or just as good on its own, is to isolate your router (and modem, since the two are attached on a short cord) from other ‘radio wave’ producing gadgets. The radio interference from other gadgets have the most impact closer to the source of your WIFI signal (i.e. your router) and has less impact once the WIFI signal is already radiating at full strength into your space. One solution is to put your router and modem in a cabinet separated from other gadgdets.
Finally, and I found this one immensely helpful is to place your router on a ‘heat sink’. A cheap home-made heat sink is just a way to elevate your router to let air into its bottom. The hot air from the router can be aired this way when most of us imagine it airing out the top from the vents on the router, a heat sink moves cooler room air under the router. A heat sink doesn’t have to be an expensive computer accessory – just elevate your router to let air pass under it.
In conclusion, what you ought to end up with, if you use all of these tips, is a router and modem somewhere close to the center of your home, in a cabinet, elevated on a heat sink, at about desk level.
