How to improve a wireless network?
In this article I will give some tips to try to improve the quality of wireless signal in our house, in order to have a more stable network, with fewer breaks and a better debt.
1 - Place the wireless router (or access point) at the midpoint
So we can get cover more areas (bedroom, living room, kitchen, etc.) from our house, causing the signal to higher quality. If we put our access point at one end, possibly at the other end the signal strength is not the best.
2 - Keep the router away from walls, metal objects, glass, etc.
We must try to move away our WiFi router from metals, some types of floors, glass or other surfaces that are subject to interference. Equipment such as microwaves, drills, etc are also a lot of interference sources. Make an analysis of the spectrum.
3 - Replace the antenna of the router (if possible)
The antennas that come with the router are usually omni-directional signal that is transmitted in all directions. If your router is near an outside wall, 'half' of the signal will not be passed because it will be diffused out of the house (for example). In this sense we can choose an antenna with more gain (DBIS) and also directional or sectoral, focusing the signal in a place / area specific.
