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.
4 - Change the wireless client card
If possible we can replace our Wireless card to include an external antenna with higher gain and so try to increase the capture range signal.
5 - Add a Wireless Repeater / Bridge
Repeaters / Bridges help increase wireless coverage in wireless signal without the need for re-routing cables. Basically this type of equipment capture the wireless signal and regenram it, expanding the wireless network signal.
6 - Change the channel
Depending on geographic location, number of usable channels varies. For example in the U.S., the number of channels is 11 while in Europe except for France (which only uses four channels), the number of channels is 13, and Japan, use is the 14 channels.
In accordance with the center frequency and width of the channels, there are three RF channels that do not suffer from overlap of adjacent channels (1, 6, 11), allowing the use of three access points (each running in a channel) inside the same physical area.
7 - Try to reduce the maximum interference in wireless
As you know, currently there are many other devices operating on the same frequencies the wireless. Where possible and equipment (router and client card) support, we can put to work in the 5 GHz band that is less susceptible to interference.
8 - Updating the firmware or drivers for the wireless card
Updating the firmware of the router or updating the wireless card drivers are always important actions because there are regular improvements and bug fixes. Much of the time the improvements enhance the performance of equipment.
Visit the manufacturer and check for updates.
9 - Where possible always use equipment from the same manufacturer
When using a router of the same brand of wireless card client, we can probably use all the 'features' of equipment. A lot of times there are incompatibilities between devices due to their design. It is very important that before you purchase a device to check whether it is certified according to the standards of WIFI. There are situations in which non-certified cards (which can operate at 108 Mbps (Super G)), simply not being able to associate with the access point.
10 - Update of 802.11b to 802.11g (and if possible to 802.11n)
The IEEE 802.11b standard defines network transfer rates on the order of 11 Mbps, it is the transmission conditions are ideal. Will be reduced to 5.5 Mbps, 2 Mbps or 1 Mbps if signal strength or interference are hampering the transmission of data. The 802.11b operates at 2.4 Ghz.
The IEEE 802.11g standard increases the maximum rate of data transmission to 54 Mbps (5x faster than 802.11b) and a range of approximately 38 meters. It also operates in the 2.4 Ghz frequency and as such is subject to interference from equipment using the same frequency.
The standard 802.11 n, has a bandwidth up to 300 Mbps and between 600 Mbps and a range of 70 meters. It operates in 2.4GHz and 5GHz frequencies. It is a recent pattern with a new technology, MIMO (multiple input, multiple output) which uses multiple antennas to transfer data from one location to another. The main benefits of this technology are the significant increase in bandwidth and range that enables.
