How to improve the coverage and quality of our WiFi network



The object of many desire and headache for others, WiFi. The most popular connection today, which does not always go as we would like.

If there is a word that has a great importance in the society in which we live that is, WiFi. It does not matter if the place you go to is ok, it's clean, none of that today what matters is that the WiFi network goes well. Few places are left in which there is no connection point and if it does not yet exist, be quiet, you will soon have it.

How to have a good WiFi connection?

WiFi connections give us the opportunity to have almost any device without cables, but it also has the problem of being quite sensitive to the environment in which it is. So let's see how we can, at least try, improve our WiFi connection.

The position of our router is more important than it seems

It will not be the first or probably the last time, when going to someone's home find the router hidden, something ironic today, we can not be without WiFi but the device that provides it we do not want to see it.


The recommended position for our router within our home is as central as possible , so we would ensure a fairly homogenous coverage throughout the stay. If we can not place it in an area as centered as possible, we must make sure that it is at least in an area where there is good coverage, no matter where we are in the house.

An important detail is trying not to have our router inside a piece of furniture, or covered by something, or near devices such as televisions, cordless phones, etc ...


Orient the antennas well, whenever possible

There are routers, especially operator, that do not have external antennas. But if our router is one that has two or more antennas, we must take into account the orientation of its antennas, as it is quite important:


  • 2-antenna routers: It is recommended that the antennas form an L or an angle of 90 °.
  • Routers with more than 2 antennas: In this case antennas are recommended to form a W or fan.

Types of WiFi and channels


In WiFi networks there are two variables that are also important in having the best quality in our wireless network. One is the type of networks that can handle our router and another the channel in which it is operating.

WiFi networks are classified into different types, the most common being:



  • 802.11b: It works on the frequency of 2.4Ghz and has a maximum speed of 11Mbps
  • 802.11g: It works on the frequency of 2.4Ghz and has a maximum speed of 54Mbps
  • 802.11n: It works on the frequency of 2.4Ghz or 5Ghz and has a maximum speed of 600Mbps -orical- .
  • 802.11ac: It works on the frequency of 5Ghz and has a maximum speed of 1.3Gbps .

What we usually find today are usually routers with 802.11n or 802.11ac connections, if our router does not work with these types of WiFi, it would be advisable to ask for a change to our operator or replace us with our router .


The channel where our router is working is an important data if we want to have the best quality in our network. The wireless connection as it gets popularized has made us find places where, in the same channel, 10 different routers are working.

This is called a channel saturated with connections, so it is good to check in which channel is our router. If we find that it is in a fairly used one, we will only have to change it to the channel that is freer.

We have at our disposal tools to analyze our WiFi network
To know which channel is the one that is most free in the area where we are there are applications for it, but the one I recommend is WiFi Analyzer. Thanks to this tool, we can know enough information about our wireless connection, in addition to the ones we have around.

What to do if coverage does not reach all places?

It may be the case that after having positioned and adjusted our router correctly, we still do not have a coverage in conditions. If we are in this situation one of the best options is to use a WiFi signal repeater or use some home resource.

WiFi Repeaters

WiFi repeaters are devices that are located near the area where the wireless coverage descends. Thus, being within a zone with coverage, although less intense than others closer to the router, what it does is to transparently repeat the WiFi signal that comes to you. Thanks to this we can enjoy good coverage in any corner of our home.

It may be the case that our house has several floors, the ideal solution would be to place our router as high as possible, but it is hard for us to have too much in sight. So to avoid having to hang pretty close to the ceiling our router, we can resort to a WiFi repeater that works using PLC technology.


PLC technology, basically, is to use our electrical installation as a network cable, so we will not have to wire the house. Based on this technology there are WiFi repeaters, so we will only need to connect one terminal to our router and place the other terminal in that place of the house where we want.

If you're a freelancer and want to try some cheaper option, you can try the following:

Aluminum Foil Antenna: Something that is so simple that you can make with the paper of the sandwich (new paper is recommended). Thanks to this simple trick we can improve our WiFi coverage.


Windsurfer: It is an antenna that we can download from FreeAntenas , that we will print and we will cover with aluminum, soon to place it on the antenna of our router. This allows the WiFi signal to be concentrated towards a specific area.


Antenna Pringles: If we get into something a little more elaborate, in the forum Zero13Wireless we find how we can make an antenna, using a can of the known Pringles potatoes.


Watch the neighbors ...

One of the reasons why our wireless network is not going as we expected is that we have non-grateful people in our network. When we hire the internet service, the operator installs everything kindly, so far everything is fine except for the detail that we leave our router with the security and access keys that come from the source.


One of the first things to do is to change the access password to the router, which gives us the possibility to change the settings and all the settings. The other thing we must do is change the password of our WiFi network, provided we have a password too simple, the style of our phone number or something.

An EALadvise to make a password to remember, without for that reason to be sure:


  • First , we will think a word associated with what we want to put the password, in this example I will select the word NetGear.
  • Second, we will think of a number of length equivalent to the number of spaces between letters, since N and G ear has 6 spaces between the letters that form it, we will use a number of 6 digits, for example 281216.
  • Third, we will choose a symbol , for example @.
  • Now we will only have to gather all the pieces of the puzzle, interspersing letters and numbers, besides using the symbol at the end : N2e8t1G2e1a6r @


Thus we obtain a password that has uppercase and lowercase letters, numbers and symbols. With patience we can remember safe passwords, without being the typical 1234 that usually uses enough people.
