6 tips and tricks to extend the WiFi signal at home

improve amplify wifi signal home

Extending the WiFi signal is something that often requires external devices, such as WiFi amplifiers or PLCs. Fortunately, there are many tricks that we can carry out to expand the WiFi at home , and with it, its maximum range, without the need to resort to third-party solutions. This time we have compiled several methods to improve the WiFi signal.

Place the router on a high

It may seem obvious, but the truth is that most routers are not at the recommended height to give signal to the whole house.

Ideally, place the device on a shelf or mounted on a wall with the antennas pointed vertically and horizontally , in such a way that they create a 90º angle to each other. Never on the floor, on a table or together with other electronic devices.

The further away you are from walls, the better

If we live in an old house or with several years behind it, the thickness of the walls is most likely the main cause of a low WiFi signal .

Given this, it is best to place the device as far as possible from the walls. Opting for a shelf or an adaptable base can always help us , although we can also use a table as long as its height is not too low. Ideally, place the device in the center of the house or as close to the rooms where there are devices connected to it.

Use the 2.4 GHz band whenever you can

After the arrival of fiber to a large part of Spanish homes, most routers integrate two types of bands: the 2.4 GHz band and the 5 GHz band.

If the 5 GHz band is characterized by offering all the speed that the router can provide based on the contracted rate, the 2.4 band prioritizes range and signal to the detriment of speed . It is best to use the last one if we are far from the router. If we are a few meters from the device, we can opt for the 5 GHz band.

Update the router firmware or system

Although routers generally update automatically, there are models that require user intervention to update the firmware to the latest version.

Jazztel routers generally update automatically. In this case, we will not find any option that allows us to update the firmware.

To access the router configuration we will have to write the address In the article that we have just linked, we explained some keys to access several of the options that the administration panel offers.

Switch to more optimized frequency channels

The channels, better known as channels in English, are the highways of the router through which information is transmitted in the form of waves.

Like any highway, the greater the number of cars (in this case, neighboring networks), the lower the speed of movement. For this reason, changing the channel to one with less occupancy is essential if we want to increase the WiFi signal at home.


In this case, channel 14 is the most suitable to connect to the WiFi network, as well as channel 13.

Currently there are 14 channels, of which most are occupied by other WiFi networks that adjoin ours. How can we change the WiFi channel? Through the router settings ; specifically through the advanced configuration in a section similar to Channel or Channel. The configuration, of course, may vary depending on the router model.

There are routers that are not compatible with the 14 bands of WiFi.

To see the influx of the 14 channels, we can use applications such as WiFi Analyzer for mobile phones , where a complete map will be shown with all the channels and their occupation. Finally, we will choose the appropriate channel based on its influx: the emptier, the better WiFi signal we will obtain in the rest of the devices.

Cascade multiple routers

If you have recently changed companies, you most likely have two or more routers in the drawer. Taking advantage of one or several Ethernet cables, we can network several different routers to extend the signal to different parts of the house.

This method requires the configuration of both routers through the configuration panel of the two devices. In this article we explain how to proceed step by step to connect two routers at the same time. It is not a simple process, but it is more than recommended, and above all, inexpensive.
