Is your WiFi connection really too slow, and even sometimes interrupted? Rest assured, it is quite possible to boost your Wifi thanks to a few simple tips to implement!

The radical solution for a optimal internet connection, it is to connect you by Ethernet cable to your box.

If you don't want a wire, it is possible to significantly improve the Wi-Fi connection by playing on two tables.

If you live in an apartment, with many boxes installed around you, try to change wi-fi radio channel (slight frequency change), hoping to find a less crowded channel. All boxes allow this setting.

In addition, you can measure Wi-Fi signal strength in different places, with a specialized mobile application, and thus determine the best place to connect.

To assess the change, do not settle for vague impressions: objectively measure the flow of the line on a specialized site.

The settings to check to optimize your WiFi

Test the connection

Go for example on fast.com and run the test. Then note the flow rates. The higher the better.

Repeat the test after each of the operations detailed here, to verify the result.

Finding the Optimal Router Location

Not all rooms and spaces are created equal. The fact is that where you place the router can affect your wireless coverage.

It may seem logical to have the router inside a cabinet and out of the way, but that's not always the case.

A wireless router needs open spacesaway from walls and obstacles. These are not just physical obstructions; Household appliances or electronic devices operating nearby may also have an impact on your WiFi performance.

If your router has external antennas, orient them vertically to increase coverage.

And to find the places where the WiFi signal strength is the best, install the application for example Wi-Fi analyzer on your mobile Android.

Walk around your home observing the needle: below -70 dbm, the connection is poor, at -20 dbm it is excellent.

Access the settings of your wifi router

The method of accessing the wifi settings obviously depends on the brand of your box.

This happens in the management interface of your box, accessible at the following addresses:

  • Orange or Sosh: http: // livebox / or
  • Free: mafreebox.freebox.fr
  • SFR / RED: (ADSL / fiber) or (cable)
  • Bouygues Telecom: https://mabbox.bytel.fr or

With a Freebox, for example, connect to your subscriber area on the web interface (https://portail.free.fr), and go to the My Freebox section. Then choose Configure my WiFi network to access the WiFi settings.

Change channel

Nowadays we use several wifi enabled devices (internet box, decoder, computer, tablet, smartphone, printer, etc.), and often on the same channel, which causes crossings between them.

For example, when you install your router for the first time, it will automatically connect to the default channel. By not changing your wifi channel, you are sharing the same as the whole neighborhood, which can cause interference.

These interferences between devices are manifested by drop in flow and a slow connection. To remedy this, you just need to change wifi channel, for the one less used.

How to change wifi channel on FreeBox?

On the 2,4 GHz band, only 3 channels really work optimally: 1, 6 and 11. The choice of the best Wi-Fi channel is made with this in mind: the least congested will be preferred.

To change the channel on a freebox, follow these steps:

  • Expand the section Choice of Wifi channel.
  • Pass option Automatic channel to no, then choose another channel from the drop-down list Choice of channel.
  • Made Save the settings.
  • Then restart the Freebox (unplug it and plug it back in) for the channel change to take effect. Test the result with the fast.com website

Install a repeater for extended Wi-Fi coverage

A repeater is a small box that aims to extend WiFi coverage throughout your home.

Concretely, this device makes it possible to retrieve the signal from your router to retransmit it further away like a Wi-Fi hotspot.
