Wi-Fi is a wireless network technology that allows the various devices that we use daily (computers, smartphones, tablets, television, connected objects, etc.) to have internet access, via high speed links. There are public Wi-Fi networks (accessible to everyone, often present in places of passage: restaurants, stations, hotels, etc.) and private Wi-Fi networks, which are found in individuals, and which are generally protected by a password. In the coming years, Wi-Fi 7, which promises an even faster connection rate, should equip our Wi-Fi routers.

You cannot connect to your Wi-Fi network, or you have noticed that your connection is slower than usual ? Here are several avenues to restore connection.

If your Wi-Fi network is slow

Test your flow

The first reflex to adopt when you notice a latency on the side of the Internet connection is to carry out a debit test. This makes it possible to understand what are the impacted parameters: downward flow, ascending flow, latency time (ping) ..

There are different tools (most often free) which allow you to have a precise idea of ​​the quality of your connection.

Note that if your internet connection seems slow when you visit a website, it may be a concern encountered by the site in question. To be sure, test another service that uses the Internet: if it works, it means that the website encounters a technical problem on its side.

Restart the Wi-Fi box

A solution that seems logical, but very effective ! Often, just turn off and restart the router to improve Internet connection. Some boxes also have specific buttons that allow you to activate or deactivate Wi-Fi. Check that it was not inadvertently disabled.

Move the Wi-Fi box

When you have a Wi-Fi box, it is important to place it in a strategic location to guarantee a good signal. Here are some tips to follow, if your interior allows:

  • Place the box in the middle of the accommodation, so that all parts have sufficient access,
  • Position the Wi-Fi box in height, to promote the emission of waves (which move vertically and horizontally),
  • Avoid places that reduce the propagation of waves (metal objects nearby, overly thick concrete walls, etc.)).

It is also possible to use a Wi-Fi repeater, which aims to amplify the signal of your box, in order to extend it to other parts.

Check the local offer of your operator

It happens that operators do not offer the same quality of internet connection according to the localities. In this sense, the Acerp offers an interactive card which allows you to discover the quality of a flow according to a precise location. You just have to indicate your postal address to find out which Internet access providers (ISP) offer the best offer.

If you can’t connect to the Wi-Fi network

Disable and reactivate the Wi-Fi option

If you cannot connect to your network, remember to deactivate Wi-Fi, then reactivate it again on the device that encounters the problem. This simple handling can sometimes solve connection bugs.

Forget the Wi-Fi network

If the previous method has not worked, you can also “forget” a network, to reconnect then.

  • On iPhone or iPad: meet in Settings> Wi-Fi, Then click on the symbol “I”, next to the network you want to forget, then Forget this network> Forget.
  • On an Android device: Access Settings> Network and Internet> Wi-Fi, Then click on the network in question. Then press DELETE (or the trash -shaped icon).
  • On Mac: Go to the Apple menu>System Preferences> Network> WiFi, Then press the button Advance, Choose the network concerned, and then click on the deletion button (at the bottom of the list).
  • On Windows: In the taskbar, click on the network icon, then select the Wi-Fi concerned and press Forget.

To reconnect to the Wi-Fi network concerned, you will have to enter the password again.

Restart your device

If the bug appears only on one of your connected devices, it is possible that the problem comes from it. Simply restart your device to connect to the Wi-Fi network.

Check the presence of viruses

The presence of malware can saturate the bandwidth and slow down your internet connection, or even cut it entirely. Consequently, it may be interesting to equip your devices with antivirus software, and thus ensure its protection.
