Have you noticed a slower internet speed in the past few days? Too many devices connected to your WiFi network? It’s time to be wary and strengthen the security of the network. Nothing too complicated thanks to our tip.

Wifi security hacking

Whether remotely or locally, your WiFi connection is now the favorite prey of budding pirates. Each WiFi network has many flaws linked to its nature: the waves are easily accessible. Thus, if you live in a city, an apartment for example, all your neighbors on the landing will have the possibility of accessing your network. The encryption keys, from WPS to WPA2, are more and more easily bypassed. Especially if you rarely update your router.

Lost WiFi password: what solution?

So what can you do to best secure your WiFi network and protect your personal data? Start by strengthening the security of your connected devices. Here are the steps to follow.

Use a strong password for your WiFi network

Your service provider generally does things well and has provided you with a sufficiently complex connection key to prevent piracy. However, if your box is in a place open to everyone, it is best to change this key to prevent anyone from logging in by reading the label.

Of course, avoid choosing your date of birth or 123456 to simplify your life, you will especially facilitate that of hackers. To configure the perfect password, refer to these six essential tips.

The choice of your encryption key is essential

Your router offers several encryption protocols to secure your WiFi network. Currently, WPA-PSK (AES) is considered the safest option. It uses the WPA2 protocol which offers better guarantees to individuals, with more complex AES encryption therefore less fallible. Of course, if your device is compatible, opt for the latest generation of encryption: WPA3. The latter has the best current data encryption and is the best shield against dishonest connection attempts.

To configure your encryption protocol, connect to your box interface and go to the security options (“Security mode” at Orange, “Encryption” at SFR, “Protection type” at Free, “Security” at Bouygues ).

While you are in the interface, take the opportunity to disable the WPS button. Indeed, if this option allows you to save time by automatically connecting your devices to the WiFi network, it is also a backdoor for hackers.

Hide the name of your SSID network

As for your password, the name of the SSID network is present under your box. Again, it should be changed. Better: in your administration interface, you have the possibility to hide the network name. It will appear more in the list of available WiFi networks, which will make yours much less vulnerable. Disadvantage: when connecting to your WiFi network, you will have to re-enter the name of the SSID network, in addition to your password.

Reduce signal range

Making the WiFi signal less powerful reduces the risk of hacking. This maneuver weakens the connection, so a user outside your walls will have trouble connecting to your network. The power setting is (always) done from your administration interface. Look for the “Channel” option and change the value of it.

If your router is compatible, it is preferable to use only the 5 GHz frequency and to ban 2.4 GHz. The reason is simple: walls easily block high signals. Last point related to the signal: before leaving your house, do not forget to deactivate or even unplug your router.

Check the list of people connected from time to time

All WiFi boxes have a feature that allows you to check the devices connected to your network. A simple glance will show you whether all users have authorized access … or not. The MAC address of your devices is a reliable indication. Do not hesitate to blacklist unknown MAC addresses in your interface.

Keep your router up to date

Modem manufacturers, as well as access providers, regularly provide updates to your box to address various known vulnerabilities. Since the update is not always automatic, it is important to monitor the notifications from your administration interface to obtain the most recent updates.
