Tips to protect WiFi Network
Here is, the advance tips to protect WiFi network. Whether remotely or locally, your WiFi connection is now the favorite prey of aspiring pirates.
Each WiFi network has many flaws related to its nature: the waves are easily accessible.
Thus, if you live in a city, an apartment, for example, all your neighbors will have the opportunity to access your network.
Encryption keys, from WPS to WPA2, are more and more easily bypassed. Especially if you rarely update your router.
What to do to make your WiFi network as secure as possible and protect your personal data? Start by enhancing the security of your connected devices. Here are the steps to follow.
Use a strong password for your WiFi network
Your ISP is generally doing things well and has provided you with a connection key that is complex enough to prevent hacking.
Nevertheless, if your box is in a place open to all, it is better to change this key to prevent anyone from connecting by reading the label.
Of course, avoid choosing your date of birth or 123456 to simplify your life, you will facilitate especially that of hackers.
The choice of your encryption key is essential
Your router offers several encryption protocols to secure your WiFi network. At present, WPA-PSK (AES) is considered the safest option.
It uses the WPA2 protocol which offers better guarantees to individuals, with a more complex AES encryption so 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, “Type of protection” at Free, “Security” at Bouygues ).
While in the interface, take advantage of this to disable the WPS button. Indeed, if this option saves 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.
- Advantage: in your administration interface, you have the possibility to hide the name of the network. 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 need to enter the SSID network name again, in addition to your password.
Reduce the 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 best to use only the 5 GHz frequency and ban the 2.4 GHz. The reason is simple: the walls easily block high signals.
The last point related to the signal: before leaving your home, do not forget to disable or even unplug your router.
Check from time to time the list of people connected
All WiFi boxes have a feature that allows you to check devices connected to your network. A glance will show you if all users have authorized access … or not.
The MAC address of your devices is a good indication. Feel free to blacklist unknown MAC addresses in your interface.
Keep your router up to date
Modem manufacturers, like access providers, regularly provide updates to your box to address the various known vulnerabilities.
Since the update is not always automatic, it is important to monitor the notifications of your administration interface to obtain the most recent updates.
