Test and configure your wifi connection

Do not know how to access your wifi management interface? This will enable you to activate your wifi connection, to retrieve the name of this connection (SSID) as well as the encryption key WPA or WEP which defines your password. You can also reconfigure these last two and filter the devices that can access your wifi connection (mac filtering).
Whatever your ISP (SFR, Orange, Free, Bouygues …), you can access this interface via the IP address 192.168.1.1 by entering it in the address bar of your web browser. Even if this technique turns out to be obsolete (you now have direct access to your wifi interface via your ISP account page), it is still possible for you to manage your network (wifi, ethernet or USB) by this means.

Open your web browser
Enter the credentials provided by your ISP if necessary.
Click on the Wifi tab to access the information of your wifi connection.

Click on the Configuration sub-tab to activate your wifi terminal (just check the Active box most of the time) and change your SSID name. You can also make your SSID visible on the list of wireless networks (check also Active in the SSID Broadcast field)
Change channel (Channel drop-down menu) if your wifi connection seems congested.
The mode, meanwhile, is automatically taken into account by your ISP.

Click Validate and go to the Security subtab.
You will be able to change your encryption key to secure your connection; select WPA2 in the Key Type field and click on the key generator that should be just below it.
Validate again.

Finally, in the Mac Filtering sub-tab, you can identify devices and limit their access to your wifi connection. To do this, you must check Active again in this category and add the MAC numbers of your devices (defined in the Parameters of these devices).

You do not have access to http://192.168.1.1?

First, make sure your wifi connection is enabled (green bars at the bottom left of your screen). To be able to test your wifi connection, you will need to protect yourself from your IP address. To get your IP, run the command prompt, which can be found in the Accessories submenu of the Start menu, or by typing cmd in your search bar.

After the command prompt has been started, type ipconfig and press Enter. Several types of connection available are displayed. Look for your Wifi Network Card (framed in red here) and locate the default gateway address.

Open your internet browser now and type in the default gateway address that will take you to the management site of your Box.

Arrived on the page of your box, it remains for you to choose the best options for the Wifi (opt for interfaces 802.11n which offer a better flow), the channel of the box used, the mode of encryption of the wifi as well as the wifi key requested to connect.
