How to have your WiFi network protected
Another viable option is to check if someone connects to your WiFi through a computer. One of the most recommended is Wireless Network Watcher. If you want to start using it just follow these instructions. The first thing you will have to do is download the program. Very easy, accessing the soft page and choosing the option Download Wireless Network Watcher. You can download a ZIP file with all the information about the program. You also have the option to download the executable directly.
You will see that instantly, the tool is responsible for providing you with a list of all the devices that are connected right now to your WiFi network. What you can do next, in case you have doubts about one of the equipment, is to right click on the device in question. You can see, in that case, what are the characteristics of each computer and the MAC address. This way you can detect and veto those devices that are connected to your WiFi, but are not actually authorized.
Okay, I’ve been able to verify that I have an intruder accessing my WiFi network. What can I do from now? One of the first measures is to block unauthorized devices. But for this you will have to access the administration panel of the router. You will need to configure MAC filters. If you do not know very well how to do it, we recommend to ask for help to an expert. Or your own service provider. A call should suffice. If you have enough knowledge, you can do it yourself.
Enter the IP address of the router in the address bar. You will also need to include your username and password. Within the management panel of the router, you will have to search the filters by MAC. If you already have the MAC address of the intruder that is stealing your WiFi (you can copy it from any of the two tools that we have provided above). Entering this address will block your access. Another interesting option, if you do not usually have visits that connect to your WiFi, is to filter only the MAC addresses of your devices. So the rest cannot access.
In addition, we recommend you have a well-protected WiFi network. It would be interesting to note the following: Use a more advanced WPA2 security system. This is a more secure encryption system. Make sure your router is well configured.
Change the default password. This and other actions can be carried out directly with your provider who also has access to the guts of the router. Make sure you have a minimum of 12 characters, in which uppercase, lowercase letters, numbers, and symbols are interspersed. Modify the name of the WiFi network. It is that they cannot identify it and that logically is not related to the password that you have chosen.
Change the password to access the configuration. It is convenient to modify it, because it gives direct access to the configuration of the router. Turn off the router when not in use. You can do it at night or if you leave, home and nobody will use it. Of course, you should also turn it off if you are going away for a few days at home or going on vacation.
