Every network card has a unique address. To find that, simply type ‘ipconfig / all’ in your command prompt window. You will see a line called physical address followed by a series of 12 digits and alphabets separated by hyphens. Something looking like this: 00-RR-HH-67-54-HF. That is your laptop’s physical address. Enter those addresses into the Wi-Fi router and configure it to accept connections only from those addresses. Be aware that all public Wi-Fi enabled spots like airports, hotels, etc are insecure. Use them for browsing, but be advised that using hotspots for financial transactions is very insecure.
