How do I ensure that my Wi-Fi network is secure, regardless of the protocol I choose?
Ensuring that your Wi-Fi network is secure requires several steps, regardless of the protocol you choose. First, you should change the default password and username of your router to prevent unauthorized access. You should also enable WPA2 encryption, which is the latest and most secure encryption protocol. You should also set up a guest network to isolate visitors from your main network.
You should also keep your router’s firmware up to date, as newer firmware often includes security patches and updates. You should also use a firewall to block unauthorized access to your network, and consider using a virtual private network (VPN) to encrypt your internet traffic. Finally, you should regularly monitor your network for suspicious activity and take action if you notice anything unusual.
What is the future of Wi-Fi, and what can I expect from upcoming protocols?
The future of Wi-Fi is exciting, with several new protocols and technologies on the horizon. One of the most promising technologies is Wi-Fi 7, which is expected to offer even faster speeds and better performance than Wi-Fi 6E.
