How To Lock Down Your Wireless Network

If you operate a wireless network for your home or business, it's important to ward it against opportunistic hackers seeking to steal your data or hijack your Wi-Fi for their own nefarious purposes. We spoke to Steven Andrés, CTO of security consulting firm Special Ops Security, to learn about the best ways to lock down your Wi-Fi. To get started, you'll need to log in to your router's administrative console by typing the router's IP address into your Web browser's address bar. Most routers use a common address like 192.168.1.1, though alternatives like 192.168.0.1 and 192.168.2.1 are also common. Check the manual that came with your router to determine the correct IP address; if you've lost your manual, you can usually find the appropriate IP address on the manufacturer's website.
