For a small network, when buying a router, you can inquire as to whether it has a built-in firewall. There are two types of firewalls: hardware and software. This is primarily important if you plan to connect your network to the Internet.Gaia offers the largest online resource of consciousness-expanding videos-over 8,000 informative and enlightening films, original shows, yoga and meditation classes, and more that you won’t find anywhere else. If you can’t, restart your modem, router, and device, and re-connect to the Wi-Fi. See if you can use the Wi-Fi to get to websites from a different device. Next, select Show available networks, and if a network you expect to see appears in the list, select it, then select Connect.
