Connect a Laptop to Ethernet and Share That Connection over Wi-Fi

Plug in your router with a power cable, and then connect its WAN or Internet port to the Ethernet jack you have available to you. Your router will then create a Wi-Fi network all your devices can connect to–you can set up your router ahead of time and its SSID (Wi-Fi network name) and passphrase will be the same when you plug it in in a different location. That old Wi-Fi router may not support the latest wireless standards and may be a bit slow, but that can be fine for temporary use. Buy a new one or grab an old one out of the closet. If you know you’ll be somewhere with only an Ethernet connection, you can always just use a bog-standard Wi-Fi router.
