Update your gadgets
Whenever you make changes to your Wi-Fi network, there is a chance that your gadgets could be kicked offline.
To get a laptop back online, go to Control Panel>>Network And Sharing Center>>Connect to a Network. Find your router's new SSID, enter the new password and connect.
Security tip: Did you know that criminals can also piggyback your network to spy on you using your own webcams? This is why we recommend cameras with built-in physical privacy shutters like Simplisafe's security cameras. With these types of shutters, you can block the lens completely whenever you need your privacy.
For a smartphone or tablet, go to your Wi-Fi settings and select your network SSID from the list of available networks. Then enter your new password and connect.
If you have a desktop connected to your router with an Ethernet cable, these changes won't affect it. You can also connect a laptop to your router with a cable to change the settings if something goes wrong and you can't reconnect to the router wirelessly.
For other gadgets like smart TVs, streaming video boxes and game consoles, their manuals should walk you through updating your Wi-Fi settings process.
Some routers and gadgets have WPS, or Wi-Fi Protected Setup. That means you just need to push the WPS button on the router and the WPS button on the gadget at nearly the same time. They'll do the setup for you.
