Please provide make/model of your computer. Is it a desktop PC or laptop/tablet? Is it a self-built PC you built yourself? Or an OEM computer (Dell, Acer, HP, Toshiba)?
Laptops still come with a Wi-Fi switch, which often gets turned off if you remove it from your home and travel with it somewhere. The process of putting the laptop into a carrying case and then taking it out again multiple times can easily move the switch to the off position where you will disable your laptop's Wi-Fi and thus won't get any list of Wi-Fi networks to popup on your windows screen to connect to! Here's an example of what that switch looks like:
Other laptops, most modern ones have done away with that physical switch and use a keyboard combo of 2 or more keys to enable/disable the wi-fi radio inside of your laptop as pictured here:
Enabling your Wi-Fi switch by sliding a physical switch or using a combo keystroke will usually solve this problem. If it doesn't, then you may have anything from a failed driver from a recent Microsoft or other update on your computer, to a failed hard drive. If you get to this point, you should consider testing your hardware. You can use this free TROUBLESHOOTING GUIDE I wrote to help you available here: Windows 10 - Unclickable Task Bar

welcome to windowsforum, kay5ive … you might also review your wi-fi settings in w10 pc-settings:
pc-settings / network-internet / wi-fi
here you can choose to enable/disable wi-fi
if desirable, click "show available networks"
once this happens, an interface appears (above system-tray) …
here, you can click "wi-fi" to view all connections (within your proximity).
also … pls understand wi-fi is not inherently secure … your connection can be hacked and your pc can be compromised/exploited.
you may also consider posting screen-cap if your issue has not been resolved by our efforts, kay5ive. another suggestion would be to post your question directly to the forum of your laptop manufacturer … the forum for toshiba is forums.toshiba.com … thanks.
When you click the network icon lower right in task tray you see a choice to turn WiFi on. If connected by Ethernet but all other devices are connected by WiFi via the router, they should be visible. Did you mistakenly click the off switch on the keyboard.?
Are you phones getting online visa WiFi which would mean you have a secure network.
Did you just change your password and need to click "forget" to 'view' your SSID?
