Keep in mind this is all assuming you have access to your computer:

If you're on Windows 10, you should be able to right click on the WiFi connections and fix the issue by troubleshooting. You could try looking into your WiFi adapter in Windows and seeing if you need any drivers, sometimes Windows can install drives for you automatically that fix the issue.

Last Fix: (This has worked for me) if nothing works after trying everything, you can buy an external hard drive/somewhere to put your files and reset your computer, if you have recently upgraded from a different operating system (Example: Windows 8 - 10) it most likely will fix the issue if you go back to that version.

Troubleshooting almost never works it didn't work for me.
