Laptop Wifi Windows

I have a Windows Vista Toshiba laptop and my Wifi just won’t pick up any connections anymore?
Is there a way i can fix that without paying anybody to mess with the laptop?
suggest you go to the toshiba site for your area >tech support>download, put in make , model and serial number, download and install wireless drivers, they may have been corrupt or deleted some how? They could be a zip file so download to a file or desktop, unzip (r/click>extract), find setup or .exe file and install, reboot after install, see if that solves you problem?
