Laptop doesn't to connect to the internet?

Being unable to connect to Wi-Fi is a common issue with the Lenovo B575-1450. First, before you do anything, make sure you have Wi-Fi enabled. On your ask bar on the bottom right corner f your screen, click on the internet icon, and make sure your Wi-Fi is enabled.

If it is not, then maybe your drivers are out-dated. Consult the Drivers%20and%20Software&beta=false for the B575 for drivers for your respective operating system.

Lastly, if neither of those solutions work, your Wi-Fi card may need to be replaced.
