Yesterday I bought new laptop Lenovo IdeaPad 300. It was with no operating system on it, only with drivers for Windows 10. I installed Windows 7 and the internet driver for it. After that I wasn't able to search for connections or turn the wifi on. I tried to fix it from device manager, BIOS, Installing new drivers, searching for the "on/off" button (there is no button). LAN cable don't work as well.
