Re: Lenovo v570 network adaptor not found (for wifi and blue tooth)
It may be that a driver for your installed OS needs to be installed rather than a "generic:" one. For example, if running Windows 7 then a Windows 7 driver will work, where a Windows 8, or 10 will not.
Please include what version of OS is installed on your system, what drivers you have tried (even if failed) and where you obtained them in your response.
