The Lenovo g565 laptop has a WiFi Broadcom BCM94313HMG2L module. When he (laptop) appeared ubuntu stood and the module worked (displayed wifi and connected accordingly). Then it was decided to install Windows 7 Home basic x86.
This is where the problems began. The system does not see the installed module at close range (neither the device manager (display of hidden devices), nor Aida). When I try to install the driver, it writes (~ there are no available devices (i.e. the installation drivers do not see them either)). Actually the question: What a f ...? (Sorry for the expression)
Answer
The WiFi module should be displayed in the device manager, under "Other devices" (when the driver is not installed). Like an unknown device, network controller, or something like that. With a yellow badge. See if you have any unknown devices in your device manager. If there is such a device, then the driver for it can be found according to this instruction: Network controller and USB2.0 WLAN. How to download a driver and what is it?
It is possible that you are trying to install the wrong driver.
On your Lenovo g565 laptop in the front, like on the left, there is a Wi-Fi switch. See if it's on. You can turn it off and on. Hardly a problem, but try it. Read more here: How to turn on Wi-Fi on a Lenovo laptop?
Check if WiFi is enabled in BIOS if your laptop has such feature. Look for the Wireless (Wireless LAN Support) item in the BIOS. More or less like this:
It must be Enabled.
I don't think this is a coincidence. That the module could break when installing Windows 7 instead of Ubuntu. As a last resort, you can put Ubuntu back. For check.
Perhaps the article How to replace the Wi-Fi module in a laptop will come in handy.
