Hello dear specialists.
In general, the problem is this, the laptop (Lenovo G700) does not see Wi-Fi grids, the drivers are all there, they were reinstalled 100 times, but the problem persists.
It all happened like this ... I restarted the laptop once, it turned on, but there was no Internet, WI-FI did not catch, I tried a USB modem (via phone) - and also without success, I decided to look at the drivers, miniports and network drivers flew into the drivers (code errors 31), removed all miniports and network adapters, then reinstalled from the manufacturer's website. There was an opportunity to make a USB modem, but there was no Wi-Fi - and no.
Laptop brand - Lenovo G700
Control Panel - Network and Internet - Network Connections - empty here.

Hello. We can attach pictures directly to questions and comments.
A very strange situation. You have all the necessary adapters installed, judging by the screenshot from the device manager. Qualcomm Atheros is a network adapter (network card) and Broadcom 802.11n is a Wi-Fi adapter. And they are without any errors. It happens that they have a yellow exclamation mark next to them. Or if you look at the properties, it shows "Error 31"?
And what's even stranger is that removing the adapters from Device Manager and reinstalling from Lenovo's site didn't help.
In the control panel, in the "Network connections" section, there must be at least two adapters. Wireless and LAN connection. It seems to me that this is some kind of Windows 7 glitch.
Try again to remove those adapters that I wrote about above. After restarting the laptop, they should recover automatically.
Also try resetting your TCP / IP settings.
