How to connect to wi-fi in windows 8.1?

Question

JavaScript

In the list of connections I see: Wireless network - no connection. There are two adapters, usb and pci. In device manager, both are displayed normally. With the router, too, all the rules, other devices see it. On the seven on the same computer with Wi-Fi, there are no problems. Where to dig? Eight only yesterday set, before it had no business.
Thanks in advance.

Answer 1

efkot is right. Definitely drivers for the wi-fi adapter. encountered this many times. despite the fact that the adapter is displayed correctly in the devices and the drivers are installed by the system, wi-fi did not work, it also met with an ethernet adapter, it was treated by installing drivers from the manufacturer.
Behavior with this is usually: a) sees the network. trying to connect. but it doesn’t come out
b) doesn’t see any network
c) it seems to connect, but it doesn’t work (I met this once, as far as I remember)

Answer 2

Is the wireless network activated? Maybe you forgot to turn on the power adapter? Alternatively, reinstall the drivers.

Answer 3

There was such rubbish, do you happen to have a laptop? If so, install the drivers from the manufacturer and the software that turns them on by fn + (...), if the desktop, try the Windows "troubleshooting", and disable the airplane mode if it is enabled.
