Why does the laptop see Wi-Fi networks, but cannot connect to them?

Question

Iron

There is a brand new Lenovo G50 laptop, Windows 10 is installed on board. The situation is this - it sees many possible wireless networks, but cannot connect to any ... it writes "Cannot connect to this network." I made an access point from the phone - the laptop was able to connect. Can you tell me what could be the problem and how to solve it?

Answer 1

There are many options, for example, networks are far away. But in general, I came across a banal marriage on a similar laptop - in ss they changed the wifi network card.
Another option is crooked firewood. Especially if you read "native from Microsoft". Especially Atheros. It happens, but it happens less often. In any case, if the laptop does not connect to an exactly working network, it is an option to stomp into the service.

Answer 2

Maybe it works on a protocol that your card does not support, that is, the network is visible but it does not connect.
