What happens when a laptop doesn't find a wireless network?

First we turn on the laptop and then click Search WiFi to find a lot of WiFi, but why not see your own home.

So check it out now. What's the problem, look at the light cat, fiber, cable, router, and other LAN devices in the connection, if there is no problem, then we proceed to the next step.

If the above is not a problem, then there may be a problem with the router, check the router, if the router out of the problem, then reset it.

Enter the router settings, wireless network basic settings fill in the parameters, and especially the SSID number, you can reset one.

Then go to the wireless advanced settings, refill the parameters, and then restart the router after filling it out.

After restarting the router we can find that the notebook has successfully searched for this wifi, click it, and then enter the password.

And then I got a WiFi connection.
