Cannot find Wi-Fi Connection

[cousin]

Guys, I need your help, please. One of my laptops Samsung R425 shows the problem of wifi connection. I have installed wifi router. Two of my laptops work good after login and password typing, but my R425 does not show it sees the present connection. Could that be the problem with driver installation? There is WiFi identifier on it, but it does not work. Thanks for the help.

So, the laptop doesn't see the wifi from your router? or
It sees it but won't connect to it? or
It connects to it but you can't get the internet through it?

The laptop does not see the wifi connection, so it does not connect to it. But the settings of laptop say that it has the possibility of wifi connection.

Are you sure the wifi is turned on? Very easy to turn it off on most laptops. Have you tested the wifi on the laptop at any other locations?

 

[cousin]

Yes, WiFi is turned on. Router is on and other laptops have the connection and work properly. Could you tell me, please, how I can check the drivers? Or I should simply download the wifi driver for this model of laptop and install it?

Check first that the wifi adapter and the router support the same protocols and set up to use the same. Sounds something like the laptop is looking 802.11n and the router wants 802.11g.

Wouldn't be a bad idea to look for your wifi adapter in device manager. Make sure there are no red or yellow icons by the device, and see what the date is on the driver.

open up command prompt, type ipconfig /all, post results

look in device manager, under network adapters, is the wifi adapter listed?

I think Ketchup79 meant is wifi on your computer turned on. Most computers have the ability to either use software to disable the wireless NIC or sometimes there is an actual switch or button on the computer to enable and disable the wireless card.

Go to network settings and right click the wireless adapter. If it says "enable" on the short cut menu then click enable to turn it on. If it is on then check your computer manual to see if there is a switch to turn wifi off and on or if there is some sort of keyboard combination that turns wifi on and off.

And, some laptops have TWO Wi-Fi switches. One, a hardware switch - usually a slide switch on the side, and TWO, a Fn combo software switch. Check your manual for that.

Guys, the solution of my problem was:

1). Reinstallation of wifi driver

2). Network settings - choose adapter - enable to turn it on (as you explained)

The result - All is working now.


My personal response - thank you, guys, for that you are always here to help!
