wifi is not working windows 8.1

[kt2115]

I have Windows 8.1 pro installed.I was using wifi on this laptop everything was working fine. However recently I see that Wifi is not working though it shows me the SSID of my network which I used to use and also SSID of neighboring networks.(That means wifi chip on laptop is able to scan the wifi signals and hence it is working). The same router from where all other Mobile,Laptop,Tablets at my home are working are able to connect to the wifi network.Only on this laptop I am facing this issue. What can be a solution or what should I try.I have tried steps listed here http://www.fixedbyvonnie.com/2013/10/how-to-fix-limited-or-no-connectivity-wi-fi-issues-in-windows-8...

Though I have not changed any of the default settings only steps listed on above blog I tried to resolve the issue.However it has not worked. Also Pressing Function+F12 on laptop does not have any effect. The light on F12 key is always on. Though it is possible to switch on/off the wifi from Windows 8.1 Charms bar.

What should I check?

Hello, and Welcome to the HP Support Community!

While it may not sound logical, I would highly suggest you reboot your router.

Internet forums for any make an model of devices that use wifi are full of similar posts - "all the devices in my house are working except [my device]"...

Just another step that eliminates 50% of the possible cause!

Yes I have tried that also rebooting many many times the router still my laptop has not been able to connect to wifi of network.

I noticed today a Windows Alert message came in bottom right corner of screen that says to install the bluetooth driver. Let me make it very clear I have not uninstalled any of the device driver. I don't like to touch any device driver software. The message gave a link to download the Bluetooth adaptor driver from here http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=us&lc=en&softwareitem=cp-114431-1 so I downloaded and installed but even then it did not help my problem.I could not get back the wifi.

Please see the snapshot as it appears on my PC

 I purchased an external USB wifi device that solved the problem.  The the wifi card on laptop is working fine but for some unknown reason it is not able to connect to the home wifi router.http://www.snapdeal.com/product/leoxsys-150-mbps-nano-wifi/1179610?utm_source=earth_feed&utm_campaig...
