Lenovo G580 wireless network adapter disconnecting

Hi, I have a Lenovo g580 and am constantly loosing my network connection - around 10 times an evening. I am running windows 8.1. One other thing I have noticed is that since I upgradd to Windows 8.1, it has got worse. And also I have lost all Bluetooth devices. Before I upgraded my I could bluetooth photos from my Samsung S3 mini. Now, although it shows as there and paired it disappears from the list the mnute I try to transfer. Could it be Windows 8.1 that is causing the problems?? I am not a computer expert but have managed the following:

 

The 5 little bars in the task bar, bottom right, go blank. I right click and select Troubleshoot Problems. Windows does whatever and comes back with a little window showing Windows Network Diagnostics, Issues Found, Problem with Wireless Adapter or access point.  Fixed. 

 

Anything from 10 to 30 minutes later it goes again.

 

I went to Device Manager and selected Qualcomm Atheros AR9485WB-EG, right clicked and selected update driver software. The result shows "Windows has determined the driver software for your device is uo to date.

 

I downloaded Lenovo LSC Lite Diagnostics for Wireless and ran the test at the point when it disconnected. I get this: 


2/5/2014 9:53:25 PM - Warning Wireless adapter must be enabled and connected to a network


2/5/2014 9:53:25 PM - Local Connection Test

Warning 0.05 s

 

When I let Windows resolve the problem, as mentioned above, under Issues Found I show Detection Details: I have no clue what any of this means or if it is relevant.

 

My hubby sits next to me and slightly further away from the Router and has no such problem. When my son comes home he can use his laptop upstairs and much farther from the router and gets no problems. And on my work laptop I can sit in the same seat and get no problems so it must be this laptop and NOT the router.

 

Please can anyone help? Or do I have to contact Lenovo for warranty as this laptop is less than six months old.

 

Thanks

Re: Lenovo G580 wireless network adapter disconnecting

   Same problem for some time now.  I've had the G580 for probably a year but did not experience any wireless problems until after upgrading to Windows 8.1.

 

   I've tried all these driver updates ad nauseum, including this one  - 

 http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/lenovo-g580-no...

 

   Of course, that fix did not work either and I find it interesting that there is no real acknowledgement of this problem or a real repair.  Today, I found this fix on Toms Hardware and so far, for hours, it has worked.

 http://www.tomshardware.com/forum/id-2041675/windows-broadcom-limited-connectivity-lenovo.html

 

   Good luck!
