Toshiba Satellite C55-A-1NV Network Card Disconnects Wifi with D-Link DWR-116 Router: How to Fix?

Hello,
Every few minutes my wifi is disconnected and the programs that I use automatically jam and pop up with "no answer". After some time the connection comes back, but not always and then I have to reset the network card. Other laptops that do not have this problem are connected to the router, but for me this problem only occurs with this router, with others there is no problem. Also no problem with a cable connection.

Windows 8.1

Hello.
As for me, this is a problem with the wireless card drivers. I had the same. Try uninstalling its driver and installing the original Toshiba dedicated to your hardware first. You can search for it by the computer model or serial number that is stuck on the bottom of the housing. If it does not help, look for a newer one in Windows update. In my case, the installation of the original driver did not help, although nothing was wrong with it 4 years ago. I used Windows update.
