My internet loses its connection and at the same time, and my speaker seems broken if that happens and my mouse will not be smooth as it was before it happens. It already happened before and I didnt mind it. But now, it's happening literally all the time. After startup, my connection seems okay but after some few minutes, even without me doing something, my laptop will just lose its connection. It says that it is not connected and connections are available, but if I check if there are connections where I can connect it shows nothing. Even if, there is actually a wi-fi connection where my phone and other laptops connect. They dont seem to have problem with it. Just my laptop.

After that happens, I usually restart my laptop but I discovered that troubleshooting it would somehow repair the problem, but not all the time. It says that restarting my wireless adapter do the job.

Are there any long term fix? I mean that could last long or totally erase the problem?

I have Atheros AR5B97 Wireless Network Adapter and Microsoft Virtual WiFi Miniport Adapter, both enabled.

On the services, I have Wired AutoConfig and WLAN AutoConfig on Automatic.

Aspire 4750, Windows 7 (x86)

This sounds like the hardware itself is to blame. I also have found Atheros to have a great deal of problems including causing the Windows 8.0 to Windows 8.1 to basically fail hardcore. Are you using the current version of the driver and do you have access to some other wireless adapter? The problem could be you router if the behavior is consistant. –  Ramhound Nov 1 '13 at 15:45
