Try this:
1.Right click Network and Sharing Center on the Taskbar.
2. Go to Change Adapter Settings on the left hand side panel.
3. Right click the Wifi adapter you use, then Properties the Configure. While on the General tab, see if it says this device is working properly.
4. Go to the Advanced tab. Here you will see the hidden features of your wireless adapter. These features are not the same for different wireless adapters so my wireless adapter will have different or some similar features with yours. See if any of the settings there says anything about "auto disconnect" or "power saving" then disable that. I personally have the "AP Compatibility Mode" feature which the default was "higher performance" which I changed to "broader compatibility". I believe it improved the connection. When I first had my Wifi MODEM, it had trouble connecting with my wireless adapter until I changed some of the settings listed here. I got it right somewhat by chance that I was able to connect. You might have to manually change your settings here and see if anything works for you. It restarts your wireless adapter every time you apply changes.
5. If nothing else works, you might consider installing a new driver for your wireless adapter. An easy way for that is simply go to the Driver tab next to the Advanced tab. Under the Driver tab, click the Update Driver button.
