I watched what happens again and noticed that upon bootup, my wireless adapter which is a D-link DWA-160 USB model, is connected. As Windows continues to complete the boot process, the wireless connection disconnects. Then I have to manually reconnect. For those of you who have the same problem, here are the steps I use: Move the mouse cursor to the lower-right portion of the screen to open the Charms menu. Click on Settings. You should see your network connection in the lower part of the Settings window. Click on it and then click on Connect. Even though I have checked the box for connecting automatically, mine disconnects after boot up and I have to go through this process to manually connect.
