Internet connection drops off only on my computer?

My pc loses internet connection practically every minute. It gets limited connection until i turn off and on the Wi-Fi. It has gotten progressively worse over the past few months. I have a lenovo. It only happens with my pc and not with anyone elses in the house. It happens more frequently when more people are on the internet. Please help anyone. It is bugging the hell out of me.

Wireless by default on all Laptops are Limited Access and need to be made a permanent connection. Open network connections, then properties of the wireless and check enable. Close the menus and reboot.
