Laptop Cannot Seem To Keep Wifi Connection

Recently, due to some reason I have not yet figured out, my laptop has started bugging out with the wi-fi and connecting to my wireless connection at home. What it does is it keeps trying to connect, and sort of connects. It gets that little yellow triangle, and says Limited Connectivity. When I check the status, I am in fact getting an IP address, and everything SEEMS to be in order. On my router's configuration page, however, I cannot see my laptop's MAC address in the list of attached wireless devices. The internet does seem to work for about a few minutes every time I restart the router.

At first I thought it might have been an IP conflict issue, so I tried setting up a static IP on my laptop. Then I tried reserving an IP for my laptop through the router. Then I tried both. And while all three attempts seemed to have fixed the problem, it came back within a few minutes.
