Laptop cannot seem to keep Wi-Fi connection

[sina_t97]

Hey guys, so I am at my wits end here. 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.

I have tried uninstalling and reinstalling my wireless card drivers, updating my router firmware, etc...

Please if you know of anything else I can do, let me know. I have tried everything I can, and nothing just seems to work. I am hoping it is not a hardware failure on the laptop. Thanks for reading!

Oh and also, my laptop is an HP running Windows 7, and my router is a TP-Link TL-WR841N v7

Here are the results for ipconfig/all and a couple screenshots:

The first screenshot is of my laptop (the one with the issue), and the 2nd is of my desktop which is working fine. Notice how my desktop has an entry called IPv4 DHCP Server, which my laptop does not. Just something interesting to note.

I was able to find my Windows 7 CD key and just opted to do a format and fresh install. Everything is back in working order. I suspect it had something to do with the registry and such.
