WIFI Internet Keeps Disconnecting?

[Matt]

This is my modem http://www.amazon.com/Arris-TM822G-T.../...
This is my router http://www.amazon.com/Medialink-Wire...r...
Anyways I have about 3 laptops on the same internet, and the other 2 connect fast and never disconnect, but my laptop always says connection limited and I disconnect randomly once every like hour. Basically I disconnect randomly off the internet for like 1 minute, sometimes it will take like 5 minutes to come back. And even sometimes I have to restart my whole pc just to reconnect. And it is really frustrating where Ill be on the pc for an hour, running smoothly and then bam, random dc, yet my home pc and 2 other laptops are working fine. It is extremely frustrating ever since I got this new router since the old one was extremely slow. But I dont think it is the router, I have no idea why the other laptops dont dc, only me. And theirs does not show connection limited.

This question is for you tech support lovers out there. Heres a good chance to be rewarded for it.
