Wifi frequently drops but it says it's connected in the top right corner. [Ubuntu 12.04.2 LTS]

http://askubuntu.com – I have been getting issues trying to get wifi working on my PC. I can browse the internet for about 5 minutes then the internet drops and I have to manually disconnect then reconnect to get my connection back. I'm confused because it says I'm connected to my network but really, I'm not. If it helps, I'm using a ASUS USB-N13 b1 revision wireless adapter with RTL8192cu drivers and an ActionTec V1000H router. All help is greatly appreciated! (HowTos)
