HP Pavilion Dv6 Networking :: Wireless Device Is Not Working

I will start out with my laptop's system information (and I am typing this on a cell phone)It is an HP Pavilion dv6 Notebook PC with product number - B3K21PA#ABG. Serial number is 2CE2201C96. I have a Broadcom 4313GN 802.11b/g/n 1x1 Wi-Fi Adapter according to my device manager. I have recently changed my ISP and the wireless router they have provided is the Linksys E1200 model.Now, on to the problem - after a prolonged internet use (skype call or playing internet games) my laptop just stops giving me access to the internet.

And I say it like that because the internet connection icon shows that I have network access and internet connection but none of my software or browsers are able to connect to the internet. I have tried updating the driver (both by checking driver updates and by downloading the drivers manually). I have also tried system restores and everything else I could think of, short of actually doing a factory reset on the entire thing. And I should also mention - although this issue has occurred several times now since I changed ISP (and yes, I called them about it too), this current time seems to be permanent since it has been hours and it is still not working.
