Loss of partial or full internet access on my MBP through Airport

I have the most peculiar issue with my Airport Express in Windows on my MacBook Pro. I frequently loose my internet access, but most of the time, *only in my browsers*. I can still use other protocols, such as Spotify, uTorrent, ftp acess, etc, but my http access goes down. Chrome keeps saying "sending request" in the status bar.

Occasionally, I loose all internet access on my laptop, but in those cases, my iPhone, as well as other computers nearby, are still online, both connected to my Airport station, and able to access my internet connection.

Restarting the base station allows my laptop to surf again, but usually only for a few minutes before either of the two problems above occur.

Plugging my modem's ethernet cable directly into my MacBook Pro also provides an uninterrupted connection, so clearly, the problems occurs somewhere between my laptop and the Airport station.

I am at a loss. Any ideas, forumite geniuses? 🙂
