Google Chrome "unable to access the network"?

[thediabetik]

I am using Google Chrome on a 3 week-old laptop that I got for Xmas. The internet connection was flawless - however, three days ago I began getting error messages that read "unable to access the network" at random times whilst loading a page. All I have to do to get the page to load is refresh it; but it happens so often it's maddening. It also happens whilst playing videos; the video will freeze and will be unresponsive to attempts to rewind and play it. This one's the real problem because I usually have to refresh the page a few times before the video will begin working again. I don't think my wi-fi connection is the problem, though it is possible. Any possible causes and remedies?
