Connection hanging in games, is it Windows or wireless?

[AngryMerchant]

So trying to use the wireless on my laptop, I have an issue in games. In Team Fortress 2, my ping will be fine, and then probably once every minute or so, I'll get a huge hang. Like I move forward, then teleport backwards, the usual. But my ping doesn't go up, and my connection is completely fine other than that. This doesn't affect anything else. While watching streams or streaming myself, it never happens. I don't know if it's the connection being shoddy even though I'm right by the router, or something with how the computer is handling the wireless connection.

Well, now I've plugged in an ethernet cable. The LAN is recognized in Network settings but doesn't seem to appear when I check connections in the taskbar.
