As Joe mentioned, I've seen a number of Windows laptops that will interrupt wifi for about one second in order to scan for available access points that are in the area. I generally see the blips at around 69 second intervals, but have seen some at 34 seconds as well. I'd try installing the latest drivers from the computer vendor and see if this helps.

Another issues I've heard, but never seen, has to do with IT departments detecting a rogue APs and attempting to shut them down. It may be worth contacting the school or other IT officials and describing what you are doing and your symptoms.

Finally, it may be worth checking that your AP and laptop are set to 5 GHz. This tends to be less crowded and have fewer issues.
