Could you be a bit more specific?
The 10 laptops that come to you - presumably you've had to do something to get them to connect wirelessly again? Otherwise in just over 2 weeks you will have none working wirelessly at all?
Assumptions; all are Windows and not Apple laptops. All APs are far apart from each other to not cause interference/cross-talk of any sort.
Your wireless network has some form of encryption and laptops are all set to only connect with it as the only preferred infrastructure network, automatically.
There are no sources of micro-wave generation near to the laptops/APs which are activated when failures happen.
