What internet security software are you running? Try turning it completely OFF or uninstalling it for a little while. You mentioned Security Essentials and Ad-aware - is there anything else you are running? The two above mentioned programs would not cause this problem.
You can use a program called WhoCrashed to analyze your crash dumps. Install the software, run it, click the Analyze button and copy and paste your results. It might tell exactly what is causing the issue.
Does your school use some kind of sign in mechanism to prevent unauthorized users from accessing the wireless network? If so, this would be one significantly different thing to differentiate this particular network from any other. Have they had you add any software to your laptop to access their network?
No internet security software other than Security Essentials and Ad-aware. I have tried disabling both, but the problem remained. I used to use avast! until my free trial ran out, and I switched to AVG briefly but it caused issues with my E-mail so I uninstalled it awhile back.
I installed whocrashed and have copy pasted the results below. Weirdly enough, it's recording "crashes" during times when I don't remember getting a BSOD, and during times when I wasn't using the school's internet. It also doesn't seem to have recorded crashes during times when I specifically remember getting a BSOD. So I can't speak to the accuracy of the information, but here it is:
(Note: it says to update drivers but, as I said before, I have double checked and my drivers are definitely up to date. I have also tried uninstalling and reinstalling them.)
