I had an issue with my school's wifi and dhcpcd which I figured out had to do with dhcpcd -i parameter was sending it's default, and the wifi AP was
using this field to 'approve' the attaching equipment.
I changed calling "dhcpcd -d" with "dhcpcd -d -i '' " (empty string enclosed with single quotes) and it worked!
Doesn't getting all the students together to distribute the monitors confound the results as the students are
within 10 feet of each other ?
We started using DCL http://dcl.sourceforge.net/ for tracking issues with moderate success.
It seems to have been designed with help-desk tracking in mind
