I work on a medium sized grade school campus and have 120 wireless access points. I noticed that some of them do not work at all even when standing within a few feet of the AP. Its enterprise level equipment, Aerohive Networks. In general they have been fantastic.
After analyzing the topology maps its seems that the access points that do not work are in close prox. to mechanical rooms. In order to test it I moved one of the APs and it worked perfectly.
Can someone tell me whats in a mechanical room that could cause interference? Also, does anyone have any recommendations for good spectrum analyzers that will allow me to detect wifi interference. I am aware of aircheck and WIspy and an open to both but im curious as to what else is out there
