In fall 2018 we rolled out ten new Aruba access points. They mesh together and designate one of themselves as the "virtual controller." As of this writing, its IP is 192.168.4.144 but if you're on the network you can just go to instant.arubanetworks.com and it will resolve. The APs are all IAP-315s purchased from Omada Technologies.
