The wireless infrastructure at UNC runs on network operating systems. Just like desktop and server operating systems, this infrastructure must be upgraded. When access points reattach to their controller, they begin downloading the new firmware and also reboot. Under normal circumstances, users can expect up to 10 minutes of outage for a given wireless access point, but it can go longer. For the purposes of this standard change, we will execute the reboots during our standard maintenance window of Tuesday through Thursday from 5 AM to 7 AM.
