Dear all，
ITS decided to upgrade the version of AC and AP in campus during this Saturday (18/8/2018) at 9 pm, the total time of the update has been estimated around 5 hours. As the upgrade will cover the whole campus, the Wi-Fi service in the campus will be out-of-service for half an hour during the time. We are sorry for bringing inconvenience and thanks for understanding.
