The IT Support Centre may have disabled your WiFi because you have a virus.
Due to the nature of wireless signals, which are affected by barriers such as walls, bookshelves, elevators, etc., it is difficult to give a guaranteed list of rooms where wireless coverage will work. All areas now support the IEEE 802.11ac standard.
To request an enhancement to wireless coverage or capacity in a particular area, please contact the IT Support Centre.
