Due to construction on the 4th Floor of Cory Hall, wireless APs are being removed on the South side of the floor. Consequently, there will be limited WiFi access there to all WLANs. Wireless service will continue in the area around the BSAC office and labs in the immediate vicinity to BSAC. New APs will be reinstalled once the area is remodeled and ready for occupancy again.
