Message: On Monday, April 13 from 5:00 - 6:00 a.m. PT, the ITS wireless team will be upgrading Wireless controller RES-M-CW9800-80 from IOS-XE 17.15.4d to 17.15.5. ResNet wireless clients in Ridgewalk Living and Learning (Residential Buildings) may experience a brief disconnection during Access Point failover. Devices will reconnect automatically.
