There will be an upcoming maintenance for the Arkansas Tech University wireless system on Saturday, October 27th, starting at 6 a.m. and lasting until 7 a.m. During this time, the wireless networks in the residence halls and the academic buildings at the Russellville and Ozark Campuses may be unavailable. The actual duration of time that the wireless will be unavailable should be less than 20 minutes but the entire window is reserved. This maintenance will allow Network Services to update the security certificates on the system.
