Two changes to the MSUnet wireless network are taking place on July 19, 2014. At that time new IP ranges – 35.20.0.0/17 and 35.22.0.0/17 will be added and 802.11b clients will no longer be supported. Please note, one or both of these changes may require you to take action. New IP Address IT Services will add new IP ranges to MSUnet 3.0 and MSUnet Guest 3.0 on July 19, 2014. The new addresses are 35.20.0.0/17 for MSUnet 3.0 and 35.22.0.0/17 for MSUnet Guest 3.0. Please update your firewalls accordingly to allow traffic from these ranges if desired. These additions to the wireless network are in part to support the expansion of service in the residence halls. 802.11b Wireless Disabled After July 19, 2014 IT Services will disable the 802.11b protocol. Any device that relies on this protocol will no longer work. While the number of devices affected are few, IT Services will work with those individuals to find solutions to any problems this change may cause. This protocol is being disabled to improve wireless performance as 802.11b slows down the network campus-wide. If you have questions about the upcoming changes to the wireless network, please contact the Support Desk at (517) 432-6200. -- Lisa Besko Wireless Team - ITServices Michigan State University
