There have been issues with iPhones and our wireless network. When iPhones are used as a hotspot they will pick a wireless channel to use. They should pick an available channel but often don't. Normal access points will pick an unused channel, but the iPhones on campus most often pick the same channel that our wireless network is using. This iPhone behavior has disconnected other users from our wireless network.
We have made some changes today (April 16'th) to work around this Apple IOS issue.
If you have difficulty using our "Campus" wireless network since this change please let me know.
