Identified - Situation:
iPads at CRMC are currently unable to connect to the CRMC SecureNet Wi-Fi.
Background:
A new ISE server was installed with an updated certificate, which caused the iPads to lose connectivity to the CRMC SecureNet Wi-Fi.
Assessment:
iPads must be connected to the network via a hardwired connection in order to load the new certificate.
Recommendations:
Please submit a ticket to the Cerner Help Desk, and IT will resolve the issue as quickly as possible. Alternatively, you may bring your iPad(s) to the IT office located across the breezeway by Distribution. Please ask for Vanda Seibert.

Identified - Last night, a certificate breakage in the employee WiFi networks occurred impacting laptops. Affected devices may currently be unable to connect to the MU Health Care, UMHWirelessII, or TigerWiFi networks.
A fix was implemented, but laptops will need to connect to the wired network to retrieve it. If your device was impacted, please take the following steps to resolve:
1. Connect your laptop to an onsite wired connection via an Ethernet cable connected to a wall port or a docking station connected to Ethernet
a. If you are offsite or a wired connection is not accessible, instead:
i. Connect to a non-employee WiFi network like a cell phone hotspot, your home network, or the Guest network (other networks may be preferable to Guest because it’s very slow)
ii. Open Cisco Secure Client and connect to the VPN
2. Hold the Windows key on your keyboard and press R to bring up the Run dialog
3. Enter gpupdate.exe /force and press OK
4. A black window will appear stating “Updating policy…” as it retrieves the updated certificates
5. Once that completes, the ability to connect to the employee WiFi networks should be restored! If still produces errors, please restart your computer and test again, then contact the help desk at 573-884-4357 if still not resolved.
If you're at the CRMC campus, you can take your laptop to room 1145 where an MU port is available to complete this process.

DNA Spaces Connector Upgrade Aug 4, 2026 09:00-11:00 CDT
S Situation
MUHC Networking Team will be performing an upgrade of the Cisco DNA Spaces Connector 8/4/2026 @ 0900->1100.
________________________________________________________________________________
B Background
Cisco Spaces Connector supports location services for many devices.
_________________________________________________________________________________
A Assessment
Most notable applications affected are MobileView, HUGS, and Staff Durress.
Temp Monitoring:
• Monitors will continue to send temp data but physical location reporting of devices cannot be trusted during this time.
Staff Duress:
• Instant Notifier will continue to alert on duress events, but the location data should not be considered reliable at this time. Physical panic alarms are not affected and will function normally.
HUGS:
• Proximity alarms will still sound if tags are too close to doors. Application will still be accessible for admit/discharge. Device Integration Team will be turning off all location based alarms during this time to prevent rogue alerts/sirens/etc
__________________________________________________________________________________
R Recommendation
Please use extra caution for HUGS patients during this time and be aware of all exit points for patients. For temp monitoring, please wait until after the upgrade to leverage location services for devices. For staff duress, please leverage physical panic alarms as primary, if available.
