DePaul Wireless - Recent Updates

What's New With DePaul Wireless

October 2016

Radius Authentication System Improvements

Information Services administrators have made some additional configuration changes to the Radius Authentication system servers to improve system performance and reduce delays and failures in authenticating client devices.  ​On October 21, administrators updated the Lincoln Park authentication server to address some configuration errors that were problems with the way the server was using server resources.  This change greatly improved the performance of the server and significantly reduced the access failures being reported by the system.  On October 25th, administrators began balancing the processing of authentication requests, so that the load is distributed equally between the two servers instead of serving requests based on campus location.

Radius Authentication System Improvements

Information Services administrators have significantly enhanced the resources of the Radius Authentication system servers to improve system performance and reduce delays in authenticating client devices.  

High Capacity Wireless Access Point Deployments

Information Services engineers have replaced standard access points in various areas on DePaul's campus that regularly have the highest number of wireless users.  In September we deployed high-capacity Aruba 802.11ac access points in the following locations: 
  • First and Second Floors of Lincoln Park Student Center   
  • First and Second Floors of Schmidt Academic Center (SAC)
  • First Floor Lab and Second Floor of CDM Center
  • First Floor Lab and State Street Lobby of Daley Center
  • Seventh through Twelfth and Fourteenth Floors of Lewis Center
  • Eleventh Floor of DePaul Center 
This hardware upgrade should help to alleviate some congestion in these spaces and provide a better wireless experience for students.  

Controller Upgrade

Information Services engineers upgraded the wireless controllers to address some bugs and security vulnerabilities.  

Wireless Network Consolidation

Where possible, we have consolidated the available wireless networks to reduce confusion and overhead (for example, depaulwireless is now only visible within residence halls). 

Website Cleanup

We have cleaned up and consolidated  the structure and details of content related to wireless, to improve usability and reduce confusion.

Summer 2016

Wireless Access Point (WAP) Radio Tuning

Information Services engineers optimized wireless access point radios, attempting to minimize co-channel interference from other nearby access points.  The effect should be an improved signal for client devices, providing more stable connectivity in areas where more than one access point may have been previously accessible by user devices, as well as a better experience when roaming between locations serviced by different access points.  

Enhanced Monitoring

Information Services engineers installed and configured a new wireless network monitoring solution, to enhance visibility of wireless usage and service quality, as well as better troubleshoot wireless problems and user issues.  This additional visibility and monitoring will help optimize the existing WiFi network, and inform plans and proposals for further enhancements and build-outs.

Data Gathering

I​nformation Services conducted a survey of students to gather feedback regarding their wireless experiences at DePaul.  An email was sent to all enrolled students in May, and a brief summary report and full results may be found here.
