Frequently Asked Questions

Common Issues:

  • vuSetup First – If a user has not previously connected to vuNet, they must start at vuSetup.  vuSetup configures the permanent connection to vuNet. 
  • iOS Devices – When setting up a device for the first time, vuSetup may say that it cannot connect multiple times before connecting to vuNet.  This error can also occur when attempting to connect to any other Vanderbilt SSID.  
  • Web Page Start Up – In order to start the setup process using vuSetup, the user must first navigate to any external website such as CNN, Yahoo! or MSN.  Navigating to an external website initiates the redirect process that configures the device for vuNet.

Q - My device will not connect or stay connected.

When troubleshooting erratic behavior of your device connecting with the wireless network, always check with your device manufacturer to make sure you are using the latest software drivers for your wireless card.  Many issues are solved by simply upgrading your drivers to the latest revision.  Do not depend on Windows Update to update Windows wireless drivers.

 

Q - vummiv works better than vuNet.

All of the Enterprise SSIDs (vuNet, vuVoice, vuDevice, vuLegacy) and the legacy vummiv SSID are configured on all wireless APs.  Authentication takes longer to connect to vuNet and gives the impression that vummiv is faster since it does not use authentication.

 

Q - Why do we have to stop using vummiv and use vuNet?  . . . vummiv was so easy to use.

vummiv was easy to use because it offered no security mechanism to restrict access.  Vanderbilt has changed it's security model and is now moving to secure it's vital resources and protect your personal information while on campus.  Although getting setup on vuNet can be somewhat confusing, once your device is properly configured, you will find using vuNet as easy as vummiv plus you will be secure.  To make it easier, Vanderbilt has invested in technology to make the configuration or "onboarding" of your device much simpler.

 

Q - When will 802.11ac be available?

Network Service is evaluating the new 802.11ac specification that will provide data rates up to 6.9Gbps.  In the next couple of months, we plan to begin a 4-year project to install 802.11ac hardware.

 

Q - Will my old 802.11b device be supported?

The legacy 802.11b devices are the number one killer of wireless networks.  Since the newer 802.11g/n have to provide backwards compatible support for 802.11b devices, APs must adjust their speed to the slowest protocol used.  So when an 802.11b user associates to an AP, all the other users drop to the 802.11b data rate; user data rates may change from 300Mbps to 11Mbps.  This will cause major performance issues.  Currently, we only support 802.11b devices in the very limited areas to support legacy patient care wireless devices; it is not widely supported.

 

Q - Will my AppleTV or other Apple devices work on the wireless network?

Yes, Apple Bonjour services with Location Specific Services (LSS) is now available across the university (enterprise-wide) which allows users to browse for Apple wireless services such as AppleTV (AirPlay), AirPrint, and
AirTunes.  You will only see other Apple Bonjour devices that are in your immediate area, so you cannot see devices in other buildings or even even in other areas of your current building.

 

Q - I cannot get my Google Chromecast device to work on the wireless network.

Chromecast devices are not supported on the wireless network.  These devices are designed for personal networks at home and are not suited for large enterprise networks.  AppleTVs are supported.

 

Q - I can't get a good WiFi signal in my office or dorm room.  Can I bring in my personal AP (Linksys, AirPort Express, Netgear, etc.)?

No, these devices can cause major disruption to other users on the wireless network.  If you are having issues with wireless connections, contact the Help Desk and report a problem with your wireless coverage.

 

Q - Is it okay to use my personal MiFi devices while at Vanderbilt?

No, MiFi are devices provided by your cellular phone company so you can connect your WiFi devices to the cellular G3/G4 wireless network as a wireless hotspot.  These devices can cause severe disruption to other users on the Vanderbilt wireless network.  You are also not allowed to turn your phone into a wireless hotspot (PiFi,
Wireless Tether, MyWi, Windows Mobile WifiRouter, etc.) for the same reason. For more information about wireless interference and how to avoid this issue, please visit the VUIT News Blog.
