Current students, faculty, staff, and official visitors have access to the utexas-iot (Internet of things) wireless network on campus. 

To connect to utexas-iot, your device must support WPA2-PSK (aka. "WPA2 Personal" or "WPA2 Home"), and you must register your device with your UT EID.

From a network-connected device:

  1. Go to
  2. Log in with your UT EID (via UTLogin)
  3. Click the "Register Wireless Device" button
  4. Enter your device's MAC address and a description, and click the "Register" button
  5. Make note of the WPA2 key generated (will be unique for each device you register)

On your IoT device:

  1. Select utexas-iot from the available wireless networks
  2. Enter the WPA2 key provided to you in step 5 above


  • WPA2 keys are unique for each device you register. To look up the WPA2 key for a given device, you can go to, select "Wireless Devices", and click under the "Wi-Fi Password" column to unmask your device's unique key
  • To un-register a device, go to, select "Wireless Devices", and click the "X" for the row corresponding to the device you wish to un-register
  • For assistance locating your device's MAC address, please consult the product documentation for your device, or use search engines for guidance.  Some popular devices are documented at this university site.
  • The keys are 16 numeric digits.  There are no spaces between the digits.  They are shown in groups of four to enhance memorability and readability.  Numeric digits are to aid entry on IOT devices which often lack full keyboards.


utexas-iot is encrypted over the air with an individual key for each device (unlike a typical WPA2-Home network where all devices share keys and can eavesdrop some of the traffic).  In general, utexas should be used if a device will support both WPA2-Enterprise and WPA2-PSK, due to its stronger encryption.  utexas-iot may be indicated for devices that are difficult to configure or access (the keys remain the same even if EID passwords, which would impact WPA2-Enterprise devices).

Applications that require publicly accessible IP addresses:

Due to the large number of devices on the wireless network, connected devices are not assigned publicly accessible IP addresses.
