Connecting to utexas-iot Wi-Fi
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:
- Go to https://network.utexas.edu
- Log in with your UT EID (via UTLogin)
- Click the "Register Wireless Device" button
- Enter your device's MAC address and a description, and click the "Register" button. NOTE: if your device randomizes its MAC you may have to configure it not to do so (see device guidelines).
- The portal will provide a key, and you can always go back to the portal if you forget
On your IoT device:
- Select utexas-iot from the available wireless networks
- Enter the WPA2 key provided to you in step 5 above
- NOTE: if your device randomizes its MAC you may have to configure it not to do so (see device guidelines).
- Devices registered before 12/20/2021 were issued unique WPA2 keys for each device. Devices registered on or after 12/20/2021 were issued the same WPA2 key for all devices. To look up the WPA2 key for a given device, you can go to https://network.utexas.edu, select "Wireless Devices", and click under the "Wi-Fi Password" column to unmask your device's key
- To un-register a device, go to https://network.utexas.edu, 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 20 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.
- To protect users of utexas-iot, devices cannot talk directly to each other without going through the NAT/PAT firewall. Some service may expect to be in the same broadcast domain and will not work properly with utexas-iot.
utexas-iot is encrypted over the air with with a key shared between devices you configure. 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), or older devices not compatible with utexas.

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