Enviro Urban can't connect to open wifi network

Hi all, I am attempting to set up my enviro urban. At my university, we have a dedicated iot-network for devices such as sensors or microcontrollers. This network is protected only by a white-list and uses an empty password. My pico cannot connect to this network, even though I have registered it with my university by submitting the MAC Address. After finding this thread I believe the issue is that the wifi network is open, and that this is specific to the raspberry pi pico w. I have tested the connnection on my home internet which has a password and it was able to connect. I admit that I don’t know how to apply the solution listed in the thread. Has anyone else had a similar issue or know a way to fix this?
