Do you have this issue at multiple locations on the university's campus?
Do you need to authenticate to their WiFi network?
Does the university require you to provide hardware information about your laptop before it can access their network? Does the university require the use of any anti-virus software or any other software to connect to their network?
Do you have any anti-virus apps, cleaning/optimizer apps, or third party security software installed which may interfere with the normal operation of macOS? These types of apps are not needed on a Mac unless required by a school or employer. These types of apps usually cause more problems than they solve.
Does booting into Safe Mode make any difference? Or using another macOS user account (create a new user, logout of current user, then log into the new user & test)?
If the only WiFi network you have problems with is the university's, then you will need the assistance of the university's networking techs. Sometimes a WiFi access point just needs to be rebooted. There is always a chance the WiFi signal is too weak or there is too much signal noise in the area. The university should try to work with you to figure this out especially if their WiFi network is the only one you are having issues with. I know our organization had issues with some very specific model Chromebooks where we had to configure our WiFi access points a bit differently for them...actually had to create a special SSID for them to use until the issue was resolved by an update to the access points I believe.
FYI, I am not aware of any widespread issues with Apple Silicon Macs and WiFi access points either on these forums or with any of our organizations Apple Silicon Macs. Keep in mind schools & businesses typically have a tightly locked down network especially for guest users bringing their own devices. It would not surprise me if a configuration change is needed, but of course if you are the only Mac user with issues, the university may not be convinced of a problem. Of course macOS 13.x Ventura has introduced some more changes as well, so there is always a possibility that their could be some sort of macOS bug or compatibility issue.
