Mac diagnostics won’t run, no internet connection

Hey I recently dropped my computer in its case so I just wanted to check to see if there was any internal damage by running a diagnostics test. I followed all the instructions for Mac silicon but as soon as I try the test it can’t connect to WiFi. The wifi is fine and is pretty quick, but for some reason it forgets the network while in diagnostic mode so I have to re-enter the password every time, and even then it says there isn’t connection even though it shows that it’s connected at the upper right hand corner. I even added an Ethernet connection and restarted the whole operation, but nothing seems to be working and I can’t run my diagnostics test. (Also this is only in diagnostics mode, when signed in the WiFi connects) (and also Also, I can’t do much about the actual WiFi (aka resetting the router) because I’m in a dorm and the WiFi is building wide and inaccessible to me)
