On-campus residents brought over 9000 wireless devices that will inevitably interfere with eduroam, and I don't know what our help desk is gonna do about it

I work level 1 tech support for residential halls at a university. We've had the compounding problem of residents bringing increasing amounts of printers and IOT devices on campus over the years that interfere with eduroam signal quality, and this has resulted in us having to go out, check people's rooms, show them how to turn off printer wifi and deactivate any device that projects a wireless network. This is a problem that it mainly handled by our smaller help desk until it has to be escalated. This year's batch of residents just moved in and the total amount of devices ITS reported to us were double that of the previous year, and we were warned that this would greatly degrade eduroam signal quality. For the first time ever, our level 1 help desk was warned by big boy ITS that this would be a problem.

Our lvl 1 help desk has an average of 12-22 part time student workers. We service about 30 residential halls, and most of them have at least 400 residents each. It was hard enough tracking down the hundreds of devices and having them turned off before this year (we didn't even get a fluke until a couple months ago, after the residents were already gone.), and it was a nearly insurmountable problem when we had to deal with it last semester. At this point, this is seemingly an impossible problem and I am wondering if we've just been going about this the wrong way. How do service desks at other universities handling issues like these? I was wondering if it's necessary to place restrictions on residents telling them what they cannot bring on campus, but that's just my first guess, and of course not everyone follows the rules...

Also, campus internet is fine and dandy when residents aren't around. The wireless infrastructure isn't the best, but it works... Except when it can't because there are 9000+ rogue devices in the dorms.

Edit: I'm sorry, I should have stated before that not all of these devices are necessarily connected to eduroam. They're just sitting there, turned on, outputting wireless signals. Printers are a large culprit, but devices like wifi LEDs are sometimes connected to people's laptops so they can change the colors.
