I've lived in an apartment for the past year that is connected directly to our university network. I have an airport extreme router that I've tried to set up responsibly with no SSID broadcast, WPA2 with extremely difficult password, transmission power set to 25% etc. It has also been set to 'share a public IP address" and everything has so far worked smoothly. Recently, however, all apartments in the complex received letters saying that there had been disruptions on the network and that it was most likely due to wifi routers -- which are NOT permitted. If we temporarily disregard that ban, is it possible that my router is causing any disruption? And, if so, what could I do differently to ensure that it does not? I've tried setting it to bridge mode, but that does not work at all. We are allowed to register 10 mac addresses and I have registered all my devices, but in bridge mode none of them can connect . As I understand it, in bridge mode the university servers are distributing IP addresses to devices that are registered on the network -- is that correct? Then what could be the reason for bridge mode not working if my devices were registered properly? My main question is whether my router could be causing problems with the above setup? Any advice or ideas would be greatly appreciated, but please let's not get into a discussion about whether it's ok to use a wireless router when it's not permitted... Cheers!
