First of all, I'm no network administrator and have not much experience with networking, so if anything is unclear, please say so.
In a dormitory, every room has 1 LAN port. Some people prefer to use a wireless router instead of a LAN cable, but the DHCP server features in these routers are messing up the dormitory's network, distributing IP that people should not get. I'm not sure which type of Switch is in used in my dormitory. I don't have access to that critical area YET, but these switches should be able to take control and not letting other wireless routers to distribute false IP, right? Switches should be able to do that, right?
So I want to ask in advance to get some general basic idea. (I am negotiating with the dormitory owner) What are some of the things should I look for and do in this case?
