Will running several wireless routers cause any problems?

We are running a Dlink 524 wireless router and we would like to add three more in a school. As far we know, all what has to be done is to plug them in into a LAN wall jack and change their respective IP addresses so they have different network addresses. This will do the job. This should cause no conflicts whatsoever or any sort of problems. Is this correct? Any further input appreciated.

There are several ways to do this...here is one if you purchase all routers.  WAP (wireless access points are preferred), though an actually router provides redunancy.

if the routers are connect via wire to each other... apply the following

- make only 1 router the DHCP server  (if you have more than one, you will have conflict)
- address each unit in the following ip schema

router 1 (DHCP server)
router 2
router 3
router 4

now, the ".1" should be different from what you have already in place in your original network UNLESS you want other to see what's going on your subnet.  Such as administration machines, labs computers, etc.
Security will also be an issue... do you need it? or is it an open network?  You can set up WEP or WPA, however strong you want to make that barrier.

aside from reading the manual...that's it.
Pre N and speedbooster featured routers will interfere with each other because there is not enough available channels in the wifi band.
