switch and access points problem

[tibucci]

so I have a router connected to a switch connected to 4 wireless access point, 1 per floor. if i connect on 1 access point it all works, but if i connect to the first, then on the second, then on the third and so on the switch goes crazy. it stop working and the access point don't have internet until i restart the switch.
How do i solve that?
if i goes up and down the stairs a couple time with my phone wifi on the all line goes down. i need to be able to connect and disconnect freely on each floor

sorry for the bad english

How are your SSIDs arranged and what channels are you using. What IPs do the AP have? (Make and model also please)

every access points has a different network name, and i regulated the wifi channel so that they don't disturb each other. the AP are "Access Point N 300Mbps TL-WA801ND" and theirs set each on a different static ip, the first is 192.168.0.100, the second 192.168.0.120, and so on...

You should trouble shoot this problem by putting all the APs in one room with the switch (short cables). Get it to work with 10ft cables, then move the APs to the remote locations.
