Cisco WAP321 crashes entire network

I'm trying to add a Cisco Access Point (WAP321) to our network and every time I plug it into the network, the internet goes down. The Access Point works, but the rest of the network loses internet access. DHCP is disabled and I have manually set an I.P. address and this issue still occurs, so I've ruled out a possible I.P. address conflict. What could be causing this? The network consists of a modem going into a Cisco 5505 Firewall and then to a Cisco switch.

Hi Charlie,Is the network

Hi Charlie,

Is the network still be able to communicate between each other normally except for internet access?, did you try to ping the ap ip address from the firewall and the switch while the problem is occuring?

I am sorry to hear that you are experiencing this issue. 

What IP scheme are you using on your network? Are you pre-configuring anything else on the the AP before you add it to the network? Can you try to by-pass the switch to see if you get a different result?

If this does not improve your issue, please call our support center and open a case so that one of our engineers can work directly with you.
