Configure Cisco WLAN contoller and Access point

I am having some problem getting these tow units configured and would like to get some assistance on how to get this done properly. I have configured the Contoller to use our network and to obtain IP's through our DHCP server which seems to be working correctly however when I connect the AP to the contoller it gives it an IP but shortly afterwards it disconnects and goes through the startup again. When the AP does have an IP I try to access through IE but it never connects and eventually disconnects. I configured the RADIUS server on the controller however I don't think I have one so I deleted the entry. In the end I really don't know where to start with this and have numourus PDF documents detailing how to configure but some of the command lines don't work so I can't even configure through telnet.

Hi,

I guess I can help you with this.  Basically first make sure you have wlan controller properly connected to your lan,  Setup a trunk figure out which vlans are going to be for managment and which for ssid traffic.   Only after that you can setup APs, I assume APs are lwap

I have the controller properly connected to my LAN, i assume, because I can access through IE and can log on to the UI but that is about it. I have connected the AP to the controller and it can see the AP for a little bit then the Status light goes Blue, the Radio blinks red and the Ethernet becomes green and at the same time the Radio become green then goes in to a blinking session where the status light blinks purple then green and the radio blinks amber and the Ethernet blinks green. After that cycle it goes back the beginning blinking Blue on status red on radio then both green on radio and Ethernet.

I have set up the contoller to use one IP as the Interface IP and one for the AP interface IP. Is the RADIUS setting needed?

OK, I have made some progress but still not working like it should. I plugged the AP into our network and not directly to the Controller which brought up the unit and I can see it on the controller and my wireless device can see it however I cannot connect to it. The device keeps asking for a user name and password but don't know what that is. I have tried all the passwords I configured for the Controller and still no use. I have also tried my domain name and password and that does not work.

Do I need a RADIUS server? Can I configure my Windows 2003 R2 server to be a RADIUS server?
Yo do not need radius.

APs do not plug in to the controller plug directly in to the network.  Controller ports are for connective to lan
So did it work?

You need to configure the WLAN to use whichever security method you want to employ.  By default the WLAN you configure during the initial setup process will use WPA/802.1x.  You can change this by going to the WLAN tab on the controller, then click on the SSID you want to edit, click on the Security tab and edit as appropriate.

A RADIUS server is not a necessity if you just want to use a pre-shared key.

Ok, I have reconfigured the Controller and I am able to access the console and disabled RADIUS but when I try to connect to the AP it keeps asking for a User Name and Password. I have entered all user names and passwords into that field and still it wont connect. What am I doing wrong?

Nevermind I was able to get this to work after changing the way it authenticates. I do have one more question. The antenna's that are on the AP have one site that is 2.4GHz and the other side is 5GHz, are both on? Which one should I use?

Generally, use both.  You can set this in the WLAN tab on the controller per SSID.
Well you should use both if you going to support A/g/N standard.
