Wireless N on 4402
I have a controller 4402 with 19 access points. They are all currently 802.11 g, but I would like to activate 802.11n. I under firmware 22.214.171.124, and in the tab at the top, wireless 802.11b/g/n, under high flow, I checked out 11n Mode and all the boxes to the right. However, it only allows customers to connect to 54 Mbit/s to G. How can I activate N?
First off I'll assume with this version of code, you use 1252 AP since it's 802.11n AP only supported in version 5.1. To get CSM rates make sure that your WLAN active WMM is authorized and your safety is to be wide open with no encryption WPA2 with AES encryption. These are the security modes that both allow CSM rates.

How can I disconnect client PC to help AP Wireless LAN controller 4402? Only, I can disconnect my APs but not the client of the AP.
Thanks in advance.
You're not the only one who is busy! :)
When you choose to "CONTAIN" an AP, client or something, it means that up to 4 of your KNEES, will adopt an approach of Robin and transmit a massive amount to authenticate the package for the poor bastard. Basically, he's got a back and the target will not be able to authenticate on your wireless network until you raise containment. So be sure you want to do this.
The main Web page, Ad - Hoc Snape. You can find the MAC address of your target customer wireless. Click on this. In a new page, you will find a number of drop-down menus. Choose "external", "malicious" and choose the number of APs, and then you choose contains.
\Hope this helps.
We have awireless LAN Controller "Cisco 4402 with software version 126.96.36.199" we use the Access Point 'AIR-LAP1242AG-E' and his works fine, we bought the new APs with the model "AIR-LAP1142N-E-K9" but its not working with our controller and restart continuously. I connected the console and checked the logs from the console that is given below. Please let me know is this controller WLAN is compatible with the APs new or not, or do I need to upgrade the operating system of the LAN Controller and if I upgrade the operating system of the WLAN controller it will support the old APs or not.
Thank you in advance for your response and support.

Upgrading to a new version of the software
Remember messages useful rate. Thank you.
I need help setting up a Cisco 4402 Wireless Controller. I want to have users automatically connect to the wireless network, but not to have access to all the resources network until they open a web browser and provide their domain user name and password or a guest account provided by the receptionist.
I tried many different configurations but can't seem to make it work properly. More time then not when I put on the WIFI network security it causes my wireless network to disappear from the list of wireless avaialbe.
Here's my network configures:
1 - 4402 wireless LAN Controller
2 - Aironet 1130AG antennas
1 - 5510 cisco ASA
1 - 4503 core Router\Switch
Windows domain Server 2003 with RADIUS running on the domain controller.
Thanks in advance for the help.
Glad you got it working...
We have a 4402 WLAN controller with a bunch of AP in 6 locations. The software is installed on a Windows Server 2003 server - since our society must be in accordance with various compliance agencies, we are in the process of getting rid of all 2003 servers in our infrastructure as they will be supported are more early next year.
I created a new server (2012 R2) and tried to install, but get the error that it is only supported on Server 2003 or Red Hat.
Is there a way to get this installed on one different platform other than 2003?
Yes, you can keep the same equipment (WLCs and AP).
I was just saying about upgradation WCS to the CNS / prime infrastructure
NCC/WCS are just a management for wireless LAN controllers APs. so if you change the WCS to the CNS, then it will affect any service.

I have a bunch of 1130AG (35) and 1231 points of access. I just bought a controller 4402 so I could handle these much easier access points. I currently have the offline access points, so I could control. With the wireless in the mix controller, that I have to fix these to light mode or can I leave them offline.
We know not the operating instructions so I can leave them in stand-alone mode. Most of them is in the rafters in our warehuse, and I didn't have to pull of these if I have to. If I can use them offline, how can I do that?
Thanks much for any info!
A WLC manages autonomous APs.
So if you want to centralize the management of your APs through the WLC, you will need to convert it to light and enter them on the WLC.
To convert the lightweight access points, you can choose between several options:
1. thanks to a specific upgrade tool that you could install on a PC:
2. [the most evolutionary] by WCS, with a model of migration that could apply to several APs:
3. [not in any book] by the following steps:
3 (a) download the CEC lwapp recovery image and store it on a TFTP server.
3 (b) Telnet to the stand-alone PA and issuing the following command:
Archive Download-sw / overwrite/reload tftp: / // [lwapp recovery image file path]
As a general recommendation, before to convert the lightweight access points, you can be sure that the wired infrastructure behind is ready to direct them to the WLC for recording.
It's suggestions explained in the link on the above option #1.
Hope this helps,
If this helps you or answers to your question if it you please mark it as 'responded' or write it down, if other users can easily find it.
Is it possible to config only 1 GB to 4402 controller LAN connection. Or should I use two connectors Go?
Because I have only 1 GB free on my switch port.
You can use the port that a single concert for you to connect to the switch. 2 ports can be used if you want por tchannel switch and you want your controller to work with a LAG.
But you can simply connect 1 port switch to the controller and configuring manamenet and interface ap - manager link to a physical port depending on what you are using.

any help or links would be appreciated
Altogether. Just set up a new Interface & WLAN with no encryption L2 & WebAuth L3, then add an account of the Ambassador Hall.
This link should help:
My client has a controller 4402, which seems to be at the origin of a TCP request on the port of 2006.
Their edge router blocks the communication with an acl.
Here are two entries in the router log:
Apr 26 16:30:55: % s-6-IPACCESSLOGP: list of inside denied tcp 192.168.1.5 (2006)-> 126.96.36.199 (64344), 3 sachets
Apr 26 16:32:55: % s-6-IPACCESSLOGP: list refused tcp 192.168.1.5 (2006)-> 188.8.131.52 (42315), 6 packs of college
192.168.1.5 is the management on the controller interface.
The destination is not always the same.
Any thoughts would be helpful.
What is the virtual IP address?
Definitely looks like this bug then it comes in from the IP Address of the service:
CSCsw93671 Packets from the service port sent by wlc when not connected
It has not yet been resolved.
I just received my controller 4402 and a ton of AP for my wireless application. Unfortunately, I have not received the 1000BASE-T SFP to hook the thing up to my network. Anyone has any suggestions for getting this going while I wait for my upcoming part? I'm desperate!
Sad to say until you have the modules SFP is impossible to connect these controllers in the network.
If you have a spare or sitting idle in any switch you can use the same with your controller 4402 plug on the circuit-switched network.

I have WCS and WLC 4402 and want to deploy access points in all the different versions this unique WLC's control. I wish that every building and ap in the building have their own ssid/WLAN.
All buildings are connected through fiber to the main campus switch where the WLC.
I can do it and someone can point me in the right direction?
You can use the override wlan to do this

We have an a 4402 with several wireless networks, including a WLAN of comments. Is it possible to route all traffic from the WIRELESS network invited to a separate ISP? Guest is configured on one VLAN different. Would it configured in the 4402, switches, or our ASA device?
Thanks in advance for your help.
On the controller, I'd send guests to a specific interface, which is a VLAN / subnet specific. Then I route this subnet the second ISP of your router or Layer 3 switch...

Bib Hello and welcome to the forum,
What interface your wireless LAN is mapped to?
The issue of the CLI:
Show wlan summary.
It depends what WLAN on your AP really corresponds.
In addition, what is the DHCP server configured in the guestwlan of the interface?
Run the command:
show inetrface detailed guestwlan
Rating of useful answers is more useful to say "thank you".
I was wondering, how you improve the license on an AIR-WLC4402-25-K9 to manage 50 points of access instead of 25? Is this all just a software upgrade or update license? And how to buy the upgrade software or the license? What is the part number? I could not find anywhere.
You don't like that answer, but the number of AP on a WLC support is based on the hardware configuration and cannot be changed. You will need to buy a second WLC. The advantage is that you will be able to add redundancy to your deployment :) Here's a clip;
\\The limitation on the number of supported access points is based on the hardware you have. The WLC 4402 with two gigabit Ethernet ports is available in configurations that take in charge of 12, 25, and 50 points of access. The WLC 4404 with four gigabit Ethernet ports supports 100 access points.
4400 series WLAN controller up to 12 Cisco access points
4400 series WLAN controller up to 25 Cisco access points
4400 series WLAN controller up to 50 Cisco access points
4400 series WLAN controller up to 100 Cisco access points
I hope this helps!
It is my first upgrade of wlc. I have 2 4402 s with 12 AP1242s lwaps divided between two controllers. What is the best practice in upgrading wireless LAN controllers? Here I have a controller powered off while I upgrade to another or keep both during the upgrade process?
Thanks in advance.
I don't think that it really matters if 1 or both are on the upgrade. Cisco recommends that all radio is disabled before the upgrade... it is an interruption scheduled wireless! I advise you to read this guide for that: -.
