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, 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.

  • [WLAN controller] Unplug the PC Client in AP

    Hi guys,.

    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.

  • Inconsistent WLAN controller with AP 'AIR-LAP1142N-E-K9.

    Hi all

    We have awireless LAN Controller "Cisco 4402 with software version" 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.

  • Helps to configure a Cisco 4402 wireless controller


    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

    8-2960G switches

    Windows domain Server 2003 with RADIUS running on the domain controller.

    Thanks in advance for the help.

    Glad you got it working...

  • Upgrade of Cisco Wireless Controller 4402

    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?

    Thank you!

    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.

  • 4402 wireless controller and the 1130AG access points

    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!


    Hi Dave,.

    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,

  • LAN 4402 wireless controller

    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.

    Hi René,.

    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.

  • 4402 delivered without SFP 1000BASE-T controller

    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!

    Hi Sean,.

    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.

  • How do you improve a 4402-25-4402-50?


    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.

    Thank you

    Hi, Nolan,.

    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!


  • 4402 wlc move from 4.1.171 to 4.2.130

    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: -.
