WLC 4402 w/ corrupt software

Hi all,
I've received a WLC4402 that is missing its primary and backup images. I've so far not been able to find the recovery procedure for this, below is the output i've received. Is there anyone out there who've had the same thing or know of the correct procedure?
Cheers,
Nick

  • Wlc 4402 errors when trying to join ap

    Hello,
    I have a wlc 4402 controller with software version 6.0.199.4
    now i have problems adding 1131 aps to my controller.
    in the pas i added 15 access points (withouts problems) but
    now doesn't seems to work anymore.
    here's what i got from controller when trying to join
    *Nov 11 12:24:37.739: %LWAPP-3-RADIUS_ERR: spam_radius.c:138 Could not send join reply, AP authorization failed; AP:00:13:c4:93:c1:58
    here's what i got on the AP (console cable on my pc when booting)
    %LWAPP-3-CLIENTERRORLOG: LWAPP Crypto Init (SSC): no certs in the SSC Private File
    Got an idea on this ?
    thanks for help

    Was the AP in automatic mode before? Did you copy the LWAPP recovery image to the AP using tftp?
    All APs manufactured before 2005 or 2006 do not have MIC (manfacture install MIC) installed. You need to use LWAPP conversion tool to convert the AP to LWAPP/CAPWAP; so that the conversion tool will install SSC (Self Signed Certificates) to build the encrypt the LWAPP/CAPWAP control traffic:
    http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html
    As LWAPP discovery image is already there, you need to convert the AP back to autonomous mode and use LWAPP conversion tool to conver the AP:
    http://www.cisco.com/en/US/docs/wireless/access_point/12.3_8_JA/configuration/guide/s38trb.html#wp1058472
    I hope that the mode button is not disable on the AP. if it does, I hope that the break key is not disable. If both the mode button and break key are disable, you need to RMA the AP.

  • WLC 4402 update softwar

    hello everybody,
    actually i'm confused so i want to upgrade my WLC 4402 from 6.0.199.4 to last version available and i have my AP 1242G with version 12.4(21a)JHB1 I just want to know what's the version compatibility beween my WLC and AP,thank you for your helps 

    Hi,
    Go for 7.0.250.0(It is the last supoort version for this WLC). You can directly upgarde from 6.0.199.0 to 7.0.250.0.
    http://software.cisco.com/download/release.html?mdfid=279911193&flowid=7586&softwareid=280926587&release=7.0.250.0&relind=AVAILABLE&rellifecycle=ED&reltype=latest
    And 1242 AP supported this software.

    Hi All,
    appreciate your support for a problem i started facing today. i have a Cisco WLC 4402 running version 7.0.116.0 and it is working great with 25 Cisco 1252 APs. we have recieved a new 20 Cisco 1041N APs today and i installed one in our site but it doesn't work. it worked fine and loaded the image from flash and got the WLC ip address through DHCP option and started showing the below error:

    i searched for the regulatory domains difference between  AIR-LAP1041N-E-K9 and  AIR-LAP1041N-A-K9 and didn't find any difference that may affect the operation of this AP.
    just to mention that our configuration in WLC for regulatory domains is:
    Configured Country Code(s) AR 
    Regulatory Domain  802.11a:  -A
                                 802.11bg: -A
    My question is, should i only include my country in the WLC (IQ) to add the requlatry domain (-E) to solve this problem? or changing the country will affect the operation of all working APs??
    Appreciate your kind support,
    Wisam Q.

    Hi Ramon,
    thank you for the reply but as shown in the below link:
    http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn7.0.html#wp233793
    the WLC in version 7.0.116.0 supports Cisco 1040 seiries APs.
    Thanks,

  • WLC 4402 username and password expires automatically

    Hi,
    We are facing issue with Cisco WLC 4402 (Cisco AireOS Version 4.2.205.0) and username and password expired automatically. It happens very often. We are not able to retreive the password, so everytime we need to reset(factory default) the Cisco WLC4402 and doing fresh installation.
    Whether it is the hardware issue or software bug.
    Also is there any possibility of recover the username and [password with resetting the cisco wlc4402.
    Kindly suggest on this issue.
    Regards
    S.Manikandan

    Hmmm.. Strange!! are we using any TACACS to manage?? or just the management username and password??
    I guess after 5.2 WLC code or so we have the option of resetting the password without losing the config!!
    Regards
    Surendra

  • Help Needed - complete newbie - WLC 4402

    I am trying to set up a basic wireless network, completely seperate from our internal network, just utlizing the external internet bandwidth. It will mainly be used for meeting rooms and visitors requiring internet access.
    There should be no need for VLans on the Wireless network.
    The External 7204 router is plugged into a 12 port 2950 switch, which has a connection to the external side of our firewall.The ip address of the router is a public address, so if possible I do not want to give the WLC management ip a public address. The WLC will be plugged into the Cisco 2950 switch.
    I am a complete newbie at setting up the Cisco wireless. I imagine it is down to routing - do I have to purchase another router or is the WLC capable of doing simplified routing?
    Any advice would be greatly apprciated.

    Hi dennischolmes,
    Thanks for your reply, i have tried to create an interface on the controller as you suggested. however I get the following error " Error in setting VLAN and port. Cannot have multiple untagged dynamic interface on the same port" was ondering if you could shed any light on that error.
    Trying to setup the Trunk port on the 2950 switch, it won't allow me to set the encapsulation dot1q - is this down to the software version of the switch?

  • Rolling upgrade of WLC 4402 controllers and APs

    In need to upgrade the software on two WLC 4402 controller in a hospital.   Both WLCs have the same config and one is primary (has all APs connected) and the other backup (no APs connected.)  The APs are placed so there is still coverage if one goes down in an area.    My question - is it possible to do a rolling upgrade to have no downtime for the wireless clients?  My plan would be to upgrade the backup WLC then selectively move APs to it.  If I swap the primary and secondary controllers in the high availability tab on each AP, do I need to do a reset (General - Hardware Reset) or will it automatically reboot and connect to the upgraded backup controller?   When I'm done, I'd upgrade the primary controller and now call that backup.   Does this make sense? 

    I've done this same sort of thing on a slightly larger scale about 5 times now at the hospital I work at.  Quick answer is "Yes, it is possible to do a rolling upgrade and have no downtime for wireless clients."
    I've got 5 WLC's, and I use the high availability tab to move all the AP's off one, upgrade it, and move all the AP's from the next WLC over to it, upgrade that one, etc.
    The thing you need to be careful of is your timing and your choice of APs to move.
    It generally takes about a minute to move an AP between WLCs running the same version.  But if there's a version change that makes the AP upgrade, you're looking at about 6 minutes.
    I do them one at a time, and when they show up in the WLC as being up, running and happy for 1 minute, I do the next one.  And so on.  Takes me about 3 days to go through all 5 WLCs and 375 APs.  Not once have I had a user notice the move.
    Also, in order to test, after I do the first upgrade, I move just one area's APs into that WLC for a day and then test the various flavors of gear we have (phones, infusion pumps, laptops, etc.) to confirm that the new version doesn't have any trouble.  Sometimes it does and I work with TAC to get things resolved before I do the whole hospital.

    Hi,
    we have a Wireless LAN Controller WLC 4402, Software Version 4.1.192.22M (Mesh).
    At the moment there are 6 Access Points in one house, one of them is the root AP. The others are only connected via electrical socket.
    AP’s are: AIR-LAP1131AG-E-K9 / Boot Version 12.3.8.0 / IOS Version 12.4(3g)JMC1
    I think the configuration worked fine over a period of 2 years.
    Now the problem is that the number of access points connected to the controller is changing nearly every minute. At times there is only one AP connected to the controller. So it is impossible for the clients to build up a steady connection. They have to log in via the guest user web interface at short intervals or they can’t see the wireless lan.
    First we thought it would be a problem of one or two “defect” access points. But we replaced 4 of the 6 access points and the problem is still there.
    An example, yesterday:
    13:17 o’clock – 2 AP’s
    13:19 o’clock – 4 AP’s
    13:21 o’clock – 5 AP’s
    13:23 o’clock – 4 AP’s
    13:25 o’clock – 5 AP’s
    13:25 o’clock – 4 AP’s
    13:26 o’clock – 5 AP’s
    13:26 o’clock – 6 AP’s
    13:28 o’clock – 4 AP’s
    13:28 o’clock – 2 AP’s
    Eye-catching is the following message of the log, which appears often: “52       Mon May 16 13:21:56 2011        AP 'AP001d.e557.6fd8', MAC: 00:1d:70:01:bc:20 disassociated previously due to AP Reset. Last reboot reason: power loss
    Also eye-catching is the AP up time. The Root AP is up for over 80 days. But all the other access points show an up time of a few minutes until some hours…but not more.
    Does anybody know what the problem could be?? I read some similar threads but no solution.

    Hey,
    last week I tried to upgrade the controller step-by-step.
    Under the software 4.1.192.35M the problem was still there… access points were often disassociated from the controller.
    There were problems with Software 4.2.207.54M too. The access points couldn’t reach the download-status. The log of the access point said that it could not open the tar-file.
    So I went back to 4.1.192.35M. Of course the controller lost some of its configuration. I configured it new with the same settings as before.
    After it the wireless connection seemed to be a little bit more robust. I asked the users to test the connection at the weekend and this is the answer:
    “so we tested the WLAN during the weekend. The situation definitely improved with respect to before. Authetication is much faster and the connection (when active) is sensibly faster.
    However the connection is still very unstable and it is necessary every five-ten minutes to reconnect (especially for intense network traffic like when watching a streaming content or using VOIP applications. Actually switching off and on again the WLAN card (Airport) often a new authentication is not required. However, without doing so the connection would not resume alone to a working state.
    So what to say? Better than before (thanks) but far from being fixed. From last September to January we did not experience any problem, so it must be something that chronologically happened at the beginning of the year, it is not a systemic problem.
    But there were no changes or anything else at the beginning of the year.
    Do you mean it makes sense to resume upgrading? I’m a little bit afraid of more problems like under 4.2.207.54M

  • Howto find firmware for WLC 4402

    We just bought out first piece of Cisco equipment, an AIR-WLC4402-25-K9 (a WLAN controller). Now I?m looking to find if I have the latest firmware (or whatever it?s called on Cisco) on it.
    I have registered for an account on cisco.com (as you see) and when I go in to techsupport and check the download section for software for WLC 4402 I can?t find anything. Is this because there is nothing to download or is it because I need to register my products serial number on my account some where ?

    Hello Daniel
    What is the software u have running now.. I can see the latest software for WLC 4400 as 4.0.206.0 on the download page...
    With a normal cisco.com account, u will not have access to download softwares/TAC etc.. you need to have special permissions for that.. to download IOS, u can either contact your cisco partner, who supplied you the box or ask them to make a PICA ID for you.. PICA is a special partner Initiated access ID, which can enable features like IOS downloads for specific product which u have procured. You can talk to your Integrator to get this acccess..
    Hope this helps.. all the best.. rate replies if found useful..

  • How to delete a corrupt software from your N81 8GB

    Hello all.
    I'm new to this and i was just wondering if anyone could help me.
    I need to delete or remove a corrupt software on my N81 8GB.
    The problem is that nothing is working and i don't want to format my mass memory.
    Though if formatting is my only resort how can i back up my mass memory and keep my data safe?
    Any other way to remove it?
    Anything is appreciated
    Thanks in advance

    Download Nokia PCSuite 7.1.18.0 and Nokia Software Updater 1.4.85 from Nokia site, then install NPCS first. Connect phone. Then NSU. After that make a memory backup, first on your memory card, next by Content copier from NPCS. After this Open NSU and follow commands.
    But after backup memory you can try to soft reset by dialing *#7370# this reformat your phone and restor software as from factory, but with latest software, if you updated.

  • WLC-4402+AIR-LAP1142N problem

    Hello all,
    I've got a following problem with bringing up simple wireless configuration. There is a WLC-4402 controller and several remote locations (I am testing one so far). Two WLAN configured (one for employee and the other for guest access - no mobility anchoring used, guest is just mapper to VLAN restricted on the firewall). WLC serves DHCP pools for wireless clients. Problem I am experiencing at the moment is that user with laptop is able to connect to guest WLAN, got an IP but can communicate (ping) only its own IP, the controller IP in guest subnet and default gateway (which is the firewall interface). Traffic to any other destinations never hit gateway (I am running tcpdump on it to confirm). I double checked controller config but no luck so far. Could that be caused by missconfigured tunnel? No ACL or restriction set on WLC - see attached config.
    Thank you in advance,
    Peter

    Is this an open network or have you enabled layer 3 security? Web Auth? I can see you have created a lobby admin account so expect that you use this for guest account creation with web auth..
    When you associate/receieve IP address to the open guest network have you then opened a web browser and authenticated? Until you enter your login details created on the WLC I would imagine that you wouldn't be able to send any data.
    If you have authenticated already, can you check on the WLC that the client is associated/authenticated and is the Corp network ok? Also what is the topology between the WLC/Firewall/Remote sites.
    Cheers
    Mat

  • WLC 4402 + 4 1130AP's.

    Has anyone setup a WLC 4402 and few 1130AP's on their network? Here's the scenario we have VLAN's setup on our network. We want to be able an employee can connect to the internal network and public connect to a DSL Internet. I got the internal employee access the internal network but I couldn't get the DSL users connect to the Internet. Internal network uses DHCP server and DSL users uses Linksys DHCP server. Can someone point me to the right setup/config on 1130AP's to connect to DSL using WLC 4402?

    Make sure you can get the VLAN to the internet before you setup the WLAN. 1st off I would test the VLAN that you have setup to go to DSL on a switcport on your core switch and work the DHCP issues out there and then work on the WLAN. can you ping your DSL router intface from your switch. If you can my guess is that the IP helper address is not set right.
    You will then need to point the WLAN to VLAN you setup for the DSL.

  • WLC 4402-50 with ACS 3.3

    Hi,
    We want to use ACS to authenticate an ssh or http connection to a WLC 4403-50 4.2.99 using TACACS+. On our ACS 4.2 test server it works fine. Configured identically on an ACS 3.3 appliance we are not able to log in although we do see a successful login in the Passed Authentications report withing ACS.
    Is there an incompatability between the WLC 4402-50 with ACS 3.3?
    thanks
    Bob

    The Cisco Secure Access Control Server (ACS) provides authentication, authorization, and accounting (AAA) services for users of the wireless network.
    It is also possible to employ a WLC controller strategy that uses an N+1 approach. When using N+1 architecture, each WLC is configured with a WLC that is designated as a backup WLC in the event of a failure. This controller is not used until there is a failure event upon which all APs using the failed controller switch to the backup WLC. This cost-effective approach provides a high level of availability in the event of a single WLC failure scenario.

  • Wireless controller ha between wlc5508 and wlc 4402

    We have 2 wlc:  a wlc 5508 ( license 100 AP ) and  wlc 4402 ( license 12AP).
    We try to setup when 5508 down, 12 identify AP (important AP -Group A) will join 4402 and all other AP (not improtan AP -Group B)
    wont joint  wlc 4402.
    First, all AP join wlc 5508, 2 WLC have same mobility group.
    After that, we  config 12 APs belongto group A have primary and secondary wlc, group B only has primary wlc.
    When wlc 5508 down, some of APs of GroupA and   some of APs of GroupB join wlc 4402. We test many times and we have differnet result each times.
    is theare any way to resolve our problem?
    Thanks.

    Just to add, make sure that the WLC is running the same code, if not, then make sure the ap is supported on the code that is running on the 5508. The issue with mixed code is the ap will upgrade and downgrade very time they switch to a different WLC.
