This requires a PC tool, which will generate certificates, and create a hash file, necessary to get the IOS AP into the LWAPP mode and recognized by the controller. I've attached the guide, which provides the steps to convert, or re-vert an IOS AP to LWAPP,
and will be happy to answer your questions or provide any other assistance you need. It is best, if your AP is in the same VLAN
subnet as the controller, and you will need a DHCP server on this network, to provide an IP address to the APs because this is Layer3. We can manage IOS APs on the c2006 and c440x platforms of WLC. Section 6 of this guide describes DNS and DHCP option 43 methods of feeding your WLC's Management Interface address to the APs.

  • IOS to LWAPP for 1130AG Access Points

    We have initially installed IOS-based 1130 APs. If we would be upgrading it to LWAPP mode, could we pushed IOS-to-LWAPP upgrade thru the network? what procedures are required?

    Hi Leopoldo,
    This is possible and fully supported and can be done using the "LWAPP Upgrade Tool". Have a look at the following;
    LWAPP Upgrade Tool Troubleshoot Tips
    http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008072d9a1.shtml
    Access points must run Cisco IOS Release 12.3(7)JA or later before you use the upgrade tool.
    System Requirements
    You can use the Autonomous to Lightweight Mode upgrade tool to install Cisco IOS Release 12.3(11)JX on these access points:
    All 1100 series access points containing MP21G (802.11g) radios
    ***All 1130, 1230, and 1240 series access points
    All modular 1200 series access points running Cisco IOS software and containing these supported radios:
    802.11g: MP21G, MP31G
    802.11a: AIR-RM21A-x-K9, AIR-RM22A-x-K9
    All 1300 series access points in access point mode
    http://www.cisco.com/en/US/docs/wireless/access_point/ios/release/notes/b311jx1.html
    Cisco has released a free tool called the "Autonomous to Lightweight Mode Upgrade Tool" that allows selected Cisco Aironet autonomous access point models to be configured for lightweight mode operation.
    The Autonomous to Lightweight Mode Upgrade Tool supports the following models:
    Cisco Aironet 1240AG Series access points
    Cisco Aironet 1230AG Series access points
    Cisco Aironet 1200 Series access points that contain 802.11g (AIR-MP21G-x-K9) and/or second-generation 802.11a radios (AIR-RM21A-x-K9 or AIR-RM22A-x-K9)
    Cisco Aironet 1130AG Series access points
    **Cisco Aironet 1100 Series Access Points that contain 802.11g radios (AIR-AP1121G-x-K9)
    Cisco Aironet 1300 Series Access Points/Bridges (AIR-BR1310G-x-K9 or AIR-BR1310G-x-K9-R). A Cisco Aironet 1300 Series operating in Lightweight Access Point Protocol (LWAPP) mode only operates as an access point. This series does not support LWAPP bridging mode.
    The Autonomous to Lightweight Mode Upgrade Tool supports a process to migrate an autonomous access point from autonomous mode to lightweight mode. Unlike a VxWorks to Cisco IOS Software upgrade, this process is a Cisco IOS Software upgrade to the existing Cisco IOS Software image-not an operating system "swapout". In converted access points operating in lightweight mode, Cisco IOS Software continues to run on the access point, while LWAPP is used to communicate with a wireless LAN controller. Since LWAPP supports automatic access point configuration, there is no need to retain or convert the original autonomous Cisco IOS Software access point configuration.

  • AP-to-LWAPP-Upgrade-Tool won't install

    I have downloaded 3 versions, 3.0, 3.2 and 3.4.... all of them hang after extracting the files and launching setup.exe....
    I have tried on several different Win XP machines... same result
    Don't know if it matters at this point, but the intended WAP is an AIR-AP1252G-A-K9...
    any ideas?

    You can't use the tool for that:
    Here is direction from a member on this forum:
    It took me a while to get this information, so thought I'd share. Here it is:
    You cannot use the upgrade tool to do the IOS to LWAPP for the 1250 APs.
    Here is a method to do the conversion.
    *Method 1 : ( Mode Button )*
    1. Install an external TFTP tool such as tftpd32 tool from http://tftpd32.jounin.net/
    2. Assign IP address in the range 10.0.0.2 - .254 ( Ex : 10.0.0.3) to the tftp server (your laptop or pc).
    3. Download the IOS to lwapp image onto the tftp's root directory. Use http://www.cisco.com or
    http://tools.cisco.com/support/downloads/go/IPCheck.x?defAdv=N&sftAdv=N&image=c1250-rcvk9w8-tar.124-10b.JA3&filepath=/swc/esd/02/crypto/3DES/281235915/guest&filename=c1250-rcvk9w8-tar.124-10b.JA3&advUrl=null&isk=Y&defInd=N&mdfid=281235915&sftType=Autonomous%20To%20Lightweight%20Mode%20Upgrade%20Image&optPlat=&relVer=12.4(10b)JA3&fileId=271159&treeMdfId=278875243&treeName=Wireless
    4. Rename c1250-rcvk9w8-tar.124-10b.JA3 to c1250-rcvk9w8-tar.default
    5. Make sure you set the IP address on the BVI interface of the AP if not set. Set it in the 10.0.0.x range. Default is 10.0.0.1.
    6. Connect the Ethernet port on AP to your TFTP Server ( Laptop )
    7. Hold the mode button and power off the AP.
    8. Power back the AP while continually holding the mode button for 20-30
    seconds.
    *Method 2 : ( Archive Command )*
    1. Install an external TFTP tool such as tftpd32 tool from http://tftpd32.jounin.net/
    2. Assign IP address in the range 10.0.0.2 - .254 ( Ex : 10.0.0.3) to the tftp server (your laptop or pc).
    3. Download the IOS to lwapp image onto the tftp's root directory. Use http://www.cisco.com or
    http://tools.cisco.com/support/downloads/go/IPCheck.x?defAdv=N&sftAdv=N&image=c1250-rcvk9w8-tar.124-10b.JA3&filepath=/swc/esd/02/crypto/3DES/281235915/guest&filename=c1250-rcvk9w8-tar.124-10b.JA3&advUrl=null&isk=Y&defInd=N&mdfid=281235915&sftType=Autonomous%20To%20Lightweight%20Mode%20Upgrade%20Image&optPlat=&relVer=12.4(10b)JA3&fileId=271159&treeMdfId=278875243&treeName=Wireless
    4. Make sure you set the IP address on the BVI interface of the AP if not set. Set it in the 10.0.0.x range. Default is 10.0.0.1.
    5. Connect the Ethernet port on AP to your TFTP Server ( Laptop )
    6. On AP, type archive download-sw /overwrite /force-reload tftp:///c1250-rcvk9w8-tar.124-10b.JA3
    Going the other way (lwapp to autonomous)
    http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html#wp161272
    If you need to manually "prime" the LWAPP:
    AP#lwapp ap ip address
    AP#lwapp ap ip default-gateway
    AP#lwapp ap controller ip address
    AP#lwapp ap hostname
    (optional)
    Hope someone finds this useful!

  • "Logging LWAPP message to 255.255.255.255" after LWAPP Upgrade

    Hello,
    I have a WLC 4402 with the AP-Manager IP 192.168.253.34. This WLC is in the version 5.0.148.
    I have an AP-1130 with IOS. I upgrade this AP with IOS to LWAPP AP. Just after this upgrade, i see this AP in a state "Download" in the WLC Management page. But after the download, this AP was disassociated.
    When i try to restart the AP, i have this log :
    Translating "CISCO-LWAPP-CONTROLLER.*****.**"...domain server (*.*.*.*) [OK]
    *Mar 1 00:00:31.383: %LWAPP-3-CLIENTEVENTLOG: Performing DNS resolution for CISCO-LWAPP-CONTROLLER.******.**

    I don't understand why i have this log "Logging LWAPP message to 255.255.255.255" after the LWAPP Discover state.
    Thanks
    Paulo

    this is an enhancement for APs to log messages (to help troubleshoot join issues) to a syslog server. If one's not configured, it'd send out a broadcast. Here's more details on this:

  • I am experiencing wireless connection problem on 4s after ios 8.1 upgrade. The wireless icon appears showing that it's connected but webpages do not load. I have checked my internet connection with other devices and seems to be alright. what to do?

    Hi
    I am experiencing wireless connection problem on 4s after ios 8.1 upgrade. The wireless icon appears showing that it's connected but webpages do not load. I have checked my internet connection with other devices and seems to be alright. what to do?
    I have tried reseting the network settings and forgetting my wireless connection and re-connecting to it. I even backed up my phone on itunes and restored it, factory reseted it. Nothing seems to work.
    Also after my upgrade to ios 8.1 my personal hotspot option under cellular data has disappeared.
    Would you please help me out? I would really appreciate it.

    Hi..
    Restart your router then restart the iPhone to test.
    If that doesn't help, try this support article >   iOS: Troubleshooting Wi-Fi networks and connections

  • Ipad 4 retina display is slow after iOS 8, also upgrade the the iOS 8.0.1 i think and safari is slow, animations are slow, and i can't restore it to iOS 7, there it was great.

    ipad 4 retina display is slow after iOS 8, also upgrade to iOS 8.0.1 i think and safari is slow, animations are slow, and i can't restore it to iOS 7, there it was great. i mean its like my iphone 4 with iOS 7 in its best days. i hope no to get stuck again, i mean please let me go to the iOS 7)).

    Upgraded my ipad4 from ios6 to iOS 8 because the new WSJ app required it. HUGE MISTAKE!!!!!!! I can maybe understand some apps being slower but not Safari or Chrome. Apple must be throttling back the ipad4 processor even more with ios8 to force an upgrade to the next gen iPad whenever it arrives.

  • Sound problems after iOS 4.2 upgrade

    Experiencing very poor sound quality after iOS 4.2 upgrade. Bad eq, left channel dropping out, sounds like heavy reverb. Exists with iPod and pandora apps. Tried adjusting eq in settings. Any one else having problems?

    Yep I just upgraded to new OS 4.2 on iPhone 4 and I get this static buzz sound when talking to people it's really annoying and sound quality is terrible. What happened? I went back to the shop and they said it's the upgrade and that there is an issue with it. They also said there is no point leaving the phone with them as they can't fix it that it's upto apple to release a patch for the problem. Can we get a fix for this soon before I damage my ears?

  • Dictation problems after ios 8.2 upgrade

    I rely heavily upon dictation.   2 problems occur (at minimum) after ios 8.2 upgrade to iphone 6. .
    1. I wasnt going to add this dictation bug (feature ;-)) b/c couldnt reproduce the seemingly safari bug when got home, but as I was dictating my first sentence for defect here, it happens in this text box on any line. :-(.
        1. Problem is as soon as dictation types in word Or words, when I hit done, it erases what was just dictated!  Happens on even just ine word. (So having to manually type all of this n I stink at typing ie, time consuming).
        2. I can paste characters from noteoad into here...so must be dictation relateD...it seems.
    2.  In the calendar textbox, when I dictate a new event (doesnt happen in location textbox) and the last character before it fills up the end of textbox (just before the "x"), it automatically does "done" for me (the beep sounds), it stops dictating, but more annoying is it will no longer allow me to continue dictating in that new event's top textbox.  That means I HAVE to type n I stink at that. To reproduce I simply:
    1. press the microphone.
      2. Type in only numerics 1 thru 17....it will dictate to look like this:  123 456-789-1011 1213 1415 1617
      3. "Beep/dong" noise because it hits the end of characters alowed it seems n decides it is "Done".
      4.  press the microphone
       5. "Beep/dong" noise because it wont let you dictate any more of anything said.
    I Couldnt find the entry where google shows someone with what looks like same issue/bug/defect/feature # 2, so entering this.
    I Have warranty but cant figure out how to get phone support for iphone (only mac ...last year).
    I don't seem to have this problem using i notepad in phone when he gets to having to wrap. :-)
    I Have not trieddictation on my mac...yet.
    CAn someone help on these issues please? Thanks!

    Hey Markwoody,
    Wow! That definitely sounds frustrating, but good job so far isolating and troubleshooting the issue. We have a few more steps that we can try in an attempt to resolve this issue:
    First, it sounds like you have tried restarting your phone. Let’s try a reset instead:
    Restart or reset your iPhone, iPad, or iPod touch - Apple Support
    https://support.apple.com/en-us/ht201559
    How to reset
    - You should reset your device as a last resort and only if you can't restart it.
    - To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
    If the issue persists, we’ll want to restore your device to factory settings and test once more. You can backup your device, but be sure to restore it as new first for isolation purposes, as restoring a backup can sometimes restore the same issues that you were experiencing before.
    Use iTunes to restore your iOS device to factory settings - Apple Support

  • Since iOS 8.3 upgrade school iPads need to reset very often

    Since iOS 8.3 upgrade school iPads need to reset (holding down home and power button) very often as they do not turn on. iPads are charged at the time.
    Anyone know how to fix this? It is making life at the school quite difficult.

    I take that back, music is messed up too!  Some of the "default" playlists, such as "recently added" , "Recently played" and "Top 25 Most Played" are listed on iTunes and were always on my phone... but since iOS 8.3... they are gone... Still in iTunes, but not on device.

  • IPad ios 4.2 upgrade debacle

    I was on the phone this morning with a level 1 Apple Care tech, who basically told me that my sudden lack of all internet connectivity is caused by problems with my router/firewalls, and has nothing to do with the ios 4.2 upgrade.
    This is my first Mac purchase and I am not familiar with how quickly Apple puts out patches. Do any of you experienced Mac users have some sense of timeframe? Are we talking a week or two or next April (as someone on another thread in this forum mentioned.)
    <Edited by Host>

    An iPad bought a few days ago connected fine to a Linksys (Cisco) router, then yesterday refused to negotiate a valid IP address via DHCP handshake. No amount of resetting, restarting, or rebooting--even restoring--either the router, cable modem, or iPad resulted in success. (This included forgetting networks and renewing leases.) All other devices in the network connected and re-connected flawlessly; conversely, the iPad would connect to other wi-fi networks.
    The router was put through several changes, including choosing only 11g devices, and changing transmission channels & SSID names. Finally, what worked a mere seconds ago, was changing the security protocol from WPA2/AES+TKIP to WPA/TKIP (only). That kickstarted the iPad into a valid IP address. In a fit of impulsivity, I changed the security BACK to WPA2/AES+TKIP and then to AES (only), and the iPad continues to connect appropriately, even after awakening from sleep mode.
    I'm not sure what happened, but my guess is that the IP lease expired, and the iPad refused to negotiate a new address with the router, until the security change forced something loose. In any case, this seems to be a prevalent issue, judging from the number and breadth of threads clamoring about this issue in many forms, so this just a note of what worked for me. (I posted this in the discussions, as well.) Ciao.

  • IMessage not working after iOS 5.1 upgrade! Feedback pls

    iMessage not working after iOS 5.1 upgrade, anybody experiencing this as well? Feedback please......

    You shouldn't have to hard restart and it shouldn't have anything to do with your router.  If anyone else runs into this problem try resetting the network settings on your phone.  All the steps to do this can be found here http://tekshot5.com/ios-5-1-imessage-fix/
    Edit: Some of us don't have the option of resetting our DNS servers.  I run my own for example for caching purposes.

  • Unable to install IOS 4.3 Upgrade to new IPAD2/32G/3G

    Hello,
    I just purchased a new IPAD2/32G with 3G Verizon support. I attempted to upgrade my new IPAD2 with the new IOS 4.3 upgrade when prompted by ITUNES.
    I received a message when it the process was done that the upgrade failed. My wireless is working correctly. What can I do to install the upgrade?

  • Since upgrading to 6.01 iOS the app upgrades are locked up and will not download

    Since upgrading to 6.01 iOS the app upgrades are locked up and will not download.

    My wife's phone had similar symptoms, at least with the text notification alert not working.  I have narrowed it down to happening after we use the new navigation feature in the Maps.  When we power the phone off and back on, the alert sound seems to return.  I haven't tried just "killing" the Maps app after we use it...perhaps that would work as well.

  • LWAPP upgrade tool and Windows 7 (64 bit)

    I know this tool does not have a version for windows 7 but the company foisted the OS off on me to "Test" It works fine with windows 7 32 bit but I have windows 7 64 bit.
    So, I was attempting to install and use the autonomous to LWAPP tool to upgrade an 1131 AP to LWAPP. I DL'ed version 3.4 which is the most current I could find. unfortunately, it gives me an error installing saying it could not read from the IPUT file and after installation it is convinced I already have a TFTP server running, which I do not. In addition to all that, when attempting to Uninstall the tool it says _SETUP.DLL is missing.
    With that information in hand I found the _SETUP.DLL on another machine I use and copied it over which resulted in no improvements of note. I did register the dll as well. Any ideas?

    I assume you are using the RTM (Release To Manufacturing) version. I would suggest, if possible, you might want to use the new XP Virtual PC feature (run XP on Windows 7), if the version of Windows 7 you are running supports it. I think the VM runs XP SP3 32-bit.
    http://www.microsoft.com/windows/virtual-pc/download.aspx
    You could also try changing the advance properties of the executable and indicate that it should be run in "compatability mode" of Windows XP 32-bit (I think that's an option, but my Windows 7 computer is at home)
    Whatever route you take, you will receive no support from Cisco in this configuration. If you can avoid it, it might be better to not do LWAPP upgrades with Windows 7 until something official comes out.
    petenugent - please be aware that Windows 7 was released to many people on August 6th. The general public release (of the exact same media) is due on October 22.
