2702-UX-K9 Access Point will not associate with controller.

Hi,
I recently purchased nine new 2702 APs.  Two of them will not associate with the controller.  I realized they they had a different part number.  They ended with UX-K9 instead of -K9 like the others.  It turns out that these are new AP that are universal for any country.  They APs find the controller but need some sort of password to pull the config down.  I"m not sure what this could be? 
From console of AP @ boot....

Rasika,
I have the same issue on my home 2504 with these 2700 UX, I have tried code 8.0.100.0, 8.0.110.0 (Docs say this is the min version supported), and even 8.0.115.0 (latest available) still no dice. The AP won't register, and gives the error stated above. I am seeing 2 images available for the AP, the AP shipped with the later image but  I AP recovery isn't working because it say's unable to find image with XX in the name? I see the TFTP logs, and name the file accordingly no dice, then the unable to find file name -XX pops up too. As you know I am busy during the day this week, but let's jump on a skype and take a look later maybe you have seen something I haven't?
For good measure, also attempted to join a 3650 here at the house IOS-XE 3.6 no dice, going to try 3.7 too tomorrow, It worked for the 3700 UX AP's we had??

  • 3502 access point will not connect to 4400 Series WLAN controller

    I recently upgraded our controllers to the latest version 7 software, as I read this was one of the requirements to get them to connect.  But I am not having any luck getting into a controller.  Normally I plug them in to the network, they pop into the controller listed as something like AP5057.a844.xxxx and then I can finish configuring them, but a static IP on them, etc...
    This is the first of this model AP I have tried to deploy, so I am wondering what is different with these. or what I might be missing in the default config in the WLAN controllers.
    Niether of which are set to "Master" either.
    Thanks in advance, Tandrist

    Hi,
    The 3500 as you mention are supported on code 7.0
    To get the access point to join the WLC we have different options.
    If the access points will be on the same subnet as the WLC then you just need to get the APs to get a valid IP address from the DHCP server and once they have an IP address they will join the WLC because they are on the same subnet as the WLC.
    If the access points are on a different subnet then the WLC you will need to have a DHCP server configured to give the unit an IP address and use option 43 or DNS so that the APs can send the join request to the correct WLC on a different subnet.
    Or if not configure the AP via the console port with the static IP address and WLC IP address.
    Also make sure that you have the correct country code enable on the WLC, and that the APs you purchased are the ones to work in this country, because if not the AP will not join the WLC.

  • E2500 as an additional access point will not connect

    Hello,
    I have AT&T Uverse which provides Internet for my home.  The wireless capability of this router is pretty bad, I don't get good/reliable wireless reception upstairs in my office.  The solution was to buy a Cisco E2500 and add it as an access point upstairs.
    I have the E2500 LAN port connected to the LAN port of my uverse router downstairs.  DHCP is turned off on the E2500.  I have my office PC wired into the E2500.  The home PC works fine, its getting DHCP from the uverse router downstairs and connects and good speeds.  The problem comes with my wireless devices trying to connect to the E2500. 
    I should mention that yesterday when i bought this, all worked fine.  This morning when I came into my office none of the wireless devices would connect to the E2500 at all.   But as soon as I remove the cable that connects the E2500 to the uverse router downstairs they will connect via wireless but of course not get an IP address since that is disabled.  No idea what is going on here.
    I have factory reset the E2500 and uverse router several times and am getting no where.   Any ideas what could be causing the wireless devices to not connect at all?

    I think you are having problems because you didn't give the E2500 an appropriate static IP address outside of your Uverse gateway's DHCP range.
    A better option would be to reset the E2500 to factory defaults and then follow these bridge mode intructions:
    http://www6.nohold.net/Cisco2/GetArticle.aspx?docid=28cee6a2fb0d4176a2210942d1d5836c_Setting_up_the_...
    You should give the E2500 seperate (different names) SSID's and make sure your wireless channels are different on AT&T gateway and E2500.  Use 1, 6, or 11
    The best option, however, would be to reset the E2500 to factory defaults and use the IP passthrough feature on your AT&T gateway.  If you use the IP passthrough feature on the  AT&T gateway, you would use internet connection type DHCP on the E2500 and it would be functioning as a NAT router.  The IP passthrough feature on you AT&T gateway allows your E2500 to receive a public IP address and you will be able to avoid the AT&T gateway's NAT.  So you will just be using the E2500's NAT.  You will need to change the MTU to manual and you can ask AT&T what the appropriate mtu is for Uverse.

  • My iPad will not associate with iTunes, I reinstall and still get prompted to open iPad in Word, Camera or Scanner

    Do i need to change my windows file association?  What is the extension?

    Have you selected the content to sync to your iPad in your sync settings in iTunes. The content that you want to transfer must be selected (checked or "ticked") to sync out will not transfer when you sync.
    For instance - if you want to sync music....
    Connect the iPad to the computer and launch iTunes.
    Click on the iPad name on the left side under devices.
    Click on the Music Tab on the right.
    Click on the albums or playlists that you want to sync - or the entire library if you like.
    Click on the Sync Music Heading.
    Click on Apply in the lower right corner of iTunes
    This applies to all content that you want to transfer from iTunes to your iPad. Make the selections in the appropriate tabs in the iTunes window on the right.

  • Itunes will not associate with my music folders on an external hard drive

    I moved all of my music on both libraries for two separate Ipods onto an external hard drive. Now when I open Itunes neither one of the libraries comes up. I have tried holding down the shift and choosing a library but it does not open. I am beyond frustrated, please help.

    Hi, welcome to Apple Discussions.
    To create or open an alternate iTunes library click the icon to start iTunes and *immediately press and _hold down_ the shift key (option for Macs)* until asked to create or choose a library. Click Choose and browse to the .itl file you want to open.
    The normal layout for an iTunes library is a folder called iTunes which has some library database files in it and a folder for media called *iTunes Media* or *iTunes Music* (if created pre iTunes-9).
    If you move the main iTunes folder elsewhere so that the relative path from the library to the media is unchanged then open using the shift-start-iTunes method then usually the library will carry on working as if nothing has happended.
    If you just move the iTunes Media/iTunes Music folder to a new path then immediately update the iTunes preference for the location of the iTunes Media folder then sometimes it will sort itself out, but often it won't. In this case move the media folder back where it came from, open, test & close the library, then go back and move the whole iTunes folder.
    If the media folder has previously been moved from inside the iTunes folder by changing the location of the media folder and then consolidating to the new location it gets more complicated. In this case the library files can usually be moved to the parent folder of the media folder, leaving the absolute path to each file unchaged but re-esatablishing the normal arrangement of library folder enclosing media folder. Once done the whole parent folder can then be renamed or moved as desired.

  • Can not associate with the access point

    Greetings!
    I am just new here. I am trying to set-up a wireless connection from our linksys router. I recently purchased a linksys wireless internet receiver thru USB connection. Now, my problem is the pc that is supposed to receive a wireless connection is stating " can not associate with the access point". I am not too good about computers, that is why I am seeking you help.
    I hope I can hear from you guys.
    Thanks in advance.
    Cheers!

    Lets start with the bad news, no wireless connection. Good news, fixable.
    Make sure all your security settings on the usb adapter are correct. If router is set for wep set adapter to wep,and so on. Also check all your firewalls, in windows, and on any virus suites that you may have running. Try turning off all firewalls, other than router, and see if that helps. Also download the easy link advisor from the linksys home page. Make sure your ssid, and network names are set the same for router, and adapter.

  • Access points will act as dhcp

  • Access Points do not show in CDP neighbor

    Hi All,
    Last night I was performing mainteance on access points throughout the network. I was converting them from Local to H-REAP to allow for vlan support. The maintenance went well however afterwards I've noticed access points are not showing up in CDP neighbor and with a "show power inline" the access points shows as a IEEE PD. This is causing some weird issues where a client can connect but then will lose it's DHCP address. The problem happened on 9 of the 12 floors that I did this on and there is no configuration differences and bouncing the access points did not resolve the issue. The access points do show a blue light.
    Has anyone ever experienced this before? If so what did you do to fix it?
    I have a mix of 1131 and 1142N access points on a 4402 WLC running version 6.0.188.0.
    Thank you,
    Chris Pratt

    The maintenance went well however afterwards I've noticed access points are not showing up in CDP neighbor and with a "show power inline" the access points shows as a IEEE PD.
    I see all the time.
    "sh cdp neigh" shows nothing and "sh power inline" shows the port connected to the WAP as "IEEE".  This is mostly caused by faulty cabling.  If you have the right Cisco switch, you can test the cable using the in-built TDR feature.
    Here's how you do it:
    1.  Command:  test cable tdr interface
    2.  Wait for about 5 to 7 seconds;
    3.  Command:  sh cable tdr interface
    4.  Please post the complete output.

  • Access point are not coming up after upgrade image of WLC

    Hi,
    I have AIR-WLC4402-50-K9 WLC i that current IOS is 7.0.98.218 and i upgraded with 7.0.116.0 IOS but after upgrading and reboot the WLC from 15 access point 3 access point are not coming up and 12 are coing up and working fine (4 1142 and 11 1131 series access point) 3 which are not coimg is 1131 series access point. when i login with console to 3 access point its rebooting 2 times and coming on ap: prompt.
    In between that i reloaded the WLC one more time because from 15 acess point only 4 aceess point are came up and i also cleck the show boot on wlc its output is
    7.0.116.0 (default)
    7.0.98.218 (active)
    so i reload  the wlc and checked out of 15 acess point now 12 acess point are up and still 3 are not. And i also checked the output of show boot command its
    7.0.116.0 (default)(active)
    7.0.98.218
    So i things its because of when 2nd time i reload the wlc the remaining 3 access point are getting image from wlc but because of reload its connection should be loss and error loading flash error are coming on acess point.
    After that i recover the IOS for access point and convert into autonomus and from autonomus convert into Leightweight Access point. I also attached the procedure for recover the ios of access poing
    But my question is why this 3 access point are not coming up is this happen's after upgrading wlc can any one please send me Step by Step WLC S/W Upgrade' process and if this this happens some time please send me any doccument related to this.

    Sunil,
         When you rebooted the controller did you do it from the Web GUI, the CLI, or did you physically reboot the controller? I believe and maybe incorrect but if your getting the ap:  < prompt > that means that there is no firmware on the unit. If you have restored these to functioning autonomous unit and then re-converted them to Lightweight and it's still happening then we need to look at a debug output of what is happening when those AP's attempt to join the controller.
    The capture you attached shows that it appears to join the controller and get a config, but are you saying that when it reboots again it stops working?? the other thing I would reccomend is clear out the flash memory since your capture shows the possibility that there are several copies stored there.
    Hope this helps.

  • WRT160N Useable as a switch/access point but not as an internet gateway?

    Greetings,
    Can anyone tell me if it is possible to use a
    WRT160N wireless N router as just a switch and wireless LAN access point and NOT as an internet Gateway?  I have a LAN that is not connected to the internet that uses a Linksys switch and I need to get a wireless access point setup so that I can attach a computer wirelessly to this LAN.    Occassionally I connect the swich to another router that does have internet access, but in general the LAN is not connected to the internet router.
    Thanks! 

    You can use WRT160N as a switch...Connect the LAN to the Ethernet port of the router and change the ip address of the linksys router in the range of the LAN ip.

  • IOS Access Point Bombards TACACS+ Server with Requests

    Problem: When using the web GUI to manage an IOS access point such as the AP350, AP1100, or AP1200, and when using TACACS+ to authenticate the HTTP accesses, the access point will send numerous authentication requests to the TACACS+ server for each web page accessed.
    Workaround given by cisco was to use single-connection tacacs server.
    My question:
    How to implement this command? Is it as below
    "tacacs-server host x.x.x.x single-connection port 49 key test".
    I've tried using this command but still getting numerous authentication request.
    Any help?
    regards,
    Ganesh

    We experienced similar problems. We were instructed to use local authentication at the current time. Something about HTTP requiring authentication for each part of the page that accesses data. The configuration line is:
    ip http authentication local
    The single connection did not help. We were also advised that if we required ACS HTTP authentication to use RADIUS because it scaled better than TACACS and would not be as impacted as TACACS. If neither of these are an option, another workaround is to, disable logging "passed authentications". We tested this and it prevented our ACS server from pegging the cpu, memory and I/O write queues. We opted for local authentication because the lack of "passed authentication" logs impacted our troubleshooting.
    Good Luck

  • MBP will not register with iCloud servers (and most iCloud features + Handoff and Continuity do not work)

    Hi all,
    I have an extremely strange issue on my rMBP which has not been solved yet despite over 2 hours on the phone with Apple support, and another hour after being put through to a Senior Advisor, and several online chats.
    I have a Apple Certified Refurbished Late 2013 Retina Macbook Pro, which has a 2.3Ghz i7, 16GB of RAM, 500 Flash Storage and the NVIDIA discrete graphics. It was purchased in December 2014 on the Apple Store. It is running 10.10.2.
    For some reason, my computer WILL NOT register with iCloud. Messages and Facetime both would not work, my iPhone 4S which is capable of text message forwarding would not recognise it and allow me to turn it on. Handoff, Continuity and Instant Hotspot - basically any of the features to do with iCloud or connecting to another device - do not work.
    Originally I believed it was just an issue with Messages and Facetime so I reinstalled the OS back to 10.10.1, but that did not solve the problem. All my Messages contacts kept on coming back as 'not registered with iMessage' and I could not turn on SMS Relay either.
    I contacted Apple on Wednesday night and ended up talking to several different people, the Senior Advisor was the most helpful - really tried to help me figure out what was wrong, and to fix it - wonderful help, really was. They used screen sharing and were quite confused. They figured out as well that Handoff, Instant Hotspot, and all those other features don't work either. At this point, they made me update to 10.10.2 to see if it was an issue with the update, but to no avail.
    Eventually, the SA checked my iCloud account and saw that the computer hadn't even connected to iCloud, and wasn't even showing up as one of my devices, despite the fact that I had signed into iCloud on this computer.
    The SA told me that he suspected it must have been something to do with hardware, but didn't know what it could be. He said the only time he had seen this before was on a refurbished laptop when the serial number hadn't been put back on, but my serial number was there, so he said it must have been something to do with Bluetooth or Wifi.
    Wireless seems to work completely fine, but there is a strange thing with Bluetooth in which within System report says that the computer is not discoverable or connectable, despite the fact that in the Menu Bar it says it is on and discoverable. It becomes discoverable and connectable once you toggle the switch in System Preferences.
    I was planning to book a Genius Bar Appointment as suggested by the SA, but something strange happened today - all of a sudden, some (not all of them) of my iMessages from earlier today came through. Still no working Handoff or Facetime or Continuity, but now I am starting to wonder what is really wrong.
    Despite the fact they said it was hardware (especially Bluetooth), what could explain why it (seldom) or will not register with iCloud? Can anybody shed some light on the situation and whether a Genius Bar appointment could help fix it?
    Cheers and thanks in advance.

    Needed to add some clarification here:
    iCloud shows me as signed in, but Calendars are NOT checked
    Internet Accounts shows Calendars as syncing

  • My Apple TV (1st Gen) will not synch with iTunes on my Laptop

    I've been trying to do this for a while, it shouldn't be too difficult i think.
    All i want to do is synch all the content on my laptop with my Apple TV (and vice versa) so all the content including photos and home videos is the same on both my Apple TV and my laptop.
    Some points:
    There's enough hard drive space on both
    I'm using Windows 7 ultimate on my laptop
    The correct port exceptions have been added to Windows Firewall
    I have purchases on both my laptop and Apple TV from the iTunes store
    We're using a wireless network and it while it's possible to get them both cable wired, it would be a pain
    Home networking is set up in iTunes on my laptop
    I've set up my Apple TV to synch (not stream) with my account on my laptop
    Both iTunes and Apple TV are up to date with their downloads
    I think that's it - am i missing anything, or should this now just work?
    Cheers
    David

    As per the question, really...
    "My Apple TV (1st Gen) will not synch with iTunes on my Laptop"
    There's no error messages
    Only the films i've bought on my AppleTV appear on my AppleTV
    It's been synching for over 4 hours and hasnt got past the first film and the progress bar is not moving
