1131AG keeps disconnecting from 5508 wlc

We have about 20 APs in our network and about 4-5 are 1131AGs and the rest are 3500s.  The 1131s disconnect from the controller for about 2 minutes (i guess it is rebooting) and then comes back up.  This happens every 1-5 days.  I have tried changing the power level and the channel.  I am not sure why the 1131s keep disconnecting.

I checked the wireless tab on the WLC gui and the AP uptime resets back to 0.  So it is probably rebooting/crashing.
I tried pulling up logs from both the APs and the WLC.  The logs stop about 3 months before and then continues right when the AP comes back online (ex.  Apr 14 was the last log then Jul 1 was when the AP reset and came back online and joined the controller). 
Although there is a Jul 5th message:
*Jul 5 16:00:13.121: %CAPWAP-3-ERRORLOG:  Received a upload request from controller for event log buffer

  • Why does my computer keep disconnecting from my wifi?

    Why does my computer keep disconnecting from my wifi?

    Some users with various Wi-Fi problems have reported that they were given the following instructions by Apple Support, sometimes with success. After completing the procedure, you'll have to recreate all your settings in the Networkpreference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
    Step 1
    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    /Library/Preferences/SystemConfiguration
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Reboot and recreate the network settings.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    Step 2
    Reset the System Management Controller.
    Step 3
    Reset the PRAM.

  • Messages and FaceTime keep disconnecting from my MacBook Pro.

    iMessage and FaceTime keep disconnecting from my MacBook Pro. I’ve never turned either of them off on my computer, but every time I turn them back on, they work for about a week, and then I start getting messages and phone calls on my iPhone and iPad but not on my MacBook. Is anyone else having this problem?

    I'll ask the hosts to move this post to Yosemite.

  • Why does my macbook pro keep disconnecting from the internet?

    For whatever reason my Macbook pro 15in keeps disconnecting from the internet everytime it goes to sleep. And sometimes when I wake it up, I have to turn wifi on and off a couple times to get it to detect the right signal. This does not happen with my playstation or my phone so it has to be a problem with the Macbook itself. Can anyone give me any information on how to fix this problem? Anything would be greatly appreciated.

    Hello, amal111.
    Thank you for visiting Apple Support Communities.
    Here is an article that I would recommend going through when experiencing Wi-Fi connectivity issues.  Also, make sure all firmware updates have been processed on the router and the settings have been adjusted to the recommended settings in the second article below.

  • Smart Watch 3 keeps disconnecting from phone

    My swr50 keeps disconnecting from my motoG phone. I haven't figured out the circumstances for this...it seems random...I realise that I haven't had any notifications for a while, and none of the "OK Google" stuff works.My phone app says that it's connected, but it clearly ain't! 

    I wonder why it would disconnect that much,no problem like that on Z1. Do you have any task killers or antivirus?

  • Time capsule keeps disconnecting from the internet

    My MBP was previously connected to the internet via my sky netgear router, with no issues.
    I have recently purchased a 2TB time capsule and connected that to the sky netgear router via an ethernet cable.
    I then set it up as its own wifi network.  Now it keeps disconnecting from the internet every 5 mins or so.  I know that the internet is fine as I can hook up with my netgear router with no issues.  I cant seem to find any settings to play with.  Earlier posts seem to suggest firmware issues, but since this is a brand new MBP and TC, I can't understand what the issue could be.

    Give us the full blown picture of the network.
    What modem? Is it a router?
    Is the TC in router or bridge mode?
    Can you test with ethernet.. does the same disconnect happen when wireless goes down?
    ie is this a router issue or a wireless issue?
    If wireless can you try setting all that is now auto, to manual settings.. wireless channels.. unfortunately I think wireless mode is no longer accessible. Different names for 2.4ghz and 5ghz.
    There are no new drivers.. That would only be relevant to AC wireless anyway.. or the firmware of the TC.
    But you are running the latest firmware.. 7.7.1 which does mention some (rare) disconnections.

  • HP Photosmart Premium C310a printer keeps disconnecting from my network.

    My HP Photosmart Premium C310a printer keeps disconnecting from my network. I have tried disconnecting my Firewall and AVG virus software, all to no avail. Can anyone help?

    This is an issue I have seen multiple times, and telling people to check their network settings, or to fix wireless settings does NOT address the root cause of the problem.   For those who are English-impared, here is a very clear explanation of what is going on:
    The printer is REMOVED from devices and printers, seemingly at random.    This is NOT a problem with "The printer is not printing", where fixing the network or resetting IP addresses will fix it.   The printer is GONE, and needs to be added again.
    I know networking, and at no time should a loss of connection cause the printer to just be removed from Printers and Faxes, Printers, or anything like that.    If the connection is lost, the connection is lost, but the printer SHOULD still be set up in Windows, just pointing at the wrong place(if the IP address has been changed).
    I suspect that it is more likely that the HP Update software is the culprit, and will test that theory today with a customer who has this problem.    It also seems to be limited to the HP Photosmart line of printers, since the Officerjet line does not seem affected by the bug.  

  • PC keeps disconnecting from home hub.

    Got a very annoying problem, for some reason my computer keeps disconnecting from my home hub. Its got much worse recently and I have no clue what is doing it. Sometimes it can stay disconnected for a couple of hours and when you finally get the connection back it says it cant connect to the Internet. Also my network adaptor cant find my hub but it will find my neighbours even though the hub is just down the stairs from my PC. Signal it good-excellent. There are 2 other computers using the same hub but the are totally unaffected by this.
    Would really appreciate some help.

    from your comments I assume you are using wifi 
    you can try downloading inssider3 (istumbler if MAC) and then run it. This will show the broadcasting networks round about you and their channels including your own. If you then enter your router and change your wireless channel to a free or less congested channel.

  • ISE 1.2 rejects RADIUS messages from 5508 WLC

    The setup in ref is:
    WLC 5508 HA pair running 7.6 talking to ISE 1.2 patch 7 (was 6).
    Wireless users are authenticated fine, so the 5508 is a valid NAD in ISE, but...
    When I setup active RADIUS fallback, so that the WLC can poll the ISE servers I get the message:
    "The RADIUS request from a non-wireless device was dropped because the installed license is for wireless devices only"
    Why would ISE drop a RADIUS message from a WLC which is a wireless device?  Surely this is a mistake?

    Hi Nicholas,
    This is a known defect.

    ISE drops keep alive authentications coming from the WLC, with message 11054 Request from a non-wireless device due to installed wireless license.
    <B>Conditions:</B>
    When only a wireless license is install on the ISE and using active keep alive on the WLC.
    <B>Workaround:</B>
    Use passive keep alive on the WLC and not active.
