WAP371 client disconnects

I have a similar issue as others have had with the WAP371 and clients disconnecting randomly. most of the discussion didn't have any real content, just said to open a case, which I have not done yet as im still researching this but I wanted to see if anyone has advice on my issue. I have both the 2.4 and 5ghz radios on, connection is good and all works fine. after 1 or 2 days, they just stop passing data. my clients show a connection but I cant do anything with it. I CAN access the AP from them but I have to reboot the AP in order to get network access back. It isn't like clockwork, but it does happen at least every 2 days or so. a reboot fixes it. sometimes, say 1 in 4, I lose complete connection to the ap and it will not rejoin. it DOES show up in the connection list, the ssid that is. the event logs are of little help, not indicating anything wrong. I thought originally channel interference, but ive ruled that out since. also worth noting, this replaced an apple airport extreme ap with the same basic settings. that ap worked fine for close to a year. same client connections, cabling, etc. it has to be something on the ap. tried an older 1.0 and newer 1.1 code. same results. any ideas? thanks!

im using WPA2 AES encryption. there are quite a few BSSIDs in my area, my ap sees around 10, but ive scanned and seen way more. the signal strength is pretty low on them and there are only 2 on my 2.4 channel and they are medium in strength and there are 0 on the 5ghz channel. I do not have band steer on, I believe I had 50ms for beacon interval but I uped it to 1sec. (didn't see broadcast refresh rate). its also worth noting I have a netatmo weather sensor that constantly connects and disconnects (to save power im guessing) below is a quick snippet from the log:

  • Client disconnection notification for NIO server

    A server accepts connections from clients and registers accepted channels for reading:
    while (true)
        if (selector.select()>0)
            Iterator<SelectionKey> iterator = selector.selectedKeys().iterator();
            while(iterator.hasNext())
                SelectionKey opKey = iterator.next();
                iterator.remove();
                if (opKey.isAcceptable())
                    clientSocketChannel = serverSocketChannel.accept();
                    clientSocketChannel.configureBlocking(false);
                    clientSocketChannel.register(selector, SelectionKey.OP_READ);
    . . .One of the server's clients disconnects from it by means of socketChannel.close() while the servert is locked with selector.select() (that is the server have nothing to read from its clients and nobody is connecting to it).Will the server be unlocked when the client performs socketChannel.close()? If so, what notification/exception will the server receive?

    One of the server's clients disconnects from it by means of socketChannel.close() while the servert is locked with selector.select()The select() will immediately return; the corresponding channel will be readable; and the read() will return -1.

  • Mobile based clients disconnecting frequently

    Hi folks,
    I have an 1142 running 15.2.2JB.  I noticed numerous messages of clients disconnecting with the following message:
    %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 847a.885b.622c Reason: Previous authentication no longer valid
    The MAC addresses involved are all associated to various mobile devices...iPad, iPhone, Windows 8 Mobile and Android (MAC above is an Android phone).  This doesn't appear to impact PC's and laptops (both Windows an Apple).
    The devices reconnect immediately and this doesn't appear to cause any problems with anything other than Android devices which register the disconnect immediately and therefore bin anything they're currently doing (for some reason the Windows 8 Mobile and Apple devices seem to be able to cope with the disconnect and reconnect and don't ditch anything network connections)

    Does anyone have any ideas why I'm seeing the message "Could not find station pointer" or any other idea's why this is happening?  A search of the web throws up many threads exhibiting the same symptoms but none seem to have a fix and the fixes there are (disable aironet extensions, extend the WPA handshake and disable guest mode) haven't worked so far.
    Many thanks,

    from that debug, the cleint was in a run state, then there was an EAPOL Start message.
    As Blake had asked, what type of device is it?  specifically what is the WNIC and driver versions?
    Wireless drivers do not get updated with the standard windows update.

    According to the error messages, it seems that the viewstate has become "large". You can try fixing by chunking the viewstate into multiple fields using maxPageStateFieldLength in the web.config:
    <pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest

  • Client Disconnected From Database

    I'm running lookout 5.0 on one computer and logging its citadel to another machine. There is more than one lookout process on the PC that is actually running lookout itself. Different processes are logging to different designated database folders on the other computer. When you can actually get lookout to show the history info (i.e hypertrend data and such) on the computer it all works great. However if you ever restart the computer requiring to shutdown lookout, then the next time it boots up it is nearly impossible to get lookout to display the trend info again. You always get the "client disconnected from database" alarm. All the network paths and folder locations are correct. I am lost on this one.

    Did you get this error every time you reboot Lookout or sometimes ?
    If you get it sometimes:
    Simply delete the /database/ Folder in Lookout directory
    when you restart Lookout it will creat a new one.
    From experience when you get this message the database is realy damage
    i dont know why this happens.

  • Asking about how server can handle client disconnection

    Dear sir/madam,
    i'm doing my final year project and it is about a java client/server big2 game.But now i have a difficulties in dealing with the server side.
    That is about how to take action on the serverside if the client suddenly disconnected.
    I have read many java client/server programming scripts.But all of them doesn't mention this problem.The scrpits only assume the client side never disconnect suddenly.
    I hope if you can give me some suggestions on this problem.

    For my mud written in java, I used TCP/IP for the connections. When a client connects, he gets his own thread. Those threads are held in a vector in a manager class. each tick of the server does a quick run thru the vector and if the current thread/socket its on is null or !isAlive() its remove from the vector(which in turn removes it from getting any more game updates. This removal can be caused by two things. The clients disconnects by accident(kills his game, locks up has an internet connection hiccup, etc.) or he uses the games "quit" method. The quit method calls a method that does any player saving of data, etc then closes the socket, and sets it to null. thus the manager sees this and removes him frm the vecotr list on the next server tick. Seems to work great form a mud and worked really well in a multiplayer applet game I had up for a while.

  • MessageQ keep-alive. Info about client disconnect

    Hi,
    I'm using BEA MEssageQ to recieve messages from clients. But i need information if client is disconnected. Is there any keep-alive mechanism which tell me if client disconnected. Or maybe there is a message to check if client is connected?

    Hi,
    I asked one of the developers and got this response:
    Actually OMQ has no pre-defined keep alive mechanism.  OMQ is always accept the requests from clients passively, it cannot check the connectivity of client automatically.
    OMQ can provide information about the status of the queue that the client attaches. If you can accept the hypothesis that client is connected if the its primary queue is attached, then one possible solution for your request may be: create an application which registers to receive availability (attached/detached) messages of the target queue from local Avail Server process. If the queue is available/attached, it means the corresponding client is connected. And if the queue is unavailable/detached, it means the corresponding client is disconnected.

    My Java Web Service works with ComPorts so I need to close it in a right way when a client disconnects.
    Is there a way to detect in the Web Service when a client disconnects.
    Thank�s you all!!

    So, i want to be able to find out if the client is disconnected without waiting to send or receive data.Use a read timeout.
    how can i change the value of SO_KEEPALIVEYou can't. It is two hours by default and requires privilege to change it, and changing it is system-wide. So you don't want to do that.
    Use a read timeout. Socket.setSoTimeout().

  • Detecting client disconnects

    What's the best way to detect a client loss of connection? I've heard
    you can register for weblogic.accounting.disconnect events or used the
    workspace destroyMonitor method. Which is preferred? The events method
    concerns me because I don't believe it will be supported in the future
    once JMS takes a foothold. Is this a valid concern? Are there any new
    ways to do this?
    thanks,
    Edwin

    I would suggest you try catching java.net.SocketException (Connection reset
              by peer: socket write error) in you doGet/doPost method. This is not a sure
              way though ...

  • Wireless Client Disconnects

    Greetings,
    I have (two) of the latest Intel 802.11n/ac PCI desktop client adapters each connected to a set of external dual antennas.  Both are running Win 8.1, basically they are identical and both are less than 20ft from the ceiling mounted AP.  One client seems to work fine but the other will disconnect at random times at least once a day.  Once that client is disconnected it can’t see any of our SSIDs for 5 to 20 mins. But it can see other Wi Fi signals / hotspots, etc.
    Average RSSI is -61, SNR is 31
    We've been running the following stable configuration for the past number of months:
    - One 5508WLC - 7.5.102.0
    - APs-3602I all running 802.11n (not .ac) in FlexConnect local switching mode
    - Prime Infrastructure 1.3
    - ISE 1.1.3
    We've reinstalled Windows and updated the adapter drivers...no change.  It seems obvious to me that it's a client issue but how can I log and prove it?
    ISE doesn't show any authentications problems.  I've read through other "client disconnect" posts here and made the few WLC setting changes recommended.  I’ve turned on debugging on the WLC for the MAC of that client. The WLC msglog never logs anything against the client MAC.  What other AP or WLC logs or debugging can I look at? 
    Thanks
    Michael

    Create an OPEN SSID and get the client to join.
    Provide additional details:
    1.  debug client ;
    2.  sh client detail ;
    3.  What is the make and model of the wireless NIC of the client?  What is the firmware version number?

  • ARD client disconnected from ARD under leopard after using curtain

    I have just noticed a problem that occurs when I put a client under curtain mode under leopard....the client disconnects from the ARD console and remains in the locked state until I go over and manually restart the system...anyone else having this issue

    Sorry, I hadn't noticed that someone replied...Geez you would think they would get this stuff corrected...Do you know if there is going to be an improved ARD in the future. I manage a lab and apple tools are better and more reliable but still have a long way to go....

  • WAP371 clients constantly disconnecting/reconnecting

    I have a new WAP371 with firmware 1.1.2.3. It's installed on an interior wall on the second floor of my three-floor house. It receives power over Ethernet from an SG200-08P switch. Each radio has a separate SSID. WPA-Personal is used on both. All traffic is in untagged VLAN 1.
    Clients are will not stay connected for longer than a minute or two. The log shows an association, then after usually one or two minutes, the log shows a deauth with the message "Disassociated due to inactivity." Then the very next item in the log is another association from the client. This will persist for a minute or two, and then the cycle repeats, continually and forever. This happens even when there is activity, so "Disassociated due to inactivity" seems wrong.
    Following various bits of advice here, I've tried:
    various fixed frequencies
    all bandwidth options
    short guard interval yes and no
    protection auto and off
    frame burst on and off
    fixed multicast rate auto and 54
    removed 1 and 2 from legacy rate sets on the 2.4 GHz radio
    set broadcast key refresh rate to 0
    disabled TSPEC, scheduler, bandwidth utilization, client QoS, Green Ethernet
    I'm at a loss to figure out how to fix this. It causes activity on the clients to sputter -- I'm seeing a fair number of retransmissions. Occasionally application connections, like streaming video, will reset. Help please?

  • VPN Client disconnection from command line

    Hi,
    I want to connect to IPsec VPN on ISA500 by VPN Client (v 5.0.07.0440, the last version, I think), using command line parameters.
    I can connect with the command:
    "%programfiles%\Cisco Systems\VPN Client\ipsecdialer.exe" -c -user myUser -pwd myPassword "MyConnectionEntry"
    but i don't know the command to disconnect from command lines.
    If I do
    "%programfiles%\Cisco Systems\VPN Client\ipsecdialer.exe" -?
    I obtain the list of parameters
    vpngui [-c | -sc [sd] [-user <username>] [-pwd <password> ! -eraseuserpwd]] <connection entry>
    but I don't unterstand what I have to do... I try every combination using -sd parameter (I think means for silent disconnect), but in every case I can only to show VPN interface  without disconnect anything...
    Can anyone help me?
    Thanks

    Prasath,
    This appears to be a data flow issue.  You need to look in the dataflow log file.  Your information indicates the project name is SAMPLES.xml, and the data flow ID is D20091213_014350765.  Look at the data flow log file in
    C:\dqxi\11_7\repository\configuration_rules\runtme_metadata\project_SAMPLES\D20091213_014350765
    Alternatively, you can temporarily replace the transactional reader and writter transforms with their corresonding batch transforms, and run the job from the Project Architect.  Any errors will be displayed in the Running window.
