Symbol mc9090 scanner and SAP loosing connection

I have some symbol scanner mc9090 and I have telnet connection to server and sapconsole. In every 2-3 minutes i lost connection and i must using 'warm boot' on the scanner. I don't know about reason...Maybe You knows??
please help me...i try some configuration on the scanner and it's not working. When I connect to the telent server from PC, this problem doesn't exists. What can I do??
Henryk

Hi Henryk?  I'm not familiar with this device.  Does this happen when standing in one place or when moving around.  Does it always happen every 2-3 minutes?  You may want to check the signal strength from the access point.  Does it always happen on every device that you try?  Try more than one device, if you haven't done so already. 
If this is not your problem, the next place to look would be the server itself.  Does it have enough memory to handle all of the connections, assuming that your server is providing multiple concurrent sessions.
What telnet are you using?  Geogia Softworks?
Welcome to SDN!

  • Xcelsius and SAP BW Connection.

    Hi,
    I have one query on the xcelsius and SAP BW connectivity.I have  designed one dashboard on the BW connectivity.That is fine.
    My question is  if i export the dashboard in the Power Point or PDF it is not showing the real time data.in this only showing static excel sheet data.
    Is it possible to show real time data in power point based on the BW connection  or users can only access .swf file only by portal.
    Thanks,
    Amit

    This is not possible, see also: Can I  export in Power Point or PDF Xcelsious Dashboard if BICS is used?

  • Crystal Reports and SAP BW Connectivity for OLAP

    Hello,
    Anybody created Crystal reports off SAP BW Infocubes? For some reason I am not able to create or configure BW sever connection. I installed Crystal reports and SAP enhance cd for OLAP.
    Thanks

    Hello,
    I was able to connect and create Crystal report based on Bex query..no connection problem there. But, reporting directly off infocubes, the server type "SAP Business Information Warehouse"(add server option in OLAP connection Browser) not showing up in list of values.
    1. I released Info query for PLE DB for OLAP as per

  • How about the RFID device and SAP AutoId connections?

    Hi All,
    Scenario1 (Ports are enabled from client system): Client m/c is in different location and SAP AutoId Server is in different location. I have to connect the RFID reader and device controller to Client m/c to send the PML message to Server system. Is it possible?
    (Or) Do we need to connect the RFID Hardwares directly to the SAP Auto Id server?
    Scenario2 : I have to connect the server system through VPN, in this case If I connect the RFID hardwares to client system. Is it fine?
    Regards
    Sara

    Hi Stellare,
         I fully agree with Daniela Bork. You've installed 5.2 and you need some preliminary data load like rules, messages etc. as per the installation & config guide. By doing so you're loading standard risks(Global) will be created in the system. This value if you want to check at table level this should be at your DB attached to the Java stack.
       ABAP stack tables are /virsa.... and virsa_cc are java stack tables.  It depends on which version of GRC you're using.

  • WRT110 - I upgraded to new firmware and always loose connection

    My router was running fantastic under 1.03 version never an issue. Then I figured i would check for updates and I updated. I wish I didnt. I constantly loose connection to internet and the router. I tried refashing several times. I read everything I can get my hands on. I would really like to get the previous version firmware bake to 1.03 if anyone knows where i can download it or has it. Any help would be greatly appreciated.
    Thanks

    When you Updated the Firmware of your Router, did you reset your Router. Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
    I think this will solve your problem.

  • Iphone and Ipad loosing connection

    Just switched from a Linksys router to a Airport Extreme and my iphone and ipad seem to have alot more problems staying connected to the Airport than they ever had with the Linksys. Before I never had it loose the network but it happens constantly now. Seems to be an issue much more when not in the same room but farther away in the house, but it does not seem to auto join back I have to manually log back in.
    Is the Airport Extreme more sensitive to placement in the house? The Imac or other devices that are stationary and located nearby the extreme don't have this issue. But one of the reasons I went to the extreme was the supposed stronger signal strength but that seems to be the opposite of what I am experiencing.

    I don't have a direct answer to your question, but I am having problems connecting my iPhone 4 to my Time Capsule. Google "iphone time capsule custer," and look for the thread in the iPhone discussion area.
    Good luck!

  • Symbol MC9090 not connecting to my WRT54G

    I am trying to connect a Symbol MC9090 running Windows CE 5.0 to my WRT54G and all I ever get is "Renewing IP address" in the log on the MC9090.  Is there something I need to allow on the WRT54G to get this RF Gun to get an IP address or is it even possilbe?  My laptop connects to it just fine as does many other laptops so I know it is working fine, just curious if anyone else has tried this and got it to work.  Thanks.

    What is Symbol MC9090 ? Are you trying to connect Wireless/wired to Symbol MC9090 ?

  • While updating my ipad to new software through itunes it got stuck and does not work anymore - it just displays the screen with symbols of itunes and the cable to connect to it - help - what should i do?

    while updating my ipad to new software through itunes it got stuck and does not work anymore - it just displays the screen with symbols of itunes and the cable to connect to it - help - what should i do?

    Disconnect the iPad, do a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. The screen will go blank and then power ON again in the normal way.] It is 'appsolutely' safe!, reconnect and follow the prompts.
    If that does not work then see here http://support.apple.com/kb/HT1808

    Hi, stig2013. 
    I would recommend the steps in the article below.  See the section labeled Verify that the Apple Mobile Device USB Driver is installed > For Windows Vista, Windows 7, and Windows 8 > Update the Apple Mobile Device Driver.
    iOS: Device not recognized in iTunes for Windows
    http://support.apple.com/kb/TS1538
    If you are receiving an error message, find the exact error number that you recieved in the article below and process the steps. 
    iTunes: Specific update-and-restore error messages and advanced troubleshooting
    http://support.apple.com/kb/TS3694
    This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if you manually disconnect the device during the restore process. You can resolve this issue by using USB troubleshooting, using a different Dock Connector or Lightning Connector to USB cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

  • Connection Error between ITS and SAP: R/3 system

    Dear All,
    Recently we have migrated our Backend SAP: R/3 Servers to AIX/Oracle platform. The server landscape is running on two application servers and one central instance with load balancing.
    We have changed all RFC destinations from the SAP:R/3 and ITS side and tested the connection.
    We are not able to login to backend SAP:R/3 server through ITS.
    The following error appears
    "Fatal Error!
    The ITS failed to handle this request
    The HTMLBusiness interpreter failed to interpret the template.
    The internal error message is:
    0x2101: Interpreter: The specified input file does not exist."
    What other changes from ITS side we have to look into or check?
    Regards
    saikat180965

    Hi saikat180965,
    Might be the problem is being caused by missing templates. Please have a look in the ITS traces to get more information about the missing file.

  • HHola I update my Apple TV and I am frozen screen with the photo of Apple TV and iTunes symbol and a cable connected from one to another device, it happens and how to fix it Apple TV

    HHola I update my Apple TV and I am frozen screen with the photo of Apple TV and iTunes symbol and a cable connected from one to another device, it happens and how to fix it Apple TV

    Welcome to the Apple Community.
    If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
    Connect the micro USB cable to the Apple TV and to your computer.
    Reconnect the power cable (only for Apple TV 3)
    Open iTunes.
    Select your Apple TV in the Devices list, and then click Restore.
    (You may already have a micro USB cable if you have a camera or other digital device)

  • Wi-Fi loosing connection every few seconds on my macbook pro and its not my router's fault (running yoseomite)

    Basically I bought my new Macbook Pro retina display in September 2014. My wifi was working perfectly well for about a month or two until Yosemite was brought out. I'm not sure if it was immediately after I downloaded Yosemite or not, but not long afterwards I noticed I was having trouble with my wifi (and not just mine but my schools as well). Every time my computer tries to join the wifi network it will work for a while (5 seconds) and it will say that I have a wifi connection but then it will just stop working and it will say I'm not connected to wifi. A few seconds later and it will then reconnect and say I have wifi. I am fairly certain this is not my wireless router ( a BT home hub) as I have other devices such as my iPhone and a computer which does not suffer these problems. After a while of it loosing connection and then gaining connection it will finally stop and the wifi icon at the top will suggest I have a wifi connection but when I hover over it, I see it says "Wi-Fi:looking for networks..." and then 2 seconds later it will say "Wi-Fi: On" and it will repeat like this for however long I am on the network. When the icon appears to suggest I have a connection I am able to load a webpage but it is slow and watching Netflix can be tiresome. I've scoured these forums for information that will solve my issue however all I have found is outdated information from 2010 or 2012 or too technical information that I can't understand. Does anyone else have this problem, has anyone else found a solution, it would be much appreciated if any one could help me solve t.

    Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
    Step 1
    Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
    Be sure to test on more than one Wi-Fi network, if at all possible. A desktop computer can be tested with a mobile hotspot, such as the hotspot created by a cell phone. If the problem only exists on one network, then the access point of that network should be the focus of your attention, not the computer.
    Step 2
    Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
    Step 3
    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
    Step 4
    Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter  tab, if there is one. Uncheck the box marked
              Wake for Wi-Fi network access
    if it's checked.
    Step 5
    Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
    Step 6
    In the Wi-Fi settings, select
              Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
    Click OK and then Apply.
    Step 7
    Reset the System Management Controller.
    Step 8
    Reset the PRAM.
    Step 9
    Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first. Turn Wi-Fi off and then back on. You'll be prompted for the password when you reconnect. Save it in the keychain.
    Step 10
    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

  • Loose connection between Mac Mini and Apple TV 2

    Help!     I have a new Mac Mini 2.5 ghz running Lion and Apple TV2 hooked up to my 32 inch LG TV.
    Before I got the Mac Mini, Apple TV was running just fine on the same network with my Win 7 machine.
    Ever since I got the Mac Mini and I run the Apple Tv at the same time.  I loose connection on both.  My cable provider replaced the router and all my other Win 7 machines run just fine on a wireless network.  I might also add that when the apple tv and mac mini goes down, my ipad 2 goes down too.  Of course, air play doesn't work .  It comes and goes.
    I have a 2nd Apple TV 2 and hooked that up to the same tv with the same results.  I have called Apple many times.  They are helpful but not been able to solve my problem.   The cable provider and I have traced down to a conflict between the Apple TV, Mac Mini and the IPAD 2 . 
    Does anyone have any ideas what may be wrong?

    I have had multiple ATV's, desktops, laptops, and i Devices all running at the same time without a problem. Typically on a network when you start 2 devices and the connection crashes it is an IP problem. Check the IP address on both devices and see. It is usually easiest to have the router assign IPs automatically using DHCP. The router, computers, and ATVs should also be set to DHCP.
    If everything is set to DHCP try disabling DHCP and assign fixed IPs to each device.
