E1200 Working Fine but DHCP only shows two of four connected

Would appreciate a bit of educating.  My router is connected sucessfully with two computers via ethernet, one printer by ethernet and one Nexus 7 by WiFi.  However if I check Status | Local Network and click DHCP Client Table, I only find the two compujters identified.  Printer is no where to be seen but working fine on 121.168.1.140 and Nexus is working fine via WIFI butagain not shownn.  Tried to give them their static addresses but that killed so game up.  Been coding for years but obvioulsy know nothing about networking - appreicate and offereings.

Don't go crazy over this. The explanation is simple: it's a firmware bug.
I've had this happen countless times. Sometimes devices do not appear at all in the DHCP Client List, but more often, they disappear misteriously from the Wireless Client List (accesible from the Wireless MAC Filter page) even when they are connected. If you want to make sure what's connected to the router at a given moment, it's best to perform a power-cycle before checking.

  • I have a pc running windows 7.  I got an Airport Extreme 802.11n Wi-Fi and the printer is now plugged into the Airport.  The wireless router works fine but the printer shows as offline in control panel and in word. The printer is a HP LaserJet CP1525nw.

    +For now I have it set to Share Public IP address - Is this correct for my Network Setup with The Airport Extreme being the only router being used ?+
    This would be the correct setting if the AirPort Extreme is connected to a simple modem (one ethernet port).

    5 GHz name indicates that you have elected to use the option to assign a separate name to the 5 GHz network. This will allow you to "tell" compatible computers to connect to that network, rather than the slower 2.4 GHz network
    Use Wide Channels is recommended for 5 GHz operation.

  • XE locally works fine but I can't establish any remote connection

    I have installed XE on XP SP2 Pro. (Computer1)
    I can connect from sqlplus in a command window with system/psw ok. and I type the command "EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);" and was executed ok.
    I ran "tnsping XE" and respond ok.
    Thus the Listener seems to be working fine.
    In other computer with W2000 Sp4 (Computer2) and oracle 8.1.7 I have created a TNS:
    ToComp1 =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = COMPUTER1)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    I ran the command "tnsping toComp1" and send the error:
    TNS-12535: TNS:operation timed out.
    Somebody have an idea what's wrong?

    On the server with XE:
    goto your Database Home page. Loging using system/pwd. Once you get the next screen, goto Administration-->Manage HTTP access, enable the radio button " Available from local server and remote clients". Apply changes.
    Try from the client. If no luck, then goto the firewall settings on server
    Exceptions tab-->Add port-->type name and port number, in this case 1571. if needed, click on Change scope, check "subnet only" or "custom list" and give the IP address(s) of the computer you are trying to connect from.
    If it still does not work, then goto the XE client and in the tnsnames.ora, change the host ="name of the computer where XE server runs,with or without domain name".
    Try now from the client, it should work.
    Cheers.

  • I have an old iPod Classic that still works fine but it is having difficulty establishing a connection to my computer.  It will make an incomplete connection but it takes a long time and the computer hangs up until the connection is made. iTunes can't see

    I have an old iPod Classic.  It still plays the music on it out of either port.  It is having trouble connecting to my Windows 7 (64bit) computer.   It takes about 30 seconds or more to connect and hangs the computer until it does.  Even though it shows up in connected USB devices and in Windows explorer it doesn't seem right.  Sometimes it does not make a connection and when it does make a connection iTunes cannot detect it, even though iTunes sometimes automatically launches when I plug in the iPod.  I've tried two different sets of cables with the same results.

    Check the iPod Hardisk health with the iPod  Disk Diagnostic, as posted by tt2
    https://discussions.apple.com/message/17776595#17776595
    It wont fix your problem, but may tell help troubleshoot, why it is freezing iTunes, especially when the Pending and Realloc numbers are high.
    have a nice day!

  • I have 4 flash test files.  Firefox does fine butv IE9 only displays two of them

    I have 4 flash test files.  Firefox does fine but IE9 only displays two of them. These display vertically and are just Flash moves of rolling text.  Firefox diplays them fine but IE9 only shows two to them: 1 and 4a.
    flash_words-1.swf
    flash_words-2a.swf
    flash_words-3a.swf
    flash_words-4a.swf
    Can anyone tell me how to fix it so that IE9 displays all four  of them?
    The URL is http://www.manhattes.com/home.html

    On 1 and 4a you are using the gobbledegook of
    AC_FL_RunContent
    for Flash detection.
    while 2 and 3 do not.
    AC_FL_RunContent is a pretty old embed method so either apply that method to 2 and 3 or switch all 4 to swfobject:
    http://code.google.com/p/swfobject/
    or simply embed using a single <object> and no IE conditional statements (<!--[if !IE]>-->):
    <object data="path_to_file/file.swf" type="application/x-shockwave-flash" width="insert_width_of_movie" height="insert_height_of_movie">
      <param name="movie" value="path_to_file/file.swf">
      <param name="SomeOtherParam" value="ParamValue">
    </object>

  • Airplay works fine, the rest only sometimes

    I recently got an apple TV. I've got it hooked up as follows:
    +--------------+                              +-------------+
    |              |      +----------------+      |             |
    | Apple TV     |      |                |      | TV          |
    |              +----->|                +----->|             |
    +--------------+      |                |      +-------------+
                          |  AV Receiver   |
    +--------------+      |                |      +-------------+
    |              +----->|                +----->|             |
    | Cable box    |      |                |      | Speakers    |
    |              |      +----------------+      |             |
    +--------------+                              +-------------+
    The receiver has multiple HDMI inputs and switches between them.
    I can use the Apple TV as an airplay receiver for audio and video content stored on my Mac, and control it through the iOS "Remote" app (and to be fair, that's mostly how I use it). That part is fine. It also rolls over to the cascading-photos screensaver if I leave it alone.
    However, the Apple TV's native interface for picking online services, navigating media that is available via Home Sharing, etc, is erratic. If I disconnect it from power and reconnect it to force a restart, that part works fine, but after one or two sessions, the screen is black when I try to access it. Using the remote, I can hear the Apple TV making its usual feedback sounds, so something is happening, I just can't see it. I would prefer not to need to force a reboot every time I wanted to use it.

  • My screen wont turn on, and the screen is black. It was working fine, but then it just turned off. The only way it will work is if I close my laptop, and pinch the two screens together

    You have a hardware problem and you should take it into a apple store to be looked at and fixed.

    Hello there, Srushevics.
    It sounds like you may be having issues with the connectivity of your iPhone with the Bluetooth in your vehicle. The following Knowledge Base article offers up some great steps for troubleshooting that Bluetooth connectivity with your iOS device:
    If you can’t use a Bluetooth accessory or car kit
    To resolve the issue, you'll need to first sign in to iCloud and review your devices:
    Sign in to iCloud on your iOS devices and Macs with OS X Yosemite (available this fall).
    On one of your devices, tap Settings > Bluetooth and look under My Devices. You'll see all devices that are connected to Bluetooth, but make sure that you see your Apple devices that are signed in to iCloud and are using iOS 8 or OS X Yosemite.
    Sign out of your iCloud account from any devices that you don't want to use. To sign out of iCloud on an iOS device, tap Settings > iCloud > Sign Out.
    Then, remove any inactive devices from iCloud:
    Sign in to iCloud.com.
    Select Find My iPhone.
    Select any devices that aren't active anymore.
    Wait for Find My iPhone to stop trying to find the inactive device.
    You should see the option to remove this device from your account. Select it to remove the device.
    After following the steps above, restart the device with the issue. Then try to use it with your Bluetooth accessory.
    Thanks for reaching out to Apple Support Communities.
    Cheers,
    Pedro.

  • I was working on a project in iMovie (10.0.1) and iMovie just crashed. when i reopened it the project i was working on disappeared. in my list of projects it still says i have 3 projects but its only showing me 2. is there any way i can recover my project

    iMovie on your Mac  has nothing to do with iCloud storage.  Download and use Find Any File  to search for your iMovie project.  FAF can search areas that Spotlight can't, like invisible folders, packages and system folders.  If there a file with your file name on it anywhere on the hard drive FAF will find it.
    Do you have Time Machine enabled backing up to an external HD?  This situation is exactly what TM is good at.  It makes hourly backups so you can go back to find and restore the missing file.  All HDs crash at some time or another and having a good backup strategy is the only protection against that.

  • I just installed ios7 on my iPhone 4s.  It seems to be working fine but all of the apps I had previously installed are gone.  They show up in my app store as purchased, but the shortcuts are gone.  Does anyone know how to get the shortcuts back?  Thanks!

    I updated via my iPhone 4s.  The apps were on my iPhone 4s.  That's all the information that I have.  The update to ios7 seems to have gone smoothly - everything else is working, phone texting, email, internet, etc.  But all of the apps I had installed over the past year are no longer showing up as shortcuts.  No facebook, no twitter, no espn, etc.  They are all still listed in my app store as purchased, but the shortcuts and my folders are gone.  Thanks.
