Network disconnects when uploading

This is a weird problem that started a few days ago. I'm using a WRT54G with 2 computers. Both of them are using a wireless usb network adapter. I've had this set up for almost a year now with no problems.
All of a sudden whenever I upload to the web, or move files between computers on the network, I get booted off. The connection to the router dies on both computers and comes back on after a minute or so.
I did a live chat with a tech and he suggested upgrading the firmware. I did and it didn't help.
It's very strange. If I do a bandwidth test, as soon as the upload part starts...the network connection dies immediately.
Any ideas?

I had the same problem. Wi-fi will disconnect itself if I upload (or pull file) from a desktop computer with network adapter. So when I'm uploading files, not only my desktop computer, but other two laptops will get disconnected. The only hard-wired computer does not get disconnected. However, I can upload or pull file from my laptop which uses its built-in wi-fi network card.
I just upgraded the firmware for both router and network adapter, followed your instruction, and it did not solve my problem.
How do I force my wireless connection speed to 54 mbps?
My router is WRT54GS.
Network Adapter is WUSB54G

    network disconnects and turns it self off when using youtube app on ipad air

    Hello paulm250m
    Thanks for using Apple Support Communities.
    For more information on this, take a look at:
    iOS: Troubleshooting Wi-Fi networks and connections
    http://support.apple.com/kb/ts1398
    Wi-Fi disconnects or signal strength is less than expected
    Move closer to the Wi-Fi router (access point).
    Check for sources of potential interference.
    Remove any case, stand, or other accessories from your iOS device and see if signal strength improves.
    Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including
    previously connected Wi-Fi networks and passwords
    recently used Bluetooth accessories
    VPN and APN settings
    Best of luck,

  • CNS-9107 : Network disconnected when synchronize with PDA cradled

    We are running into CNS-9107:Network disconnected during synchronization when we cradle the PDA. The problem only happens when the synchronization posts a sufficient amount of data, we saw the problem happened when the post content-length at 62K in my office, and 136K from my home, both are using the same mobile server, which is internet accessible.
    We got err=10035 [WINCE: 10035] in the debug.txt after we turned on debug by adding DEBUG=1 in the polite.txt on the PDA.
    Did anybody run into the same problem?
    Could anybody shed some light on what err=10035 [WINCE: 10035] means?
    Our environment are:
    Server: Oracle Lite 10.2.0.2.0
    PDA: Dell Axim X51v, Windows Mobile 5.0, our application is using Olite C# library to do the synchronization
    Activeync: 4.2
    Thanks in advance.

    I post our findings here, in case anybody else runs in the same problem.
    Possible solution 1: We got some patch DLL(olaes.dll and omcapi.dll) for WM 5.0 from oracle support, it looks promising to solve our problem, hope they will make to the future Oracle Lite release or patch.
    Possible solution 2: In fact, this solution can only be used as a workaround, rather than a solution. After we upgrade the ROM to A12 for my Dell Axim X51v, we noticed there is a new Icon called 'USB to PC' under the Connections settings. We uncheck the 'Enable advanced network functionality', which seems resolve our problem too.
    Hope this helps.

  • ICloud Drive causing timeouts and disconnects when uploading

    It seems that iCloud Drive is set to use the maximum upload bandwidth possible when adding files to it.  I have a home internet connection with fairly limited upload bandwidth (1Mbps - Time Warner Cable apparently doesn't think there is any need for more than that). When I add files to iCloud Drive and they begin to upload, everything else I am doing online quickly times out and eventually disconnects.  As far as I can tell, there isn't any manual control for how much upload bandwidth iCloud Drive can use.  Dropbox and other cloud services have such a setting but it seems that Apple has left this out of their offering.  Has anyone else experienced this?
    It is probably also worth noting that this is the same thing that happens to me when I upload to iTunes Match.  It seems that Apple needs to better handle users with limited bandwidth.

    Hi floorram,
    I'm sorry to hear you are having issues with iCloud on your devices. If your Pages and Word files do not appear to be updating on iCloud Drive, you may find the information and troubleshooting steps outlined in the following article helpful:

  • Network disconnects when speed is changed to gigabit

    For over a year this machine has been connecting to a network at gigabit speed with no problems. Over the past few weeks it started having problems staying connected. All mounted volumes would be disconnected then an error message would pop up saying they were unavailable. No other machine on the network would have any trouble staying connected.
    In the process of working with it I switched the ethernet speed to 100 instead of 1000 in the network control panel. At this point I would see the link status change to active in the info tab of Network Utility. Change it back to 1000 in the control panel and the status would change back to inactive in the utility.
    What can be causing this? No other machine is having trouble like this. Nothing has been changed hardware or cable wise anywhere. Server, switches, workstation have all been powered down and restarted. Once the speed was changed to 100 base all has been fine, except for the speed.
    Any thoughts or insight would be appreciated.

  • My network disconnects when computer falls asleep???

    I am working on Verizon Fios wireless network and my computer loses the network everytime the computer goes to sleep. The only time it works is when I do a full strt up. I have to switch over to to my airport express network after waking the computer.
    Is there some kind of setting I can change to help this stuation?
    Thanks so much.

    Same here on my iMac 2013 running Mavericks. As soon as display goes asleep, Airplay disconnects. Caffeine does not help.
    Unchecking mirroring does not work either, leaving me with a screen resolution that's maybe fit for TV but unsuitable to work with when you want to carry on using your computer while music is playing on the Apple TV.
    I start wondering if Apple is actually doing sufficient testing of their software. These are rather basic errors.

  • Networking disconnects when downloading but otherwise idle.

    Since my "Macbook Pro 15" 2.6Gh Core 2 Duo 4Gb"s  upgrade from Snow Leopard to Mavericks if I am downloading a large file or lots of files over night when I am not using the computer for other things it's wifi network connection drops out(the network panel shows all the settings and the icon on the menu bar shows full strength BUT! there is no network activity.   If I turn the wifi off and on then the network data starts flowing again.
    Is this a Mavericks power saving thing or a bug or both?  Should I report it as a bug? (I think I might)

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Network disconnect when in sleep mode

    Hi all.
    Since I've installed Mountain Lion, any time the computer goes into sleep mode, networking do the same: I cannot download files, when the computer wakeup I have to wait the reconnection before being able to use mail, safari or ather network stuff.
    I did not find any option to set, telling the computer waht to do when in sleep mode.
    WIth Lion and preceding OsX this was not an issue.
    Is there anything I can do?
    Thanks.
    Federico.

    Hi,
    Yes, clear "Allow the computer to turn off this device to save power" in the properties of network adapter\Power management as mentioned in the link provided by arnavsharma, and check if the issue persists.

  • Wireless Network disconnect when plugging or unplugging A/C power on T60

    Wireless disconnects whenever I connect or disconnect the power supply (no matter what percentage of remaining battery).
    ThinkPad T60
    This issue is reproduceable and also happens on my coworker's T60 too.
    Message Edited by perlphp on 12-13-2008 03:14 PM

    I am told this can be caused by Deep Smart PowerDown enabled on the WIRED
    connection, which causes the adaptor to vanish from the list in
    Windows.
    The wireless then disconnects, even though you're not using the wired adaptor!
    To fix this:
    1) Control Panel -> Network Connections
    2) Locate the icon for your wired connection, right click, properties.
    3) Click the configure button top right
    4) In the advanced tab, scroll down the list until you find "deep
    smart power down" (called something different on a T61) and change the
    state to disabled.
    5) Click OK twice.
    This fixed my disconnection problem!

  • Xbox disconnects when laptop connects to network

    My Xbox 360 disconnects from the network everytime my laptop connects. I have static IP on my 360 and automatic IP on my laptop.
    I tried putting my Xbox on automatic, still didnt work.
    I tried putting my laptop to manual - it worked but I can't leave it like this because I connect to different networks (school, home, work, etc).
    Other computers/consoles dont get disconnected when I connect with my laptop.
    Can anyone help me out? Thanks!

    As you are already using static Ip on X-BOX, forward ports 88 & 3074 for the same Ip
    Also try this setting:
    Channel – 1or 11
    Beacon interval – 75
    RTS & fragmentation threshold – 2306

    my ipod classic 170gig disconnects when i open itunes? any ideas? It only happened since i uploaded new itunes version?

    The point is that there are four i product users for one computer in my house, and not everyone wants the same music on their device.  Like I said before, the ipod is not syncing to the new library even though I plug it in when the new itunes library is pulled up.  It keeps syncing to the old library...

    if it is possible to get any event on network disconnection at client sidetahn i can solve the issue.
    Thanks and Regards

    You  must be getting the "NetConnection.Connect.Closed" as info.code in the onStatus for the NetConnection.
    See http://livedocs.adobe.com/fms/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDoc s_Parts&file=00000742.html
    nc = new NetConnection();
    nc.onStatus = function(info){
        if (info.code == "NetConnection.Connect.Closed")
            // Netconnection has closed.

  • Time Capsule WiFi disconnects when a Fujitsu Siemen Laptop with b/g network

    Time Capsule WiFi disconnects when a Windows Vista based Laptop with "b/g" network connects. When i use Macbook with "n" Network.
    Surprising that TC and MacBook both from Apple can't stay connected when Fujitsu Siemens Laptop joins through WiFi.
    I use a DSL Modem (Speed 1 Mbps) connected thru ethernet to Time Capsule on Bridge Mode.

    Yes, n is better, but if you have it running on b/g/n (since you have to with your b/g only notebooks) the n is inactive. Kind of a waste. Others have resorted to adding another wireless router which one set to b/g/n and the other n-only.

  • "Network disconnected during sync."

    We are getting a strange error
    "ERROR",CNS-9107,"07/17/2006 12:03:40","Network disconnected during sync. "
    while synchronizing our Oracle Lite PocketPC application with Mobile Server. This only seems to be happening when we are uploading inspections with photo data, have anyone else experienced this problem?

    During the 'Sending' phase from the client, a packed binary file (created by the composing phase) is being uploaded to the server, where it is then unpacked and the data put into the in queues.
    During 'recieving' the server is creating a packed binary download file from two main sources - the out queue data for the user, and real time queries for any complete refresh items.
    Have you set trace logs to SYNC for an example user? This should tell you whether or not the read of the out queues or complete refresh queries are at fault (you should see a list of publication items, and then the trace for each one in turn as it is processed). If the log shows that it is stopping on one publication item (normally a complete refresh), particularly where you have a long download time, then the query may be timing out.
    If the sync log shows that all PI's have been processed successfully, then the problem is probably related to the send of the packed binary file. Have a look at the sync history for the user, in terms of record and byte count downloaded - is this excessive? Publication items containing BLOB columns (like images) set to complete refresh could be very large
    On the client you should find a file(s) <USERNAME>olres.bin and/or <USERNAME>_olres.bin If you find them, the download at least started. When you say that the user cannot re-sync, do you mean that they get the same error reported? if so try deleting these files and see what happens (a server side error will be within the download file so will not go away until you kill the failed download files), if you still get the error quickly after removing the files, something has broken the activesync connection. If re-cradling the Pocket PC device to re-establish the connection works, then the problem is definitely in the activesync set up.. If it does not, is there anything in your network software that is restricting file downloads or packets?
