WAP4410N stops responding on large file transfers

Also experience this issue, latest firmware (7/17/2010 version).  Definately related to large file transfers.  Or, viewing videos (e.g. youtube) over RDP.
Only power cycle gets responsiveness back.  Laptops remain connected, but with "Limited Connectivity".

There's a limit of 10MB for a single RTMP message in LCDS, you're probably running into this but you're supposed to get a "TCMessageTooLargeException" when you go over 10MB. I think there might be a bug around bubbling this exception but either way, I think you should try to chop your file in 10MB chunks when using RTMP.

  • TimeCapsule (and AirPort extreme too) hangs on large file transfers

    Greetings,
    I got a following problem. I had install AirPort connected to my router with copper and extend network with TimeCapsule. TimeCapsule have two USB drives attached, AirPort - one USB. When I am transferring a large file, in a magnitude 2-3Gb or multiple simultaneous transfers of smaller files to/from those USB drives, depending on which drive I am using the AirPort or TimeCapsule get crashed. For plain user it is looks like as of sudden, data transfer stops, led in a front keeps green, and I can not reconnect to the drives. If I powercycle TC or AES everything get back to normal. Are there anyone else experiencing the same issues and if yes, what would be solution ?
    Thank you.

    I think we have tried almost every combination of disabling Large Send Offload, TCP offload, IP SEC Offloading, VMQ and Receive Side Scaling possible - in the various places there are - although I will be quite honest - as there are 3 places to do this
    for each Server (the related physical and virtual NICs on the HV Server, and also the NIC in the VM) it is possible we may have missed an iteration...
    During our testing we have noticed that the symptoms of the problem gets worse the higher the transfer speed is. For example if you transfer to the VM from a desktop with a 100Mbs NIC, there will be subtle lag and a transfer speed of say 10 or so KBs ,
    if you use a device with a 1Gbs NIC, you on average achieve 50-70 KBs transfer speeds and the higher the number, the worse the GUI / Server locks up (although the transfer completes just fine).
    We also tried throttling the bandwidth via the 2012 GUI - to see if that helped, but none of the changes we made seemed to work, and we did not have time to try the powershell way of doing this.
    We did replace one of the VM's NIC with a legacy one as part of our testing today, and now data transfers to the VM from a PC with a 1Gbs NIC run slower at around 30-35 KBs and the are no noticeable GUI freezes, although during the large transfer
    it looks like 1 in every 30-40 packets is dropped in a continual ping that runs during the transfer period.
    We have done a lot of cable replacing today (out of diligence) but there seems to be no noticeable issue. We also tried and older NC380T dual port NIC we had available and used the standard driver Windows offered instead of an HP one, but the problem
    was identical no matter which NIC we used.

  • AME stops responding when second file added to queue

    I'm running CS5 on a 64-bit Windows 7 system.
    Today, AME stops responding whenever I try to add a second file to the encoding/transcoding queue. I can add an .avi or a Premiere project timeline (either exported from Premiere or added straight into AME) but if I try to duplicate that item or add a second version, I instantly see the spinner and it the application goes to "not responding."
    I have no idea where to start looking. Any ideas?
    Thanks for the help.

    I have now done an uninstall and reinstall of the entire CS5 Master Collection suite. At first, the problem seemed to have persisted, or gotten worse.
    AME was able to launch and load, and could get to the point of selecting a Premiere Pro project timeline to import, without issue. However, AME would hang if I dragged an MPEG-2 into the queue or selected a timeline to import, and then quickly go to "not responding."
    I have an watch folder in my AME queue and I thought I'd delete it to see if I could do anything in AME. I was able to delete it without issue. I then tried dragging an MPEG-2 into the queue again and, predictably, it hung, went non-responsive and I killed AME. However, when I re-launched AME the watch folder was again in the queue. So I deleted the folder, exited AME and relaunched it. I was then able to import an After Effects comp and successfully encode it, as well as drag in some small MPEG-2s. Finally I risked importing a small Premiere Pro project timeline and it worked.
    Right now, AME is happily encoding a timeline from an old, large and messy project that gets messier every couple of weeks.
    My guess is that there was something wrong with way one of the files or projects I tried to import earlier and, since AME wasn't getting shut down, the troublesome item was persisting (and the problem possibly compounding) every time I launched AME.

  • WAP4410N stops responding very often

    Hi
    We found that they stop responding to any clients so they cannot get IP addresses, but we can ping the devices and enter the administration page. The only solution is to reboot the AP. we replaced for a new one one week ago under warranty period, we have also applied the latest firmware Version: 2.0.7.4 . I still find the same issue again today , any solution? as I checked this forum that many people complaints this product. Cisco support, any solution for me?

    What is the serial number of your unit? Also could you look at the syslogs and attach an copy of them to this post.
    Thanks

  • WAP4410N stops responding with 2.0.0.5

    Any news on this? I have the same problem. After a day or so it just stops responding.
    I recently bought 3 of these to my office.
    Running 2.0.0.5 etc.

    Same problem here as well. I hope Cisco will offer a solution ASAP! I was thinking to RMA this product before warranty expires.

  • Error -1309 large file transfers under Mac OS extended format

    When transferring large video files from one firewire drive to another in OSX panther on Rocstor firewire media formatted in Mac OS extended, I am getting error -1309 and lots of problems. The new 250 gig even became unreadable, data was lost, and I had to reformat. It hung norton disk doctor and sometimes the OS reported that copy times for 7 gig files would be 936 hours.
    This is a brand new rocstor drive, and frankly I do not think the drive is the source of the problem, (but who knows?) perhaps the files have become corrupted.
    For example, if I try to drag a 4.8 gig file from a 75 gig firewire to a 250 gig newly formatted firewire drive, (with 230 gigs open space), it starts copying, then a minute later it stops and tells me the disk is full!
    Neither diskwarrior nor norton disk doctor have found a problem with the firewire media or the files. (well, there was one, "a major error was found in the ALternate Volume HEader Block, last mounted version is invalid", but Diskdoctor corrected this) I have researched error -1309 on the internet, but there is surprisingly only a sparse amount of info about it.
    On the first copy operation a few weeks ago there was not really a problem (about 61 gigs worth of quicktimes). The files copied fine. Now these same files -- some of them, especially the large ones, up to 7.5 gigs, are refusing to copy from the (second or third) generation firewire drive to yet another firewire drive.
    Any insights on this puzzling problem would be appreciated.
    thanks

    Status update:
    With a brand new Rocstor firewire 250 gig drive I am unable to record video without getting a FILE I/O error within 2-4 minutes, or dropped frames. I had just reformatted the firewire Mac OS Extended. This drive is just a couple of days old. I have other Rocstor firewire drives that do not seem to have this problem. I have been using a couple of rocstors for more than 2-3 years. Furthermore, the other rocstor drives also contained the same types of files, in an earlier generation.
    The only I way I could have "contaminated" the newer drives was to attempt to copy quicktime files over 4 gigs to the funky drive. This has happened twice now, once with a 300 gig rocstor "400" less than a year old, and now with a 250 gig rocstor "400" just a couple days old. (Incidentally, I have put in two tech calls to them about this matter this week. Their recommendation was to reformat mac os extended.)
    Well, this is puzzling.

  • Hyper-V 2012 VMs freeze on large file transfers

    I have a small non-clustered Hyper-V Server setup as follows:
    HP ML350p Gen8 Server, 6 core E5-2620 CPU and 32GB Memory running Server 2012 (full GUI) with the Hyper-V role enabled.
    The Server has 8 disks, 1 pair of RAID1 15k disks for the Server 2012/Hyper-V OS, and 3 pairs of RAID1 10K disks for 3 VMs (ie each VM has its own pair of RAID 1 disks). The NICs in the Server are 4 x gigabit ports on an internal
     331i card and 4 x gigabit on an external 331T card. The Hyper-V Server is  not running anything other than the Hyper-V role, the LogMeIn client and Symantec SEP SBE 2013 (with recommended Hyper-V exclusions in place) and
    the VMs are a Domain Controller, a SQL Server and a File Server. Currently all VMs have their own single 1GB NIC connection on the 331T card, all VMs have a single IP address and are on the same subnet, no VLANs are used.
    I have applied what hot fixes I can from a TechNet article that recommended how to setup Hyper-V.
    Initially I had a problem with NIC latency during pings, which we traced to being due to the ML350 Gen8 Server's NICs not liking VMQ enabled. When disabled all looked fine, but we had not yet tried to use the Server in production.
    Recently (getting ready to go in to Production use) we have noticed when transferring a 3.5GB ISO of SQL media to a file share on one of the VMs from a desktop PC that this causes the VM to lock up. The file copy will still complete but the screen freezes
    when accessed via Hyper-V manager or remotely via LogMeIn and sometimes the LogMeIn remote session is dropped too. If you cancel the file copy the console is immediately responsive again.
    Since we built the server a while back, HP had subsequently released an updated NIC driver which we installed and it seems to have fixed the VMQ issue, but with or without VMQ enabled we seem to experience the lockups as soon as we transfer medium to large
    size files. The issues were there before and after we upgraded the NIC driver, we were hoping it would address the issue, but it didn't. These servers are very lightly loaded and the problem occurs even on the SQL Server VM with the SQL service disabled
    (ie the server has hardly anything running at all and the console freezes with a single user performing a single file copy).
    We have 3 VMs on the Server, 2 are running Server 2012 and seem to be more affected, the VM running Server 2008 R2 seems less affected. VM to VM transfers seem to be working better (ie slows down slightly but no lock ups), it is only during external network
    transfers. Also the faster the transfer speed is, the worse the issue becomes. If the file is copied to a share on the Hyper-V Host the issue does not occur, only transfers to the VMs.
    Does anyone have any idea what might be the issue here? I saw a hotfix for 2008 for a similar issue but can't seem to find anything for Server 2012.

    I think we have tried almost every combination of disabling Large Send Offload, TCP offload, IP SEC Offloading, VMQ and Receive Side Scaling possible - in the various places there are - although I will be quite honest - as there are 3 places to do this
    for each Server (the related physical and virtual NICs on the HV Server, and also the NIC in the VM) it is possible we may have missed an iteration...

  • Time Capsule WiFi stops when copying large files to Windows 7 (Bootcamp) using WiFi

    I've got a new Time Capsule (Purchased less than a month ago) and a new Macbook Pro.
    I copied a large set of files (large in QTY & some Large in size > 2GB) to my Time Capsule from a Windows 7 computure via a Wired connection.
    When I access the time capsule from Mac OS X (10.8.2) I can copy all of the existing files to my Mac without any issue (Time machine also seems to be working fine).
    However when use I Bootcamp (Windows 7 Ultimate) from my MacBook (The Time Capsule / Airport software for windows has been installed) I can only copy about 100 MB before the WiFi in the time capsule stops working. The WiFi doesn't just stop working for Windows, it stops working on the actual Time Capsule; I can tell because my phone and iPad both lose their connection and the AirPort Utility on the iPad can't detect the Time Capsule any more.
    The issue is reproducable every time with the set of files I am trying to copy.
    I've called Apple Support and they said there was nothing they can do to help (It took a long time to even convince some one that this is a supported configuration even though the Technical Specifications of the time capsule clearly state that Windows 7 is supported - http://www.apple.com/timecapsule/specs.html "For AirPort Disk with a USB hard drive - PC with Windows XP (SP3), Windows Vista (SP2), or Windows 7 (SP1)")  at which point they told me to take it to a Genius bar. I've subsequently done that and been told that they will not support the Time Capsule because I am trying to connect to it using Bootcamp.
    From what I've seen on this forum some people previously had this issue and worked around it by downgrading the firmware. However, since my Time Capsule is new, I am unable to downgrade the firm ware (& it is the latest).
    Any suggestions?

    No, it's not a Windows driver issue. 1) If it was a Windows driver issue the network copy would drop out on the Windows machine or fail rather than the whole Time Capsule losing WiFi connectivity for all devices in my house. 2) I am able to copy the exact same set of files, via the Time Capsule WiFi, when the files are stored on my PC which is plugged in to the Time Capsule via an Ethernet cable.
    It's not a problem copying the same files from another location on my network with the MBP in Bootcamp therefore it' not a windows driver issue and it's not a network IP issue. It's a Firmware issue with the Time Capsule.
    At best this is a bug that has been reintroduced in the latest firmware which is why the suggestions have been to downgrade the firm ware.
    At worst this is a major security issue with the Time Capsule as copying a set of files from it's hard disk via it's WiFi, using a Windows computer, cause the Time Capsule to be subseptiable and result in a Denial-of-Service.

  • External USB Hard Drive disconnects during large file transfers.

    I have a Western Digital 2TB USB Hard Drive that Ive been using perfectly for a couple of years on my MacBook Pro. A couple of months ago I bought a 27inch iMac and started using it as my main computer. So I had that hard drive connected to my iMac.
    I started to notice that during large transfers (be it many files or 1 big one), usually into the Gigs, I suddenly got a warning message saying that the Hard Drive was inappropriately disconnected. It doesnt appear in Disk Utility so I have to manually connect and disconnect the drive in order for it to show up again on the iMac. I tested it again on my MacBook and the same thing happened.
    Another problem:
    Sometimes it will dissappear from the iMac without a warning message, it just doesnt show up. (Usually after long periods of inactivity). I then have to manually disconnect and connect for it to show up.
    So what do you think? Is my Hard Drive Dying?

    I've been having similar problems with Lion on both external USB2 drive docks and more recently a Mediasonic 4 bay Firewire RAID drive.  It was suggested that powersaving mode shut these down but changing that didn't completely solve the problem.  I'm returning the Mediasonic for a replacement but suspect that it is something in the OS that is causing it.
    If the replaced drive still causes the problem, I'll do a rebuilt of the system, eliminating apps that were migrated over, even though the system is only 5 months old.  If anyone has solved similar issues, please let me know as well.  Thanks.

  • Disk Full Error on large file transfers to 160 Gb classic

    I have around 90 Gb free and when I try to upload a 8 Gb file, it pops up an error saying the disk is full. I wiped all the free space on it, and then proceeded to upload around 15 Gb of smaller files no problem. But every time I try for that 8Gb one it errors on me.
    Any ideas why this is or how to fix it?

    Hi,
    if I remember correctly the iPod for Windows uses the FAT32 file system for its own harddisk.
    The FAT32 file system can only accommodate single files that are smaller than 4 GB. No matter how much free space there is on your iPod, you can't copy files that are larger than that.
    On a Windows PC there is no solution for this as it is not possible to change the iPods File System.
    Regards

  • 2 different WAP4410N stops responding

    Still having issues. I reconnected 4 laptops today on 2 different WAP4410n APs. The user will let me know if they get disconnected. Yesterday I even reflashed the firmward on them. Also in order to reconect to one of the Waps I had to cycle the power.
    The laptops are different
    One is a Dell Latitude c840 w/ Links wireless card and the other is a IBM t41 i believe.

    Just checking to see if there has ever been a resolution to this issue. I have several of these units set up and am experiencing this same issue. I  start them and they work fine for a few days, then nothing. I use WIFI Analyzer on my phone or tablet and they are just not available. If I login to the web interface and reboot the AP it starts working again. At times I have noticed that on WIFI Analyzer I will see the signal suddenly appear normal for one refresh cycle, then drop to nothing for a while, then suddenly reappear. I have screen shots of this is you think it would help.

  • WAP4410N stops responding with SRW2024

    I have the same problem with my two WAP4410N connected to my Cisco SRW2024 Gigabit switch.
    It appears that there would be a time where the PHY's between the WAP and the switch are hung.
    The lights on the Gigabit switch are constantly flashing.
    It is until I disconnect and reconnect the network cable between the WAP and the Gigabit switch
    that the problem is momentarily solved.  Then it seems like another high traffic usage of the
    WAP will cause the connection to hang.  This solutions is totally unacceptable as I am not
    willing to open my wiring closet every time to fix this hang.  Also I've lost precious data
    between my client and server because of this hang!
    I don't think the problem is with the Gigabit switch as I have other Gigabit devices connected
    to it and I never get them to hang like the WAP.
    I saw on the release notes (although the firmware has not been posted) that there is a problem
    with the WAP Gigabit PHY.  From the release notes, it seems the firmware will have an
    option to take down the speed of the WAP Gigabit PHY from 1000BT to 100TX.
    This would be a shame if this is the final solution as one main reason for purchasing the
    WAP4410N is its Gigabit capability.
    Being a networking PHY designer who had also worked on other Cisco products, I'm surprise
    that this problem had not been resolved in their qualification and interoperability lab.
    They should have been able to identify this problem quickly and provide the right fix.
    Cisco please help!

    Hi,
    I was made aware of this issue and the work around of setting copper port seed to 100 meg, just before X-mas.
    (please note: the work around will not advertise 1000M options).
    I didn't even question, if this would be fixed.
    I also have, to coin a expression, have my fingers crossed that the 'fix'  will be expedient, but i have no date.
    We both should check this community site to see if someone has already posed any extra information regarding this issue.
    regards Dave
