X100e Hanging and Freezing on Wireless

     There was a different thread addressing freezing and hanging when connected via ethernet; however, I have had ethernet disabled from the BIOS since day one of receiving my system but I found my system to be locking up extremely often particularly when connected to the Wi-Fi at Purdue University.
     For reference:  The wireless network at Purdue University uses WPA-Enterprise with PEAP + Thawte Security Certificate.
     Naturally, I had the latest BIOS (1.25) and had all the updates available from ThinkVantage System Update, but this did not seem to help any - when I was browsing on my university network it would simply hang and freeze up completely every 30 minutes or so, forcing me to restart the system.  It would seem to freeze regardless of whether or not I was even doing anything on the internet.
There did not seem to be any serious issues on my home network, however, which used WPA2-Personal, but I do not really use my x100e at home enough to say for sure.
     I was quite convinced that there was some sort of problem with either the wireless adapter drivers or some sort of power saving feature at this point, so I uninstalled the Lenovo x100e wireless drivers and obtained the newest drivers for the RTL8192SE chipset directly from RealTek and installed them.
     I then went and disabled "Allow the computer to turn off this device to save power" for the wireless adapter from Device Manager.  I also set the wireless adapter to "Maximum Performance" and turned off PCI Express Link state power management from the power manager.  I also turned off idle timers for stopping hard disk rotation, system standy, and hibernation.
Now after this little set of actions I seem to be able to more or less surf and download things stably on my university network.  I must note that, the system will still hang every now and then while I am browsing around.  I don't notice any particular pattern to this hanging; it simply happens when I have a browser open and am surfing normally -  it will hang for about 40 seconds or so (I can move my mouse but nothing will respond) and then it will simply resume normal operation.
So there is my story....
Has anyone else ever experienced hanging or freezing on wireless networks with their x100e?
Solved!

Hello,
So far, my networking results with my ThinkPad X100e have been very good, but I have only used it on a few networks.
Have you tried using your ThinkPad X100e on different wireless networks to see if the results vary?  Perhaps the problem occurs with wireless networks that are configured in a specific fashion or using specific hardware.  Connecting at a local coffee shop or public library or other venue with wireless Internet access may provide a different experience.

  • Adobe Premiere Elements 10 on Mac OS 10.7.2 - Hanging and Freezing

    Hello there,
    While I'm not very knowlegable about video editing software, I do use Premiere Elements 10 to edit videos for YouTube. I recently have been able to record using a device which records in 1080i, 29.97fps and saves as an mp4 file format. I've been trying to edit these files (which can be up to an hour long) in Premiere Elements; however, as soon as a video file from this recorder is imported and dragged into the project, it hangs and freezes. Sometimes, the hang happens when "conforming" the video file; other times it happens when trying to preview the video.
    My theory is that it is due to the file format, or because of the sheer size of the file. The files can be several GBs.
    I have tried to reinstall the program, but this hasn't worked.
    Is there any advice you could give me?
    Thanks,
    LiamWatson28.

    Hey Bill, thanks for the quick response.
    It does use the H.264 CODEC. The project preset I'm using is NTSC-AVCHD-Full HD 1080i 30, although when I import the video to the project, I sometimes get a dialog box telling me that the project settings can be matched to the imported video, which I allow it to do. I have around 250GB of free space on my HDD. I allow the video and audio to conform and such on importing, I do not try to edit the video/audio while it is conforming. I'd also like to add that all files are transferred onto the HDD before the edit.
    My specs:
    MacBook Pro 13" (Late 2011) running Mac OS 10.7.4 (Lion) I apologise, I had this wrong in the title and the original post.
    Intel Core i5 2.4GHz Dual-Core
    8GB RAM
    500GB SATA HDD
    Intel HD3000 Integrated Graphics (if that's any help)
    If there's anything else I need to provide, please let me know.
    EDIT: I just tested editing a 10 minute video with the same file format and project preset, and, while it was hanging as frequently, it would only be for up to 5 seconds. Compared to the 50 minute video I was trying to edit, the hangs were much longer, sometimes becoming freezes.  I know that if there aren't any immediate fixes and using the same video settings, I'll have to reduce the file size by reducing the length of the video, so cutting more frequently rather than recording long stretches.
    Thanks,
    LiamWatson28.

  • Adobe Reader 11.0.03.37 hangs and freezes opening PDF documents

    When opening PDF documents with Adobe Reader 11.0.03.37, it hangs and freezes for a few minutes.  Is anyone else experiencing this and is there a fix or work around?
    We have Windows 7 Professional 64-bit operating systems.  It takes a moment for the Adobe Reader to unfreeze itself but will eventually.
    Thanks!

    Found a fix for my problem.  It wasn't the Protected Mode issue after all.  The fix is to disable In Product Messaging.
    Here is the fix for the problem.  Now maybe Adobe can address this issue in the future release or patch/update.
    Try it on yours and see if it doesn't fix it also.
    The following below link provides the information I am about to share with you.
    But open Adobe Acrobat Reader without opening a PDF file. So just open Adobe Reader application by itself.
    1. Click on EDIT
    2. Click on PREFERENCES
    3. Click on GENERAL Category
    4. UNCHECK "Show me messages when I launch Reader"
    5. CHECK "Don't show messages while viewing a document"
    This should fix your problem as it fixed mine. See the link below for more information. Looks like I will be doing a regedit script for our network users to get rid of this problem. UGGGHHH!!!!!!
    Hope this helps!

  • Firefox hangs and freezes the moment i start it.

    Firefox hangs and freezes the moment i start it (9 out of 10 times it freezes). I have reinstalled it but still it freezes. I removed the antivirus (avira) and firewall (comodo) but no change. Can't even enter safe mode it hangs.
    os win7 x64, amd fx 8350m 8gb ram, firefox version 20

    Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
    You can try these free programs to scan for malware, which work with your existing antivirus software:
    * [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
    * [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]
    * [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
    [http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
    Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.

  • IPod won't sync to iTunes, hangs and freezes

    Part of the way through autosyncing my songs to the iPod, the process appears to freeze, and iTunes will not respond. It doesn't seem to be any particular song, as it's happened on at least three songs at separate times. All of the songs play in iTunes.
    As of yet, I've only been able to unfreeze the computer by force disconnecting the device... very bad for the iPod. I've restored it several times, tried all three USB ports on my computer, and I'm sadly out of ideas.
    I have an 80 GB iPod Video, 5th Gen, I believe, and iTunes 7.2 (34).

    I also have this exact problem. So far, I have:
    1) Uninstalled and reinstalled iTunes 7.2 five times
    2) Reset my iPod countless times and restored it (wiped the memory) twice.
    3) Taken the iPod to Apple, who looked at it and said it was fine
    4) Tried to downgrade back to iTunes 7.1.1, but I can't find a link to it anywhere. I never had any trouble with the previous iTunes release
    5) Since both iTunes and the iPod work perfectly by themselves, I reasoned that the connection between them might be bad. So I replaced the USB cable and tried a different port on my computer. This gave the best results so far, but then the same thing happened. Now when I connect the iPod, it doesn't show up at all on my computer.
    6) Updated Quicktime to the latest release
    7) Yelled at iTunes and the iPod collectively and called them rude names.
    Like the other two posters here, files will transfer fine, then all of the sudden, at some random time, a transfer will hang and the whole program freezes. The only way to eject the iPod is to manually disconnect it, get fussed at by iTunes, and reset the iPod. I'd guess that there's some issue with a buffer somewhere, but it happens randomly. Sometimes, I'll transfer 600 songs plus some videos and it will hang. Next time, it will only transfer 10 songs before hanging. It makes no difference if it's transferring music, video, media purchased from the iTunes store, or music I've ripped from my own CDs.

  • Why my new iphone6 64gb hanging and freezing, and its restarting

    Hi
    My new iPhone 6 were totally stuck and freezing while i using photos or apps. i didn't download more apps and my storage is still remaining 44 GB. When it gets hang it automatically restarted also it take time.
    Please help me,

    TTry the simple first step. Reset your iPhone. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.

  • Hangs and freezes with low CPU and RAM load.

    I have a Macbook Pro (13 inch mid 2012) and I have an issue with slow responses and hangs, especially when using Finder. I have done all of the software troubleshooting that I can think of including Disk Utility (verify and fix permissions, verify and repair disk). I’ve tried safe boot and AHT. All returned a healthy result, but the hangs still continued. The CPU load is less than 5% during these hangs and the RAM pressure is low. There is 100+ GBs of free space on the Hard Drive.
    I used Time Machine to backup my data and I went to the Genius Bar. The representative concluded that it was a bad Hard Drive despite the results from the before mention Disk Utility. I thanked him and decided to install a new 840 EVO SSD myself.
    I booted using the External Hard Drive that contained my Time Machine backup. I formatted and partitioned the SSD using GUID and Extended Journal. I selected to restore the Time Machine backup, but it failed. I do not remember the details of the restore failure since it occurred at 2 a.m. Frustrated, I decided to do a fresh install of Mavericks and restore my data using Migration Assistant at a later date.
    Now I have a new SSD and a freshly installed OS and the problem is the same. What else could be the cause of these hangs and beach balls? A faulty SATA cord? Faulty Logic Board?
    Thank you for your time.

    If the only thing that you have installed on the SSD is the OSX and NOTHING else, then that indicates a hardware problem.  Run the Apple Hardware Test, twice if you have the patience - the extended version.  Note an error free AHT is not definitive.
    Reset the SMC and the NVRAM:
    http://support.apple.com/en-us/HT201295
    http://support.apple.com/en-us/HT204063
    As a matter of procedure I also would boot into the recovery partition and run Disk Utility>First Aid, Verify, Repair and Permissions.
    If there is no change, then another appointment at an Apple store genius bar will have to be scheduled. 
    I know that much if this is what you have already done, but the point here is to clearly eliminate as many possibilities before a genius bar appointment so that they can focus on other potential problem areas.
    I am assuming this is a consistent and constant situation that will be repeated at an Apple store.  If it is intermittent, that can be most difficult to diagnose.
    Ciao.

  • ITunes 10.3.1 64bit hangs and freezes constantly

    Ever since I downloaded iTunes 10.3.1 on my Windows 7 machine I can barely use it!  Everything I tell iTunes to do, whether its adding a song to a playlist, or playing a song, is met with a good 30-60 second "hang" before it performs that command. I have read on the forums that people are having trouble with freezing when performing certain tasks, but this freezes on everything!
    I have tried rebuilding my library and completely uninstalling and reinstalling itunes/quicktime/bonjour/software update/application support. Nothing works.
    Any advice or suggestions? Thanks in advance!

    I have the same issue.  I took it the genius bar and called talked to tier 2 phone support. They have standard thing where you uninstall all apple software in a certain order and then reinstall 64bit itunes.  That did nothing (tried it 4 times).
    I've gotten two clues so far.
    One is that at the store if I plug someone else's iphone 4 in then itunes acts the same way. So it is not the phone. Two is tier 2 phone support told me to try syncing it with a fresh user account (an admin one). I did that and itunes was just fine, it did not freeze.
    So there appears to be some conflict with the software, music files, whatever that is on my current user account (also an admin account).  I ran virus and malware detectors and found nothing.  Now I'm going to try putting my music, movies, apps, etc in the new user account and see if the phone will sync then.
    I know its not much but thats where I'm at. I hope it helps.

  • Firefox hangs and freezes

    I just wanted to say that I solved a problem but wasn't sure how to post. My problem was firefox would hang after being open for a few minutes. If I ever tried to use flash it would freeze automatically. I thought it was a problem with the flash plugin. I would disable it and the browser would stay open and I could surf but not use flash. I have now disabled the plugin container and I am able to use flash no problem while surfing
    To disable, see here - http://forums.mozillazine.org/viewtopic.php?p=9530495#p9530495

    You shouldn't flip the pref dom.ipc.plugins.enabled to true, leave it at the default (false).

  • Firefox uses 100,000 K - 200,000 K memory even in safe mode; hangs and freezes periodically

    In the past week or so I've been experiencing regular freezing and hanging, but only when Firefox is open. The freezing and hanging can affect other programs, but it always starts with Firefox. It can be either a) the browser stops responding, dims white, and the spinning circle appears, b) browser stops responding as does the task bar, can't click on any other open windows and sometimes the task bar dims as well, or c) the screen freezes entirely, with mouse movement not shown (although the mouse does move--it appears to freeze, but if I move it and wait, it'll be wherever I moved it) and if I was loading a page, the loading circle in the tab stops moving as well; it's as if a screenshot has been taken and replaced the screen.
    I'm thinking this has to do with memory usage; Firefox uses 200,000 K memory normally, and starting in safe mode only drops it by 20,000 K - 30,000 K.

    Hello,
    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
    '''Note''': ''This will cause you to lose any Extensions and some Preferences.''
    *Open websites will not be saved in Firefox versions lower than 25.
    To Reset Firefox do the following:
    '''For Firefox versions previous to 29.0:'''
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox"[[Image:Button reset]] button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    '''For Firefox 29.0 and above:'''
    #Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''.
    Now, a new tab containing your troubleshooting information should open.
    #At the top right corner of the page, you should see a button that says "Reset Firefox"[[Image:Button reset]]. Click on it.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.

    I don't want to pay to upgrade it if it's not going to make any difference.  My computer is clean, loads of space available and in good condition.  Whilst typing this the whole program just crashed giving me the 'iMovie unexpectedly quit' popup.  I was expecting it!
