• Satellite T110-11U: WLan connection dropped and very slow performance

  Hi people,

  I use a Satellite T110-11U running windows 7 Home premium.

  After having initially was very satisfied with its use, it now becomes more and more frustrating to use with wifi, with connections dropped and very slow performance.

  I have updated the BIOS and think I have updated all drivers wirelss, but could be the problem. It seems that wireless, software of management is at fault because the networks are detected, but not clinging.

  Any suggestion or tips to try will help save my sanity!

  Thanks for your help.

  John

  > have updated the BIOS and think I have updated all drivers wirelss, but could be the problem.
  If you need to make sure that you use the latest WLan driver.
  The driver can be downloaded here:
  http://APS2.toshiba-tro.de/WLAN/

  The laptop uses the Realtek RTL8191SE of WLan card.
  Please also reset the settings of the Wlan router. I had a lot of problems with my WLan and after the reset of the router, performance problems disappeared.

• How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  I have a virtual network adapter that is created with Broadcom.

  This virtual interface named "BASP eCard" visible on the performance monitor in the category 'Rhythm Pipe' but not in the category "Network Interface".

  This is problematic because the Tx and Rx (bytes received/send in second) is available in "Network Interface" that show physical network cards only.

  Someone has an idea?

  Thank you

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• I have error vowsem216dll come often when you turn it on and when you perform updates

  I have error vowsem216dll come often when starting up and when you perform updates today has 32/ntdll.dll error. How do I sort them?

  Many had / have Windows 98 so far.  He may not be able to access most of the internet, but it works.

  You upgrade the computer to another operating system platform?

  Windows XP is more supported by Microsoft but as long you are able to locate the drivers/software to operate, do. Windows 8 is developing so I wouldn't waste my money on Windows 7 right now.

  Restart the computer and the logo of the manufacturer, start typing F8

  Select Mode safe mode with networking

  Download the following tool and run a full system scan to exclude the malware.  If your system is infected your anti-virus software will have been compromised.

• Process * \MCSHIELD. EXE the nest (428) contained code signed or corrupted and could not perform an operation with a McAfee driver.

  XP SP3 system

  I get warnings like this when Mcafee updates.

  Process * \MCSHIELD. EXE the nest (428) contained code signed or corrupted and could not perform an operation with a McAfee driver.

  Process * \SVCHOST. EXE the nest (1632) contained code signed or corrupted and could not perform an operation with a McAfee driver.

  Is this a problem Microsoft or Mcafee?

  Do I need to fix?

  In the McAfee forums, there are several similar positions such as:

  https://community.McAfee.com/message/241542

  I'll sue your question on in their community, as they already seem to know about it.

  I would also say that, unless you are very fond of McAfee or you are forced to use it, you plan to replace it with something that has a smaller footprint, uses less resources and doesn't have these problems - something like Microsoft Security Essentials, you can get here:

  http://Windows.Microsoft.com/en-us/Windows/Security-Essentials-download

  MSE completed with the free version of MBAM and SAS should permanently keep your clean enough unless you're a daredevil like me:

  Download, install, update and do a quick scan with these free malware detection programs (not at the same time) and remove all threats:

  Malwarebytes (MMFA): http://www.malwarebytes.org/products/malwarebytes_free
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

  SAS will probably report a lot of tracking cookies and you can just let him delete them.

  Even if you keep McAfee, I always supplement it with MBAM and SAS since no single AV program does seem to know everything.  If your McAfee of your system is clean, I would interpret that means - McAfee found nothing, says he knows.  It is prudent to use more than a reputable scanner to get more coverage.

  If you choose to spend (and you can't have both at the same time), you must be sure to use the uninstaller that you can get from here:

• How to use memory and boost system performance by using 8 gb win7 Professional 64-bit

  Hello

  I m using HP430 (I have 3 Basic) laptop with win7 64 bit Professional installed.

  recently, I ve upgraded to 8 GB of ram, but I don't really see the system performance problem.

  Can anyone guide the optimal memory use and improve the performance of the system (file e.g.page, etc.)

  Thanks in advance,

  Prashant

  Hello.

  If, for example, your system was using 2 GB before you upgrade the memory, it will use more than 2 GB.  The only time where you would see that a performance gain would be if you had only 1 GB in the system and the system was attempting to use 2 GB.  If you had more that what you were using in the first place you will see no difference.  8 gb is a lot of memory for normal use.  At most I use about 3.5 GB and it is with some powerful applications running.

  See you soon.

• Confusion on table VAAI and EMC

  I have a question regarding the use of the VAAI and an EMC VNX. So, since the host command line you can check the status of vaai and it shows different vaai components that are supported. Just because they are caught in charge doesn't want to say vaai works, right? I saw some documentation showing the use of AUVS to install the plugin vaai, I wasn't sure how all this works. I guess with all the tables, if they support vaai to install the plugin. It is not something that is just Bay storage aware, is it?

  Generally, you don't have any special plugins/VIBs side ESXi operate VAAI with specific storage devices. This is all implemented SCSI standard controls that the storage array is supported or not.

  I have a question regarding the use of the VAAI and an EMC VNX. So, since the host command line you can check the status of vaai and it shows different vaai components that are supported. Just because they are caught in charge doesn't want to say vaai works, right?

  If the output of get esxcli central storage device vaai situation indicates that VAAI is supported for ATS/Clone/Zero operations (Delete a bit is another story), so you can safely assume THAT VAAI operates.

  To confirm this, you can check esxtop (r) while you clone a virtual machine or create a disc of eagerzeroedthick:

  vmkfstools 5-G - c-d eagerzeroedthick /vmfs/volumes/MY_VAAI_DATASTORE/testdisk.vmdk

  While checking the view of storage (r) esxtop ('u') device and add fields for the display of stats VAAI ('f', 'o'), remove other fields if it does not fit on your screen. While the disc is being cancelled, you should see that MBZERO/s for the LUN is high and the normal MBWRTN/s meter shows no significant activity.

  If VAAI is not actively used, the command vmkfstools above creation of the disc will result in normal writing not discharged and the counter values will flip over.

  Also know that for copying/cloning between VAAI capable LUNS, source and destination must be the same version major VMFS and blocksize, and two LUNS must be managed by the same storage controllers. Otherwise, it will automatically change back to not unloaded read/write operations on LUNS.

• Is there a difference first and after the Performance of the effects in terms of CPU intel or AMD?

  Is there a difference first and after the Performance of the effects in terms of CPU intel or AMD?  Forget about the speed issue, assume that the processors are of comparable speed and also assume that the system is built beyond recommended configuration.  When it comes to reliablility and performance of each processor, work and managing data with CS5 is there a difference?  I am looking to build a computer with several CPU i7 so if outside as well (unless you can convince me that don't have a single processor is better than building with multiple) thanks for reading and I look forward to any help you can give me!  Bow.

  The test of disk i/o is 59; 58; 00, the MPEG2-DVD test is 2; 36; 04 and H.264 test - BR is 52 00

  What does it mean in real life? Hard to say how to look your timelines of real life and how leading practice comparisons, but I think that the H.264 timeline is much more demanding that 95% of users would meet. If you have CS5, you can download the ZIP file and take a look at all the effects and transitions used with alterations of Bezier curves in many and with all the different formats used in a single edit.

  There is one thing that you should keep in mind. The MPEG2-DVD H.264 - BR are directed to display the CPU/GPU performance and memory, but in real life, exporting to BRD involves also large (20 + GB) exports the disk, one of the things not measured in these two tests. This means that the high score of Juggernaugt in the H.264 test is only part of the story. We must also study the performance of disk i/o when exporting large files.

  My disappointing score on the H.264 test is caused by the lack of carrots, the memory and the cache limited on the 920. OTOH, price/performance wise I know that I prefer my setup the Juggenaugt.

• Satellite A205-S5864 - stop itself and the slow performance

  I'm new to this forum, so help me out anyway you can.

  I noticed that my Toshiba laptop showing odd behavior lately. She recently began to stop himself suddenly without warning. We arrived at the point where it is a regular occurrence. I don't know what it is, if the computer is starting to show it's age, or a hardware problem, etc.. I hope that's not die because this computer begins to happen over two years. The computer knows that he was arrested not because I get the message that this was not decommissioned and how I want to start in.
  I also noticed that, even though I have a core 2 processor, the computer takes awhile to start. I don't know how to improve the performance, because I regularly clean the registry and trash. I have norton 360 along with spyware blaster.

  any input would be appreciated. I will post more details that are necessary.

  Hello

  I m not A205 owner but on my computer Toshiba laptop, I got the same problem it stops and the reason was a higher internal CPU temperature. So I ve looked in the forum and founded an interesting article on the cleaning of a Toshiba laptop. That's why you need compressed air and you can clean without disassembly.
  Check this box!

  Your slow performance it of difficult to say something on this issue, but in most cases it s advisable to reinstall Windows.
  In my opinion the Norton antivirus slows performance a little so I m using the software tool free AntiVir.

  BTW, did you remove Toshiba TEMPRO?

• Presario s4490uk: boot and hard disk performance

  It is an old machine, but generally suitable for use with a Pentium 4 running at 2.8 GHz and 2 GB ram max. The 120 GB hard drive is at capacity and in particular, the startup is very slow.

  I'm not really interested in buying a replacement but rather looking for updates that will give me a recognizable performance improvement.

  For example, is it possible to replace the hard drive with an SSD and it will deliver no improvement in performance. Similarly, a hybrid Ssd (at much lower cost) would deliver all the benefits.

  Had a quick look at site Crucial however it has not offered an ssd for this model of office.

  Also, if I can get an improvement in the performance of the equipment, would it be possible to update the operating system windows 10?

  Very grateful for any advice!

  You are welcome!

  On the SSD, what looks like a very specific procedure, so I think it will be a good idea to contact Crucial support on this issue. They will be able to say with certainty whether it will work or not.

  Regarding the RAM, I suggest you stick to HP recommendations, because even if you decide to run the two modules on the same machine as a whole, it must default to the lowest speed (i.e. in this case the PC2700). However, if you replace the PC2700 PC3200, you will get a slight speed increase, but I can tell you with certainty how it will be, and if it is noticeable at all.
