Bad connection WiFi on my Portege R930-15E

Hello

I have a strange problem on my R930 which I tried to solve already for several months, but could not succeed.

As I recently replaced the WLAN router and the problem remained to the laptop, I know now that it's really the Toshiba which hurts.

Question: The WiFi is on the 2, 4 GHz WLAN and there are only two local wireless networks here in the neighborhood. The intensity of the signal is supperb (5), but the speed of the network status changes in a few seconds between the 26 and 130 MBit according to the diagnostic tool for Windows 7 (without doing anything with Notepad). I would not care about it if WiFi would work well, but it's not.

Download videos from YouTube makes sometimes troubled (videos are stuck) but the most important problem is that access to the data to our NAS is really bad.

I know it can work much, much better that I have also two other laptops that work well, both HP, older than 7 years, shows no such a question, signal WiFi is still at 54Mbps or, on the new, with 150 MB / sec. Other tablets and smartphones also do not have these issues.

I tried already to have different channels, but does not help. I've updated also the WLAN, the last driver of Toshiba seems to be: Intel Centrino Advanced - N 6235 Version 13.03.2012 15.1.0.21. Is this really the last being?

In addition, I found around many problems of WiFi in the Toshiba Internet, but so far, none really match my situation.

But I found that Toshiba seems to have bad WiFi antenna, but I sat just 5 meters from the router, so I don't think that it's a software problem (driver). Operating system is Windows 7 Professional 64 bit.

Do you have recommendations for me what to do?

Thank you

Volker

Hello
Indeed, Portege R930-15E was equipped with the Intel Centrino Advanced-N 6235 WLan/BT combo card that supports the 802.11 A/G/N standards.

The latest driver should be available on the Intel page:
http://www.Intel.com/p/en_US/support/highlights/wireless/can-6235

It seems that the latest driver (at that time) was published at 29/12/2014 and its v15.14.0.1 for Windows 8.1
Anyway, as you can see, this WLan module supports the 802.11A/G/N standards.

I think you should check in the Device Manager-> properties-> Advanced tab WLan card which WLan standard was chosen. Probably, you could change cela a/g or just N

Last but not least, I would recommend allows you to check the WLan Card power saving option.
Option for WLan module energy savings are in the advanced power settings and I recommend you to choose for two profiles (dough/adapter) the performance of the value

  • Tecra Z50-A-14 t - bad connection WiFi signal

    In short.

    Absolutely the same problem with my new Tecra.
    Stable connection by cable.

    Bad connection same 3 5 meters from the router. If the distance is longer, or I use the laptop in another room sometimes it s no link at all.
    The card is Intel (R) Dual Band Wireless AC-3160 and that article how I found the link above.

    All electronic in the work of the House with no problem, but this piece of garbage to Wi - Fi only the same has even after 3 visits in the repair shop. And that s for new out of the box laptop.

    I really disappointed me.

    Hmm. have you noticed the same problem of weak signal using the laptop to the power of the battery as well as connected to the adapter?

    My signal low similar knowledge questions may seem due BOF WiFi enabled power saving settings. This setting can be found in the current power plant? Advanced settings

    On the other hand, it might be possible that there is something wrong with the WiFi antenna cable. Maybe it is not properly connected to the mini PCI module

    In the case of changing the settings would not help you and if your already updated the Wlan to the latest version available, I think that the Toshiba certified maintainer should check the antenna.

  • Can CPU overheating if Portege R930 goes into sleep mode?

    I have an a Portege R930. I run an application of 25-30% of the CPU for long hours. If I put the laptop in mode 'sleep', the calculation get suspended? If not, and it is still running, how the CPU is cooled when the fan is off mode 'sleep'? The CPU can overheat?

    I * don't * want my program from several hours to be interrupted by a detector from overheating. If I know that the program is suspended in mode 'sleep', I fear enter "standby" mode. If this isn't the case, so I'll keep the laptop awake, and if I need to carry the laptop, I'll put it into hibernation.

    The answer seems to be that the CPU cannot fire because the programs are suspended: http://forums.toshiba.com/t5/Port%C3...p/689961#M4014

  • Portege R930 - upgrade the mSATA SSD succssfull

    Just briefly, I wanted to report an SSD upgrade.

    When I got my Portege R930 (PT331E, i7) two years ago, I changed the HD to a PRO 840 Samsung SSD 512 GB (big improvement). Now, this SSD is too small (photos!) and I wanted to increase the capacity up to 1 TB.

    But instead of a new SATA, I decided to go for an mSATA + adapter SATA I felt an mSATA unit would be more "evolutionary" - next update of the laptop for me would be a Portege Z, who use mSATA.

    So I bought a Samsung 850 EVO 1 TB with a Delock adapter/converter mSATA SSD, made a clone of the Apricorn cable and the software switched the SSD and everything works fine (actually a little faster )! At first I tried to use the clone with software from Samsungs migration but this didn t work, maybe I didn t the right version.

    -Now I have a lager SSD that will live longer than my R930. Please note that I'm not an expert with computers - just a happy user Toshiba! Thanks for a good forum with my good ideas!

  • Portege R930 gets hot enough

    My Portege R930 (PT331E - i7) becomes quite warm today, earlier it was very silent, now the fan is 70% most of the time.

    I open the bottom cover and checked the cooling paste on top of the processor - seemed rather dry.

    Should I change the dough? I cleaned the fan.
    What can I do else?

    Thank you
    / Anders

    Hello

    If you have already removed your laptop and cleaned vents and grid cooling cooling you can also change the FAT if you know how to do this. I mean, why not. Laptop is already open.

    Usually after the computer cooling system laptop cleaning should work a lot quieter. A few years ago I did this on my machine. I found so much dust inside which blocked the air flow.

  • Portege R930 brightness increases when the shiny things are displayed

    I use a Portege R930 with the 2nd lowest brightness. I noticed that when something bright is displayed, the overall screen brightness adjusted upwards by about 5 tiny slices to speed increment of 1 / second.

    Increments of brightness are not nearly as pronounced as the steps in the brightness slider, but it's there. And very annoying.
    I can't find any mention of this 'feature' online. Is it possible to disable it?

    Hello

    I put t know if your laptop was equipped with the graphics card AMD but the problem, you take it all sounds a bit like a future provided by AMD GPU called: AMD vari-bright.
    Vari-bright save energy consumption by optimising contrast image on the internal LCD screen AMD computers.

    This feature can be used if the computer is running in battery mode, using the internal LCD only or PowerPlay settings under mode battery is set to maximize autonomy.

    The Vari-Bright feature can be turned on and off in CCC.

  • Portege R930-C086 - how to recover the Windows 8 serial key?

    I have Toshiba Portege R930-C086

    my hard drive is broken, I lost all my data and the original windows 8
    so I want to buy the new HDD, and I want to know how I got my windows 8 key back?

    I don't want to buy the new windows 8.

    Each laptop comes with preinstalled operating system also preinstalled recovery media Creator called tool. This tool can be used to create bootable recovery DVD or USB media. This recovery media can be used in case this recovery HARD drive installation procedure no longer works or if the HARD disk fails, as in your case.

    I presume you didn't create this media, right?
    Is that you can order the original recovery image but is not free.
    More information, you can get the Toshiba service provider in your country.

    I don't know if you can order it on https://backupmedia.toshiba.eu/landing.aspx but please check.

  • error 0xc004e003 during activation of Win 7 Pro on Portege R930 - 17 L

    Toshiba Portege R930 - 17L
    S/N: 5D016093H
    (If I search on Toshiba after SN I only find in Toshiba - Ukraine)

    Bought at the shop online "Sigmanet" in Romania.

    It has a sticker on the back w / Windows 8 Pro (small sticker without product key).
    He arrived with the installation of Windows 8 CD.
    Now, it has been pre-installed Windows 7 Pro x 64 SP1 (this laptop has the right of use of Windows 8 and Windows 7)
    Of course, the preinstalled operating system has been slow and gave errors (pre-installed McAfee antivirus, a bunch of small apps, a.s.o.)

    I reinstalled Windows 7 Pro SP1 x 64 (original CD) on a clean partition.
    I can't activate it with the following text:
    Product key: XXXXX-YYYYY-ZZZZZ-XXXXX-YYYYY
    Product ID: xxxxx-OEM-xxxxxxx-xxxxx
    Error code: 0xc004e003

    Now, I spoke with the Microsoft Romania, they tried to help me, but they failed.
    They told me that the license seems stuck at Toshiba, so they suggested to speak to them (Toshiba) to unlock the license or provide a new product key.

    So, I contacted the seller. They passed me at the service of Toshiba authorized in Romania which avoids to help me.

    Now I'm stuck. What to do or who to contact. Everything is so blurry...

    I appreciate any response you can give me. Thank you!

    > It has a sticker on the back w / Windows 8 Pro (small sticker without product key).
    > Happened with Windows 8 installation CD.
    > Now it was preinstalled Windows 7 Pro x 64 SP1 (this laptop has the right of use of Windows 8 and Windows 7)

    Laptop Toshiba computers are preinstalled with Windows systems that are already activated.
    The stickers that you will find at the bottom of the units are the serial OEM key and these keys don't work in relation to other different systems. The OEM key belongs to the preinstalled image.

    So in case you would use the Toshiba Recovery disk and install Windows system using this disk, the serial key is not necessary.

    According to the technical specifications of Toshiba:
    http://www.Toshiba.co.il/en/laptops/Portege/r930/Portege-r930-17L/ the laptop has been pre-installed with Windows 7 Pro 64 bit.

    This means that Win 7 Recovery DVD was not part of the package. Why?
    because the Toshiba Recovery Media Creator software has been pre-installed on this laptop. The software allows you to create the recovery DVDs containing Pro Win 7 64-bit system and the image that is activated.
