Satellite Pro L450 - network without WIRE Realtek RTL8191SE adapter: limited access

Hello

Hoping you can help me with my problem with the wifi connection.

OS: Windows 7
Wireless adapter: Realtek RTL8191SE Wireless LAN adapter
Laptop: Toshiba Satellite Pro L450
Wireless router/modem: Cisco

When I turn on the laptop the wifi connection can work for 10-30 minutes, but then the down network access but remains connected with limited access.
Then restart the connection will have access limited the offset.
In addition, sometimes the available wireless connections do not show in the networks available on the windows toolbar.
When you use the Ethernet cable connected to my router there is no problem.

I have searched the forums for help on this and have already tried without success, the following

Updated driver: issue date may 2010
Verify that TCP/IP has been installed to automatically obtain the IP and DNS
Disabled firewall
Reset the modem
Countless reboots of the modem and the laptop

Wireless modem/router works perfectly as I can connect with other devices and laptops.
Is it a problem that we see on a regular basis with this combination of laptop card / without wire/operating system?
Would appreciate any guidance you can give me as it becomes very frustrating.

Thank you

Kieran

Hello

I see you didn't check the BIOS!
Here you can compare the BIOS with the version update available.
If you have an older version of the BIOS on the laptop, then an update would be recommended.
Once the update to the BIOS it defined it please to the default settings (press BIOS F9 and save)!

By the way:

Here you can find the latest WLan driver
It s v.2015.1.0427.2010 at the moment

PS: I hope that Windows 7 is up to date...

  • Satellite Pro L450 - automatic change of data encryption

    Hello
    I wonder if anyone can help with a problem I have with a Satellite Pro L450.

    I work in a school and we have a WiFi network. In a particular area, we have 4 laptops that connect to the network wireless without any problem. The problem I have is that the L450 continues to lose its connection and when I look at the properties of the connection, WEP form (which we use) has changed data encryption to WPA - PSK alone. I remove then completely and add it again the network connection and set it to wep and enter my WEP and try to connect.

    In the wireless box, then pronounce the name of my network and not connected says, but at the bottom of the box, it says disconnect? If I then go back to the properties, once more data encryption has changed itself from WEP to WPA - PSK.

    I would be very grateful for any help.
    Thank you
    Paul

    Hey Buddy,

    Which is really strange, but I m wondering your school uses non-secure WEP encryption

    In any case, I recommend an update of page of Toshiba WLAN driver. This might solve your problem:
    http://APS2.toshiba-tro.de/WLAN/

    But before you install the new driver I recommend to remove the old version first.

  • I can't reboot my Satellite Pro L450 - 17L

    OK, before we get into the problem itself, I would like to say that I have not a clue about computers and laptops, etc. So I appreciate without jargon and please keep guides so a fish absolutely uneduated could understand haha.

    Basically, one day I decided that I had enough of my * Toshiba Satellite Pro L450 - 17 L * go really slow, so I went to restore the disc and I do not remember how I did it. Anyway, everything seemed to be fine until it came with a white screen after reboot fully say PLEASE WAIT Finishing installation may take several minutes. Please do not interrupt or shut down the computer!

    I think that at this stage of my laptop turned off because he needs to be plugged in at all times and the coward comes from charger (this is because the battery has been completely drained) and now all I have is a guest account and not other accounts either! I cannot restart the laptop because of this and was hoping if someone could tell me another way I can restart because I can't believe that this is the only way.

    Any help and guides are very appreciated!

    EDIT: I forgot to mention that this white screen appears everytime now and never goes away!

    >... and I don't remember how I did it
    To be honest, it is not easy to say on this issue and in my opinion, you should install recovery image after description on http://aps2.toshiba-tro.de/kb0/HTD1303440001R02.htm

    Don't do anything until your laptop is connected to the power running.

  • Satellite Pro L450 - 13 M - Webcam driver open failed

    I am running Windows 7 with a Satellite Pro L450 - 13M.

    My webcam just stopped being recognized by one of the programs on my system. Skype, Toshiba camera etc etc. One day it was fine, a little later when I tried to use it again once it is stopped. I only use it for Skype usually, so I have no weird imaginative bit of software that could get in the way.

    Uninstalled the Toshiba camera software, uninstalled the drivers. Reinstalled the software of the camera - although there seems to be about 400 slightly different versions. I think I have the right one. TC30049700E.

    Windows 7 has resolutely reinstalling the drivers by itself when I boot. He puts on Sonix 5.8.54.1 driver. If I look at the details, there is a list of 6 files, which look reasonable.

    Checked the device manage, who says "this device is functioning correctly. The problem is, this is a lie!

    Curiously, the microphone works well (I thought this was an integral part of the webcam).

    What I would really like to do is to separately install the device driver, without the software package any camera.

    But to be honest all ideas are welcome. It is very irritating and I'm running out of ideas and I'm about to go far company for 2 weeks and I use Skype to talk to my children. I'm kind of semi technically as you can see, but are not fluent, and Windows 7 is new to me. The laptop came with it, and the webcam was working fine when I bought it at the end of February.

    Hi tsgcjcs,

    At the moment, I can t imagine that this is linked to the new version of BIOS... Usually new versions of BIOS fix problems so I think it was just no chance with the BIOS update and webcam
    But if you want an older version of BIOS, you can get it from an authorized service provider. As far as I know, they have all the old versions of BIOS.

    But before that, try to update the webcam software/driver. First delete and restart your laptop. Then use CCleaner to clean the Windows registry and reboot again. Now, you download and install the latest driver from here:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    As far as I know your model belongs to the series of PSLY1E, then check the page and try this!

    Here's my problem:
    I have a Toshiba Satellite Pro L450 - 16M. My OS is Windows7 32 Bit und my router is called Easybox 602.
    Whenever I use my Chicony USB 2.0 Webcamin Skype or other Onlineapplications my Wlan is turned off.

    I can't turn off and turn on before I restarted my computer. I think I downloaded the latest driver
    from this page. I also fixed my system with the recovery CD. Please help me!

    Welcome them

    Hello

    So with other words webcam and WIFI are not usable more right?
    You wrote that you did an installation of recovery using Toshiba Recovery disk: all devices recognized and listed correctly in the Device Manager? Please check this box.

    Generally the wireless network card can also be enabled by using the FN + F8 key combination.

    If webcam doesn t work I would like to reinstall latest driver of the webcam of the official website of Toshiba.

  • Satellite Pro L450: Wireless card missing or did not exist

    Hello, pls I need help

    my lap is toshiba satellite pro L450 suddenly I don't see the wireless card I check the bios and find this option is turned on also update the bios and the problem still exists and there is no card in Device Manager
    the light wireless always off I do not know what happened? and the function keys Fn + F8 doesnot work I install add package and this doesnot solve the problem

    My guess is that just failed your wireless hardware.

    Windows does not display the device driver if it does not find the hardware.

    See this thread where I make various suggestions and tips:

    Probably the best thing to do is to buy a USB Wireless Lan.

  • Re: Satellite Pro L450 - 13P - CD / DVD does not auto play

    Hello

    Recently, I've provided a customer with a new Satellite Pro L450 - 13P (Windows 7 Professional). He came back to me the a few days saying it was a great laptop but CD / DVD will not auto play. I googled this problem and I tried all kinds of solutions suggested, including the various changes of registry, uninstall and reinstall the device DVD driver, unchecking and rechecking always use AutoPlay box everything has failed.

    I have a Toshiba Satellite A200 (Vista) and thought I would try to insert an automatic game disc in my drive. To my astonishment, my laptop had developed the same problem, it used to auto play, but now it doesn't.

    Any assistance people can give me in this matter is accepted with gratitude.

    Thank you very much
    Mark

    Hi Mark

    As far as I know autoplay can be set to Autoplay settings (Control Panel).
    There you can define what should happen when you insert each type of media or device.
    For example, I have all the options set to ask me every time.
    Have you tried to change these settings?

    Have you tested with different media?

    If you have noticed that mean the same thing on your laptop computer you have tested with the same support as your client?

  • Satellite Pro P200: network connectivity is not stable

    I have a Satellite Pro P200, which was downgraded from Vista to XP Pro SP3 corporate.

    I use a sensitive enough network application that will crash when network connectivity is lost.
    This application has been blocking a lot since I downgraded to XP, so I tried to run a continuous ping that gave rise to many messages Request Timed Out (the maximum number of attempts where I actually had ongoing responses was about 30 but is usually much less).

    I use the driver downloaded from the Support from Toshiba site (Realtek RTL8139/810 x Family Fast Ethernet Nic - v5.664.205.2007), wireless network works fine, tried to connect to the network using a cable and a port different without change, and using a different laptop with the same cable and port works fine.

    The yellow exclamation mark in Device Manager is a memory PCI controller which I believe is for the Intel Turbo Memory, because it is not compatible with Windows XP.

    Any ideas what could be the cause.
    I tried reinstalling the driver several times without success, it is likely to be software partners or could it be a hardware failure?

    I think it's related software and troublemaker is SP3. Test it with SP2 only and it will work perfectly. Friend of mine noticed permanent data LAN transfer interruptions after installing SP3. Remove everything works well again.

    Hello

    I have the same opinion as TOM. It is possible that the overheating is responsible for laptop, closing. If the processor is very hot and before it can be damaged the protection mechanism, switch off the appliance. I'm sure that the device must be cleaned and after that the heat can be removed from the unit.

    If there is no way to clean only contact service partner in your country.
