Satellite L355 - S7900 PSLD8U: WLan sometimes disappears

I searched this forum and found a similar thread (unresolved) on the adapter wireless getting dropped from the Device Manager.

The laptop is a (big BJ) Satellite L355-S7900 PSLD8U-07G01E model # L355-S7900
Vista Home Premium

Wireless adapter is Atheros AR5007EG

Randomly (usually after sitting for a period), the wireless adapter disappears from everywhere, including the Device Manager.
I can go to programs and features and reinstall and it works fine until the next time, sometimes days. Then repeat.

The connection appears in the network and sharing Center & the signal strength is excellent.
This light on the chassis is orange. I think remember it to be green.

This machine had a virus some time ago, I have got rid from Combofix and haven't seen any problems since, except this.
I downloaded and installed a new wireless driver but it didn't help.

Any ideas?

Hello

It s not easy to say that that is the reason why, for this, but in your case would start to update the BIOS. You can check it on the Web from Toshiba site we:
http://www.CSD.Toshiba.com

Before you start the update, close all programs that are running and your antivirus and firewall too.

In the worst cases, you need to reinstall Windows using the Toshiba recovery disc. Maybe the virus did remove or change some important Windows or driver files

    Why wireless sometimes appear and disappear?

    Hello

    The WLan can appear or disappear because of a weak wireless signal.
    My WLan disappear and lose connection if I move to the other room

    But this issue may be related to a BIOS and WLan driver so I recommend to first update the BIOS, then the driver WLan.

  • Satellite L355 - dreaded blue screen - Bios does not end

    I have a new Satellite L355.
    Sometimes at startup I get the DBS.

    Otherwise said, the bios does not end and the screen is blank.
    Laptop repair center replaced the motherboard twice, but I still have the problem.
    I found that if I turn off the power and remove the battery, I can start very well after the replacement of the battery.

    Does anyone know why the battery clears the problem?
    Toshiba technical support often has a user that to clear a trouble report. They must know something.

    Thank you, jack

    > Occasionally when booting I get the DBS

    That would mean that this sometimes happens from time to time but not always
    Is this good?

    I think that it of difficult to say what's going wrong here because the question is not always happens... so it is difficult to replicate it
    Usually if the POST (power on self-test) cannot transmit properly then that would mean that a material error has been detected somewhere on the map

    Maybe you should check if the laptop using the latest version of the BIOS.
    If a new BIOS has been published, then you should try to update.

  • Satellite L355-S7915 - how to install XP?

    I am trying to install windows XP on my Satellite L355-s7915 so I did a little research to find out that it is because I do not have the SATA drivers and neither my XP install CD, so I'll try to fix this problem, I want to try to get it right the first time, so I was hoping to check with smart people on this forum I would like to download the driver appropriate to include on my Windows XP installation CD , and if it is incorrect, to get the right pair.

    Unfortunately I can't link the direct page which has information pilot, but here is the page for the drivers for my laptop
    http://www.CSD.Toshiba.com/cgi-bin/TAIS/support/JSP/modelContent.jsp?CT=DL&OS=&category=&MOID=2346352& rpn = PSLD8U & modelFilter = L355-S7915 & SelCategorie = 2756709 & selFamily = 1073768663

    And this is the name of one I think I need to allow XP to run out of a SATA drive.
    ACHI F6 install Tool(v8.0.0.1039; 10-31-2008; 231K) XP

    It is found in refining the search on the HARD drive. If this is not correct, please let me know, and if you could provide the link or the name of the appropriate.

    Thanks in advance.

    Hello

    Sorry, but I must say that there are already 100 threads here in the forum on the installation of Windows XP with SATA/AHCI drivers and I think that everything is already written in the forum and you can find yourself. Just use the forum search, you'll be amazed how much interesting tips, you can find. ;)

    Here is a useful link on the correct install XP with SATA drivers:

  • Satellite L355 - the PNRP service does not start

    My Satellite L355 can't join a homegroup on my home wireless network, because the PNRP service will not start. The service depends on, Peer Networking Identity Manager, PNID, starts. File missing or corupt?

    Any ideas how to fix?

    Thank you, Jack

    Hi jtorbert,

    Friend of me has had the same problem and it could solve the problem by deleting this file:
    "C:\Windows\ServiceProfiles\LocalService\AppData\R oaming\PeerNetworking\idstore.sst".

    This file has something to do with the PNRP service and after deletion it will be re-created. Generally, this service should work correctly after deleting this file.

    My Satellite L355 will not turn. She lights up indicating that it is powered both the battery and the power cord, but the actual commissioning light won't-is not in mode 'sleep', it's just next door.

  • Satellite L355 disk-read error/no safe mode

    I have a Satellite L355 with Windows Vista. When I start my computer, it says "Reading disc error, press Ctrl alt del to restart".

    I do not have the recovery disk, but I buy the Ultimate Boot CD. I have tried everything out there with no luck. It also doesn't let me start in safe mode. I press F8 at startup and it goes to a black screen with an underscore, and that's all.

    Any ideas would be helpful, I tried and looked everywhere. Thank you.

    Hi MissMandy,

    Why you don t have created a Toshiba Recovery disk?

    Well, right now it sounds like that your HDD is faulty. It is recognized in the BIOS correctly? If so, you could try to reinstall Windows from a Microsoft disc or order you a new Toshiba Recovery disk:

    Hello

    > Nothing present in the work station in BIOS
    Hardware problem, I want to say that if the BIOS does not recognize the CD/DVD drive (no details are listed), then its hardware based question looks like.

    Just a question; The ODD (optical disc) is listed in the Device Manager?
    You see something like yellow exclamation?

  • Satellite L355-S7907 - how downgrade from Vista to XP?

    Hello

    I recently bought the Satellite L355-S7907 and do not like Vista I want to run Windows XP Service Pack 2 on it. Now I tried several methods, first start XP from CD, it loads for a few minutes then I get the blue screen of death, by saying that I should run ' CHKDISK F.
    I ran check disk and my my hard drive is fine.

    The other method I've tried is partition my hard drive then when Vista is on trying to install XP on the new partition. Vista allows me to install on a partition, because "Windows on your computer is newer than the version on CD.

    What should I do here? I don't like Vista and I'd love to have XP working on this laptop.

    Any help much appreciated

    J.B

    Hello

    Downgrade from Vista to XP isn t possible. Therefore, you must make a clean and new Windows XP installation. You wrote that you get a BSOD if you start from XP disc, what code BSOD is it exactly?

    I guess you only need drivers SATA to install XP. Have you installed them?
    In addition I recommend read the discussions here in the forum about it. You'll have hundreds of them! ;)

  • Satellite L450D - 11V peripheral WLAN disappeared

    My daughter has this laptop and lost features Wi - Fi during January 2010. I downloaded the latest BIOS and WLAN drivers, but the device is still missing in Device Manager. BIOS has active WLAN.

    The laptop is running Windows 7, and the device is a Realtek RTL8191SE onboard.

    I'm assuming that a windows update has disabled this as it already had no problems - works fine via ethernet cable.

    When starting laptop, the wireless light comes on but goes off then once Windows is used.

    It seems that there is a similar problem to others - I do not want to reinstall OS because I'm assuming that the updates of windows will do the same again.

    Any ideas - Toshiba problem or problem of Windows 7?

    Hi Gimster182,

    About the disappeared WLAN device, you must check this thread:
    http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=51315&TSTART=0

    So make sure that your WLAN device is activated correctly.

    Have you tried with the factory settings?
