Realtek 8191se in Satellite Pro L640 won't see 5 GHz network

I have a new Apple Extreme Base Station with full support dual band 802.11n.
I set up two separate 2.4 GHz and 5 GHz networks.
The wireless adapter is a Realtek wireless LAN 802.11n PCI-E NIC 8191SE bundled with the laptop when I bought it.
Toshiba L640 sees only the 2.4 GHz network.
On another site, a technician HP recommended upgrading of 8192E Realtek adapter.
What can I do to get 802.11n 5 GHz work?

Hello

The Satellite Pro L640 seems to be a Toshiba laptop we.
In any case, first you must make sure that your wireless network card is 802.11 Wlan N capable.
If the WLan card would support 802.11 Wlan N standard, then I recommend updating the driver WLan.
You must use the most recent driver from the Wlan card manufacturer page.

In addition, you must make sure that wireless network adapter has been configured to use the standard 802.11 N.
You should check the settings in the Device Manager-> card WLan-> properties-> Advanced tab.

  • Satellite Pro L20 won't see WiFi Linksys WAG 354 G

    My L20 don't even see my Wi - Fi point. He can see and connect to Netgear and other (older) Linksys AP but not the WAG 354 G. Other laptops can see the AP. I don't think it's something to do with WEP encryption, because he has yet to see the SSID broadcast which is on. I can't update the Linksys to any newer firmware and 5005 G Atheros chipset drivers 3.1.2.19.1123 or is it 3.1.2.45?
    In any case I never been stuck like this before with laptops and APs-seems a bit odd.

    Hello

    You use the clean option of the Windows operating system to configure the WiFi network or using the Atheros client utility?
    If you use the Atheros client utility, so the windows option must be disabled.

    On the Toshiba driver page I found a new version of the Atheros WLan driver.
    There is a version 4.1.2.71 for 802.11 G standard. You should check the two pilots. Maybe one of these two applications will work.

  • Satellite Pro P200 won't start

    I have an old 1 week per Satellite Pro P200, it turns off when I was just in the start menu, so I was not doing something out of the norm (power cable is plugged). Since then it just won't turn.

    With the connected power cable I have an electric blue, power battery and light (although attempts to restart about 2 the battery light was red, but now blue). The drive light flashes for about 3 seconds each time I try to start and I can hear something happening inside the machine, but after only 3 seconds... nothing, completely dead.

    I tried to remove the battery, wait 20 minutes or more and none of it worked. Anyone have any ideas?

    Seems to be definitely a hardware problem... very bad :(
    Why you visit your dealer for new laptop and ask for Exchange.
    Maybe the dealer will exchange the laptop with a new.

    If this isn't the case, then you must contact the service provider authorized in your country for assistance.
    If you have purchased an extra service on the spot then the technician you will visit at home and will try to solve this problem.

  • Satellite Pro A10 won't boot up - where to get the disks

    I have a Satellite Pro A10 that currently does not start up Windows (XP) as it says

    The following file is corrupted or damaged:
    C:\windows\system32\config\system

    Tools & Utilities CD that came with my laptop has unfortunately been scratched and will not start.
    I have two system recovery disks, which are very good.

    My questions:

    1. is it possible to buy a replacement Tools & Utilities CD-Rom?
    2. If Yes, where to go?
    3. is there a way to restore my laptop without having to reinstall everything completely and lose all my files?

    Thank you

    Post edited by: Stuart_2007

    With regard to the point;

    (a) generally, it should be possible to order the CD of tools & utilities but I ask why?
    (b) you can buy the CD of the ASP in your country
    (c) the older recovery CD is supported by an expert mode. You can use this mode to choose the partition where the OS is to be installed. In this case only, this partition will be formatted.

    But look, man. You do not need to order the CD tools & utilities because on this CD, you will only find the Toshiba drivers can be downloaded from the Toshiba page too.

  • Satellite Pro A10 won't start HARD drive

    I have a Satellite Pro A10 that is not responding. If I have the connected HARD drive I get a ' insert System Disk... "message, I checked the HARD drive with a 2.5" USB connector in another computer and it seems OK.

    The laptop, I cannot change the boot order to select CD-Rom so that I can try the recovery disks. I can't get into the BIOS, but the Boot Priority option is not selectable.

    Then put it in the laptop, insert the bootable CD and try to boot from the drive.
    As mentioned you could press the C button immediately after you start the laptop

  • Satellite Pro 4600 won't start

I can plug in the power cable and the lights show the battery is loaded or loads, the power is connected. When I press the button I get no sound from the laptop (no fans or HARD drive) and there is nothing from the HARD disk (no light whatever it may be), but the "On" indicator light turns green even if nothing else happens. Someone at - it an idea what could be wrong with that, and if/how I could fix it?

    Thank you, Adrian

    Hi Adrien,.

    As a first step to diagnose your problem, I suggest you to unplug the unit from AC power and also remove the battery completely. Reconnect AC power and try to turn on the unit. If it works then stop it and reinstall the battery and try to turn on the unit again.

    If the procedure above does not solve your problem, then it is likely that there is a problem with the internal components of your laptop in which case you will need to be serviced by an authorized Service partner.

    Kind regards

    Hello!

    After the bios update newest to my Satellite Pro U300 (PSU31E) Lan Realtek adapter not working anymore. The map shows in Device Manager, but if I connect a cable, nothing happens (it says no cable connected).

    ipconfig-all says:

    Thanks for your advice!

    Hello

    In your case I would uninstall the Realtek LAN driver.
    Can I visit the Realtek and download and reinstall the latest LAN driver.

    In addition, in the DOS command window, you can try to run this command:
    * Ipconfig / renew *.

    PS: Try to also set the default BIOS too.

  • Satellite Pro A200 cannot connect to the wireless network

    Hello

    I have a Satellite Pro A200 and Tuesday night I was able to connect to a wireless network. I received an update, rebooted and now it doesn t seem to work.

    I can see the wireless networks available via the Toshiba Radar but cannot connect to my usual wireless network.
    Also, the wireless network icon disappeared from my system tray and if I go to Control Panel/network connections, I can't even view available networks because there is no option to do so.

    Any ideas?
    the FN/F8 will work?
    Help! Please, I beg you!

    Have you tried using System Restore and restore the operating system on time earlier?
    Maybe this will remove the update installed, and you can again use the WLAN.

    Hello

    Have you used the Atheros WLan or Intel WLan card?
    As far as I know if you unit has an Atheros WLan card you should always use the Atheros Client Utility to connect to some networks.
    In this case, the option use Windows to configure my wireless network must be disabled. If you the Intel card this option must be checked.

  • Satellite Pro 2100 won't start at all - LED flash

    My SP2100 began to have feeding problems and now won't start at all. The AC adapter green LED is lit, that are relevant lights on the body of the laptop (although the "battery charge" light always orange these days). When I try the switch on, startup begins (in fact succeeded on occasion until this morning), however the battery indicator and the adapter lights are flashing, and everything stops again.

    On the rare occasions when I'll be past this stage, lights blinking, and the system soon shuts down again with a screen message "low battery." Until this morning, he would sometimes settle, the computer remained on, and the lights showed a State of equilibrium as usual.

    Initially I thought that the problem was of course the battery or the AC adapter, but now I'm starting to think that it is with internal PSU of the laptop (although I suspect the battery is probably tour after all this part of loading and unloading).

    Any ideas?

    Hello

    I think you're right. Flashing LEDS are a sign that hardware is defective.
    I can't say what exactly is the problem, this should be verified by a technicain.
    On the other side I don't know if it's worth to repair such an old machine.
