No wireless networks detected even they are available and wifi is turned on

Hi all

I can't see the wireless networks available even they are available, and always I see red x mark on wirelss icon beside the clock.

laptop: HP ProBook s 4540

OS: windows 7 Ultimate

WiFi adapter: Ralink RT3290 802.11bgn Wi - Fi adapter

I installed the latest update by connecting computer laptop eithernet cable and search launch legacy manager, alwas says:

"the best driver for your device software is up-to-date.

Please any idea of help.

Thanks in advance.

Thank you very much for your quick response, actually this problem is solved by changing the country / region of the Device Manager wifi adapter, I tried more region until I had access to available networks.

Thanks again

  • Vista: Cannot see wireless networks - I know they are there.

    I'm contracting at Microsoft and just installed the company issued IT Vista. Everything works fine: I joined the appropriate domain and can access all internal servers and the Internet with the ethernet cable is plugged.

Connection to the WLAN MS requires that I am connected to the correct field in Vista (I am), but I do not see the wireless networks - as if there is no such thing as a wireless NETWORK card.

    I'm not sure that you understand the problem. The connection is down to chance? It happens only in the morning when you open the lid? You would update anything else in time (especially a Windows Update)?

    After the upgrade to El Capitan 10.11.5 shift, Alt and command of my keyboard keys started to act arbitrarily, they are suspended and do not work properly (I already tried several keyboards and is not Firefox or Chrome). This behavior is exacerbated in Illustrator CC, but also affect all programs and even my office. It drives me crazy, does anyone know how I can fix this problem?

    Mi IMac is a 27-inch, late 2013, 3.4 GHz Intel Core i5, and use a Wacom Intuos Pro.

    Could possibly be interfering with the entry Wacom drivers.

    Start safe mode and see if there are still have the problem there. Safe mode is slow and some things do not work, but it prevents some third-party boot loading software. If your keyboard works properly in Mode without fail, this would imply that some third-party software is causing the problem. If so, check the updates.

    It also takes more time to start because the BONE is clean some system caches that can also help.

    It is not good enough, as far as I'm concerned.

    In addition to their money get on your part to do anything of any value,
    If you leave them in your computer, who knows what they were doing or where
    What confidential information they stole.

    So if you have done so, I highly recommend that you do both of the following
    immediately:

    1 do a clean reinstall of Windows.

    2. after reinstallation of Windows, change all your passwords.
    especially one of the banks or other financial sites. Once again, even do
    If you have just made.

    Since they have perhaps installed a recorder of strikes, changing just your
    Passwords may not be good enough.

    I have the problem solved. I deleted the speakers BT in device and East Manager went to add to the new device. He finds the speakers and this time connected and will work perfectly. Thanks for all the help and suggestions.

  • How can I change my password? Please don't link to archived answers, they are inadequate and inaccurate

    Thanks for helping with this. I run Thunderbird on Linux and need to access my corp email account, which requires a password change every 90 days.
    I found this archived solution: https://support.mozilla.org/en-US/questions/1029452
    It points to "how to remove E-mail the password stored in thunderbird:
    https://KB.wisc.edu/page.php?id=19006
    But this info is for Windows, then it could use an update for Linux.
    I managed to delete my old password and restart Thunderbird. But T-bird is not connected, do not ask me for a password and does not silently. I checked and there is no password stored.
    I understand that these things are hard to fix (I'm a software dev), but t-bird does not work for me, without being able to use my password by e-mail.

    do not point to the archived answers, they are insufficient and inaccurate

    The link you provided is inadequate or inaccurate.

    But this info is for Windows, then it could use an update for Linux.

    This info is for Windows and Mac OS. The only real difference is the main menu.
    Windows: Tools - Options
    MacOS and Linux: change preferences (Alt-E).

    But T-bird is not connected, do not ask me for a password

    If Thunderbird can not conect to the server, it will prompt for a password. You must first solve the problem of connectivity.

  • Satellite M300-D4316 - wireless network detected but cannot connect

    Previously, I could use LAN wireless on my laptop but last week because I signed up to a bluetooth connection, Wi - Fi connection no longer works.
    It can even detect a wireless network around me; I don't see every time when I try to connect, & it asks me to diagnose the problem & said something like "the signal is too weak.

    I'm sure that is not the problem of wireless service - all my friends can connect to him!

    What should I do?

    Maybe the wireless LAN tipped off?

    Try to press Fn + F8 to toggle wireless devices.

    Also make sure that the wireless switch is turned on in the front and the sides of the laptop.

    Hi people,

    As a result of a virus, I put my computer to its factory settings.

    Also, my computer can not detect wireless networks more. I did all the required updates and checked the State of the wireless card, but still nothing.

    Any ideas?

    See you soon!

    Hello

    May I ask what system you have installed on this laptop?
    Is - this Windows 7?

    If you are using Windows 7, you need to install Toshiba Value added Package and Support Toshiba Flash Cards for utility work affects FN.

    I m nit course on the WLan driver because different C660-xxx supports various wireless network cards. Perhaps you could provide the name of the complete model of the C660-xxx
    This would facilitate the search for the Wlan driver.
