  • HP 15 laptop: wifi does not work windows 8.1

    I have Windows installed pro 8.1. I was using wifi on this laptop, it worked fine. However, recently, I see that the Wifi does not work although he shows me the SSID of my network I used to use and also the SSID of the networks of neighbors. (It means that the wifi on laptop chip is capable of scanning the wifi signals and so it works). The same router from which all other Mobile tablets, my home laptop work are able to connect to the wifi network. Only on this laptop I am facing this problem. What may be a solution or what I should try. I tried the steps listed here http://www.fixedbyvonnie.com/2013/10/how-to-fix-limited-or-no-connectivity-wi-fi-issues-in-windows-8...

    Although I have not changed the default settings only steps above on blog, I tried to solve the problem. However, it did not work. Also keys function + F12 on laptop has no effect. The light on the F12 key is always on. However, it is possible to toggle the wifi in the bar of Windows 8.1 charms.

    What should I check?

    I bought an external USB wifi device that solved the problem.  The card wifi on laptop works well, but for some unknown reason, he is not able to connect to home wifi router. http://www.snapdeal.com/product/leoxsys-150-Mbps-Nano-WiFi/1179610?utm_source=earth_feed&utm_campaign=TopPerformersPLAScaling3000&utm_medium=CPC&utm_content=1179610&utm_term=, & campaignid = 350311165 & 28373951005 = adgroupid & adposition = 1o1 & network = g & device = c & targetid = pla-55251503741

  • I am owner of Dreamweaver 8 comes with Macromedia Studio 8. I'm getting worried about the age of the machine which is on. Is there a way to upgrade a laptop Windows 7 which does not involve a monthly rent and allows to work on my website source

    I am owner of Dreamweaver 8 comes with Macromedia Studio 8. I'm getting worried about the age of the machine which is on. Is there a way to upgrade a laptop Windows 7 which does not involve a monthly rent and allows to work on the source code of my Web site completely offline?

    Thank you. Last time I looked into things with the description "Cloud", it seemed to me that you either need to be logged to the software work (possibly validate the rental date?) and/or your content of current things was 'in the cloud '.

    While I don't like the rental model, if I can make it work offline that may be an option.

    Fortunately, the machine still works, so I have little time to decide. It is likely that my existing sites in Dreamweaver 8 will be compatible up with current versions?

  • HP Pavilion 15 laptop: Free WiFi does not

    My laptop (HP Pavilion 15 Notebook PC) does not connect to the internet. The problem started after I downloaded AVG Zen, I have shortly after uninstalled. State of the control of HP network connection arrives with two messages of "IP not subscribed (109). I don't know what it means that this is the first time I saw him. I rebooted the WiFi router and my laptop several times and there was no change. When I troubleshoot WiFi he said it might be a problem with the driver for the WiFi aidapter. I don't know how to solve them. The WiFi icon has full bars but has a little (!) next to it. Someone help me please. I can fix it manually, or do I have to consider for repair?

    In the taskbar, icon search, type recovery.

    Recovery should appear at the top of the search box.  Click on the recovery.

    Then the control panel should open, and you select open system restore.

    Then follow the instructions on the screen to restore your computer to a day that it worked OK.

    Select the closest available restore point to before installing this software.

  • HP Pavilion dv6t-7000 computer laptop with windows 7. Can not connect.

    Have a HP laptop with windows 7 and I can't login.  When I try to log in with my password, permanently, I get the message "the user profile service has no logon. The user cannot be loaded. "What can I do?

    Hello

    The first thing I would suggest to try is the following.

    Shut down the laptop.  Tap away at f8 that you start the laptop to enter the Windows Recovery Console.  Use the arrow keys to select Safe mode and press ENTER.  If windows will load in this mode, on the Start Menu, click principally made programs, click Accessories, click System Tools and run the system restore.  Choose a restore point at least 24 hours prior to the issue of logon and then proceed to the restoration.  When you are finished, Windows will restart as normal in order to check if you can now connect correctly.

    Another option if the above does not help is as follows.

    Shut down the laptop.  Tap away at f8 that you start the laptop to enter the Windows Recovery Console.  Use the arrow keys to select "Start using last good known Configuration" and press ENTER.

  • HP Pavilion computer g4-2129tx laptop: hp pavilion of g4 wifi does not

    Nice day... I reformatted my HP Pavilion g4-2129tx laptop using windows 7 64-bit OS. After formatting, I can't run the wifi, I already tried to install a bunch of different drivers for the wireless card but it is not of any wireless adapter on the network connection.

    Hello:

    See if installing software HP Connection Manager and use it to put on the wireless network adapter gets the appears.

    This package provides the connection manager HP for the notebook models and operating systems.

    File name: sp54945.exe

    If only there was missing wireless driver, you would see a device listed in the device as a network controller Manager.

    Your screenshot shows that no material existing don't need drivers, which means that the wireless card is not present at all.

    It's either because it is disabled by the connection manager software, or that he suffered a hardware failure.

    If the connection manager software is unable to activate the wireless card (or get a device network controller is displayed in Device Manager), you can assume that the wireless card has a problem.

    You can see so simply deleting and reinstalling the wireless card gets it working again.  Sometimes the connections to oxidize.  Try removing and reinstalling the card without removing the antennas.

    The antennas are sensitive and sometimes difficult to reattach.

    See Chapter 4 of the service manual for your laptop know how remove and replace the wireless card.
