  • ERROR: Windows could implement < name > (ad hoc)... error saying '"windows could not configure wifi'

    I'm not able to create an ad-hoc in my dell windows 7.

    Hey Monty,

    What version of Windows 7 are you running?

    Go in Start > run and type winver to know. You must run Windows 7 Home Premium or higher in order to create an ad hoc network. Windows 7 Starter Edition cannot act as a server/host adhoc.

    Can anyone help?

    Well, who has not responded to my problem, but it was eventually fixed by a support guy with the company who sold me the desktop PC. As I understand it, it was a problem of file sharing. Seems he had to undo sharing all my records on the desktop, then re - share once again, since when I did not have this particular problem. But it's obviously not ideal (in MS eyes at least) to the network of computers with different operating systems.

  • Airport Apple Time Capsule vs Rogers Advanced WiFi Modem Configuration

    Between the use of the advanced WiFi modem from Rogers and airport Time Capsule from Apple - a better/more strong WiFi signal will offer?

    I'm under Apple Airport time Caro as my router now (with Rogers Advanced WiFi modem mode 'bridge').    However - my WiFi connection is weak/inconsistent even after adding 1 Airport Express to extend the network.    My Modem/router are connected with a 2 foot Cat6 my ground floor, with the Airport Express on the floor to extend the reach (via WiFi - not the ethernet connection).

    When I reset my router/modem, get full power - however, after a couple days I get slower speeds.

    Any ideas how to fix?  Users are finding you work better than the other?

    Between the use of the advanced WiFi modem from Rogers and airport Time Capsule from Apple - a better/more strong WiFi signal will offer?

    Turn on the Rogers modem in router mode and launch his wifi... Plug the TC and run it in bridge, but also launch wireless audio... There is absolutely NO reason not to use both... You will often find the 2.4 ghz superior to the airport the Rogers Wireless. Apple has deliberately reduced its speed... If you need set channels wireless manual... for example of Rogers on the TC on Channel 6 and channel 11.

    5 GHz has penetration and poor range, especially when you look at the wireless signal directly above or below any router... It is of course extremely beneficial to use ethernet between the floors... Run the Rogers down and move the TC on the floor... that gives you much better signal allows you to get the most out of two wireless routers.

    Extend (Repeater) wireless using the Express will condemn you slow wireless forever. Repeaters by their nature even halve the speed of the connection... and if you place the Express in a poor signal area... getting worse. Express should be located to midway between the two... no physical distance but the power of the signal... If it gets bad signal, it will give terrible results since its own signal will be strong for customers.

    Test it... give up the Express... run ethernet to the top of the stairs and just try it with the TC to the right place.

  • Qosmio X 870 and Windows update 8.1 - secure-Boot is not configured correctly

    After update of windows 8 for windows 8.1 a watermark appeared in the dekstop who says:
    + Windows 8.1 secure Boot is not configured correctly build 9600. +

    Is something wrong with the installation of the update?

    Thank you much in advance.

    I have a Qosmio x-870.

    If you see a message "Secure startup is not configured properly" in the lower right corner of the office, this means that Secure Boot is off or has not been configured correctly on the PC.

    Secure boot can be enabled or disabled in the BIOS.
    You need to access the BIOS and should allow secure boot.
    Save the changes and restart the device.

    Your comments would be appreciated

  • SecureBoot is not configured correctly (Windows Pro 8.1 with Media Center)

    I have a HP Pavilion H8 - 1360t purchased July 2012 with Windows 7.  The system has installed UEFI and AMI BIOS v7.09.  I have upgraded to Windows 8, first preview, then the final version.  Yesterday, I upgraded to 8.1.  I now have a watermark bottom right indicating «SecureBoot is not configured correctly...» "and I get activity 2002 of the VerifyHardwareSecurity ' SecureBoot is currently disabled.  Please enable SecureBoot by the system firmware.  I have checked the BIOS and can't find an option to activate SecureBoot.

    HP an article stated that a BIOS version of 8 support SecureBoot but there is no upgrade available for this relatively new machine BIOS.

    Another article warns against upgrading an HP computer preinstalled with Windows 7 to Windows 8 with the following statement:

    " UEFI technology allows a number of improvements in the PC security and performance and is being implemented in all PC pre-installed with Windows 8.". Some PC preinstalled with Windows 7contain UEFI technology and can be modified to provide these features. However the process requires skills and specialist to complete at this time, HP provides instructions to make this change. »

    So the question for HP is: what will be a BIOS level or another solution provided for this modern computer to fully activate the SecureBoot?  I've seen a lot of posts on the forums Microsoft Community of other owners of H8 - 1360T so it's not unique to me.  As a player for Microsoft important material, it is hoped that HP would be sensitive to their customers.  As a customer of long date HP (belonging to two previous HP pavilions - the system is 3rd in the House), I sincerely hope that I have not made a mistake in my material of choice provider.

    Please download and install the update to the BIOS of your system from the following link:

    http://ftp.HP.com/pub/SoftPaq/sp61501-62000/sp61511.exe

    This will restore all the functions BIOS necessary for Windows 8/8.1. After updating the BIOS, go into the BIOS and enable the SecureBoot option. This will stop the message secureboot on Windows 8.1.

    This also enables the BIOS UEFI environment.

  • Windows 8.1 - secure boot is not configured properly

    Hello everyone. Since I installed Windows RTM 8.1, I kept making a watermark "secure startup is not configured properly" on my machine. The problem is that the secure startup option is enabled in the BIOS (and cannot be changed).

    The problem is that Windows 8 detects that it is not. Any ideas what could be the problem?

    It does not affect my work, but the watermark is very annoying.

    Thanks for the info,

  • Router not configured for port forwarding

    I use a modem wireless to my ISP, they block all ports less than 1024 and I need to forward ports 80 & 440

    How can I solve this?

    If you configure your router for a LenovoEMC Personal Cloud and always see the message, "Not configured router for port forwarding" under personal cloud Configuration, one or more of the following ports are probably blocked by your internet provider (ISP): 80, 443or port selected in the range 50500-50599 .

    Port 80 is used for internet access (HTML UN-secure) in general. If this port is blocked, but the ports 443 and 50500 are open, the Personal Cloud will work correctly even if the error message appears.

    Port 443 is used for remote access on the host network storage device. If this port is blocked, but the port selected in the range 50500 is open, you will be able to use the Personal Cloud LenovoEMC and invite others to use it, but you will not be able to access your network storage device via the Internet URL. (See answer ID 30773 for more information on access remotely through Personal Cloud LenovoEMC.)

    A port in the range of 50500-50599 must be routed through the router to use the function LenovoEMC Personal Cloud. If this port is blocked by your ISP, you will not be able to access the Personal Cloud to your network storage device or invite others to join the Personal Cloud. (For more information, see answer ID 29070 .)
