Satellite P840 - Windows 8 - stop connection to the WiFi

Hello

My laptop has stopped to connect to my home wireless network, a week ago.

When trying to connect it says 'unable to connect to the network', or connects for a few seconds change a limited State, then falls down. (no assigned IP address) When we look at the WiFi adapter network adapters screen turns off during the disconnection then re-active.

I tried to connect to the other connections wifi with the same result.

Steps:

Reinstalled wifi drivers
Tried to use an adapter USB WiFi (same result)
removed the networking features in win 8, added again.
Updating of windows 8 back to factory default.

Can anyone suggest where this problem could be?

Hello

Like you had the same problem using the external USB WiFi dongle, I don t think that this WiFi problem is related to internal Wlan card.
I guess that the question could be related to the combination of WiFi card and router Wlan.

I recommend you to reset the settings of the router.
Reconfigure the router and don t of first set encryption. It's just for testing purposes. It would be interesting to know if it would be possible to connect to the open Wlan.

The next step: disable the TCP/IPv6 protocol in the network settings to use only the old TCP/IPv4 protocol and wireless.

Next step: update the ip address by using the command: + ipconfig / renew.
(in search, type CMD to start the console and here you can use this command)

Next step: disable the firewall and check the settings possible antivirus. Some antivirus software may affect the connectivity.

  • HP Deskjet 2540 all-in-one: printer stopped connecting to the wifi network

    Hi, my printer has suddenly stopped detecting my wireless network. When I turn on the printer, wireless blue light continues to blink and there is an exclamation point on the screen of the printer. I still have the same wifi network as before and have not changed it or its parameters. I have not physically moved the printer and the wireless works fine for all computers, iPads, and phones.

    I tried to uninstall and reinstall the HP Utility Set Up software but it couldn't detect the printer to set up.  I also tried running the diagnostic results, but all the results, said 'Not work', 'Not applicable' or 'None'. I can't even an IP address for my printer.

    My laptop can detect the printer if I turn on the wireless Direct button and I connect to this network on my laptop, but that's all. I'd rather connect the printer to the wifi so I can print from all my devices (phone, iPad etc.). The printer is less than 6 months and I do not understand what is the problem with him. Can you please specify?

    Hey @Sue1990,

    Welcome to the Forums of HP Support! I hope you enjoy your stay here.

    I understand that the all-in-one printer Deskjet 2540 does not connect to your wireless network. I can help you with that.

    To connect the printer to your network again you will need to run the USB cable from the printer to your computer Mac OS x 10.7. This makes the open Applications, Hewlett-Packard and inside this folder you will find a program with a similar name to the installation wizard. If you run this program, then you will find options to connect your printer to your wireless network.

    Please let me know how it works for you and let me know if you have any questions.

    Have a wonderful evening!

    Try disabling all security settings (WLan encryption, Mac address, filtration, hidden, etc network) on the router and restart the connection to the laptop for the WLan
    In addition, disable all security settings in Vista like firewalls and try to establish a WLan connection.

When I troubleshooted, it produces an error of "your computer seems to be configured correctly, but the device or resource (DNS server) does not. I Googled it and tried a lot of things that have been suggested - flushing the DNS, reseting the TCP/IP, etc... None of them worked.

    You have McAfee? McAfee has been updated at the same time as the last batch of updates from Windows 7 and this is the cause of problems of internet connection for most, if not all, users of McAfee.

    See the communication from this "criticism" - McAfee

    Some customers may experience a loss of network connectivity and/or errors in McAfee Security Center after a recent update

  • Satellite A500 - 03P: unable to connect to the WLan using Win 7 + event message

    Hi all

    I recently bought the Satellite A500 with the offer included Windows7 while he was available late October 09.

    So I had the Toshibe DVD for the upgrade and followed the steps and Visa home premium upgrade to Windows 7. Now I have two questions.

    (1) I get a system event Notification after start, talk to me about the system event log. The full message is below.

    Unable to connect to a windows service
    Windows could not connect to the System Event Notification service. This problem prevents limited users to logon to the system. As an administrator, you can view the system event log to see why the service failed

    (2) I was able to use this laptop for the internet before the upgrade, both via a USB wireless drive as well to the office via a DSL modem.
    Now I can't access the internet after the upgarde of Windows 7!

    For example the Optus dial-up box pop up appears commandeLorsque I click on 'connect', it does not connect.

    Can anyone help please?

    Thank you
    C I

    Hey Buddy,

    (1) did you check the Configuration of the Service for this service? The Boot System Event Notification Service type must always be set to automatic. This service is absolutely necessary for Windows and shouldn't t be disabled or set to manual startup type.
    Check it!

    (2) to be honest I never heard on the internet BEFORE, but normally, it should also be possible to access the Internet with Windows 7.
    Make sure that the WLAN or LAN card is installed properly and check the TCP/IP settings. If you are missing some driver you can get on the page of Toshiba.

    First of all, I suggest you that you also scan your laptop for infection by the virus. Second, reset TCP/IP stack Winsock settings. This could correct mistakes involving internet connectivity as a result of problems of installation of network software, due to a virus, trojan or malware infection or even due to disinfection of spyware security software.

    To repair and put back the Windows Vista

    As near as I know, your Optiplex was conducted in Australia.  If you are indeed in Australia (and you probably, if you have a modem/router of Telstra), I have no information on what products could be made available to you or where you could buy them.

    My personal preference would be an adapter that includes a cable for the antenna is not positioned between the back of your computer and the wall.  However, if your computer will be less a few meters from the router, there is not much difference, and you can use an adapter that looks like a USB key (or smaller).  My guess is that all of the products on this page might work for you--> http://www.mwave.com.au/networking-wireless/adapters-addon-cards-wireless?view=40&pricerangeid=1&filter=383%3Dusb&filteroptions=383%3Dinterface that the correct driver should be included on a CD supplied with the appliance.

  • Why windows does not connect to the Group Policy client?

    I am currently using a dell inspiron with windows 7 Edition 7720 Home premium and recently a message started to appear above my taskbar saying

    "Unable to connect to a windows service.
    Windows could not connect to the Group Policy Client service. The problem prevents standard users to log on to the system.
    As long as administrator, you can go through the system event log to see why the service failed"
    Anyone know why this is happening and how to fix it?

    The resolution is quite easy. Ignore all these tech geeks here and on other sites that just want to show how they can play with the registers - a very dangerous game.  Go to search, type in cmd, open cmd as administrator.  Type exactly this (with the indicated spaces): netsh winsock repair, and then press ENTER. You need to restart (NOT close and turn on) your computer. Bingo! Unfortunately, this condition can re - occur from time to time, as if you start your computer before you turn on your internet connection and establish a good connection.  Don't worry the fix takes about 3 to 5 minutes depending on your speed of restart computer.
