ID down to Los Angeles for the holidays and found an unsecured network to use while here. When I got home I couldn't get on the internet or my Security Center.I have a Dell Inspiron 1521 laptop and use Vista.

I can find a LAN but can't get online

I can't change my security settings

I also had a message saying that my DHCP was not put on or it did not exist.

A restore of the system should help you.

  • My iPad is not able to connect to my wi - fi network. I made an update to my router on my first laptop and I can't get an internet connecction on my iPad.

    My iPad is not able to connect to my wi - fi network.  I made an update to my router on my first laptop and I can't get an internet connecction on my iPad.  I'm invited to a password, but don't know what it is.  I'm looking for the password?

    Assuming that you have a wireless router at home that you need to know the wireless network SSID, encryption type (IE. WPA2 or WPA for example) and the encryption key and password / password.

    Many routers appear encryption key wireless to plain text. Copy in the iPad. Check the router site users manual or support to help manufacturers to enter the config pages.

    If the router does not have the key, you can also see in the properties Win 7 Wireless for your home network. Open network and sharing Center and click on Manage wireless networks left. Right click on your wireless network and select Properties. Click theSecurity tab and checkShow characters . Provide the administrator password to see the key.

  • How to stop Vista Security Center 2011 to block access to the internet

    My sons laptop has been mess up since yesterday afternoon. There McAffee Antivirus, who has never been a problem, however, "Security Center Vista 2011' at random is appeared for the first time, automatically scanned the computer and reported 25 viruses. For this reason, whenever it opens Internet Explorer to surf the net, a pop-up appears telling him that he is infected. If it it closes its doors, the internet charge only to be saying the same thing again, and if you choose to continue to sail on the same message appears, telling him that he is infected. If we go on the Vista Security Center to try to adjust the settings, it leaves us not as customization options are 'greyed out '. He asks us to buy a full version which we don't want.

    We had McAffee scan for these viruses, and it reported a Trojan horse which he deleted. I then rebooted the laptop and the computer starts downloading Vista SP1. It took about an hour to install it. I was hoping that the errors were corrected, however it is still preventing us access to Web sites, saying each site Web is "infected." Several windows pop up appears regularly telling us that the computer is infected and asked to purchase a full version of Vista Security Center 2011.

    Please help, as we have tried a lot of things, and we cannot remove this security program.

    -Simon

    Hi there, Ok vista security center 2011 is a virus. You need a better program Antimalware too to roll all this crapy virus!, I wrote this a month ago. You need too download malwarebyets you can find it here on this link http://www.malwarebytes.org/, download the free version, then you will see a desktop icon of this anti-malware program. You need also side click on it and run as administrator, then it will start up. Now DO a FULL system SCAN, not a quick analysis. It should take about 40mins or so. Now, you will see at least 4 bad Trojan and a virus. Now delete 'em, then after restart PC... Do the same thing again. After the scan is complete, and no virus found... System Restore to a point over 5 days. When we know that when the computer was working no probs then you done everything;), Post back on here to see how you are thereby. Thanks Dion.

  • does anyone know why my Security Center can't turn on the only show a message (windows Security Center cannot be started)

    does anyone know why my Security Center can't turn on showe just me a message (windows Security Center cannot be started) what can I do for this?

    If someone help me I thank a lot.

    Hi belizariocruz cruz,.

    ·         You receive an error with the message code?

    ·         What is the operating system installed on the computer?

    This problem may occur if the Security Center service is not configured to run under the Local Service account, but the dependent services are configured to run under the Local Service account.

    Note: The following can be used for Windows Vista and Windows 7.

    Method 1: To resolve this problem, make sure that the Security Center Service and all its dependencies are configured to run under the Local Service account. Set the center of security and its dependencies services to run under the Local Service account.

    a. Click Start, type services.msc and press to enter.

    b. double-click Security Center, click on tab log .

    c. Select "this account" click on the Browse button, type Local Service and click ok.

    d. type the password and confirm the password and click ok.

    Method 2: You can run the Microsoft Safety Scanner for any infection by virus. Check out the following link to do the same thing.
