Problem with the Internet connection using IE7 and Windows Vista

Hi all

I don't know if I'm in the right forum, but I need someone, help please...

I just bought a new XPS420 with Windows Vista Home Premium and IE7 already installed.  The 2-3 days, internet worked very well.  Now, whenever I open IE7, I get a message on the connection not found or something like that.  I did some research and some forums suggest to reset IE7 using Tools/Internet Options / Advanced.  It worked... but only temporarily.   After that I turned off my computer and turned back on later in the day, open to the top of IE7, it does not work yet.  If I turn off the modem, it does not.  If I do a reset, as shown above, it would work again.

I finally called AT & T Tech support, but they could not diagnose the problem.  While we were on the phone and try to open and close IE7, and that is, I logged.  Then to test, I turned off the computer and turned it back on and of course, internet Explorer did not work.  The AT & T guy me open system information to check the properties of the network and all said that "this device works correctly.   He also suggested to disable my anti-virus program (I have preinstalled MacAfee), which I was very reluctant to do. So before you disable MacAfee, I tried IE and it worked, so I was happy.  I closed the browser and open it again and it worked; turned off the computer and turned it back and the browser did not work.  I already lost count how many times I had to do that!   When I click on diagnose the problem, I got a message on xxx.xxx.x.xx DNS. do not answer, as the server ping the remote host, but does not got a response.  On hearing this, the representative said that it must have something to do with Vista and that perhaps the OS has not been installed correctly and he suggested that I contact the place where I bought my computer and ask them to reinstall.

He also asked me to install Firefox as an alternative.  When I did, it worked.  But IE7... at the time.  I could not afford to shut down my computer once again because I was already late to work, but I guess I'll find out later. But maybe I have to use Firefox if IE does not work.  I have not really tested who. Is the thing with Firefox, it is not compatible with our applications work as well as web pages, I am trying to access (I tried one before I left) a work t look the same and difficult to navigate. And it shows "protect on" on the lower right of the browser that performs the same way, he shows up on IE.

Sorry for the long post, but I also need to evacuate.  The resolution could really be as simple as turn off the anti-virus?  But then, how to get us protected?

Help, please!  I'm so desperate for a solution.  My mother also uses this computer to access its work files.

Thank you
Remms

  • When I try to record photoshop mi account, there is a problem with the internet connection and I can't continue. How can I solve it?

    I bought a book on Photoshop CS many years ago, and once I installed it in my computer it says I should I enroll the account in order to use Photoshop (or something similar), and it also has a link to go directly to the website of the registry. The problem comes when I try to access this link given, which is an internet link.

  • I have a problem with the internet connection frequently fall.

    A strange thing that baffles me is when I go to one of the houses of my friend, my new laptop has the greatest difficulty using his wifi. My laptop has no problem using someone elses and none of the features of my friend has a problem with its wifi. Even my old laptop has no problem.

    The internet will be always connected while at my friend's House, but he often will not load pages, going very slow if it charge anything and takes some time to re-establish the connection if it does not charge not all web pages. Its wifi is normally quite fast and this are speeds very abnormal and crashes, he's never experienced. Yet once again, only my new laptop knows this. It loses connection with the router, just with the internet. You will see often Skype lose connection and may stay connected for 1 to 10 seconds before it shuts down again.

    have tried to reinstall the wireless drivers but no luck. Reset the driver does nothing. Restarting the laptop does not help. Restart the router does nothing. Removing the router of my set up and you reconnect to it does nothing. Any help with this problem would be highly appreciated!

I tried to put my desk right next to the router since I use a wireless connection, it did not work. Not even when I plugged the router it still didn't work.

    I posted a few days ago that I recently switched internet providers, and since my laptop shows or says it is connected but when I click on something, it appears in the taskbar bottom right of the screen there is no internet connection, but still it always shows an internet connection.  I have the laptop configured to use the connection with a router that is installed on my main computer. There are no other problems with any of my other devices, other phones, tablets or smartphones.  It just seems to be this laptop.  Its a Vaio Sony, bought February 2012.  I tried what was suggested last time, go into the control panel and the activation of something.  Im not a tech person, please help.

  • PIX 515E (7.0.1) - problem with the VPN connection between inside and outside

    Hello

    I ve creates a VLAN on the pix.

    In this VLAN, users are allowed to connect only to the Internet. Everything is fine, but when trying to connect with his VPN Client to their company, it has problems... (Outside traffic flow, but no traffic came back.)

    Is the only solution for this problem to create a Pool of Nat with public ip addresses, one to one mapping, or is there another solution with a public IP address (NAT on PAT) possible for this problem?

    Thanks for your replies.

    D.

    The problem is that the esp is an IP Protocol, so PAT will not work in this scenario. When the return traffic returns to pix he doesn't know how to get to the inside host. The only way to do this is by adding a static nat (1 to 1 mapping) and create a rule to allow esp. Is what type of vpn client? Microsoft vpn? Cisco vpn? If cisco VPN, perhaps, they can use NAT - T on the vpn that overcomes the question PAT by encapsulating ipsec within UDP packets. You need to talk to the admin VPN and itself it allow.

  • Problems with the internet connection. TCP/IPv6

    Hello
    For almost 3 months now this problem has occurred and must still be resolved. So I hope that someone of you can help me. I apologize if messages similar to this has already been created, I couldn't find that helped.
    Ms, I have updated in fiber optic and changed my router. Everything worked smoothly for a day. My computer is wireless as it is located far from the router. He tries to connect, but say "restricted access". My router will restart literally itself then it will repeat on and on. My internet provider told me to uncheck the box where it says Internet Protocol Version 6 TCP/IPv6. Which it works fine now. One thing I noticed, is that after this, I can't play any of my games. For example, Dota 2. Everything works fine until I'm loading to connect in a match where he finishes loading but does not join in the actual game itself. It goes the same for left 4 dead 2. NAT packets are flowing only in 1 direction... an example would be less than.... I have very little experience in this area and I hope you can help me with this because waiting for responses from technician to my router takes a long time and not going anywhere at the moment.

    Hello


    Were there any changes (hardware or software) to the computer before the show?

    Perform the check and the boot if the problem persists.

    To help resolve the error and other messages, you can start Windows XP, Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    Note: Follow step 7 to reset the computer to start as usual after the boot process.

    Hope that helps.

    The rest of my house to connect to our router fine (iphone, iPad, computer laptop) except this PC. I CAN connect to the router, but 5 minutes or later, he has a X red on the connection and said "the settings saved on this computer do not match the requirements for the network" I looked everywhere online for this, but it remains stubbornly disconnects every time.

    I tried to delete the network and try again, but he still has a red X and the message more each time. I tried to connect and Ethernet cable, still no luck. I am very desperate to solve this problem, because it's what I use for games. Can someone help me please? It would mean the world to me if someone could help me solve this problem.

    If you don't mind keeping this Ethernet cable connected, you might have a solid connection if you come to turn off the wifi connection completely and rely only on the cable.

    Here's how:

    1. Press on + R to display the run box, type ncpa.cpl , and then press OK.
    2. Right click on the wireless network connection and choose disable.

    That's all.  You can always reactivate if you wish.
