browser can not connect to the internet-help!

Running A Dell 3000 desktop with XP.  After a reasonably stable relationship, my browser does not open an internet connection.  I tried IE and Firefox, neither of which work. When I try to open the browser, I get "connection to the 207.46.250.101 site." and then the browser tells me that it cannot open the web page. Operation of the fine to send and receive Outlook e-mail.

The connection is through Motorola modem and router D-Link.  My office is connected to the router which is connected to the modem.  Other home computers (wired and wireless) continue to work well on the same modem-router, set up.  Comcast tech support was not able to help.  We went through recycling, ipconfig, ping, etc.  I bypassed the router by attempting a direct connection to the modem - same result.  It seems that the router and modem are in order and the problem seems to be with the office or the software.

I tried to restore the system to an earlier time when the problem started, which did not help.  I have no restore points more early to get to the system restore.

I got the following message with attemtps have failed to get on the internet: "Windows cannot connect to the internet using HTTP, HTTPS or FTP.  This is probably caused by the settings of firewall on this computer.  Check the settings of the firewall for the HTTP port (80), HTTPS port (431) and FTP port (21). »

I have disabled the Windows Firewall.

Previously, I used zone alarm and uninstalled it, although it seems always on the list Add/Remove programs in Control Panel.  Nothing opens when I double click to open the program.  When I try to remove zonealarm, I get the following message: TrueVector Internet monitor has not been uninstalled.  Uninstall wasn't able to stop the True Vector software services, this will happen if other software uses the true vector engine.  to uninstall zonealarm mare that all other true vector programs have been closed. "I don't know what another program uses TrueVector, or if it has nothing to do with the problem.

Sorry to be verbose, but it took a lot of time and I wanted to give as much information as possible about the problem.

any suggestions?  Thank you!

    Similar to Wireless adapt. The problem is probably not the antivirus program, since I have only deinstaled and the problem persists. I've also uninstalled and reinstalled the drivers, but no solution again. I can't do a system restore point before cleaning the registry, because Windows could not find a file that is needed for the restore. I restored again since before saved registry cleaning but no help.

    Any other ideas please. This really seems teribble :(

  • Can not connect to the internet via my router

    I recently changed my dsl cable and Internet service provider. Everything worked fine when I had dsl (no problem connecting by router) but now I can only connect to the internet when the cable modem is connected directly to one of my PCs. I tried to reset the router by default and computers can see each other on the lan, but after trying to reconfigure the router with the modem cable connected it does not detect not the new address ip & dns info even if the adapter is configured to receive the ip address and dns automatically (in windows and the settings of the router.)

    Is there something else in my network installation of Windows 7 that needs to reconfigure?

    Hi Viking_Dan,

    It is really difficult to troubleshoot network connections because there are so many factors that might cause a problem. I'll do my best, however.

    Make sure that you connected the modem cable to the router using the Ethernet port on the router (Wide Area Network) "WAN". Then try to ping the router from an elevated command prompt window. The default IP address is usually something like 192.168.1.1, or similar. Check with your router's configuration. The ping command is:

    Ping xxx.xxx.xxx.xxx

    (where the x's represent the IP address)

    You will receive all 4 packets back with 0% loss. If you do not have, so I'm puzzled. If you receive all 4 packages without losses and still can't connect to the internet, then check if the radio for the router matches the capacity of your PC. Your router may have a frequency of 2.4 GHz only, only 5 GHz, or a mixture. Your PC can support one of those, or both. Check to see if they match.

    If it still does not work, try to set a static IP address for each of your PCs, with the IP address of the router as the default gateway. For the DNS server, I suggest that you use the DNS from Google free, fast and secure server. The IP address is 8.8.8.8

  • BROWSER DOES NOT CONNECT TO THE INTERNET AFTER DOWNLOADING THE REALTEK HD AUDIO DRIVER

    PC: Hewlett-Packard Pavilion Slimline model: s3307C

    Operating system: 32-bit Vista Edition Home Premium

    I wanted to update my sound driver and downloaded the Realtek HD Audio 32 bits for Vista2013 that I saw that I already had the 2009 version.  the one I downloaded is the version of the file R-271 2.11.15.0

    Can no longer use my browsers, they keep loading and after a certain number minutes, (20) and then I get a message saying that Web pages are not displayed and the option to wait or kill the pages, it's on the Chrome browser.  Internet Explorer behaves in a similar way.  My computer says I am connected to the internet.

    I called my internet provider and they had me reset the modem to factory reset, no results.

    They asked me to ping google.com, computer failed.

    I tried two restores system without result, he will not restore

    I tried to uninstall this 'thing', and the computer re-installed.

    Running out of options here, can someone please help me? or if my computer is ruined?

    Thank God I have a second, a laptop computer to ask for help on.

    Welcome to the forum.

    I don't see why the browsers do not work due to a change to the Audio.  I can imagine that the Audio does not, but I do not see the link between an update to the Audio and network failure.

    I do not recognize the patch / update installed.

    The Audio driver for your Vista system is presented as an 'Update' instead of a 'pilot', or 'original '.  You might be able to use it as a stand-alone facility - which means that the wording of the document is misleading - or the packaging may actually be dependent on the original driver that is not available on the website for Vista 32 bit OS.

    NOTES

    • To REMOVE the driver in Device Manager, you must uninstall, AND check the box to remove the driver. -Restart the system to complete the uninstallation.
    • This opens the system up to the old driver installation / original / correct, but this means that you must have something available to replace the removed driver.
    • If you use the Recovery Manager, you may not be everything first remove the existing driver - you can try just saying the system to restore the original and see if it works.  Restart the computer after installation.

    =====================================================================================

    The driver can be very well and it's the cache driver and instructions in memory which is trashed.  Power reset drain all the old instructions and forces the system to go on the drive to read the drivers and software on the computer.

    Resetting the forced feeding

    Execution of a coercive power reset or forced Reset

    Power reset cannot tell the difference between drivers - it does not analyze a driver before applying.  It assumes that all the drivers on your computer belong there.

    EXAMPLE:

    • If the driver on the disk is the wrong driver before rebooting, it's always the wrong driver after the reset.
    • If the INSTRUCTIONS of the driver are tangled, messed up, or there are missing pieces of these instructions, the reset can solve the problem.

     

    Why a power reset works to solve some problems:

    The power reset does not install anything on your computer, it does not remove the programs on your computer and Reset does not change the settings on your computer.  Your data and programs remain as they were before the reset has been applied.  Reset runs old program of the memory instructions and forces the computer go to disk operating system for new instructions.

    Why a power reset does not work:

    If the problem is more than a simple tangle, if 'good job' on the computer is not good enough - in other words, you need an update, a new driver, or there is a problem that can not be "unraveled", then reset won't work.

    If there is a hardware problem power reset will not work.

  • Computer laptop Sony Vaio can not connect to the Internet.

    Original title: Internet

    I bought a Sony Vaio laptop to my grandson. (Model UN. PCG 61611L. It is about 2 years. He can't go on the internet. It is not our internet provider so I think that

    He needs a recovery disk. Where can I buy one install?

    Hello

    Yes, I agree that you'll want to contact Sony about this. However, if the only problem with the laptop is not able to connect, then you have a recovery disk.

    The first thing we do is to ensure that you have all necessary drivers installed on the laptop. Again, this is something you can find at the Sony support site.

    http://eSupport.Sony.com/Perl/select-System.pl

    Because this laptop is not able to get online, then you will probably need to use another PC to go on the support site. Be sure to insert the appropriate for the Vaio model number and download all drivers in system on a flash drive, or other portable storage unit. Then just plug the drive into the Vaio and install these drivers.
