Windows 7 Dell computer laptop connects to the router, but the internet connection is spotty/slow

I recently installed a new Comcast wireless gateway, which includes a built-in router.  My Ipod and Ipad work perfectly with this new router connection.  My Dell laptop, however, connects to the router without a problem, but it surfing the internet very slowly and sometimes can't access it at all.  The router connection remains strong during these periods of power failure, however.  I don't get online no problem when I connect directly to the router/modem with an Ethernet cable.  Network troubleshooting does not detect a problem, I have released/updated my IP address, and made sure I had updated drivers.  The issue still [persists.  Any input on what to try next?

Hello Scot,

Thanks for posting your question in the Microsoft Community forums.

The description of the problem, I see that the Internet connection is very slow on the computer.

I imagine the inconvenience that you are experiencing. We are here to help and guide you in the right direction.

Maybe there's a chance that some network settings, start services application or a third party or a security software restricted it to connect properly and is responsible for the internet connection is slow.

I suggest you to follow the steps below and see if it helps.

Method 1

I suggest you try the procedure described in the following Microsoft Article and check if it helps.

Internet Explorer is slow? 5 things to try
http://Windows.Microsoft.com/en-us/Windows/help/Internet-Explorer/slow-five-tips-to-boost-performance

Warning: Reset the Internet Explorer settings can reset security settings or privacy settings that you have added to the list of Trusted Sites. Reset the Internet Explorer settings can also reset parental control settings. We recommend that you note these sites before you use the reset Internet Explorer settings.

Method 2

If the problem persists, I suggest you to follow the steps described in the following Microsoft tutorial and see if it helps.

Wireless and wired network problems

http://Windows.Microsoft.com/en-us/Windows/network-connection-problem-help#network-problems=Windows-7&V1H=win81tab1&V2H=win7tab1&V3H=winvistatab1&v4h=winxptab1

Why is my Internet connection so slow?

http://Windows.Microsoft.com/en-us/Windows/why-Internet-connection-slow#why-Internet-connection-slow=Windows-7

Method 3

If after performing more high question method persist, try to perform the clean boot and temporarily disable security software and then check the speed of the Internet.

Step 1: Perform the clean boot

Put your system to the clean boot state helps determine if third-party applications or startup items are causing the problem. You must follow the steps in the article mentioned below to perform a clean boot.

How to perform a clean boot in Windows

http://support.Microsoft.com/kb/929135/en-us

Note: See "How to reset the computer to start normally after a boot minimum troubleshooting" to reset the computer to start as usual after a repair.

Step 2: Temporarily disable security software.

Disable the antivirus 

http://Windows.Microsoft.com/en-us/Windows7/disable-antivirus-software

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attack.

Method 4

Since then, the issue is not resolved by disabling the security software, Windows Firewall could be the next possibility. So, I suggest, temporarily, disable the Windows Firewall and check if the problem persists.

Refer to the following steps:

  1. Press the Windows key + R, type firewall.cpl , and press ENTER.
  2. Click turn Windows Firewall on or off. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  3. Click turn off (not recommended) Windows Firewall under each network location that you want to stop trying to protect, and then click OK.

Caution:

You should not turn off Windows Firewall unless you have another firewall is enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers. You must reactivate as soon as you have completed troubleshooting.

For more details, you can see the article mentioned below.

Enable or disable Windows Firewall

Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

Kind regards

    When I put the time, she can use the internet, she changes the time on the computer and returns on the internet.  What can I do?

    Not enough information.  You have provided no context.  You don't say what version of Windows you are using and you don't really describe the situation in many details.  Reading between the lines, it looks like you have a child who has time on the Internet you want to limit.  You do not tell us what tools you use to control this limit online, so it is difficult to recommend the right forum for your post.  Please update your message with a more detailed description of what is happening and what you want to do.

  • I have a Hp touchsmart 600-1050 and I also have 3 other laptops running of the internet itself, but I get a message IP address conflict.

    I have a Hp touchsmart 600-1050 and I also have 3 other laptops running of the internet itself, but I get a message IP address conflict, why? & How can I fix this problem, thanks Aldo Zapata

    An IP address conflict occurs when two computers on a LAN (local area network) or the Internet were assigned to the same IP. IP conflicts between two computers normally make one or unusable both for network operations.

    Try below methods

    1. for networks where the addresses are fixed (statically assigned) IP, ensure that each local host is configured with a unique IP address.

    2. If your computer has an address assigned dynamically, releasing and renew its IP address can bypass IP address conflicts.

    Run the following commands in the command prompt:

    ipconfig/release

    ipconfig / renew

  • Dell computer laptop starts but the screen does not light

    Hello

    I have a laptop Dell older (studio 1558) and when I used it the other day, 'static' filled monitor image and then the screen went completely black.  Now when I turn it on, it seems that the computer starts well but the screen is black.

    Get yourself an external monitor, easy solution, right? -bad.  Unfortunately when I plugged my laptop in a separate monitor, the monitor (which works fine) showed no images.

    Still, I had this laptop for a few years.  I see about being 'easy' opening and closing of the laptop.  This has been the case in recent years, however, so I don't know if something has finally given...

    I'm not the best computer savvy so sorry if I was not more detailed... any ideas, what is wrong and how do I fix?  I rather would not somewhere that make me fixed.

    You will probably get a better response if you re - post it in the forum of the laptop and mention the version of Windows, too. (This is the forum office.)

  • New Windows 7 Asus computer laptop does not connect to internet

    ASUS A52JR - X 1 laptop computer

    He'll find a network.  It doesn't let me access the network files.  It does not connect to the internet, but it's getting an IP address.  DNS does not, even if it has the IP of the router listed as a DNS server.

    I disabled IPv6 based on other peoples problems, but it doesn't seem to help.  I tried to update the driver for the CARD, but it doesn't seem to help.   I'll try update driver video, to see if it helped, but the pilot was not available on the main site (Radeon 5470) and I don't know how it would be useful anyway.

    Diagnose Windows said try restarting the router, which I did, but it did not help.  If I skip this step, said diagnosis "the default gateway is not available."

    There is also a tunnel of the card, even after disabling IPv6.  I don't know if this is normal or not.

    Any help would be appreciated.

    What router are you using? You can turn off proxy DNS? If this is not
    possible, you should be able to get the IP addresses of the DNS servers of your ISP
    and configure those statically. The use of routers IP means that the router is
    Proxy DNS. Looks like proxy DNS does not work.

  • Ethernet cable to connect my windows laptop 7 to the internet. connection is very bad. It works but only for 30 minutes max.

    My internet does not work correctly. I use an ethernet cable to connect my laptop (using windows 7) to the internet. However the connection is very bad. Sometimes it works but only for 30 minutes max, and other times it does not at all, connect saying that the cable is disconnected. I tried 3 different cables to 2 different ports, then maybe the problem comes from my laptop. It connects to the wifi networks fine but not with the cable. Does anyone have any suggestions as to what could be the problem and how can I solve this problem?

  • Windows 7 Ultimate, computer laptop Acer Aspire E15 built into the camera problem.

    I have a strange problem.

    I am running

    The laptop model is

    and first of all, as you can see - Acer only provides drivers for this model of laptop for windows 8, which is crazy because for ex I am running windows 7 on it or what do I do if I want to downgrade to windows XP, how to get drivers for my laptop?

    So my web cam driver was automatically installed with windows, BUT there is a problem.

    My camera only works with Skype and Firefox/Chrome.

    Skype recognizes it normally:

    but no other software can find and use the camera.

    webcam7 even after choosing the webcam as a source gives just a black screen:

    In addition to this, the windows software standard that normally comes with the windows called Camera - does not exist.

    The camera appears under devices.

    I tried to uninstall the driver. Install a new one. I tried everything I could find online, and nothing seems to work.

    It's almost a new laptop and it's crazy that I can't use such a common feature as the webcam.

    I'll send the same message to the customer of the Acers and see what is going, they say, but I reached a wall and do not know which can then do?

    TNX for taking the time to read this and any effort to help in the future :)

    Hello

    Please provide a detailed description of the issue with the screen shots.

    I certainly understand the inconvenience caused to you. However, I appreciate really all your efforts towards the resolution of the problem.

    In order to understand the issue more clearly, I'll ask you to provide me with the following information.

    1. You did it all hardware or software change on the computer?

    There could be a possibility that this issue would have occurred due to the damaged in the system device drivers.

    I want to provide you with the information that most Acer computers are preinstalled webcam application supplied by the manufacturer with the device. Uninstall and reinstall this application has helped many users of Acer for this problem to be solved.

    I suggest you follow the procedure recommended in the article given below for that matter Acer support.

  • Laptops give up the Internet connection intermittently

    I have a portable satellite, and my wife has a Tecra laptop. We connect through a PC to the internet via WIFI.

    Two notebooks remove the connection to the internet intermittently - to connect in the first place, we need to click on a few favorites in internet explore - only then either connects.

    I also connected through a network of friends that is configured in the same way and the same thing happens. It has a portable older tosh which connects perfectly and does not drop the line.

    We compared the settings and all seem to be the same, so something else isn't quite right.

    I'm running XP (SP2), built in the LAN card (which is fine) and connect via a netgear access point, which is about 2 feet away.
