Painfully slow internet on Windows 7

A few months ago I bought a new computer running Vista and experienced awful internet speeds.  We have dsl and the other computers in the house all have fast internet running xp, so I was sure it was a problem with vista, much like the one described here: http://social.answers.microsoft.com/Forums/en-US/vistanetworking/thread/74f41557-4dd7-44f5-ba39-4b6009520aef

I was excited to install 7 because I was sure it would solve my slow internet issues, but...it has not.  My internet is still painfully slow, and the machines running xp are still moving at the speed of light.  This happens in both IE and Firefox, and the internet is still slow even using a different wireless adapter.  Any suggestions?

Hi RiccaDawn,
 

Welcome to Microsoft Windows 7 Answers Forum!

 

1. Did you try the steps in the thread mentioned in your post?

I would recommend you to try that method first.
try browsing internet in the Safe mode with networking. If it is a software conflict you can resolve the issue. If it still does not help you can try the workarounds I have listed below in this thread.

Method 1. Reset TCP/IP:

To reset the TCP/IP stack go to this article and either click on "Fix it for me" or follow the instructions to fix it yourself: http://support.microsoft.com/kb/299357

Method 2. Disable the DHCP Broadcast Flag:
Link: http://support.microsoft.com/default.aspx/kb/928233
Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
http://support.microsoft.com/kb/322756 (How to back up and restore the registry in Windows)
Windows 7 cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers
To resolve this issue, disable the DHCP BROADCAST flag in Windows 7. To do this, follow these steps:
1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
3. In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
4. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
5. In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.
6. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
7. In the Value data box, type 1, and then click OK.
8. Close Registry Editor.
By setting this registry key to 1, Windows 7 will first try to obtain an IP address by using the BROADCAST flag in DHCP Discover packets. If that fails, it will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.
 
Method 3. Disable IPv6:
Try uninstalling IPv6 on all interfaces, removing any IPv6 virtual adapters, and resetting the TCP/IP stack. To remove IPv6, go into the properties for each network adapter and either uncheck the box next to the protocol "Internet Protocol version 6 (TCP/IPv6), that will disable it, or select it and click uninstall, which will remove it off the computer. Then go into device manager and remove any 4to6 adapters, WUN miniport adapters, or tunnel adapters.
NOTE: You should do this for each network connection.


Hope it helps.
