You may want to try resetting the Winsock Catalog as well as the TCP/IP Stack, try this;
To reset Winsock for Windows Vista, follow these steps:
Click the start orb, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.
Type netsh winsock reset at the command prompt, and then press ENTER.
Note If the command is typed incorrectly, you will receive an error message. Type the command again. When the command is completed successfully, a confirmation appears, followed by a new command prompt. Then, go to step 3.
Type exit, and then press ENTER.

The reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually:
Click the start orb, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.
At the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt
Note If you do not want to specify a directory path for the log file, use the following command:
netsh int ip reset resetlog.txt
Reboot the computer.
When you run the reset command, it rewrites two registry keys that are used by TCP/IP. This has the same result as removing and reinstalling the protocol.

Yes that would probably be a good next step.Link RemovedI also have McAfee AV. I see many people uninstalling this and having some success. Should I give that a try?
Yes that would probably be a good next step.
Use the Programs and Features Applet in the control panel to uninstall it and then follow up by using this vendor specific proprietary removal tool from here Link Removed to remove any remnants.
Replace for now at least with MSE from here Link Removed due to 404 Error and see how it goes.
Hello MnMFTW,
Go back in to "Change adapter settings" (Control Panel\Network and Internet\Network and Sharing Center)
In the "Properties" dialog box, select IPv4 then Properties, at the bottom, select, "Use the following DNS server addresses"
In the Preferred box, place, 208.67.222.222
In the Alternate box, place, 208.67.220.220
These are from Open DNS
I would also suggest leaving IPv6 enabled.
Hope this helps
Don
There are some basic fundamental reasons to leave IPv6 enabled as some of the components within Windows 7 rely on IPv6 to function properly or at all.Hi Don,
I just wanted to know that why should we leave IPV6 enabled?
Also what does it mean by Open DNS?
Thanks
OK, keep us posted.
If that doesn't help alleviate the problem, the only other thing I would suspect is that perhaps a recent round of Updates via the Windows Update Utility, might have included a driver update for your network adapter so you can try to roll that back and see if that helps.
Open Device Manager, expand Network adapters, select then right click the problem adapter and choose properties.
Select the Driver tab from the top tab menu and see if the button labeled "Roll Back Driver" is available, if so go ahead and roll it back and see what happens.
Personally I would leave McAfee off the machine. MSE is fine for the most part combined with the Native Windows 7 firewall.
I augment it by running Malwarebytes Pro just for the extra peace of mind.
As far as the sluggish network. Make sure you go back and set your IPv4 properties in the properties of your network adapter to obtain automatically in both instances.
I'm personally wondering how many of these instances of networking issues that we've been seeing lately that seemed to be related to DNS resolution might be caused by either McAfee or another over zealous security suite, perhaps coupled with some recent security update from Microsoft.
Thank you for sticking with the problem and finding the resolution and for posting back and updating your thread with that information.
Hope to continue to see you around the forum.

Randy
