Everytime I restart my computer I have to run the connection diagnostics to get access to the internet. I am running windows xp with an AT&T gateway 2 router.

Driverboost is known to cause damage and problems. In the future I recommend avoiding any programs that claim to update your drivers, boost your registry, or speed up your computer - they are all JUNK. and bad for your computer!

Access the KB971058 article via Internet Explorer (only) & run the Fix It 50202 in DEFAULT and AGGRESSIVE modes.

Diagnose Connection Problems With Internet Explorer
Internet connection and network errors can be frustrating and confusing to a casual computer user.
However, Internet Explorer provides a diagnostics tool to help identify and even repair the most common network issues.
This tool is simple to use, organized in steps, and can help get a computer back up and running quickly.

Open Internet Explorer and click on the "Tools" button in the control bar at the top of the window. From the "Tools" menu, select "Diagnose Connection Problems."
A window will appear, displaying the start page of the diagnostics tool.
Follow the instructions to determine the cause of the connection error.
The diagnostics tool will ask a series of multiple-choice questions about the connection problem you are experiencing.
Close all programs and restart the computer.
If you continue to receive an error when attempting to connect to the Internet, check that all cables and power-supply cords for the computer, modem and/or router are properly connected. Then, run the diagnostic tool again.
Call your Internet service provider's technical support phone number if you cannot resolve the error with the diagnostics tool.
The Internet Explorer diagnostics tool cannot repair or reset malfunctioning or failing hardware like modems and routers.

Internet crashing
If your Internet Explorer keeps randomly crashing (closing by itself), there may be an add-on or temporary page disrupting the connection.
Every time you browse the web, Internet Explorer keeps track of the websites you visit.
It keeps these pages, along with cookie trackers, in the "Temporary Browsing History" folder. Some websites cause Internet Explorer to crash.
Open the Internet Explorer browser. Go to "Tools > Delete Browsing History."
Hit "Delete All."
Check off the box that says "Also delete files and settings stored by add-ons."
Hit "OK."

Close and reopen the browser.
Disable Add-Ons
Go to "Start > Search."
Type "Internet Explorer" and hit "Enter."
The computer will search for any files with this label.
Double-click on the file that says "Internet Explorer (No Add-Ons)."
This will allow you to browse in IE without any additional plug-ins or add-ons that might be causing the browser to crash.
Reset Internet Explorer
Open the IE browser.
Go to "Tools > Internet Options."
Hit "Advanced." Click on "Reset" and then hit "Enter."
Close and reopen the browser.
