slow internet

i often have to type slower while i'm on the internet because if i type too my normal speed letters/etc are missed out. i type quite fast, but i'm not that fast that my 'net' should have a problem! i currently have 10mb Virgin Media. surely i don't need higher mb to type faster?!? what can i do to solve this problem?

How does it behave if you boot to Safe Mode with Networking? If better then something is starting at boot that is causing the problem.

Advanced startup options - XP
Advanced startup options - Vista
Advanced startup options - Windows 7

Use msconfig to determine what is causing the problem

These are good tutorials on using msconfig in XP, Vista or Windows 7:
How to use msconfig in Windows XP

How to use msconfig in Windows 7

Click on Start then Run, type msconfig and press Enter.
Click on the Startup tab, record what is currently starting then click the Disable All button.
Reboot and see if it runs better.
If yes then use msconfig to enable several items at a time till you find the culprit.

If no, start msconfig and click on the Services tab.
Check the Hide All Microsoft Services box, record what is currently starting then click the Disable All button.
Again, do a regular boot, see if it runs normal.
If yes then use msconfig to enable services till you find the culprit.

Once you've found the culprit, uninstall it or find out how to eliminate it from your system. Simply disabling it in msconfig is a temporary fix at best.
Enable everything else you disabled.

like Ztruker has pointed out, the problem has nothing at all to do with your internet and it's upload/download speed, yes the problem may only show up when your on the internet and typing in a web browser, but it still has nothing to do with your internet connection speed. Ztruker will help you get to the bottom of the problem tho.
