Why does my wireless internet disconnect when I try to download something?

[Guest]

Hello,
My wireless internet works fine if Iam just looking stuff up, reading e-mails or on e-bay etc but as soon as I try to download something, this time it was google earth, or watch something on you tube etc it just keeps disconnecting. Really annoying!

What kind of laptop do you have (brand)? It could be the signs of a the wireless card going out or it could just need a driver update.
