I'm pretty new to Ubuntu to please bare with me...

I've just joined the dark side, moving over from Windows 7 to Ubuntu 12.04 (64bit) and I've found that the Internet speed is excessively slower then in Windows (dual booting) I've tried this with Ubuntu 32bit and 64 bit and still the same.

It's possibly a driver/firmware problem but when I've been searching online I've not found any additional files. When I boot into Ubuntu it already has a built in driver that it used (luckily) but is there any way I can speed it up? It's painfully slow...
