Slow internet - Excellent Connection

Hi,

I've used my laptop absolutely fine for months on my wireless network, getting 2.3 meg a sec downloads on my 20meg connection, happy days! HOWEVER recently my laptop has decided that it doesn't want to cooperate now and after about 3 mins of booting up the connection goes from 2.3 straight down to between 40kb/s - 60kb/s. Internet pages load extremely slowly an streaming is out of the question, yet the signal strength is showing as excellent as I am sat right next to the wireless router!

I have 4 other computers on the network an they all work fine, including my desktop, i even tried using the usb adaptor in my pc on my laptop an I still get the same problem.

If this makes any sense to anyone then any kind of help would be lovely
