I've just got a new Vaio FW31 & the Wifi is incredibly fast when downloading zip files. So much so, that it seems I have a problem with my other laptop, which is a Vaio AR11b. I downloaded the same zip file to both PC's & the dl speed on my new pc was 16 megs per second, but on my older pc it was only 6! Does anyone know of a way of troubleshooting the connection speeds? I can't find a difference between setups on the different pc's.
