Ryan....you are completely right in what you are saying - I understand where you are coming from.....274kb/s from SpeedTest.net is appauling especially on a supposed 4Mb line!!

Sounds to me like there is definately something amiss on one/both of your computers, could be virus or spyware related or, someone else using your connection to be honest!!!

Have you tried to connect to the internet with either just the laptop or just the computer switched on? I'd be inclined to turn off the wireless & the computer & connect to the HomeHub to your laptop via an ethernet cable because you actually have some kind of security on there. I'd get rid of PcCillin & install AVG & do a spyware scan using Ad-Aware then see how you fare!!! Also give the homehub a cold reboot - power off - wait 10secs then back on again!!!
