word of advice, change your ISP. Tiscali were terrible when i was with them their 'unlimited' was crap they just switched my internet off in peak times. Switch to someone else fast
Some of your guy's speeds are ridiculous. My cheap Dad doesn't want to spend much on internet so mine's pretty slow.
This is with my parents in the other room streaming Netflix on an HD TV so it may be slightly faster than this but I don't know if that would affect this.
It also seems my room has a black hole it in because I mysteriously lose signal and then it's back all the time while a room over the signal is much faster and more reliable. Maybe it's my craptastic machine....
