... Really? Are you serious? I never would have guessed that.
In case you hadn't noticed, I was being overly sarcastic. Any savvy net user knows that Wi-Fi is completely unreliable. I still connect my Xbox 360 up with a good old fashioned Ethernet cable for fear of being disconnected whilst pwning noobs on Black Ops (or more realistically, being owned by 7 year olds).

Anyway, the astoundingly intuitive and obviously otherwise unobserved results yielded by the report by Epitiro states that home users experience up to a 30% loss in browsing speeds with applications such as Skype being particularly affected.

You can read the Wi-fi performance report here, or check out coverage of the report on the BBC.
