For about 2 months now I have been experiencing lag across every game I play on XBL, mainly SF4 and Halo 4.
I have tested my internet speed multiple times, always resulting in around 30mb download and 2mb upload and very low ping averaging around 15, which apparently is a decent connection.
Other pcs and gaming consoles in my household experience no lag at all which is strange as they use a wireless connection and recieve a better connection then my wired 360.
I have scoured the internet in search of answers but I cannot find anyone with a similar problem, which has lead me here.
I have a Virgin Media Superhub if that helps at all.
