Hi there,

+1 ! 50mb Virgin, fine download speeds, regular loss of packets or something going on interupting gaming.

Yep Ive been having the same issue for weeks. I've raged complained, accused housemates of sercretly downloading terrabytes of pron and so on and so on.

I've fiddled with MTU's reset back to defaults, Applied and removed QoS, tried ethernet, the list goes on.

One recent lead i have come across came about when running netanlyzer (http://netalyzr.icsi.berkeley.edu/) a nice bit of kit. Anyway I got this report

"Network buffer measurements (?): Uplink 1300 ms, Downlink 74 ms
We estimate your uplink as having 1300 msec of buffering. This is quite high, and you may experience substantial disruption to your network performance when performing interactive tasks such as web-surfing while simultaneously conducting large uploads. With such a buffer, real-time applications such as games or audio chat can work quite poorly when conducting large uploads at the same time.
We estimate your downlink as having 74 msec of buffering. This level may serve well for maximizing speed while minimizing the impact of large transfers on other traffic"

I am lead to believe this large uplink buffer is controlled by Virgin and could be the cause of these jitters, When i started searching for methods of reducing this uplink buffer (to no avail) I found people experiencing a similiar issue to myself in online gaming.

I am no techie, minimal knowledge. But does this sound appropriate?
