Disconnection every 5 minutes on average with lockstep

While on predictive mode I disconnect every hour or so on average, and when using lockstep this increases to every 5 minutes on average. I have a 50Mb download and 7 Mb upload bandwidth with my isp so I can't see it being a bandwidth issue. I did not notice this issue before the Awakening expansion. The disconnect seems like it may have a higher probability when being more active (attacking monsters) but that may be my imagination.
