hi mathew,  i use a wired connection, no other device connected to router (wired or wireless) altho to be fair most of sunday and today its been ok . no packet loss ,ping 17ms jitter 1ms. but it seems to be an intermittant fault with evenings being the worse. have tried rebooting the hub one , rebooting the xbox , changing ethernet and hdmi cables, shouting at the wife and changing dns values on the xbox. just hope its ok now
