Sometimes when I download near my ADSL connection's full speed the connection becomes more and more lagged even though the download speed is constant. Eg. a ping to a close server might be 60-120 m/s when downloading at full speed but overtime the ping will rise to 600 m/s making my VOIP unusable. I know there is QOS but that doesn't seem to help and my issue seems to be with the Linksys itself being overloaded. I've seen this behaviour with two different WRT54G models with the Linksys factory firmware. Especially with torrenting I find these routers can't handle the traffic without getting extremely lagged. Does anyone know what the problem is and how to fix it?
