Finally!!! I’ve had a terrible time with the Motorola SBG6580 Router / Gateway and Comcast cable service. I’ve been thinking that the issue has been Comcast, but it has turned out to be something WAY simpler… I was getting a lot of hiccups / pauses with the router. All that needs to be changed is on the Firewall, disable the IP Flood detection. I just wonder if the high speed cable is ‘flooding’ the router? I don’t know, but after turning the setting off, no more pauses!
