I'm suffering with network spikes at home, mostly notable when gaming will jump from say 30ping to 150 for 2 seconds then slowly drop back down, every 2 minutes..
Current Home Network setup (will update tonight as this is off the top of my head at the moment) :
Router with WIFI
Port 1 2 3
Port 1 leads a cable to a gigabit switch via cat 6 cable. From this x3 cables run to My computer, xbox and my bothers computer. (all upstrairs in the house)
Port 2 Leads to a 10/100 switch that has 3 devices connected, a skybox f3 (Ground Floor)
Port 3 Leads to a NAS (ground floor) Rarely turned on.

I'm initatially thinking that its the skybox f3.
I Have tried to use wireshark but, as I've never used it before wasn't sure what was going on.
