High ping could be caused by:
downloads/torrents/heavy streaming on any computer/phone on your wireless/ethernet network
Bad cable(s) feeding modem/switch/hub/client
Problems/saturation on your circuit or at the provider location
If DSL: noise on phone line
If Cable: bad coax/coax connector
Things you can do to test (Windows)
Windows Key+R
type "cmd" (no quotes) and hit ENTER
type "ping /t ******.com" (no quotes) and hit ENTER (you can change ******.com out w/ regional ****** servers
here.
Change out cables and see if things improve. Also go around and turn of ANYTHING that could be connected to your network. This includes game consoles, satellite/tv/dvr box, smartphones, etc. See if the ping response "time" changes as you change things.
Also, if you know someone local w/ the same ISP as you, have them try the ping stuff and see what they get for a response time.
