High ping to whole internet
We've been experiencing high latency in games and get 400+ ms pings even to google.com, 18.104.22.168, etc. Modem upstream and downstream power levels are good, and so is S/N ratio. Modem logs are clean. Ping to my modem is 1ms or less so it's not my network. The connection is hard wired.
What could be going on?
