Packet loss recently started and has been persistent
I've had Spectrum for years with no problems gaming. But starting about a week ago (I can't remember exactly what day), I've been experiencing intermittent packet loss, which has impacted online gaming (League of Legends).
It's not constant, but it happens 10 or 12 times an hour, and regularly enough to impact most games.
After the problem started, I've been pinging google.com to watch for packet loss, and it happens for Google at the same time as League.
I don't know what the next steps are to troubleshoot this.
