Dynamic Range Window Violations and loss of connection
Recently I've been dealing with excessive DRW violations and loss of connection. Not sure if it's a coincidence or not but the local fiber company has been running fiber up the poles through the street all week, not sure if they knocked a connection loose up the line but yesterday and today I've been dropping connection multiple times. I noticed the upstream power levels on my modem are lower than the recommended values by Arris. Anyone care to chime in on these power levels? Thanks!
