This is a public, national forum so unless you say what state/area you are in, you probably won't get much help. Also, there are only 5-10 regular posters in the internet forum so it isn't very useful for trending data.
Did you want to troubleshoot the issue? If so, what model modem or gateway do you have? What light(s) are on it? Is it just effecting internet or TV too? If you login into Cox.net do you see any outage notification?
