What is all of this in my logs?

[peterman25]

I have an RT-N66W running the 378.55 Merlin firmware. I get these reports from my wife that is working at home that our internet connection is crap. I take a gander at the logs and see a TON of what is below. Help? What does it mean? I can upload a text file if necessary with about a thousand lines of this stuff. Thanks.

It means you enabled firewall logging, which is never a good idea except for short periods of troubleshooting. You should disable that.

 

[peterman25]

Thanks. Disabled. Should I be worried about anything else? I am assuming no and that the data in the logs is unrelated to a sluggish internet connection.

Not for now, no. There's a lot of background noise on the Internet these days, so having frequent packet drops is normal. Logging them might reduce performance as the router would be working more than usual to log them all.
