DA laggy?

Maybe the router is giving the ICMP ECHO message a very low priority or tossing out any overlapping requests to help reduce the impact of a DoS attack using that message.

Looks like you were right skuzzy. I disabled the DoS attack protection thing, and voila!.


I guess my question at this point would be, is there any security reason on why I should keep it enabled? I'm fairly computer savvy, router is properly setup with a secure password, wireless is completely turned off etc.,

Disabling the "ICMP ECHO" response is a good thing.  It will not stop a flood of those requests, but it will stop an answer from being generated, which will double the overhead of the router and cause it to succumb to a DoS attack faster.

This is a screen shot of my router config screen, and I think it's similar to what you are referring to. Does this look correct to you?

Personally, I would not allow the router to respond to a ping.  Just turn it on when you need to.

Thank you Skuzzy, wasn't sure if that was what was causing my weird ping plotter results or not.

Ok We've found something interesting.
The lag only occurs at 5pm-12am GMT weekdays and 10am-12am GMT weekends, which leads me to believe that it is traffic management at peak times on the ISP's end.  However that still doesn't address the fact that only the DA is affected.

weird..
