Hi
We have been having trouble off and on for several months with the wifi/internet connection blinking on and off. So I installed Ping Plotter to see if I could pinpoint the issue.

This seems particularly problematic with the cell phones that are linked to the wifi. It eats up the cell phone batteries and causes trouble with calls as it looses the signal and then re-links. The laptops don't have as big an issue with the intermittent service most of the time.
The system will go days without a problem (last week I ran Ping Plotter for 3 days and no issues -).

I have a Zoom 5350 modem/wifi router connected to Comcast cable internet service.

This morning I caught it! It is blinking in and out a lot.

I have 5-15% packet loss in the first 3-4 hops and the last hop.

So ... Is this my router/modem?

Thanks for your help!
