We were getting 30s-5m drops in connectivity at intervals between 5m-10h, conditions that were hard to reproduce. I began using Ping Plotter to help diagnose the issue. We continued to have the problem, however, I could always see a connection to the router (gateway).
I called Comcast and the technical support person insisted that "it is your router" and that "I am looking at the history on your modem and you have never lost connectivity, except when it has rebooted."
At the time we had the a A2 rev of the EBR-2310 wired router which was about a year old. I had my wife go to Best Buy and get a brand new EBR-2310 which is a rev B.
I configured the router the same as the old one, however, now when I crank up the ping frequency on the Ping Plotter sfotware to ping once a second, I loose connectivity a LOT more.
The log shows dropped packets:

This seems to be because the router cannot establish more "sessions"? (connections?)
It seems to me that the router is establishing a session for each ICMP ping.

The previous rev A2 of the EBR did not drop like this when I pinged frequently.
Is the hardware defective? Is there a setting I can change to get the rev B to work like the rev A2?
