I was having a tremendous amount of problems with this on my router. As a last resort I did a factory reset on the unit and put my settings back in manually and it's been up for weeks now with no disconnects.
When I first purchased this router everything was working great and then a new firmware was release (1.04 I believe) so I updated the firmware and then after that was completed I uploaded my old settings and then bang it started to crash over and over. I've had this same result with all subsequent releases of the firmware and each time I upload my old configuration file the router would inexplicably crash after a certain amount of time (it varied).
It's a real pain to have to go in and manually make every change one by one, especially with the number of reboots it wants to do after some of the changes.
As an FYI I also had this happen after making a configuration change and right after the restart it began to crash again, once again I needed to go in factory reset and manually pump in all the settings including the Enable WAN Ping Response change and it was fine
Since updating the Firmware to 1.10 I have not needed to make any changes so I don't know if this issue still exists for me or not and I have no plans to test it
