I was responding to zinglebarb
But in answer to your question, yes, I even phoned up netgears technical support a long while ago, last year if memory serves, and they admitted there are issues, but v6 is no longer having the firmware developed. They emailed me an early beta firmware, and told me to roll back to that, and it did fix some of the issues but not all of them.
I recently flashed it back to the lastest firmware, hoping that perhaps the bugs had been fixed, and they haven't, hence me wanting a 3rd party firmware.
