Good news to report. After an initial hiccup the night after install, firmware has been stable a week later. Looks like they fixed whatever was causing the crashes with this version.There is something flakey with the last two updates every since the ddns started reporting on the hour that the ip hasn't changed. Random claims of lost wan then a crash. It recovers most of the time on it's own but sometimes I have to turn the ddns off and back on manually to get it working again. I'm considering reverting to an old version as well.
V1 hardware.
