hi all - quick update,
i had linksys support last friday on my computer taking over for about 75 minutes! trying to help.
After some resets, re-setup of some settings it seems to now be able to record to the SD card based on motion.
I have no luck on samba yet.
what seemed to be done is setting the recording stream to stream 2, and reducing the quality / bitrate on that stream. these were settings i missed/didnt see after the firmware upgrade and reset after.
still working on samba though
