Apparent file system problem exhibited in syslog:
Nov 6 21:05:07 miniupnpd[700]: could not open lease file: /var/lib/misc/upnp.leases
Nov 6 21:05:09 miniupnpd[704]: could not open lease file: /var/lib/misc/upnp.leases
I don't recall ever seeing the above issue on .9135 stock on my RT-AC3200. I had 2 devices lose internet connection concurrent to the above messages. Router reboot solved the issue, but the error does point to some upnp filesystem-related issue.
