Running into similar issue as OP. Brand new router(newest version)and updated firmware worked well for about 2 weeks. Then all of the sudden it has stopped working. I can access it remotely via OVRC, ping devices on the LAN, connect to devices on the LAN, but none of the LAN devices can connect to the outside world. Contacted tech support and they suggested factory default. Defaulted router and it worked fine for 18 hours now my client is calling me and telling me there's a intermittent connection. Devices wil connect then drop offline. WTF
