I have purchased this router for 2 of my clients (at different times) in the past year. Both have the same problem - they loose connectivity (both wired and wireless) and they also loose all their settings (SSID, etc). I re-configure them and they work from a few days to a month or more, then the same problem. I have upgraded firmware, and both are on a UPS. Both are running in a simple DHCP/router mode from a single ISP and no VPN set-up.
Should I contact support for both units to be replaced?
