As you stated, it worked perfectly for 3-4 weeks and then you received the “failed to enqueue” message.
Obviously, something is out of sync. Since you have already restarted your Cambridge 851N, I suggest you turn OFF your router and modem (remove battery, if used) for 2 minutes and try again.
I am ’guessing’ that maybe your Cambridge 851N unit is ’out of sync’ with the router and modem. I am hoping that by turning off the router and modem will solve the issue. In other words, this will reset the connection between the units. Please keep me posted.
