1) What's the current firmware version on the DSL-3782?
2) Is there an 'always on' setting somewhere on it? A family friend has joined and their router times out after a certain period with a red 'Internet' light (It does NOT lose sync, merely the red light) I've told them NOT to turn it on and off if possible in case it confuses the DLM.

Release firmware is 1.08t but there's a newer firmware recently made available 1.10t
