Re: Loss of internet

Upstream power levels are too high. You need a technician to correct, call customer services and report the fault.

Re: Loss of internet

The levels are now just within limits.  But the RS errors in your earlier post are not good and could explain the dropouts you are suffering.

To check on this, set up a BQM test that will monitor the broadband feed. Let it run for a day or two and then post the result on here. It will record any problems that occur.
