Moved channels?
Hi,
My internet went down last night at about 00:26 this morning, and came back on about 2 hours later. I checked this evening to see what had changed. My host name remained the same, except my channels have changed.
Before they were 97, 97, 98 and 99. Now they are:
Locked QAM256 106 55616000 Kbits/sec 307000000 Hz 4.0 dBmV 41.6 dB Hybrid
Locked QAM256 105 55616000 Kbits/sec 299000000 Hz 4.2 dBmV 42.0 dB Hybrid
Locked QAM256 107 55616000 Kbits/sec 315000000 Hz 3.4 dBmV 41.4 dB Hybrid
Locked QAM256 108 55616000 Kbits/sec 323000000 Hz 2.6 dBmV 41.2 dB Hybrid
My upstream remained the same, except the power level dropping by 1dBmV.
Event log showed the following:

Now most of you are probably going to say, it's working, leave it. I just want to know why channels have changed.
Danke.
