I had periodic problems with internet dropouts. Also, only 2 channels of the 4 worked on the Upstream. Cisco EPC3010
Details:
Downstream Channels
Power Level: Signal to Noise Ratio:
Channel 1: 14.4 dBmV 40.8 dB
Channel 2: 14.7 dBmV 39.6 dB
Channel 3: 13.9 dBmV 40.8 dB
Channel 4: 13.3 dBmV 39.4 dB
Upstream Channels
Power Level:
Channel 1: 54.0 dBmV
Channel 2: 52.5 dBmV
Channel 3: 0.0 dBmV
Channel 4: 0.0 dBmV
I called the cable provider and they sent me a technician. He said the problem was with my coax cables connections, replaced a few cable couplers (extension adapters), some splitters, and also modem. Now the power level is better.
Downstream Channels
Power Level: Signal to Noise Ratio:
Channel 1: 7.2 dBmV 40.8 dB
Channel 2: 7.3 dBmV 39.7 dB
Channel 3: 6.3 dBmV 40.8 dB
Channel 4: 5.9 dBmV 39.7 dB
Upstream Channels
Power Level:
Channel 1: 35.3 dBmV
Channel 2: 0.0 dBmV
Channel 3: 0.0 dBmV
Channel 4: 37.0 dBmV
But still, only 2 out of 4 channels are working in the Upstream Channels. He couldn't fix them, as I think, due to insufficient knowledge. The provider says that they only guarantees speed, not the number of modem channels. I think the problem is on their CMTS side. What causes only 2 out of 4 Upstream channels are working?
