My SB8200 and SB6183 only get one upstream locked channel at 35.6Mhz. I see many posters have 4 locked upstream channels. How have other folks resolved this issue?
| Channel ID | Lock Status | US Channel Type | Frequency | Width | Power |
| 4 | Locked | SC-QAM | 35600000 Hz | 6400000 | 38.3 dBmV |
Also the SB8200 on power-cycle takes 18 minutes to lock the upstream channel. The upstream channel tests 16.4, 22.8, 29.2 at different send power levels, till it reaches 35.6 and acquires lock. Has anybody else faced this problem.
Power cycle timestamps are mm:ss.
- 01:00: WebUI comes up in 192.168.100.1
- 01:25: Receive LED steady green, send LED flashing green.
- 01:25: Downstream channel locked 49.5Mhz, 13 dBmV, 44dB SNR.
- 01:25: Upstream parameters acquired.
- 01:26: Upstream channel 22.8Mhz, 48.8 dBmV.
- 05:25: Upstream power oscillates like th 59, 49, 38, 28, 61, 51, 46, 41, 31, 64 dBmV.
- 12:11: Upstream channel 29.2Mhz
- 14:08: Upstream channel 29.2Mhz 56.5 dBmV.
- 16:39: Upstream channel 29.2Mhz 36.0dBmV.
- 20:00: Upstream channel locked 35.6Mhz 38.3dBmV.
- 20:00: All four LED lit and steady. Blue receive (docsis 3.1), green send (docsis 3.0), green Internet.
- 20:00: 4 upstream channels decrease to one.
