Orbi CBR750 downstream LED is off
Hi all,
I just came back from a 2 week trip and noticed that the Orbi CBR750 LED is constantly off. The modem seems to be working but slow. I saw the followings in the event log. Any idea what's going on?
Warning(5) | MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1 |
| Notice(6) | TLV-11 - unrecognized OID |
| Warning(5) | REG-RSP-MP Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value |
| Warning(5) | RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW |
Thanks,
Wayne

Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.It's running the latest firmware V4.6.14.4. Attached is the cable connection information. Looks like downstream isn't locked.
Power levels are on the low side but with in spec. Could maybe up the power just a bit.

Correctables and Un-correctables are zeros so thats good.
Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.
