CM1000 Connectivity Issues with MacBook Pro

Question

When trying to connect a new MacBook Pro for my wife, it connects to router(Orbi RBS850) but it keeps throwing codes on the modem. Mind you, ALL other devices work perfectly fine including other MacBook laptops. I do not know what is going on here. Any help is welcomed.

Power levels are too high on some channels and all over the place:

&nbsp;
Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP.&nbsp;Indicates a signal issue on the ISP line up to the modem.
&nbsp;
There are come correctables and un-correctables that should be zeros as well.&nbsp;
Have the ISP check the signal and line quality UP to the modem.&nbsp;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.&nbsp;Be sure your using good quality RG6 coax cable up to the modem.&nbsp;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.https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-routerhttps://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlhttps://highspeed.tips/docsis-events/
&nbsp;
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
&nbsp;
What FW is loaded on the RBR850 router?&nbsp;
&nbsp;
If other devices are working with the system sans this one Mac Book Pro, then you should contact Apple about this device.

FW on Orbi is 4.6.14.3&nbsp;Would a knew modem fix anything or have signal checked on the incoming line first?

FURRYe38 · Answer

The ISP needs to check signal first.
&nbsp;
Also Orbi has newer FW:
