CBR750 Fails after firmware update
I recently updared the firmware on my Orbi CBR750 to the latest v4.6.3.6_2.0.48 update. I can no longer establish internet connectivity. Prior to updating my connection was fine with no issues. My ISP...

Has a power OFF for 1 minute then back ON with the Orbi system been performed since last update?
You only need to press the reset button for 15 seconds then release...
Please post a copy and paste of the modems connection status page.
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.

- I did a "shock" reset w/ a netgear tech which was the 30-30-30 reset according to the case number.

- ISP on-site technician performed all these actions, and nothing is wrong on their end.
I've been in contact with NETGEAR and they're going to send a replacement device. My ISP installed a temp router so I won't be troubleshooting further. I still believe the firmware was the root cause, but I can't say why/how a firmware update would break the modem.

Ok, let us know how the RMA goes...
Avoid doing the 30-30-30 reset. Its not needed. Only a 15second press will do.
- WndrbreadAug 23, 2021GuideHey…I am going this very same issue myself. Unit is no longer covered under support…but still covered under warranty until December. What do I do?
ISP came out today…no issues on their side. RJ6 had a solid signal all the way to the box.
Offered a substitute box to hold me over, elected to come on here first (hoping to find an answer).- FURRYe38Aug 23, 2021Guru - Experienced User
