Orbi CBR750 random outages
Not consistent but at random times I'm losing internet connection. The connection does NOT drop on the modem/router though, it still shows the status up. ISP has come out multiple times (4th was today). These "blips" as I'm calling them were happening every 5 minutes, almost exactly. They came out, changed the hardware on the line, left. Still happening. Came back again, said they see errors on the line from the street level connection and schedule an appointment with the street level tech.
Street level tech says they monitored connection for an hour and see no issues, recommended a replacement line from house box ISP connection to inside of house. They do that today and yet the issue persists.. just differently. Instead of every 5 minutes for only 5 seconds, its once an hour for 2-3 minutes.
Of the repeated errors on the event log, these seem to happen the most:
Mar 03 2023 14:56:15Warning (5)DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value
Mar 03 2023 14:56:15Warning (5)RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW

Re: Orbi CBR750 random outages
Does the front LED turn PINK or any of the modem UP or Down LEDs give an AMBER light?
What Firmware version is currently loaded?
Please post a copy and paste of the modems connection status and event log 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.
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.

Re: Orbi CBR750 random outages
A lot of this info was already in my post but i'll post it again.. No there is no color on the orbi. Status lights show up.
The firmware is current, there are no updates available.
Techs have checked the line and it says fine both inside and at the street level box.
Yes there is a splitter, the line splits between my cable box and my modem router.
The line and the splitter are brand new as of today.
The modem has been powered on/off many many times and cycled many many times.
I cannot paste the log currently. It does this sometimes where the log appears blank and will show up later. The errors in my original post are the same errors that show up around the downtime.

Re: Orbi CBR750 random outages
Please copy and paste the event log into a word doc then save off as a PDF then use the Choose File button on your next post to attach it.
Who is your ISP?
I see power levels are all over the place and mostly on the low side thought with in spec, channel 32 is -9db and is just too low:
https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router
I recommend removing the splitter temporarily to see if the power comes up and the Correctables and Un-Correctables can get to all zeros.

Re: Orbi CBR750 random outages
I can't even view the event log. Its blank, eventually it updates, but sometimes it takes awhile. I dunno *shrug*
ISP is cox. The problem with removing the splitter is it removes the ability to access the cable tv, we only have the 1 cable for both internet and tv. I will give that a try later tonight though once the children are in bed and won't be upset about TV being gone.

Re: Orbi CBR750 random outages
Is the FW version v.4 on the CBR?
How was the FW updated on the CBR? Via Orbi app or CBRs web page using a wired PC and web browser?
Is Armor, SPC or Traffic Meter enabled on the CBR?
Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.
Factory reset the Orbi router and power it off for one minute. Then power ON the Orbi router and walk thru the setup wizard again using a wired PC and a web browser.
Press the back reset button for 15 seconds then release.

Re: Orbi CBR750 random outages
Firmware is V4.6.14.4_2.3.12
I'll look into doing a factory reset. If not, the tech will be back tomorrow late afternoon to try with an ISP router to see if we can duplicate it with ISP provided.

Re: Orbi CBR750 random outages
And then there are times like this where this happens, the internet doesn't FULLY go down but upload tanks:

Parental controls on, but not the others.

Re: Orbi CBR750 random outages
Also slightly confused with this statement
"I would power OFF the ISP modem for 1 minute. Factory reset the Orbi router and power it off. Power ON the ISP modem and let it sync. Then power ON the Orbi router and walk thru the setup wizard again using a wired PC and a web browser.
Press the back reset button for 15 seconds then release. "
CBR750 is a router/modem combo so no ISP modem.

Re: Orbi CBR750 random outages
Disregard the ISP Modem statement. I forgot to take that out.
Lets do a factory reset on the CBR and setup from scratch. Lets avoid enabled SPC.
Use a wired PC with Ooklas installable speed test app to test speeds right after the CBR is setup.
How was the FW updated on the CBR? Via Orbi app or CBRs web page using a wired PC and web browser?

Re: Orbi CBR750 random outages
Looks like connected directly to wall plug (no splitter) produced same result of errors that seem to keep happening. Awaiting uptime on factory reset before confirming that side of things too.

Re: Orbi CBR750 random outages
The problem is, ISP sees no issue on their end, both at the house and at the street level box. Last night hit a new low of only .01 upload speed.
Tech is coming out in the next hour to re-test the line, and then give us an ISP provided modem to see if Orbi is the issue so they know how to proceed next.

Re: Orbi CBR750 random outages
Sounds good, using one of there modems would be telling. I would have the tech put there modem on first before he makes any changes. Test the modem. I presume this will be a gateway modem...

Re: Orbi CBR750 random outages
I'm at a complete loss. Tech replaced line from outdoor box to house. Still getting intermittant upload of point 1.
He says that if we continue to have issues, there must be something interfering with our wifi signal. And, since my orbi is 2 years 1m old, i don't think there's any sort of help from Netgear on this coverage either.

Re: Orbi CBR750 random outages
0 correctables, and 0 logs since setting up new one. That's disappointing that this router only lasted 25 months.
