Orbi CBR750 drop connection wan side

I called Spectrum, lady ran a test it showed no issue on the line. She could not see the event log since I had a Orbi modem/router she said she can only see the event log if their modem was connected.

She said she looked back the last 30 days and it showed no packet loss or other things wrong with the line.

So going to see if it goes out again I will have to switch back to the Spectrum modem and buy a router and see what happens.

The Orbi modem/router was like $550.00 a year ago and doubt it has issues or better not.

So for now going to see if it looses internet again and maybe switch back to their equipment so they can see the event log.

What a pain.

Ask them if you can send them the event log from the CBR for review. 

Old stats above in first message using a 6db attenuator

Today I got the -3db attenuator and the Downstream status is yellow.

With the 6db attenuator all status was green,

The speed is ok and to early to tell if the Event Log will give me critical messages.

I should have said to put the 2nd attenuator in line with the other one. Power levels are too high now. 

See if you get a -10dbm attenuator and try that behind the CBR. This should bring down the power to mid levels. 

Ok will try that later after the kid is done with his PS5 stuff.

Ok I put the 6 and -3 and also Spectrums old splitter 2db in line and now have power at 1.7dBmv and the downstream went from yellow to green. I also ordered a -10 just in case putting all 3 of these inline isn't good. But internet seems good.

There we go. 
Looks good now. 

If you get the -10db, then that one will be all that you need. Won't need the others in line as it would drop the power too much. Levels are good here with the two inline that you have. Your right in the middle of the spec and thats good.

Monday the -10 will be here later in the day.

I had 3 connected a -3db 6db and another splitter -3db spectrum originally installed with 1 of the outs capped off.

I got a critical and thought maybe the voltage 1.7dBmv so I took Spectrums off the -3 splitter and only have the -3db and 6db connected now and it is reading 5.0dBmv now

Ok. 

Let it run. If you continue to see issues, have the ISP check the event logs, 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.

Ok yea, most likely I will have to hook their modem up and buy a router to connect to it so they can see the logs then after they get it right switch back to the Orbi router modem. To bad they don't do a remote desktop rather then switching modems back and forth

👍

Going to be a few days. The original modem I had from Spectrum was only rated 900MBPS and I pay for Gigabit service, so the lady said they can't provision it and have to ship out a new modem.

Will update once it is in and see if they see the errors

If the ISP modem is a 1Gb or lessor modem then ya. Most speeds you'll see is around 900Mpbs on typical 1Gb modems along with a 1Gb router. Anything beyond that, you'll need a modem and router that has 2.5Gb or higher WAN and LAN ports. 

Possible that the ISP modem may or may not show same event log details. Not sure if those are standard across branded modems or not. I presume they should be.

The lady said she will be able to see critical errors and stuff with their modem. I just bought a TP-Link router good for 1.8 gigs. She said her equipment would not allow her to activate the old modem since it was not rated gigabit speed. So all set with the router matter of time when they deliver the new modem.

Well I have Spectrum Modem in connected direct to the Coax cable no attinuators between. It is running good getting 930Mbps speed and unable to see any errors or critical errors since it is their modem.

So at this point it was a lot of time and no final resolution and my Orbi sitting on a shelf now.

I appreciate the help and did learn something.

If I get any drops in service I will respond down the road, but for now just going to be Idle.

What brand model# modem are you using? 

Could use the TP Link router as a router, disable it's wifi radios and then configure the CBR for faux AP mode and connect it to the TP Link router using one of the CBRs LAN ports. Then connect up any RBS to the CBR. 

Otherwise, ya, let it run. 

The router I just bought is a TP Link AX1800

I can only access and login to the TP Link.

The Spectrum modem I do not think there is a way to login to that.

Ya modems do have web pages. 

Just a suggestion if you wanted to continue to use the CBR system for wireless abilities. 

What is the CBR system? Bad with abbreviations. Is that the Orbi?

Yes.

I had already tried using the Orbi Modem/Router with the Spectrum Modem and it did not seem to work.

That is why I bought the TP Link

For the faux AP mode on the CBR, you'll need the TP Link router. 

Ok thanks. Might try it but don't need it. I wish Spectrum would of just let me send the log I had on the Orbi on critical errors it would of made things so much easier.

Should send it anyways. Seems like the Event logs read out would be same as other branded modems since the modem side is all DOCSIS information and diagnostics. 

Maybe at some point put the CBR back ON and check it. Other wise, good luck.
