Upstream bonding issues

I've been struggling to get 4 channels bonded on my upstream. 

Any ideas? It's a Netgear C6300.

 

Upstream Bonded Channels
Channel | Lock Status | US Channel Type | Channel ID | Symbol Rate | Frequency | Power
1 Locked ATDMA   2 5120 Ksym/sec 24200000 Hz 54.8 dBmV
2 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV
3 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV
4 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV

Re: Upstream bonding issues

you have a coaxial issue... get rid of all the extra splitters, open ports. Modem must be on no  or the first 2 way if you have cable boxes

Not a modem issue, is your wiring.

If nothing obvious call TWCmaybe outside line issues

This is how my current downstream appears. Does this seem ok?

I don't have anything else in my home plugged in, no splitters, etc.

Bonding takes place in the modem, not in the router.  Your DS signal levels are very low for having no splitters in the line.  The modem's upstream signal is not being heard at the node to which your are supposedly connected. That's why you have only one US channel and it is transmitting at above +52 dBmV, which is VERY BAD for your entire neighborhood.

A modem connected directly to the drop line from the street should normally be receiving signals in the 0 to +6 dBmV range unless the line is very long or is old and degraded.  Typically the line is full of water because critters or branches have chewed through the insulation.

Re: Upstream bonding issues

this could be corrosion, a water filled internet only trap or tap off block on the pole. You need TWC out. They need to replace connectors and the grounding block for a start.

 The single US channel at 55 dB is out of spec and is red flagged and grounds to get a tech out.

Re: Upstream bonding issues

Thank you karlbeckman for your advice. 

Are my downstream signals fine? If I call TWC/Spectrum what do I tell them in order to get a tech out here?

Re: Upstream bonding issues

they are in spec but not "fine" You need twc out to fix both issues.

There is a problem between the modem and pole.

 Call twc/spectrum

"Intermittent connectivity due to  US partial service errors."

Re: Upstream bonding issues

Well I just purchased a new modem (surfboard  6190 + Asus RT-AC68U) and threw my C6300 in the garbage.

 

After activating, I'm getting 24 bonded downstream (woo) and still only 1 upstream that constantly looks like this (sometimes says 56bBmV).

ChannelLock StatusUS Channel TypeChannel IDSymbol RateFrequencyPower
1LockedATDMA25120 kSym/s24.20 MHz

54.75 dBmV

 

If I contact support, what do I say? Because I know they will give me the rundown of testing, and what type of tech do I need out here to take a look?

We told you the issue was not your previous C6300 modem, it is a cable signal problem.  You will not fix a cable defect by swapping the modem.  You need to have TWC come out and fix the defective cable. 

Do exactly what MsRaye told you yesterday:

Call twc/spectrum.

Tell them you have "Intermittent connectivity due to  US partial service errors."

 

If they ask why you think that, tell them "I only have one upstream channel and the modem says the signal level is +55 dBmV."

They will read their complaint script and want to reset your modem and 'send it new code.'  That is when you tell them  "A remote reset of my modem does NOT clear the problem, I already did that.  Send a service tech out here!"

Re: Upstream bonding issues

I wanted to get rid of the c6300 regardless. I wasn't a fan of it and i was having hardware issues with the wireless anyway. 

 

I guess I'll try out my patience. Talking to these support people is a pain.

 

I did find out that in another room I had a coax with a splitter attached to it, attached to the wall, but not attached to any devices. I completely removed the cable and I'm now looking like:
