Only 3 Downstream Channels. Used to get more. Also a Power Difference. What changed?

This is this year vs last year.  What did Spectrum change?  How do I get it fixed?

 

This is what I currently have...Signas.jpg This is what I had a year ago (per a post I made here):

Re: Only 3 Downstream Channels. Used to get more. Also a Power Difference. What changed?

Since no one else has commented I will take a stab at it.  You have real problems here. You should have 8 downstream channels. Your signals downstream should all be about the same level. What is weird about this is while your downstream channels have changed dramatically since your last readings your upstream are about the same. This makes me think it might not be the standard problem of a cableing issue but something more serious. That being said I do recommend you check all your cables. No open splitters, bad cables, bad connectors, etc..

 

You will probably need to have a tech out to check their equipment. Also your modem might be going bad.  Do a modem reset and see if things get better. If you have a high speed plan this must be effecting your speeds. You will want to get this looked at.

Looking at your modem connection here through our system we definitely 

do need to get a technician out. I am seeing 2 missing upstreams and bad

levels on RX and SNR. 

 

I encourage you to contact support directly to get something scheduled.

Agreed. You have serious issues, probably coax related. A tech definitely needs to come out and check the wiring for loose or corroded connectors, water-logged access boxes at the street or alley if underground, damaged cable in overhead lines, etc. You can check for these items in areas you have access, like from the drop to your house to the modem.

 

Do you know if your neighbors are having similar issues? Could be a bad amp feeding the entire street.
