What could cause this?

in Connectivity May 25, 2019

I have always had problems with internet connection, but recently it's getting unbearable. 

On a good day I'll get a connection that will last a few hours before requiring a reboot, and on the worst days it's so slow its unusable, even if the connection holds at all. Which more often than not it doesn't.

 

I recently called spectrum hoping to get a technician to look into this problem but I get a canned response that this is normal and it's being taken care of, which I doubt because its been like this for months.

 

I've done everything on my end to resolve this; from purchasing a new modem, to running a new length of RG6 coax cable straight from the ground to the modem. And yet the problem persists. No I don't have any splitters or filters on my end, its a straight run to the CM700 modem and the cable is brand new.

 

Here is how the connection looks after about a day of use (it crashed and power cycled early in the morning):

Bear in mind this is on a good day where its working as well as it probably ever will.

Can anyone help?

    WOW... those are some scary signal levels. Surprised you actually captured that upstream power level... modem's usually reboot before they climb that high.

    This is NOT a "normal" signal page. If whoever you are on the phone with does not see the problems there... you need to speak to someone else.

    If they haven't recently done so, someone needs to come on site and check things out. If it isn't within your home, it is something outside, up on the pole, or somewhere further up/down the lines in your neighborhood.

    Signal levels are too low, and what is there has too much noise in the line.

    Modems are rarely the cause of connection issues. If you bought the new modem recently I would return it and save your money. 

     

    These signals are definitely not normal...this is pretty much a textbook case of extremely poor signals. Keep calling for a tech visit. The rep that told you these signals are "normal" should be sent for re-training immediately. If the in-home tech finds that all is good from your modem back to the street/alley/pedestal...then they would need to initiate a ticket for another crew to check the main lines.

    Another issue that RickE alluded to is that you only have 22 working and bonded DS channels.  Virtually every CMTS server in Charter's system is programmed to assign DS channels in blocks of 8 at a time, so you should have 8, 16, or 24 if the cable plant and your modem are both working properly. 

    The combination of very high error couints on so many of your DS channels AND seeing only a single uplink at over +56 dBmV tells me that the distribution trunk cable is mechanically damaged.  If you've recently had high winds bringing tree branches down (most of the country this winter!), the line maintenance crews have some serious troubleshooting and repair work to do before Spectrum can deliver clean internet running at rated speeds up and down. 

    Last, if you are paying for a Gigabit connection, despite what the modem manufacturers have printed on their retail packaging, Spectrum has not yet certified ANY Gigabit modems for customer purchase and installation at this time. Use only the modem which they provide (at no extra charge) for a Gigabit connection.
