Re: Internet Consistently Dropping From 30Mbs to 0.5Mbs

Thanks for all of the help with this issue! There were no 4G  repeaters in the area that I could see and the tech insisted that the signal levels were in spec. I showed him these messages and he was kid enough to run a new cable from the junction box into the house. Now with the new line, things seem to be back to normal for now, i'll post back if anything changes in the next couple of days.

 

Here are the new signal levels (there is some overdrive but it isn't affecting things at the moment)

You are correct that DS levels are far too high.  They should be between -8 and +8 dBmV, ideally around 0 dBmV.  DOCSIS modems don't decode much at all with levels above +15.  The tech needs to return, measure the DS level again, and dial it down by about 10 dB.

Post the upstream please.

Your level shouldn't of gone up 24 dB..

Let's see if the US went way down.. If so the tap off block is defective

Here you are, the tech said as long as my speeds were ok, then the over run/flow is ok..... Smiley Embarassed

Re: Internet Consistently Dropping From 30Mbs to 0.5Mbs

Ok, upstream dropped by 6 dB from the earlier post

 You really need twc to fix the levels out at the tap, I wouldn't settle for a 10 dB pad . It would put the levels in optimum range but I'm worried that the amplifier out on the street has gone wide open and when it's replaced, the pad would drop your levels too much.

You need TWC to get the bucket truck guys out to fix the tap/ amplifiers.

An in house tech cannot properly correct the stuff that's bad out on the street.

HOLY SCHNIKES TWC IS YELLING IN ALL CAPS AT YOUR MODEM!!!!!3!#^!!#!@#%31111!!!

MAKE IT STOP!!!!!!

 

That's worse than low signal.

 

heh, seriously.  At what point does damage begin to happen?
