Re: Random packet loss 3 techs have been out still no solution.

I've been looking and I can't find a splitter anywhere so is it inside of the cable box? cause otherwise I don't think there is one.

Don't reset anything, copy and paste the signal page in a couple hours, need to see if anythings changed/ corrections gone up.

Right now it looks good, the stuff listed doesn't agree to any local TV transmit frequencies other than Ch 50 @ 693 mHz

Nie9001,

  • If I read your post correctly, you have 2 active wall ports, upstairs and down. see next bullet.
  • read entire list but see number 6. all unused active lines have to be terminated. newer modems are more sensitive to this than previous ones.  Cable modem and wiring checklist
  • in order to have 2 active ports there is a splitter somewhere. when you find it, post a picture.

Isnt it possible they ran 2 seperate lines from the box instead of splitting. Regardless next time it acts up I will ask that the splitter be checked by a tech.

Very unlikely. Start outside the house at the grounding block. Trace the coax inside

My problem isn't going anywhere either. Signal page looks identical from a few days ago and packet loss is still hoevering around 5% consistently.

Re: Random packet loss 3 techs have been out still no solution.

What suburb of Cleveland? and which corner of it or a main intersection?

 

 

For your downstream levels looking good and at the high side your upstream is too high, it should be lower.

Observer

Re: Random packet loss 3 techs have been out still no solution.

Cleveland Heights - main intersection should be Monticello and Noble (here's a map link - https://goo.gl/Izyw9u). I have a 6dB attenuator to bring the downstream levels down to a reasonable amount. What can I do about the upstream?

Expert

Re: Random packet loss 3 techs have been out still no solution.

Remove the attenuator...  The modems can go upto  +15 downstream.

do you have cable tv? an actual 3.5 db loss 2 way splitter would be better with the 2nd port terminated.

 

This may also be a corroded center conductor either at the grounding block ir inside. All copper must be shiny and extend 1/8" beyond the nuts.

Corrosion will cause excess loss at the upstream low frequencies and sometimes not affect the high frequencies.

 Also some in house amplifiers hafe 0db gain on upstream and 10+ on downstream... This is a single family house i assume

 

The high uncorrectables may also indicate a corrosion problem. I think TWC needs to come out

 

 

 

The head end is at 7 Severance circle. There may be a bad amp module out on the street somewhere.
