Re: Problem with cable modem
Correct - 6.4MHz wide DOCSIS 2 upstream, presumably running on QPSK because the network in the area couldn't handle 16QAM at the time.
You'd have some fun on a 10Mbps upstream on that when it fell back to QPSK or was at it - that upstream delivers 9.

Re: Problem with cable modem
So the guy actually made things worse then?
Will wait and see if I have any more problems with it before getting someone out again though.

Re: Problem with cable modem
Ive been told today that they are going to be putting a bigger cable from the cab into my property. What will they actually do? Will they need to dig my garden up again?

Sounds like a load of rubbish to me. A "bigger cable"? They would need to ensure that the impedance between your wall box (or indeed your cable modem) and the street box is 75 ohms. So that might require a re-pull of the cable to your wall box thriugh the green pipe you mentioned. They'll use the old cable to pull through the new.
HTH.

Re: Problem with cable modem
Thanks for confirming. I did wonder what they meant by bigger cable. They were saying that as I had 2 v+ boxes and a modem what I had now wasn't enough. But everything is working... most of the time.

Get the Tech back and shoot him with some rubber slugs, don't allow him to leave until he's sorted the problem out.

Re: Problem with cable modem
Internet just went down and when it came back I checked the signal levels again and they are now perfect.
Downstream Receive Power Level : 0.8 dBmV
Downstream SNR : 35.3 dB
Wonder what they did, and why it was at this hour.

Re: Problem with cable modem
Could have been a network fault that affected a large amount of people and by doing it at this hour it would not disturb as many people. Im just guessung though

Re: Problem with cable modem
Whatever they did didnt last long. My downstream power level is back down to almost -20 dBmV.
Also, what does "downstream pulse failed" mean? It was in the event log.
