Re: [Connectivity] Comcast VS. DSL?

jbob,

He had some "piece of cable" (threw it away already), and a very old splitter that he replaced. The piece of cable was about 6 in, and had the RF needled on one point. I don't know much more......but he brought both to me and said I could discard/trash them as he replaced them.

Here is the info, together, you requested:

Downstream Value
Frequency 711000000 Hz
Signal to Noise Ratio 33 dB
QAM 256
Network Access Control Object ON
Power Level 0 dBmV

Upstream Value
Channel ID 1
Frequency 23984000 Hz
Ranging Service ID 432
Symbol Rate 3.200 Msym/s
Power Level 40 dBmV

I wish I had those numbers (I don't) and I get 6mb/386kb reliably.
From memory:
SNR 35
Down -1.2db
Up 45db

Re: [Connectivity] Comcast VS. DSL?

Actually, some of us are guessing she would be fine with SNR consistently as high as yours.

A few are thinking the combination of the SNR of 33 dB, QAM 256 and the Motorola SB5120 (known for sensitivity to noise on the line and especially with QAM 256) may be her problem. If she sees a reading of 33 dB when connected, it is entirely possible SNR drops below that at times and that is why she gets disconnnected.

Occam's Razor. Swap the modem.

go take a picture of what he replaced outside and post it on here and that will show your connections, type of wire, and splitter. if you had an old junky splitter chances are you have old junky wiring to go with it. u can tell whats what just by the fittings they used. and are you sure there is no other splitter. alot of houses have 1 line ran to the attic and there is another splitter up there. or another behind a wallplate feeding something else. where is your modem located in that house?
