Re: Upstream off the chart: Downstream unchanged...
said by CableMan  :
did you reboot the modem when it was hooked up in the attic?
The modem was off power for about 15 minutes while I moved it from the bedroom into the attic.
said by CableMan :
56 is optimal but very close to the edge. is there an inhouse amp in the attic or before the attic?
There are no amps that I know of. During the test, the modem was plugged into the cable before any splitters. Even on a (first) 2.3ghz two-way splitter, with 6 feet of RG-6, the upstream peaks at 58. I don't know what the upstream in the attic was before last week - I only know what it was in the bedroom, where it used to be 47dBmV... after two splitters (one of which was a FIVE way!).
said by CableMan :
your 47 up is fine but your -18 down is terrible.
Even at -18dBmV my SNR was still over 30, so I wasn't complaining  |
