The high levels were actually at the tap, so they are upstream from me.
Now my upstream levels increased by about 4 dB and my downstream ones decreased 4dB. Note the signals I posted last night are with my modem now off the 3.5 dB level of my outside split. Originaly it was off the 7 dB, so even though the signals are "the same" they're actually much worse.
Every time I schedule a tech to come out, the signals suddenly go back to normal (47 dB power up, 35/36 SNR down) since they seem to cycle every 2 days or so. Two days of borderline poor signals and two days of okay signals.
What I have now is actually usable as my my TiVo and modem are reporting errors are being corrected, but the signals shouldn't be that bad as there is very little wiggle room. When the signals drop a bit I start getting packet loss and TV picture blocking.--
