Remove _all_ those crappy splitters, grab the nearest Comcast tech and ask for a handful of splitters, or visit best buy/radio shack/etc and find some 5mhz-1ghz splitters, usually it's 3.5dB loss per connector, and 7.5dB loss for every split after the first 2 (on any given splitter). Simplified, throw them in the trash, put in new splitters, remove the amp, and see how it does. If problems persist, put the amp back on. > > Often, in the early afternoon, the cable modem will > disconnect and I'll have intermittent use for hours > and then it just as mysteriously comes back and is solid > for many hours again. This is typical, you're within ~10dB of your minimum signal level to hold block sync on your cable modem, and during the afternoon the signal fluctuates due to heat, housewifes watching soaps, and cosmic rays emitted by chipmunks. The signal level dips below the minimum, and poof goes your connection. > I'm using a LinkSys cable modem, and the CD that came > with it is useless.

Cable modems are meant to be black boxes, the cable company doesn't want you knowing what's going on, and in fact, will force new software onto your cable modem without your permission. At best, try searching google to see if it has some kind of minimal web diagnostics page. > > Many thanks, > Chris Schumann -- Matthew S.
