Why would an active cable buffer or active cable splitter screw up the analog data stream to the input of my Shaw cable modem? It seems both my new RCA active cable buffer amp and old Radio Shack active cable splitter interfere with the cable modem to receiving analog data stream.
Shaw tech support thinks there is no reason why the RF from the cable should be fucked with by an active device but it most definitely is (I have the FM trap out). Note that a passive cable splitter or a direct cable hookup works just fine.
Shaw tech support speculated the dB gain was to much for the cable modem input and further speculated that the dB input for the cable modem is restricted to a very small range outside of which it will be either too hot or not strong enough.
I kind’a doubt the cable modem is that picky about the dB input level and I told the Shaw tech support dude as much and he said I am probably right. So what’s the deal?
