A lot of cable modems have some kind of signal level meter built-in. On
my Motorola SB-4200 it is accessible via http://192.168.100.1/signal.htm
It displays power level in dBmV and SNR in dB. On broadbandreports.com
one can find out that cable modems want something like between -15 and
+15 dBmV (ideally -10 to +10). Is there a similar range for TVs? My
understanding is that TVs require stronger signal than cable modems? If
so, one could measure the signal by connecting the cable modem in
various places...
