Cable Modem Signal Levels

Cable Modem Signal Levels

Ever since the days of @HOME, my high-speed Internet access has been via cable modem.  And so far there’s always been a Motorola Surfboard modem to catch that ride.  But at times it’s been a major pain when for several days the ISP (Meep-Meep!) has something go down and the modem lights aren’t all lit solid.  One way to keep tabs on things is by checking your signal levels.  In particular, look for a Downstream Power Level of between -15 and +15 with around 7 dBmV being ideal.  Higher or lower than this range might be a problem.  Check here for more info.
