    i really think its due to the removal of the comcast signal booster/amplifier - even though i had one splitter that was removed when the amplifier was removed my theory is the unamplified signal is causing the occasional drops......having Comcast return and after they tell me for the 3rd time it all looks good i will have them put the signal booster back in.......(instead of just disconnecting the first one the original tech broke it off for some reason)

      Be sure to have them check the speeds at the modem with your wired PC and have them look at the modem logs while they are there.
