i have a huge problem with my sb6121 it keep dropping my signal i do notice the box restarts by it self it just a big mess i will post link to photo i took before when it works fine and after when i get knocked out
What can i use to drop down my Downstream PowerLevels
FWIW, I would say your issue is your upstream pwr not downstream. 54 is too high. Also your after pic shows channel bonding which is not there in the before pic. You can remove any excess splitters and check all the connections to make sure they are good or call for service.
FWIW, I've seen problems at 50-51 dB even for two channel bonding. This is not an exact science. Hardware and local system specs vary as does the actual accuracy of an given modem's measuring mechanism. Inaccuracies of 2-4 dB are always possible.
