Re: Stuck on qpsk upstream
No you haven't, you're on 16QAM, that's why 3 of the 6 burst types on the Cable Modem Upstream Burst screen say 16QAM.
Only the housekeeping traffic is running at QPSK which is as it should be.
More to the point despite your various threads about this you've not actually pointed to this being a service affecting problem. Whether it says QPSK, QAM16 or supercalifragilisticexpialidocious who really cares so long as everything is working properly? People don't sit there and obsess over the voltage on the power feed going into their home so why the obsession with the broadband if the service is ok?
