Upstream Channels
Locked ATDMA 2 20480 Kbits/sec 35800000 Hz 40.5 dBmV

Without it , the upstream was at 46-50 and the downstream power levels varied between 4 and -5 throughout the day of where we are currently placed in the cab for the past week. And then when it dropped off it went to the -15 and snr of below 30.

When it drops off now, it goes the those figures and then instantly locks back on (well a couple of minutes) at similar figures quoted. V+ box also reports a signal lock failure in its log so its highly unlikely to be the super hub.

I know snr and power levels vary at different times of the day. But what is the usual variance is +-8 and snr varying by about the same margin (when locked on) usual occurance? (This is without the hdu with it the variance is half that)

BTW when it goes offline its either T4 or T3 timeouts. T4 being the most often occurence.

P.S. Sorry for hijacking the thread from the original post but it does sound similar to what is happening to me. Hope you have luck in fixing it.
