Recently I have noticed that my internet keeps going off and I have to restart my superhub for it to come back. Sometimes the blue light is flashing on my superhub even and I still can't get any connection to the internet.

I am getting errors such as

SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing

SYNC Timing Synchronization failure - Failed to receive MAC SYNC frame within time-out period

MDD message timeout;CM-MAC

my downstream levels are :

This is still a Superhub 1 if that helps.
