Thanks for posting and a warm welcome to the community.
Sorry to read that you are experiencing slow broadband speeds.
From the stats you posted it is only showing 4 downstream channels, however from this side it is now fully locked onto all channels and within the correct ranges. There are no faults reported and the traffic on the network is running low.
Are you able to complete speed tests through a wired connection at different times of the day please so we can see what you achieve?
