Power Levels?

Hi,

How do my power levels look on my superhub 2? I have a strange issue were all 8x downstreams can be around 0 and my 2x upstreams around 48-49 which is normal, as you can see from below the downstreams are around -3 and the upstreams are around 54, can someone explain to me what causes the upstream and downstream to change like that, I have checked all the connections myself and they are firmly tight.

Tivo power level for upstream is also 54, just checked now 21:45 and it dropped to 52 and now 21:51 it has gone to 57, superhub 2 is still at 54 at this moment.

Update 22:13

Tivo power level for upstream is now 48, superhub 2 is 52.75 and 53.50.

Thanks for looking at my post.
