Poor Downstream connection

Just upgraded my modem/router. New device (CAX80) has an option to show cable connection quality. 
my internet access and Upstream status are green, but Downstream status is red. 
there is another post with similar issue which has been resolved by replacing the cable line from the pole.

however, we live in an apartment building and no idea where we have the pole line coming into the building and no idea what type of cables and how many splitters are between that line to our unit. My modem/router is directly connected to wall coaxial outlet using a brand new coaxial cable from Xfinity.

See Modem connection report below:

Status: Poor

Action: 
[Downstream Power Level]
Try these actions (Click the Refresh button after each step):
1) Make sure the coaxial cable is tightly connected.
2) Remove any unnecessary splitters.
3) Replace any required splitters.
4) Contact your service provider for troubleshooting help.

Internet Access: Good

Downstream Status: Bad

    Downstream Power Level: Bad
    Downstream power is poor (-23.4dBmV). The recommended level is between -10dBmV to 10dBmV.

    Downstream SNR: Good

Upstream Status:  Good

    Upstream Power Level: Good
