Winbox into mikrotik wireless wire in front of router?

Have a unique situation and am stumped.

I need to access a wireless-wire link to check signal strength that is between Cable modem and router. Is this possible? I am remote and can’t go onsite.

Cable modem —> Wireless Wire Set —> Router with public IP.

Is there anyway I can access the wireless wires remotely?

How is the wireless wire configured? And does the cable modem do any routing?
