Start with the community FAQ steps: https://community.netgear.com/t5/Orbi-AX/Community-FAQ-My-Orbi-speeds-are-slow-inconsistent-and-don-t-my/m-p/1984305/highlight/true#M7944.  These will diagnose and narrow down where the speed loss is happening, e.g., upstream of the Orbi vs. Orbi wireless vs. wired.  Note that your wireless speeds will normally be well below your 1Gbps service due to AC/AX limits and environmental conditions.  The FAQ gives some representable wireless speeds.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.
