The Hitron CGNM-2250 is a NAT-capable cable modem and wireless access point that supports standard networking features, including wireless connectivity. The Netgear AC750 WiFi extender is designed to work with most standard WiFi routers by extending their wireless signal. Since the CGNM-2250 functions as a wireless access point, it should be compatible with the Netgear AC750 extender, provided they are configured correctly.
