More information needed.

Connection path being the following line diagram where ----> represents an Ethernet cable:

ISP === (coax, DSL, fiber) ===> Modem ---->[WAN Port] Router [LAN Port] ----> [LAN Port] Office Wifi Access Point ~~~~> Wireless network devices

With other Router LAN ports -----> Wired network devices.

Modem and Router may be combined.
