Signal is coming in via optic fiber.
Someone at the company said any modem would be fine.. (probably related to the RV salesman that says 'your 1/2 ton will haul it fine!)
She will need a router/modem that meets the specs of the company providing the fibre optic service. It will have to have a proper input port to accept the fibre optic cable.
If she has had service with them for a while and her current device is old and cannot produce the speeds she's paying for, she might contact the company and ask if they will provide a new one. Many companies will upgrade old devices for free. It's worth a phone call.
