Also purchase that exact same modem on eBay and return the one they're sending you immediately and stop paying $10-12/month to rent a PoS cable modem.
Verizon is a little more tricky than Cable Modems.
FIOS doesn't use modems, they use routers, so search for an older Verizon FIOS Router, turn off that device's WiFi and purchase a solid WiFi router with the savings from your monthly rental fee. Because it looks like you have FIOS-TV as well, you need the Actiontec or Quantum router to deliver data to your other STBs. I haven't done one in a while, but the ActionTech Rev I was the inexpensive and available model, especially with wireless G (hence why I said turn it off and use your own WAP).
