Approved Modems

Armstrong provides a modem with Zoom. Armstrong does not charge a lease fee for the modem we provide. You are permitted to purchase your own modem from your favorite retailer provided that modem is on the list below and is minimally DOCSIS 3.0 compliant with 8 downstream channels or greater. Older modems can affect download and upload speeds and are not permitted. Purchasing your own modem will not affect the monthly fees you pay for Zoom Internet.

If you are purchasing a modem from a retailer, please make sure the modem you are purchasing is on this list of compliant modems:
