Can I use my own modem with Atlantic Broadband (now Breezeline)?

Yes, with a restriction: the device has to appear on Atlantic Broadband (now Breezeline)'s published approved list. In their words: "Unless you're within a Fiber service area or have WiFi Your Way™, you're welcome to use your own modem." Also: "Can I purchase a modem instead of leasing one from Breezeline? Yes, but there are a few things for you to consider" — Breezeline will not support customer-purchased equipment, and 24-hour technical support is leased-equipment-only.

What DOCSIS version does Atlantic Broadband (now Breezeline) require?

"DOCSIS 3.1" — the device table splits it into "3.1 High-Split" and "3.1 Mid-Split". Text: "If a device is on our Customer Owned Equipment (Approved Devices) - DOCSIS 3.1, Breezeline may be able to update the device's software as long as the device manufacturer provides support for the model."

Do Atlantic Broadband (now Breezeline)'s requirements change with my speed tier?

Stated as max speeds per DOCSIS class in the device table: "Modem / 3.1 High-Split / Netgear / CM3000 / 2.5 Gbps / 500 Mbps" and "Modem / 3.1 Mid-Split / ... / 1 Gbps / 200 Mbps"; "Gateway (Modem + WiFi Router) / 3.1 Mid-Split / 1 Gbps / 200 Mbps". Also: "Depending on the equipment type and model, you may not receive the maximum download and upload speeds or WiFi performance that's available with your rate plan."

Can I use my own router with Atlantic Broadband (now Breezeline)?

Yes — combined units are an explicitly permitted category. The table has a separate device type "Gateway (Modem + WiFi Router)", DOCSIS 3.1 Mid-Split, listing Arris SBG8300, G34, G36, G54; Netgear CAX30, CAX80, CBR750, C7800; Motorola MG8702. The PDF also explains the distinction: "A WiFi gateway has a built-in WiFi router... whereas a modem/ethernet gateway generally has from one to four ethernet ports... but no WiFi capability."

What does Atlantic Broadband (now Breezeline) not allow?

Fiber customers — "If you have fiber service from Breezeline, leased equipment is required." Voice customers — "Breezeline Voice customers may only use equipment leased from Breezeline." WiFi+ / WiFi Your Way™ — "Breezeline WiFi+ is exclusively available to internet customers using equipment provided by Breezeline." Non-listed devices can be refused at activation: "If the device you are trying to add is not on the Approved list the following screen will appear."
