Modems / Mediacom

Mediacom approved modems and what each tier needs

Mediacom needs DOCSIS 3.1 for its 1 Gig tier, while older 3.0 units still provision on lower plans. Owning your modem removes the monthly equipment charge.

NETGEAR CM3000
Multi-gig
NETGEAR CM3000
DOCSIS 3.1 · 2.5 GbE · up to 2.33 Gbps

The one to buy on a gigabit plan or above. No built-in Wi-Fi, so the radio cannot age before the modem does.

Sub-gigabit
NETGEAR CM2500
DOCSIS 3.1 · 1 GbE · up to 936 Mbps

Mediacom modems: questions

Does a better modem raise my data allowance?

No. Allowances are set by your plan, not your hardware. A modem changes speed capability only.
