High Speed Internet/Voice 2-Port Modem (ARRIS TM1602) for use on the Optimum network - Supports Optimum Voice - SKU 1000182

I can save enough from my cable bill to pay itself in ten months. Easy to install. Worked right out of the box.

Purchased this so I save a $10.00 monthly charge from optimum

I replaced my slow cable modem that I was paying 10 per month (over 1500 over last 12 years) with a fast one for 99. I assume I will not have any issues since its supported by my cable company but time will tell.

I bought this modem and saved $10.00 a month on the one I was renting from my provider, Optimum! I disconnected the rented one, hooked up this identical replacement, called in this unit's MAC number to Optimum to complete the connection, and returned the rented one back to the Optimum store. This one works perfectly giving me the steady download speed of 422 Mbps and upload speed of 42 Mbps that Optimum is providing me. It will pay for itself in 11 months and after that I will save $120 a year off of my cable bill!

did not come with any written instructions---and i do not know if it needs a FIRMWARE update---please advise

Great
