How to Replace and Install a Cable Modem and Save Money
As anyone with cable internet knows ISPs charge a rental fee on cable modems, which most pay since they often think it is too hard to replace it with their own.

Replacing a cable modem is an easy task that most anyone can do and save on the monthly rental fee.

The fees can range from $5-$10 dollars a month which when added up over a year or more can add up quickly.

I recently replaced my cable modem with my ISP and the steps were very simple. I had my new modem installed and running in less than 10 minutes.
 




 
Steps to Replacing Your Cable Modem

  1. The first step is to buy a new cable modem.
  2. DOCSIS (Data Over Cable Service Interface Specification) is the standard used by cable companies to talk to a modem.

    The newest standard is DOCSIS 4.0 with most ISPs using DOCSIS 3.0 and 3.1.

    DOCSIS 3.1 and 4.0 are backward compatible with earlier versions.

    So even if your cable company is still using the old DOCSIS 2.0 standard a new DOCSIS 3.1 or 4.0 cable modem will work.

    Since older versions cost less, money can often be saved buying an older DOCSIS version such as 3.0 or 3.1.

    A DOCSIS 3.0 cable modem has download speed of 1.2 Gbit and DOCSIS 3.1 can download at 5 Gbit.

    Most internet speeds will never reach 1.2 Gbit even with the newest cable modem.

    I bought the ARRIS SURFboard SB6141 DOCSIS 3.0 cable modem since it was the best fit for my setup.

    A DOCSIS 3.1 modem will likely be best for most since it is a widely compatible version and has very good speeds.

    There are cheaper units if you are on a budget and more expensive top-end units that come with more features such as a built-in router.

    I had recently bought a new 802.11ac router so I decided on the ARRIS SURFboard since it is a good mid-range unit.

  3. Look up the number for your cable company tech support line to call in and activate the new unit.
  4. Your ISP will need the MAC address labeled on the router to activate it once it is hooked up.

    The MAC address is usually labeled on the router or in the manual.

    Some companies have an activation page to enter the router MAC address but calling their tech support line may be easier. Especially since you may not have an internet connection during setup.

  5. Everything needs to be plugged in before calling in the new Mac address for activation.

    The coaxial cable simply screws onto its port.

    The Ethernet cable goes to your router which transmits to all your devices.

  7. Call in your new Mac address number to activate the new modem.
  8. Once they have the new Mac address the new modem will be online.

    The router will usually need to be reset to get a new IP address.

    Summary
    Setting up a new cable modem is an easy task and a good way to save on cost long term.

    Deciding on which modem to buy will be the hardest part since there are many available.

    Depending on your internet service provider speeds a top-end modem may not help with faster transfers.

    For example, if your speed is 100Mbps a new modem that can transfer at 500Mbps will never be maxed out and a cheaper one bought.

    If you have an older router buying a combo modem/router is also an option that may help with a faster connection.

    Everyone will have a different setup to fit their internet environment.

    Simply be sure to read the reviews on Amazon, forums, or elsewhere to see which modem is a good fit for you.

    Replacing the cable modem with your own and getting rid of the rental fee from your provider is a good way to lower costs.

    I replaced my modem to save the rental fee. However, I also have an old Optimum router that is giving me problems and has to be restarted regularly, sometimes several times a day. I called Optimum about getting a new one. The person on the phone said, sure, they’d send me a new one as mine is very old. But after another wait on hold, the same person claimed that they couldn’t send one. Instead, I’d have to drive to their office to pick it up — and this is during the Covid-19 pandemic. In addition, I’d have to schedule a technician to come and set it up. They claimed that I’d be unable to “pair” it, or something like that, without a technician coming to my house.
    By the way, every time I’ve ever called Optimum, they’ve played that recording claiming “Due to unusually high call volume, we are experiencing longer than normal wait times.” But long wait times are their normal. They just pretend that that you happened to call at very busy time. Their phone system seems to be designed to insure frustration.

    I just bought an Arris 3.1 modem, and tomorrow I’m gonna call my cable company to have I activated but I’m also going to go buy the Netgear nighthawk X6 to go with it because all I have now is a cheap $60 router with the original Motorola modem that came from the cable company 10 years ago….

    I am setting up service with Comcast and decided to get the ARRIS SURFboard SB6183 to avoid paying their monthly extor…rental fee. I’m excited to pair it with my new 802.11ac router. I hear with the 6183, download speeds with Comcast are higher than advertised. Anything beats the AT&T 6Mbps DSL line my new service is replacing.
