Plus, you don't have to worry about compatibility or replacing the unit yourself. Before we dive in, let's talk about modem technology, which affects your maximum upload and download speeds in addition, of course, to the service offered by your cable provider.

You'll definitely want to upgrade your modem if it only supports DOCSIS 2.0, as you'll be sacrificing speed, and many ISPs are encouraging their customers to switch to 3.0 as they won't continue to support 2.0 modems for much longer.

In any case, it's worth contacting your ISP if you're not sure about compatibility.

I was researching on upgrading my router and then i started reading up on modems and now i'm wondering if a modem will affect speed. I have saw 10/100/1000 Modems online, which im guessing is better. I plan on replacing my Wireless G Router with a Wireless AC Router, and wanted to make sure my routers speed isn't handicapped.

This speed will eventually require the DOCSIS 3.1 standard, which is backwards compatible with DOCSIS 3.0.

We found two newer modems that feature DOCSIS 3.1 compatibility: the Arris Surfboard SB8200 (9) and the Netgear CM1000 (0).

Although upgrading can be an inconvenience, upgrading to the newer technology will ensure your internet service remains reliable and capable of receiving our fastest speeds for the most enjoyable online experience.

If you have any questions concerning upgrading your modem or compatible modems, please contact our customer service department.

One modem we recommend, the Arris Surfboard SB6190 has 32 downstream channels and eight upstream channels, which has a maximum download speed of 1.4 Gbps.
