While NETGEAR provides consumers with one year of protection, Arris offers 2 years of coverage. It is great to get a 1-year warranty but you’ll agree that a 2-year warranty is even better.

If you want to protect your investment to the fullest, you’ll want to add the ARRIS Surfboard SB8200 to your home. It’ll give you more peace of mind than its NETGEAR counterpart. When it comes to the NETGEAR CM1000 vs ARRIS SB8200, the Arris is better in this area.

Make sure that you choose one that stays cool at all times. Both modems will experience some issues in this category. Some people will notice that their Arris SB8200 gets hot during use. For others, the NETGEAR CM1000 will get hotter than usual. If you intend to use one of these modems, you’ll have to monitor it carefully.

Make sure that you place the modem in a location where it will have plenty of ventilation. This will help you avoid problems.

  • Size

Ultimately, you don’t want to clutter your home with a bunch of electronic devices. With that being said, you should take a closer look at both modems. It is important to understand that both modems are compact. However, they’re compact in different ways. With the NETGEAR DOCSIS 3.1 Gigabit Modem, you’ll see that the unit is very thin but tall.

It is much taller than the ARRIS Surfboard SB8200. On the flip side, the ARRIS is shorter but wider. Both can be installed in an assortment of spots without any issues. However, you’ll want to choose the unit that is going to fit your home better.

If you have a small hole under your desk with a short opening, you’ll want to buy the ARRIS. If you have a taller but slimmer opening, the CM1000 from NETGEAR will likely be better for you. You know your home better than anyone so you should decide which will work best for you.

  • Similar Design

The ARRIS SB8200 and Netgear CM1000 share a similar design. Both are free-standing with a flat base to prevent tip-overs. Indicator lights are integrated into the front panel of both units. These are extremely helpful when troubleshooting issues arise. They can help by offering insight into the functionality of the cable modem and wireless router combo.

On both units, the top indicator light shows you that the unit is turned on. Below this light on the CM100 is the DS/US (downstream and upstream) indicator light. When this light is blinking, it is telling you that the unit cannot establish a connection with the network. When the light is solid, the unit is connected to the network.

The setup is slightly different on the SB8200. In this setup, the downstream and upstream are separate lights. Both of these lights are easily distinguishable as they have up and down arrows. However, when the lights are blinking and solid, it means the same thing as the CM1000 singular DS/US indicator light.

The major difference between the two units is their finish. The ARRIS SB8200 has a white finish while the Netgear CM1000 has a black finish. It does not appear there are any other options available besides these two finishes for both brands.

  • No Subscription Fees

When these units are purchased outright, you do not need to be concerned with subscription fees. This is why many consumers opt to purchase outright. It helps reduce their Internet/cable bill by eliminating the cable modem/wireless router rental fee. Consumers are charged anywhere from $10 to $15, depending on the provider. If you multiple your rental fee by 12, you can find out how much you are unnecessarily spending each year. For example, a customer paying $10 per month for equipment rental fees is paying $120 over the course of one year.

By purchasing the unit outright, you can eliminate the monthly fee, which will result in a reduction of your bill.

Cable Modem – No Wireless Router

Both the ARRIS SB8200 and Netgear CM1000 are not combo units. This means the two units are not integrated with a wireless router, only a cable modem. Some cable/Internet customers prefer this setup because it ensures faster speeds. However, there are downsides to having two separate units. One of the most notable downsides is it requires more space. There is also a more complicated installation process since there are two units instead of just one. But, once the installation is complete, it should never need to be repeated unless you upgrade or relocate to a new home.

  • Reset Button

A reset button plays a major in troubleshooting processes. While it is hopefully rare, there will come a time when both units will need to be reset. There are several issues that require the cable modem to be reset to restore normal function. One example is when the connections begin to slow. In this case, the best solution will be a reset.

The reset button is located on the rear panel of both units. On the Netgear CM1000, it is located on the very top of the rear panel where it is labeled for convenience. On the ARRIS SB8200. It is located in the center but on the left side of the rear panel. In this case, the reset button is not labeled but it is easy to determine this is the reset button.

Once the units are turned around, you should be able to access the reset button fairly easily. Both designs will require a paper clip or other semi-sharp object to perform the reset.

Overall Assessment

Finding a modem that works exceptionally well for you, your family, and your home will be difficult. Nevertheless, this is not a decision that you’ll want to rush. You should take your time, consider your options, and choose wisely. The NETGEAR CM1000 is a great modem with blazing-fast speeds but the ARRIS Surfboard SB8200 may be faster.

In terms of aesthetics, the devices are immensely different. Also, it should be noted that Surfboard has a much better warranty. If you want the most protection, you’ll want to buy the ARRIS. But, you shouldn’t ignore the NETGEAR CM1000 because it is a great modem as well.

Which is better? In the end, it is up to you to decide.
