Netgear Cax30 vs Motorola MG8702 DOCSIS 3.1 Cable Modem Which One Gives You Best Value

Netgear Cax30 is a wifi 6 router product with a built-in Docsis 3.1 cable modem in one compact device. This product is an addition of previous most popular product offered by Netgear – the Netgear Cax80.

When the cax30 was released, Arris and Motorola still had not released similar products based on wifi 6 standard. Today you can find Arris products with wifi6 standard were released with its flagships Surfboards g36 and g34 following its success with Arris surfboard Sbg8300 that come with wifi-5 standard. Meanwhile, Motorola has also released the Motorola mg8725 wifi 6 product continuing its success with Motorola mg8702 that still come with wifi5 standard.

Now back to this netgear cax30 product and compare it with Motorola mg8702 see which one is more valuable to your business?

Netgear Nighthawk Cax30

Previously, netgear had released the netgear nighthawk cax80 in addition to the mesh gateway version with its product Orbi cbk752 ax4200 DOCSIS 3.1 cable modem. Netgear always strives to be in the forefront with new technology-based products including modem gateway products with wifi-6 technology where its competitors such as Arris and Motorola had not released similar products at the same time.

Netgear cax30 vs cax80

Unlike Orbi cbk752 which is a mesh gateway with wifi-6 router, both cax80 and cax30 series are wifi-6 routers with built-in DOCSIS 3.1 cable modem, not mesh routers. What is the difference between cax30 and cax80? Please refer to table 1 below which provides a spec comparison between the two gateway series.

Different wifi 6 Network Segment

Both are gateway products based on wifi 6 routers, both of which have built-in DOCSIS 3.1 cable modem but have different wifi network segment design. For the needs of a small to medium size home wifi network and for those of you who need a single device product, the Cax30 netgear is sufficient.

For those of you who need a wifi network with a wider range of around 3000 sq. ft then you can choose cax80 series, of course with faster network performance with ax6000 network. Both support mu-mimo with different number of concurrent data streams.

Of course, cax80 with 8-streams can send data streams to multiple clients faster than cax30 which only 6-streams. Fortunately today you can find there are few models of usb adapters available in the market with wifi-6 technology such as Asus usb-ax56 with 2×2 mu-mimo supports, or few products that you may have never heard of them before such as Mymulike ax1800 usb adapter that the price is almost half the price of asus ax-usb adapter.

Cax80 with 4×4 can send two data streams to two connected devices with USB ax1800 adapters that support 2×2 mu-mimo concurrently.   

Hardware

Although the nighthawk cax80 is designed for higher network segment (ax6000), both of these product series use the same processor in their machine board, embedded with dual core 1.5ghz CPU. Probably we might expect the cax80 series to be equipped with a quad core processor.

Besides that, on the cax80 there is an additional 2.5Gbps super multi Gig Ethernet port that you can use to connect to high speed NAS that comes with 2.5Gbps port as well such as the Asustor Lockerstor 2 AS6602T – 2 Bay NAS.

We’ll take netgear cax30 to compare with latest product offered by Motorola which is still based in wifi5 technology – the Motorola mg8702.

Netgear Cax30 vs Motorola MG8702

When the Motorola mg8725 had not been released to the market, the Motorola mg8702 was quite successful in the market and became the main competitor product of this netgear cax30. And today you can find the new release of Motorola mg8725 which works @ the ax6000 network segment with a built-in modem. In this article we only discuss the comparison between cax30 and mg8702 so that you can have an idea which product suits your business needs at home. See also Arris sbg8300 vs netgear c7800.

Table 2 below shows you spec comparison between Netgear Cax30 and Motorola mg8702 that can be used as reference for spec comparison between the two products.

Network segment

Both products are single wifi router devices with built-in Docsis 3.1 cable modem that can support internet plans up to 1Gbps from your cable provider. The main difference is the wifi technology applied to each product. Motorola mg8702 is still using legacy wifi-5 (wireless ac), while cax30 is already using the latest generation wifi-6 (wireless ax).

There are many questions which is more profitable between a router with wifi ac3200 and a router with ax2700. Regarding total aggregated bandwidth they are certainly different, moreover they are also different in terms of wifi technology applied.

If all your connected devices at home are still based on wifi-5, of course the choice of Motorola mg8702 is more profitable with a wider aggregate bandwidth. However, your gateway router cannot be maximized if some of your new devices are already based on wifi-6. You will find that wifi-5 devices connect faster to wifi-6 router than connect to the same wifi-5 router.

Take a look more details on the following spec comparison table below.
