When is DOCSIS 4.0 coming?

The DOCSIS 3.1 cable technology is currently the fastest cable technology available in the market. However, the next generation of cable technology, DOCSIS 4.0, is expected to support up to 10Gbps – also known as 10G internet technology. It’s unclear when this technology will become available, but it could be in the next few months or years.

In the meantime, there are already a few high-speed WiFi 6E products on the market that come with a multi-gig 10Gbps WAN port. This port is designed to be ready for the future release of DOCSIS 4.0, which will support even higher internet speeds. For example, the Netgear Orbi rbke963 axe11000 and TP-Link Deco Xe200 Axe11000 are both equipped with this multi-gig 10Gbps WAN port.

The next generation of WiFi technology, WiFi 7, is just around the corner and has already been applied to a few models of WiFi 7 products. One example is the TP-Link Deco Be95 Be33000, which is showcased on Amazon and is based on this future WiFi 7 technology.

If you require a high bandwidth internet plan, it’s essential to have a high-speed DOCSIS 3.1 cable modem. The Arris Surfboard S33 and its competitor, the Nighthawk CM2000, both offer high-speed cable modem options that are compatible with DOCSIS 3.1 and can support fast and reliable internet connectivity.

Stylist Design

The Surfboard S33 has a stylish design that features a beautiful model with smooth curves and no sharp corners. The body of the modem has vents on the upper side, as well as on the lower left and right sides, with deep grooves that give it an artistic appearance.

In comparison, the Nighthawk CM2000 from Netgear has a solid and sturdy body without the graceful curves offered by the S33. While it may not be as visually appealing as the Surfboard S33, the Nighthawk CM2000 is designed to be robust and durable, ensuring that it can withstand regular use without any issues.

Multi Gigabit Ethernet port

There are many WiFi 6 routers available today that come equipped with a multi-gigabit Ethernet WAN port, allowing them to take full advantage of the multi-gigabit Ethernet port of the DOCSIS 3.1 cable modem. One example is the TP-Link Archer ax11000, which comes with a 1×2.5Gbps WAN port.

Both the Nighthawk CM2000 and the Arris Surfboard S33 are equipped with a 1×2.5Gbps Ethernet port. However, the Surfboard S33 also comes with an additional 1x Gigabit Ethernet port that can be used as a separate network. This port can be used to connect to other WiFi 6 routers with a gigabit WAN port, such as the Asus rt-ax55 ax1800 router. This allows for even greater flexibility and control over your home network setup.

Doesn’t support LAC

It’s worth noting that while the Surfboard S33 comes with two Ethernet ports, it does not feature link aggregation. If you plan to use the second Ethernet port as a separate network, you would need two separate public IP addresses if you want to create two separate networks from a single Arris S33 modem. This is because each network would need its own unique public IP address to communicate with the internet.

Normally, internet service providers (ISPs) only provide one public IP address per residential account. However, some ISPs may provide additional public IP addresses for an additional fee or for business accounts. Without a second public IP address, it may be possible to create a second network using Network Address Translation (NAT) or a Virtual Local Area Network (VLAN) setup, but this can be more complex to configure and may not be suitable for all network setups.

The Surfboard S33 sets itself apart from other cable modems that have link aggregation between their two Ethernet ports, such as the Netgear CM1100. While there are several models of WiFi routers that come with a WAN port that supports aggregated link, which combines the WAN port and one of the LAN ports (usually the first LAN port), the S33 does not offer this feature.

For example, the Netgear Nighthawk RAX78 comes equipped with 1x Gigabit WAN port and 4x Gigabit LAN port. You can take advantage of the WAN port and the first LAN port (located next to the WAN port) to activate the aggregated link WAN port and connect to the Netgear CM1100 cable modem. However, this feature is not available with the Surfboard S33.

If your current WiFi router only has a 1 Gigabit WAN port and supports an aggregated WAN port with a LAN port, it may be a good idea to invest in the Netgear CM1100 cable modem. This modem is equipped with two Ethernet ports that support an aggregated WAN port, allowing you to take advantage of the faster speeds offered by a multi-gig Ethernet port.

Surfboard S33 vs Netgear CM2000

The Arris Surfboard S33 is available at a much lower price compared to its competitor, the Nighthawk CM2000. Although both products are technically similar, the Surfboard S33 has an added advantage of having two Ethernet ports, while the CM2000 only has one.

Ethernet Port

Notably, the Surfboard S33 comes equipped with two Ethernet ports, which allows for the creation of two separate networks. If you have two different wifi routers, you can establish two distinct wifi networks. However, as mentioned earlier, a second public IP address is necessary to create the second network.

A premium wifi-6 router that features a multi-Gigabit WAN port, such as the TP-link Archer ax11000 wifi-6 gaming router, can maximize the 2.5Gbps multi-Gigabit Ethernet port of the Surfboard S33.

Take a look at table 1 below which shows technically a comparison table between Arris Surfboard s33 and Netgear Nighthawk cm2000.
