Of course, much more is going on inside the unit. Modem: This part of the combo receives the signal from the internet service provider and can connect that signal to just one device. Router: Connecting to multiple devices, both wirelessly and through an Ethernet port connection, is accomplished by the router.
Multiple ports: Cable modem-router combos typically have at least four Ethernet ports, giving users the option of a direct-wired Ethernet connection to the internet. Multiple WiFi connections: Users with a WiFi-enabled device and the gateway password can access the internet from anywhere in the home.
Guest account: Gateways increasingly include a guest WiFi account that can be protected with a separate password, left open for use with no password not recommended , or disabled by the owner. Downstream channels: Look for a combo with at least 16 downstream channels to handle faster internet speeds. Upstream channels: There will always be fewer upstream than downstream channels.
For example, there may be 24 x 8 — 24 downstream and 8 upstream channels. How do I find out if the cable modem-router combo I want to buy would work with my current internet service? Some independent websites can also provide information on which gateways are supported by your internet provider.
If I buy a super-fast cable modem-router combo, will my internet speed be faster? The main reason to buy a faster gateway is to future-proof it against major speed upgrades from your provider in the next few years. Call your provider or check the news to find out if a speed upgrade is planned. If so, buy a gateway that matches that planned speed. If no speed upgrades are planned, save your money. What does that mean? That number figure, or similar figures like 32 x 8, describe the number of downstream channels vs.
Almost all modems have more downstream than upstream channels. A cable modem-router combo today needs at least 16 downstream channels to handle high-speed internet. These particular modems also use the problematic Intel Puma 6 chipset, which can cause latency issues.
While the modem makers have distributed updated firmware fixes to the ISPs, it is ultimately up to your cable company to support the modem. Multiple Ethernet ports are needed to connect multi-gig Like the other Netgear modems, they have a one-year warranty. While we considered the future-proofing each modem provides, 2. In the chart above , we list which of our cable modem contenders work with which ISPs based on information from each ISP.
Where applicable, we also include the maximum speeds that each ISP supports. It promises speeds of up to 10 Gbps, increased download efficiency, and better queue management for large downloads. This means that more cable operators will be able to offer gigabit speeds over the next few years, and many already do. In order to do so, you would need a router with WAN port aggregation or a 2. Gigabit fiber internet plans are growing more popular, too.
Fiber is generally faster than cable, especially in upload speeds, but it involves added cost for companies because it requires new cables and network architecture. That installation cost is at least partially why Google Fiber dialed back plans for its broadband rollout.
Those who are looking to cut wires entirely out of the equation are starting to get excited about 5G wireless internet to the home and for mobile use. Future-proofing is good in theory but difficult in practice.
It might sound smart to buy the best modem available, but the interplay between the technology, your location, and the ISP means your chances of wasting money on a device that might not work in the future are higher with modems than with other types of electronics. We surmise new modems will feature a 2.
As stated above, this is more of a future-proofing move, as most ISP plans top out at 1-gigabit internet. We'll evaluate them as they become readily available.

If your modem includes a wireless router, you can disable the wireless functionality and use your own separate router, many of which include advanced features like port forwarding or quality of service QoS controls not found on combo units. When shopping for cable modems, finding a model that is supported by your internet service provider ISP is crucial. We consider whether each model we research is supported by top-tier ISPs.
