When it comes to a robust and high-performing modem-router combo, the NETGEAR Nighthawk CAX80 proves its mettle. Sporting a sleek, black design, this unit offers an impressive range of features that help it stand out in the crowd. The CAX80 is ideal for heavy internet users, like gaming enthusiasts or large households.

We tested this unit with several devices, including computers, game consoles, and streaming devices. It maintained steady, high-speed connections thanks to its DOCSIS 3.1 technology and 32×8 channel bonding. It also has five Ethernet ports (one of which is 2.5 Gigabit Ethernet) and a USB 3.0 port, offering speedy wired connections to all your devices. The device measures 14.29 x 12.44 x 4.65 inches and weighs just under 4 pounds, requiring a reasonable amount of space. It also hosts a range of LED indicators on the front for power, upstream and downstream activity, WiFi status, and Ethernet port status. The rear offers four Ethernet jacks, a USB 3.0 port, and a reset button hidden behind the casing.

The setup process was smooth, from plugging in the coax cable to using the Nighthawk App for network setup. Its compatibility with major cable internet providers like Xfinity, Spectrum, and Cox enhances its convenience. We appreciate seeing the inclusion of NETGEAR Armor. This software safeguards all connected devices, offering a 30-day free trial and making the router an ideal choice for families prioritizing online safety. However, the Nighthawk CAX80’s size could be a downside for some, requiring a sizeable amount of space for installation.

What we liked:

  • Wide coverage area
  • High speeds with DOCSIS 3.1
  • Compatible with major providers
  • Robust internet security

What we didn’t like:

  • Large device size
  • Complex reset button access

NETGEAR Nighthawk CAX30S Modem Router Combo

NETGEAR Nighthawk CAX30S Modem Router Combo

Key features:

  • Dual-Band WiFi 6 (AX2700)
  • DOCSIS 3.1 with 32×8 channel bonding
  • NETGEAR Armor for enhanced security
  • Four Gigabit Ethernet and one USB port

Our journey into exploring the NETGEAR Nighthawk CAX30S Modem Router Combo starts with its substantial size, measuring 10 x 8.3 x 2 inches and weighing a solid 2.1 pounds. Its all-black design and tower-like stature give it an aesthetic edge in the world of networking hardware. During our time with the router, it was evident that the Nighthawk CAX30S wasn’t just built for its looks. The unit is a powerhouse optimized for cable provider plans up to 2Gbps.

NETGEAR-Nighthawk-CAX30S-Modem-Router-Combo

Its dual-band WiFi 6 (AX2700) enables coverage of up to 2,500 square feet and can handle up to 25 devices simultaneously without breaking a sweat. Streaming, gaming, and Internet browsing were lag-free, even with multiple 4K HD streams going simultaneously. This performance can be attributed to the DOCSIS 3.1 technology and the 32×8 channel bonding that the device is equipped with. The router also came with four Gigabit Ethernet ports and one USB 3.0 port.

This feature allowed us to connect computers, game consoles, streaming players, and storage drives. The ability to plug these devices directly into the router provided wired connections that were consistently strong and dependable. The router-modem combo unit is compatible with most cable internet providers. Most but not all. It lacks compatibility with AT&T, Verizon, CenturyLink, DISH, DirecTV, and DSL providers. It also won’t work with bundled voice services.

Moving along, the easy setup and activation process was a major plus. It involved simply plugging in the coax cable and following the on-screen instructions. You also have the option to activate it over the phone if you prefer. Like its CAX80 cousin, this model comes with NETGEAR Armor, an advanced cyber threat protection system. You’ll be pleased to know that you get a 90-day subscription included with the router.

In testing, NETGEAR Armor provided an extra layer of security across all our connected devices. The support of WPA/WPA2/WPA3 wireless security protocols was also noteworthy. Lastly, we like the user-friendly Nighthawk App. For us, it greatly simplified the network setup process. We’re fond of its intuitive interface – anyone should be able to use it without technical knowledge. With all these features and benefits, the Nighthawk CAX30S stands tall as a reliable modem-router combo.

What we liked:

  • Coverage up to 2,500 sq. ft.
  • Handles up to 25 devices
  • Simplified setup with Nighthawk app
  • Reliable wired connections

What we didn’t like:

  • Incompatible with some service providers
  • Limited subscription to NETGEAR Armor

Key features:

Thanks to it, you get multi-gig networking and drastically reduced latency during gaming sessions.

To touch upon another aspect, there’s also better security and speed in this model. In fact, it’s 10 times faster than its predecessor, DOCSIS 3.0. When it came to wireless communication, this router utilized the 802.11ax standard (WiFi 6), pushing our WiFi speeds up to 3 Gbps. However, our tests revealed some caveats. We experienced intermittent disconnects, which required manual reboots. Additionally, the WiFi range and speed needed a bit of fine-tuning for optimal performance – minor nitpicks in what is otherwise a well-rounded contender.

What we liked:

  • Space-efficient design
  • Future-ready with multi-gig support
  • Enhanced parental controls
  • Real-time device monitoring

We experienced higher speeds and expanded coverage, a benefit that’s amplified by its backward compatibility with 32×8 DOCSIS 3.0, 2.0, and 1.1 services. For those needing a powerhouse in both horizontal and vertical home expanses, this one doesn’t disappoint.

Another noteworthy feature is the addition of a high-speed AC3200 WiFi router. Enhanced with AnyBeam WiFi Beamforming, Power Boost, and Range Boost, we found it consistently delivered fast and reliable WiFi. Moreover, its MU-MIMO technology enables seamless communication with multiple devices, which is supposed to reduce buffering significantly. That said, we did experience some occasional buffering in our varied tests.

Switching gears, we like how user-friendly this router is. It features an intelligent mobile app that simplifies setup, network management, speed testing, and parental controls. The device’s size (9.5 x 2.88 x 9.75 inches) and weight (2.15 pounds) makes it a compact addition to your home, fitting easily into any setup. It also features a USB 3.0 Port with DLNA for shared network storage and 4 Gigabit Ethernet LAN ports.

Cable Modem WiFi Router Combo FAQs

A cable modem WiFi router combo is a single device that combines the functionality of a cable modem and a WiFi router. This combo device connects directly to the internet service from your ISP and provides a WiFi network for your home or office.

Why should I choose a modem-router combo over separate units?

Combos serve to simplify the setup process by reducing the number of devices and cables involved. A combo router can also be more cost-effective than buying a separate modem and router. However, if one part fails, you’ll need to replace the entire unit.

Will any modem-router combo work with my Internet Service Provider (ISP)?

  1. Thanks for your recommendation of the NETGEAR Nighthawk AC1900. I just received it today in the mail and all I have to say is, WOW – what a massive difference and huge upgrade in performance. It’s been years since we’ve upgraded our modem and router. Love how it’s a combo so there’s no need to configure both separately.

  2. Thanks for the review. We tried the Nighthawk and the TP-Link Archer CR700 and settled on the TP-Link. TWC offers us download speeds of about 240MBps but our WI-FI speeds throughout the house, regardless of band seems to cap out at about 40 to 50MBps. These speeds are very similar to what we used to get before we upgraded to this newer TP-Link. So, it’s been a frustrating experience that we cannot get higher WI-FI speeds. We tried changing channels and made sure our firmware was up to date but we’re still not satisfied. Any suggestions?

      • Thanks for your recommendation of the NETGEAR Nighthawk AC1900.
        I have the AC1900 C7000 WIFI cable Modem Router.
        All my services are Frontier (TV,Computer, Internet) and have the Unlimited package
        FIOS Bundle Pack.
        Is my AC1900 C7000 modem router compatible with my current FIOS Verizon system?
        There are other AC1900 modems that are. Thank You

  3. Are you aware of any combos that are cable modem router AND are phone capable? I have all of my services (phone,tv, and internet) with Charter Communication .

    Reply
  4. What do you recommend for connecting a regular landline . . . rather . . . how does one connect that landline to one of the above recommendations?

    Reply
  5. Ditto a couple of questions above…..we have a landline through comcast/xfinity and are looking to get rid of the monthly fee for our modem/router. Do any of the above support landlines, too?

    Reply
  6. I believe the same applies for the other carriers ,therefore ill share the information regarding Time Warner/Charter. I recently purchased the Netgear N600 Combo, and being able to change the settings to my liking (Time Warner’s equipment defaults to horrible stock settings), the speed and range is much much better. As far as the phone, I too was worried Id be stuck paying for the rental fee in order to use the phone but was pleasantly surprised. Instead of returning the prior modem phone combo to Time Warner, they change it to disable modem and only function for phone service. This was done over the phone in minutes, they DO NOT CHARGE the rental fee if the modem is only being used for the phone. Technical details explain this but I’ll spare you. It is also nice to be able to place my main cordless phone base in any location, not tied down next to my modem. By the way, after much tweaking plus ddwrt merlin custom firmware, my WiFi speed LOWEST has been around 190 Mbps, highest 280. I’m fully satisfied given wired speeds actually blow away the “cap” of 300.

  7. I had the same issue of connecting the landline to the modem. I have a Comcast/Xfinity triple play, internet, phone and cable service.

    The Comcast crappy modem has a port for the phone.. but the above modems do not, however i brought a phone port to ethernet phone adapter and this solved the problem. Check it out here: http://amzn.to/2f4ePgy

  9. Hello could you give information about using USB 802.11ac Adapters . as for use with arris 7580. And do I need the adapter if using Motorola 7550 . Thanks any fed back would be appreciated. Thank you. Mike.

  10. Didn’t the Motorola win an award in a 3 way test against Arris and Netgear? They tested in a variety of environments and came out on top. Just purchased this to replace a failing sbg6580. Well see how it goes.

    Reply
  11. I’ve been thinking of buying Motorola MG7550 but I can’t find how long /wide the range can be in anywhere online. Even for the question on Amazon, the seller says it’s up to the house construction and how the interference with other device around house is like. I know it is up to those factors but at least somebody can tell the cable modem could cover up to either 1000sf or 5000st, can’t he/she? I want to find out if this could be good replacement for my current modem from xifinity or if I should get Netgear Orbi and connect to my existing modem for our house and our garage which is around 2000sf.

  12. I want the best modem router for a two story house that’s about 3200 Sq ft. Best suggestion to get best wi-fi coverage?

    Reply
  13. Need some advice. Not “tech savvy” at all. Recently switched internet provider from phone company to our local cable company. Are currently using the combo modem/router they supplied. Arris DG2470. Our problem with that being once you leave the room in which it sits wifi signal is almost non existent. So due to that and wanting to get away from the monthly fee for their unit I want to purchase my own. My question is, Is there a combo unit that can provide wifi coverage for a 1200 sq. ft. house or would it be best to purchase separate modem and router?

    Reply
    • You should call your provider and have them reset your wifi signal. Its not sending a strong enough signal when you leave the room and it should be. And you should not have to pay for a signal booster to walk into the next ronn.

      Reply
  14. Great reviews on all three. Your recommendation? We currently use Xfinity as our provider and renting the Arris TG1682G modem/router. I am looking for more speed, eliminate rental fees and more coverage. Home Sq. ft about 2000. We have a bundled package X1 phone, internet and cable.

    Can I pair the ARRIS SURFboard SB8200 DOCSIS 3.1 Gigabit Cable Modem with the AC1900 – NIGHTHAWK® SMART WIFI ROUTER?

    I own the AC1900 router, but I have to upgrade the modem to handle the faster speed I am upgrading with my service provider. So I am trying to determine if I will need a new router as well. If I need a new router, which would you recommend with the SB8200 for a 2800 sqft 2 story. I know walls and location make a difference but general recommendation would be appreciated.

    Reply
    • Yes, you can pair those two together. I would start there, and if you find that it doesn’t provide suitable coverage, you can upgrade your router later.
