NETGEAR N600 C3700

Solid Budget Modem Router Combo

  • Support For Xfinity (Comcast), Spectrum, And Cox
  • Number Of Downstream and Upstream Channels: 8×4
  • Number Of Ethernet Ports: 2 Gigabit Ports
  • Max Download Speed: 340 Mbps
CHECK PRICES

The N600 from Netgear is a solid budget modem router combo that offers DOCSIS 3.0 support and dual-band Wi-Fi coverage. The max download speed is 340 Mbps but real-life tests show that, when using 250 Mbps connection, wireless performance caps at about 130 Mbps when near the router and at about 40 Mbps when a few feet away from the unit. These aren’t impressive numbers.

Wired performance is much better but aging 802.11n (Wi-Fi 4) technology (other devices in this list have 802.11ac or Wi-Fi 5 support) combined with poor performance and no extra features puts this one behind the ARRIS Surfboard SBG10, despite the Netgear C3700 coming with a USB 2.0 port on the back.

Further, the SBG10 comes with 16×4 downstream and upstream channels while the Netgear C3700 offers just 8×4 channels. If you want to save some money – get this one, it’s noticeably cheaper than the SBG10. But if you want the best budget modem router combo – get the SBG10.

Pros:
  • Affordable
  • Supports All Major ISPs
Cons:
  • Doesn’t Support Wi-Fi 802.11ac Standard (Wi-Fi 5)

CHECK PRICES

The Orbi CBR40 from Netgear isn’t the fastest modem router combo around but it’s the best one thanks to great performance, excellent range, and a plethora of extra features. This one doesn’t support DOCSIS 3.1 standard as the NETGEAR Nighthawk C7800 but that doesn’t really matter since max download speed is rated at 1.3 Gbps.

DOCSIS 3.0 support and 32×8 downstream and upstream channels enable excellent performance. Tri-band Wi-Fi support (1×2.4Ghz at 400 Mbps and 2x5Ghz at 866 Mbps) along with MU-MIMO guarantees excellent connection speed for every wireless device, no matter how many are connected to your Wi-Fi network at once.

Real-life tests confirm that. Using a 175 Mbps internet plan results show a max speed of 171 Mbps when next to the device. At 10 feet from the CBR40 and with 17 devices connected to the wireless network at once, the max speed was 86 Mbps. At 50 feet with multiple doors and walls between the modem router combo and the device used for testing, the max speed was almost 70 Mbps. Finally, at 100 feet with multiple doors and walls, speed was almost 25 Mbps.

Further, this unit is compatible with Orbi mesh wireless extenders, which can greatly increase coverage. You also get lots of extra features (parental controls, multiple security standards, beamforming, etc.) and support for Comcast Xfinity, Cox, and Spectrum ISPs. The only major downside, aside from the high price, is the lack of USB ports.

Pros:
  • Fast Performance
  • Excellent Range
  • Support For Mesh Wireless Extenders
  • Supports All Major ISPs
  • Lots Of Extra Features
Cons:
  • Expensive
  • No USB Ports

How To Choose A Modem Router Combo

As we’ve said, buying a modem router combo is a great way to save money, space, and to get the entire internet setup in one device. While these devices seem simple enough (just hook it up to the cable and that’s it) there are several features you should look for.

As for the things you should look for regarding the router part of the combo, we’ve already covered them in great detail in our best routers under $100 piece. Now, there are some differences when it comes to modem router combos, but they are few and far between.

First of all, disregard Wi-Fi 6 support. At the moment, there aren’t any modem router combo devices that support the Wi-Fi 6 standard. They should arrive later this year but at the moment, you won’t find one.

Instead of focusing on Wi-Fi 6 support, just get a combo device that supports Wi-Fi 5. If you need Wi-Fi 6 support well, forget about getting a combo device and just get yourself a nice Wi-Fi 6 router.

Other than that, the info we shared in our routers under $100 piece should cover all the basics when it comes to the router part of a modem router combo device. Now, let’s talk about what to look for regarding the modem in your next modem router combo device.

Make Sure Your Next Modem Router Combo Supports Your ISP

Yeah, you don’t want to buy a combo device and then realize your internet provider doesn’t support it. The best modem router combo for Xfinity doesn’t have to be the best one for Spectrum or Cox.

Hell, if a modem works great with Cox, it doesn’t have to support Comcast or Xfinity. If a friend has a modem router combo and if the device works great with their ISP that doesn’t mean it will work with your ISP. The good news is that there are multiple ways to check whether or not you can use a specific modem router combo with your ISP.

The easiest one is to simply check specs of the combo device you’re eyeing. Each modem router combo should list supported ISPs. Many models support all major cable internet providers. But it’s best to just check supported ISPs. The list should be found on official specs pages.

The second way of inspecting whether or not your ISP supports a combo device you want to buy is to visit approvedmodems.com or similar sites and check compatible modems.

If you happen to use a small ISP that operates only in your area, chances are you won’t find it on the approved modems website and modem router specs pages won’t list it. The best way to check if a modem works with your ISP is to call them and ask them yourself.

Finally, before hooking up the device, learn how to activate the device with your ISP. Some ISPs offer automatic activation, others need a device’s MAC address, and some have their unique ways of activating new modems.

Get A DOCSIS 3.0 or 3.1 Device

DOCSIS stands for “Data Over Cable Service Interface Specification.” All cable internet modems have to support the DOCSIS standard. And as is the case with most tech standards, this one has multiple versions. DOCSIS 2.0 and older cannot support speeds over 40mbps so you don’t want a device that comes with DOCSIS 2.0.

You want to get either a DOCSIS 3.0 or 3.1 device. DOCSIS 3.0 devices can handle download speeds up to 1 Gbps and upload speeds up to 200 Mbps. DOCSIS 3.1 devices have capacity for 10 Gbps download and 1-2 Gbps upload.

Now, most users’ internet falls into DOCSIS 3.0 bandwidth. If you have upload speeds that exceed 200 Mbps you should get a DOCSIS 3.1 modem router combo devices. There’s also the DOCSIS 4.0 standard but that one is yet to debut on upcoming devices.

Don’t Let The Number Of Upstream And Downstream Channels Confuse You

Modem router combo specs include the number of downstream and upstream channels and they look something like this: 16 x 8. The first digit stands for the number of downstream channels, the more downstream channels the higher max download speed. 16 channels should be enough for all sans the fastest internet plans.

When it comes to upstream channels, 4 is the standard but if you have multiple gamers in your household or if you have a plan with fast upload speed try getting a device with 8 upstream channels.

Check Download And Upload Speeds

DOCSIS standard regulates maximum download and upload speeds supported by different versions of the standard. That said, if a modem router combo device supports, for instance, the DOCSIS 3.0 standard that doesn’t mean the device can handle 1 Gbps download and 200 Mbps upload bandwidth.

In order to find out maximum download and upload bandwidth of each model, check out the official specs for each device. This is especially important if you own a super-fast internet plan with high upload speeds because most devices support lower upload speed compared to the download speed.

The best way to find out how a modem router combo behaves in real-life scenarios is to look for official reviews. If a model you’re interested in doesn’t have any official review online, read user reviews.

Advantages Of Modem Router Combo Devices

There are a lot of advantages when it comes to owning a modem router combo instead of a separate modem and router. Here are the most important ones:

  • It’s Cheaper To Get A Combo Device Than Two Separate Devices
  • Modem Router Combo Takes Less Space Than Two Separate Devices
  • It’s Easier To Setup One Combo Device Than Two Separate Devices

Downsides Of A Modem Router Combo Devices

Getting a modem router combo instead of two separate devices also has its downsides. The biggest disadvantage is that there aren’t any Wi-Fi 6 combo devices at the moment. That’s cool if you use an older laptop, smartphone, or a USB Wi-Fi adapter. But if you own the latest laptop or a 2019 or 2020 flagship smartphone you won’t be able to use their maximum wireless speed.

Next, in case you switch your ISP there’s a chance your new ISP won’t support your current modem router combo. So, instead of just getting a new cable modem you will have to spend more money on getting a completely new modem and router setup. Also, modem router combo devices are usually slower on average than wireless routers.

Finally, if you move to a larger household your current modem router combo might not be powerful enough to fully cover your new home with the wireless signal. Now, if you owned two separate devices you could’ve just bought a new router for long-range but if you have a combo device, tough luck. You’ll either have to spend money on wireless range extenders, get a new combo device with better range, buy new router and modem, or buy a mesh router and a new modem.
