Best modem router combos of 2026 for cable internet (and when to skip one)
Buying your own modem router combo can end the monthly equipment fee. It only works on cable internet, and it has to be on your provider's approved list.

A modem router combo, sometimes called a gateway, puts a cable modem and a Wi-Fi router in one box. Buying your own is the most common way to drop the equipment fee from a cable internet bill. It is also the most common way to buy the wrong thing, because a combo only works on cable (DOCSIS) internet and only if your provider has approved that exact model.
These picks are based on manufacturer specs, provider certification lists, and current US pricing. Prices for combos move a lot, so treat them as typical rather than exact.
Modem router combos compared
| Combo | DOCSIS | Wi-Fi | Ethernet | Plan fit | Price |
|---|---|---|---|---|---|
| Netgear Nighthawk CAX30 | 3.1 | Wi-Fi 6 AX2700 | 4 x 1G | Up to 1 Gbps | ~$300 |
| Arris SURFboard G54 | 3.1 | Wi-Fi 7 (quad-band) | 1 x 10G, 4 x 1G | Multi-gig (Arris says up to 2.5 Gbps) | ~$600 |
| Netgear Nighthawk CAX80 | 3.1 | Wi-Fi 6 AX6000 | 1 x 2.5G, 4 x 1G | Gigabit-plus (2.5G port) | $499.99 |
| Netgear Orbi CBK752 | 3.1 | Wi-Fi 6 mesh AX4200 (router + satellite) | 4 x 1G | Up to 1 Gbps | $299.99 |

What to check before you buy
- Your provider's approved list. Xfinity, Spectrum, and Cox each publish one; the device must be on it for your speed tier.
- DOCSIS 3.1. DOCSIS 3.0 combos are cheaper but top out below gigabit and are being dropped from some approved lists.
- Phone service. If you have cable voice service, you may need a gateway with a telephone port, which most retail combos lack.
- Port speed. A plan above 1 Gbps needs a combo with a 2.5 Gbps or 10 Gbps port, or the extra speed never reaches your devices.
Best for most cable plans: Netgear Nighthawk CAX30
The CAX30 is a DOCSIS 3.1 modem with AX2700 Wi-Fi 6 and four gigabit Ethernet ports. It is the right combo for a 300 Mbps to 1 Gbps cable plan in an apartment or average-size home. Netgear holds FCC Conditional Approval, which matters less for this already-authorized model than for its successors.
Best for multi-gig cable: Arris SURFboard G54
The G54 is a DOCSIS 3.1 modem with quad-band Wi-Fi 7 (2.4 GHz, two 5 GHz bands, and 6 GHz), one 10 Gbps port, and four gigabit ports. Arris lists certification from Comcast Xfinity, Charter Spectrum, and Cox. Arris's own page recommends it for plans up to 2.5 Gbps while also mentioning 10 Gbps; plan around 2 Gbps cable tiers and use the 10G port for a switch or fast PC. At roughly $600 it only makes sense if you pay for multi-gig.
Best for range: Netgear Nighthawk CAX80
The CAX80 pairs DOCSIS 3.1 with AX6000 Wi-Fi 6 and a 2.5 Gbps port. Its stronger radios cover a large single-story home better than the CAX30. It is older Wi-Fi at a Wi-Fi 7 price, so buy it on sale or consider a standalone modem plus a Wi-Fi 7 router instead.
Best for multi-floor homes: Netgear Orbi CBK752
The CBK752 is a DOCSIS 3.1 cable modem router with a matching Orbi satellite: tri-band Wi-Fi 6 mesh (AX4200) where the third band links the two units. For a two-story home on a gigabit or slower plan, it replaces both the rented gateway and a separate mesh kit for $299.99.
Cheapest way to stop renting: Arris SURFboard SBG10
The SBG10 is DOCSIS 3.0 with AC1600 Wi-Fi 5 for about $95. It only makes sense on a plan under about 680 Mbps, and only if your provider still lists it. If you plan to upgrade your speed within a couple of years, spend more on DOCSIS 3.1 now.
Combo or separate modem and router?
A combo is the simplest setup: one box, one power outlet, one app. Separate devices are the better long-term buy because Wi-Fi standards move faster than DOCSIS. A good standalone DOCSIS 3.1 modem lasts many years, and you can swap the router or add mesh whenever you like. If Wi-Fi coverage is your main complaint, buy a standalone modem and a mesh system.
Questions we get
Do I need both a router and a modem?
You need both functions: a modem to talk to your provider's network and a router to share that connection and create Wi-Fi. A modem router combo (also called a gateway) does both in one box. Fiber connections use an ONT from your provider instead of a modem, so on fiber you only buy a router.
Is buying a modem router combo cheaper than renting?
Usually, if you keep it for more than a year or two. Cable providers commonly charge a monthly equipment fee for their gateway; check your bill for the exact amount and multiply by 24 or 36 months. A $300 DOCSIS 3.1 combo typically pays for itself in two years. Some plans bundle equipment or unlimited data only with the provider's gateway, so check that before you return it.
Will a modem router combo work with Xfinity, Spectrum, or Cox?
Only if it is on that provider's approved device list. The Arris SURFboard G54 is certified by Comcast Xfinity, Charter Spectrum, and Cox. Always check the provider's current list for your plan speed before buying, because lists change and some plans need specific hardware.
Is a separate modem and router better than a combo?
Separate devices are more flexible: you can upgrade Wi-Fi without touching the modem, and a dedicated router usually has better Wi-Fi and features. A combo is simpler and uses one outlet. If you want mesh or Wi-Fi 7 with good firmware, buy a standalone DOCSIS 3.1 modem plus the router of your choice.
Can you just plug a router into a modem?
Yes. Connect the router's WAN (internet) port to the modem's Ethernet port with a cable, then power-cycle the modem so it hands the new router an address. If the modem is a gateway with its own Wi-Fi, put it in bridge mode to avoid double NAT.
Which is better, Arris or Netgear?
Neither across the board. Arris SURFboard combos have broad ISP certification and the G54 is the most advanced combo on sale; Netgear's Nighthawk and Orbi combos have friendlier apps and FCC Conditional Approval for future models. Pick by your plan speed and your provider's approved list.
