11 Best RCN Compatible Modems in 2021

If you click on any link on Freedom251.com & decide to buy it, we may earn a small commission.

You need a powerful and efficient modem that comes with the latest technologies like DOCSIS 3.1 to take full advantage of RCN’s high-speed internet plan that you have subscribed to. It doesn’t stop there; you just can’t order any other modem and get your internet-powered up. To be able to connect with RCN, you’ll need a modem that’s approved by them.

Most of the cable internet providers, including Mediacom, Optimum, Suddenlink and WOW! provide outdated equipment; that’s why you don’t get the fullest possible speed despite having a high-speed internet plan. The fact that makes it even more disappointing is you pay $10/month as a rental for such outdated internet equipment.

You could just search on Amazon or Best Buy to find an endless list of modems that are compatible with RCN, but if you’re looking for expert advice to choose the right model, then here’s a list of devices that we’ve tested with RCN in various locations.

Our main aim with this article is to help you find the modem that’ll work best for your usage, that’s why we tested 43 different modems in 13 locations in Massachusetts, New York, Illinois, and Pennsylvania and are here with 11 different modems and modem/router combos that are highly compatible with RCN.

So, shall we begin with the list?

  • Technology: DOCSIS 3.1
  • Downstream/Upstream Channels: 32 x 8
  • Download/Upload Speeds: 2Gbps / 680Mbps
  • Modem/Router Combo: No

Despite reviewers finding it hard to identify RCN compatible modems that can manage the high-speed Gig-level internet plans, we have finally zeroed in on the Netgear Nighthawk CM1100. While this appliance boasts higher speeds, reliable connectivity, and exceptional affordability, the entire specs sheet is actually in line with the user preferences and the latest technologies.

For starters, the Netgear Nighthawk CM1100 exhibits the DOCSIS 3.1 technology, which translates into 32×8 streaming channels. Despite packing in 32 downstream and 8 upstream channels, the gadget is still 10 times faster as compared to DOCSIS 3.0 modems with a similar channel spread. Therefore, it wouldn’t be wrong to tag this as a future-proof modem, capable of helping you reach speeds close to 2Gbps, provided the ISP permits the same.

The existing DOCSIS 3.1 technology is further bolstered by the channel bonding and link aggregation support. Besides, two downstream and two upstream channels are stacked with OFDM and OFDMA technologies, precisely to transmit data at enviable speeds even during peak hours.

Not just that, this is one of the few RCN modems to offer the QoS support for prioritizing network traffic as per requirements. Moreover, when tested in the speed labs, our experts could reach download speeds of up to 600Mbps for certain mid-range RCN plans.

Coming to the structural attributes, the Netgear Nighthawk CM1100 flaunts an upright design and weighs close to the 1-pound mark. Besides, you get access to two gig Ethernet ports, making this a multi-gig unit, with auto-sensing functionality to rely on. This means you can make good use of the RCN-offered internet package even in the wired form if you aren’t planning to set up a wireless network.

As far as compatibility is concerned, the Netgear Nighthawk CM1100 works well with Cox, Comcast Xfinity, Spectrum, and other relevant cable ISPs. Furthermore, this is one of the few DOCSIS 3.1 modems that offer IPv6 support for addressing selecting networks and internet protocols. Besides, this is one backward compatible modem that works perfectly with the DOCSIS 3.0 hardware.

Moreover, if you are planning to pair a wireless router with the same, we would urge you to consider an Archer device with Wi-Fi AX compatibility to make the most of the speeds exhibited by the Netgear Nighthawk CM1100. Overall, if you are looking for a budget-friendly, future-proof, and relevant modem for the RCN-compatible services, the Netgear Nighthawk CM1100 is the perfect option, more so due to the easy installation and setup.

Pros
  • 10x faster as compared to DOCSIS 3.0 modems
  • Two Ethernet ports for better-wired connectivity
  • Boasts of link-aggregation support for reach multi-gig speeds
  • Backward compatible
  • Doesn’t run hot
Cons
  • Experiences compatibility issues with certain modems
  • Experiences connection drops

2. Best Runner Up: Arris SurfBoard SB8200

  • DOCSIS 3.1
  • Downstream/Upstream: 32 x 8
  • Download Speed: Up to 10Gbps
  • Modem/Router Combo: No

With the evolving needs of high-speed internet and constant connectivity, we all need a device that can do that effectively. The Arris SurfBoard SB8200 is great for streaming 4K movies, playing virtual-reality games and streaming movies from quality sources using the 32 x 8 channels. It does all this without a lag due to the DOCSIS 3.1 tech used.

The modem is easy to set up. By hooking it to the system and following the instructions, you can set it up without the help of technical support. However, if you’re still unable to set it up, you can contact RCN’s customer support and ask for help.

The Arris Surfboard SB8200 is capable of 10Gbps downloads. In 7 locations where we tested this, we could get steady download speeds up to 2Gbps and upload speeds at 1.3Gbps.

When left unattended for long hours, this modem tends to get locked and then you may have to restart it to make it operational again. Instead of that, power off when not in use and restart when you have to use it to save on time and optimally use energy.

With intensive usage, the modem gets too warm for comfort. You can combine it with a cooling pad or a USB fan to absorb all the extra heat and keep your device cool. This is only a modem, so make sure your cable operator and router are compatible with this before buying.

Pros
  • Easy to install and set up
  • Durable
  • Value for money
Cons
  • Locks up-constantly have to restart
  • Heating
  • DOCSIS 3.1
  • Downstream/Upstream: 32 x 8
  • Download/Upload Speed: 1Gbps / 500Mbps
  • Modem/Router Combo: No

In today’s world where high-speed internet is the order of the day, the Netgear CM1000 does a decent job of catering to it. Be it high-end gaming on a laptop or heavy multitasking, this DOCSIS 3.1 based cable modem can support it all without a glitch.

It is fairly easy to set up and install. All you need to do is plug it into your computer and follow the instructions on the website. Post that, it is ready for use in minutes. And since it’s approved by RCN, you don’t need any technical support to setup. Now, we understand that intensive gaming means excessive heating of the modem. To ward off the heat, you can use a small USB fan or keep it in a cool corner.

When compared to other modems with similar specifications, this is priced slightly higher. But do factor in the 32 x 8 channel bonding and the high-speed connectivity before making a decision. It is capable of steady 1 Gbps downloads and 500 Mbps uploads for several hours.

Since it is NOT a modem/router combo, you’ll need to get a separate Wireless router for WiFI. Also, this modem is compatible with a selected routers only, so make sure that it works with the router you’re planning to get or already own.

Pros
  • Backward compatible
  • Easy to set up and install
  • Durable
Cons
  • Heats up quickly
  • Steep price point
  • DOCSIS 3.0
  • Downstream/Upstream: 32 x 8
  • Download Speed: 1.3Gbps
  • Modem/Router Combo: Yes

What if there was a device that could cater to multiple devices accessing the internet without a lag. The Asus CM-32 modem-router combo does that seamlessly. If you place this DOCSIS 3.0 based device in a central location, it offers great coverage across all rooms of the house.

This device is also fairly easy to install and set up. You can set it up yourself with the technician on the phone, and it is ready for use in a jiffy. In spite of intensive gaming and multiple websites running parallelly, the modem doesn’t give off any heat, which is a great plus and makes it durable equipment.

Also when you are live streaming high-quality videos and engrossed in multiplayer virtual reality gaming, the device does beautifully. There is no spotting or pixel blur or lag due to 1.3Gbps download and 600Mbps upload speeds which is something you experience on the internet equipment you get for the rental.

Now, the price point may be a bit high compared to other devices, but do factor in the 32 x 8 channels and high speed before making a decision. This is a modem and router so you can buy it without a worry.

Pros

It is simple to set up, and you can do it on your own without the assistance of a technician. The download speed of 686 Mbps and upload of 300 Mbps is quite decent. It uses 16 x 4 channel bonding that can connect a fair number of devices.

We understand that heavy usage may cause this DOCSIS 3.0 modem to heat up, and that heat is quite troubling. You can use a USB fan or keep it in a cool corner to ward off the heat.

Sometimes, the lights on this device can get very bright at night and may interfere with your gaming. Keep this in a corner to avoid the glare. So if you don’t have the perfect corner setup avoid getting this.

Pros
  • Good speed
  • Easy installation
  • Reliable
  • Self-managed dashboard
Cons
  • Requires frequent reboots
  • Degrades over time
  • Wi-Fi stops at intervals
  • DOCSIS 3.0
  • Downstream/Upstream: 4 x 4
  • Download/Upload Speed: 172 Mbps / 131 Mbps
  • Modem/Router Combo: No

The Arris SurfBoard SB6121 with the Motorola logo in front is a reliable modem. We tested it at our lab, and it was consistently able to provide above 172Mbps download speeds and 131Mbps during uploads.

To put that in context, it takes about 20 Mbps to watch streaming 4K video. It is quite challenging to consume in excess of 100Mbps consistently over a home network. So be assured that you have at least 50% overhead should you need it.

The Docsis 3.0 tech-based modem has 4 x 4 channel bonding. That is not an ideal configuration but enough to run a UHD tv, a gaming device, and YouTube at the same time. The same model is also available with 8×4 and 16×4 channel bonding but at a slightly higher price.

The rear plate has a single Ethernet port.  It is advisable to connect the modem to a router and distribute the incoming data among devices. It is not a modem and router combo.

The form factor is vertical, and you can neatly tuck it away in the corner of a room. The blinking LEDs in front indicate Power, Data In, Data Out, and WAN Status. There are numerous perforations on the side for ventilation, and there is no cause for it to get overheated.

Pros
  • Vertical form factor
  • Solid build quality
  • Stable at speeds above 100 Mbps for hours
Cons
  • No USB port
  • Single Ethernet port
  • DOCSIS 3.0
  • Downstream/Upstream: 4 x 4
  • Download/Upload Speed: 150 Mbps / 120 Mbps
  • Modem/Router Combo: No

With an off white chassis, the Netgear CMD31T looks delicate and quite classy. The package contained a stand, and you could place it horizontally or vertically.

The rear panel has an Ethernet port. We suggest you attach it to a router (you can choose a router that costs less than 100 dollars). There is also the coaxial cable internet input. There are several LED indicators in front, indicating Power, WAN Status, Upload, and Download. The last two can turn partly green and amber to show how many channels are in use.

Setting it up was a breeze. Just type in 192.168.100.1 and type in “admin” and “password” for logging in the first time. The configuration pages were auto-filled mostly, and there was little to select except the device name or SSID.

We downloaded several Ubuntu distro torrents (these are legal torrents hosted in high-speed servers) to install it on a few Ubuntu compatible laptops. The download speed was quite steady at above 150 Mbps.  The upload was also satisfactory and showed above 120 Mbps most of the time.

For a DOCSIS 3.0 modem with 4 x 4 channels, this is reasonably satisfactory. The circuit boards and connectors are quite well built, and the product will probably last several years, even with constant use. Our conclusion, a cheap, efficient workhorse that is ideal for homes using no more than 5 devices simultaneously.

Pros
  • Extremely affordable device
  • Time tested use with several different ISPs
  • Excellent ease of set up
Cons
  • Only one Ethernet port is restrictive
  • Lack of battery backup
