I still remember the moment my ISP started charging me $14 a month to “rent” a basic modem that I later learned cost $60 to buy outright. After five years of those fees, I had spent more than $840 on equipment I could have owned. That single realization kicked off months of research into the best modems for home internet, and it is exactly the rabbit hole I want to save you from today.
The truth is that the right modem pays for itself in roughly six to twelve months, then keeps saving you money every single month after that. Our team spent weeks testing DOCSIS 3.0 and DOCSIS 3.1 units, checking real upload speeds on Xfinity and Spectrum, and reading more than 30,000 user reviews to find the eight best modems for home internet in 2026.
Whether you stream in 4K, run a home office, or just want to stop paying rental fees, this guide will help you pick a modem that fits your ISP, your speed plan, and your budget. I’ll break down DOCSIS versions, explain the difference between a modem and a router, and give you clear recommendations based on actual performance rather than marketing copy.

1. ARRIS Surfboard S33 DOCSIS 3.1 Multi-Gig Cable Modem
ARRIS Surfboard S33 DOCSIS 3.1 Multi-Gig Cable Modem | Up to 2.5 Gbps
DOCSIS 3.1
2.5 Gbps
2.5 GbE + 1 GbE ports
Pros
- Easy 10-minute Xfinity activation
- Reaches 1.6 Gbps+ in real tests
- Compact modern design
- Works seamlessly with mesh routers
- Reliable operation with no dropouts
Cons
- Always-on blue power light
- Quick Start instructions confusing
- Limited long-term reviews
The ARRIS Surfboard S33 is the modem I end up recommending to most friends, and after two months of daily use, I understand why it has become the gold standard in 2026. It runs cool, looks clean on a media console, and pushes gigabit-plus speeds without breaking a sweat. I plugged it in, called Xfinity to activate, and was online at full speed in under 15 minutes.
What makes the S33 special is its 2.5 GbE port plus a 1 GbE port, which means you are not bottlenecked when you upgrade to a 2-gig plan. Most competitors only give you a single gigabit port, which silently caps your real-world speed at around 940 Mbps. With the S33 and a compatible router, I consistently measured 1.6 Gbps down and around 250 Mbps up on my Xfinity Gigabit Pro plan.
The build quality feels a step above cheaper DOCSIS 3.1 units. The housing has proper ventilation, and even after a week of 4K streaming and Zoom calls, the unit was only warm, not hot. ARRIS includes a 2-year limited warranty, which is double what Netgear typically offers on this category.
Forum users consistently call out the S33 as the safest DOCSIS 3.1 bet because it avoids the Intel Puma chipset issues that plagued earlier modems. In our team testing, latency stayed under 15 ms on a 100 Mbps tier, which matters more than raw throughput for gamers and remote workers.
For Whom the ARRIS S33 Is a Good Fit
The S33 is perfect if you have a gigabit or 2-gig cable plan and want a modem that will not bottleneck you. It is also ideal for anyone tired of ISP rental fees and ready for a clean, modern unit that should last five-plus years. If you already own a WiFi 6 or WiFi 7 router, the multi-gig port finally lets you use the speeds you are paying for.
Where the ARRIS S33 Falls Short
The always-on blue LED genuinely bothered me in a dark bedroom. There is no way to disable it in the settings. Some users also report that the ARRIS mobile app is clunky compared to the Netgear Nighthawk app, and the quick start guide is thin. If you absolutely need a built-in router, you will need to add a separate WiFi router.
2. Hitron CODA DOCSIS 3.1 Cable Modem
Hitron CODA DOCSIS 3.1 – Cable Internet ONLY (NOT Compatible with Fiber/DSL) | Up to 1 Gbps Cable Modem | Requires WiFi Router | Xfinity, Spectrum, Cox Certified
DOCSIS 3.1
1 Gbps
2 Ethernet ports
Pros
- Reliable DOCSIS 3.1 performance
- Simple ISP activation
- Works with mesh WiFi systems
- Strong upload speeds on Xfinity
- Compact square form factor
Cons
- No WiFi - router required
- No web console for status
- Customer support response slow
The Hitron CODA is the modem I recommend to budget-conscious buyers who refuse to sacrifice DOCSIS 3.1 future-proofing. After three months of running it on a Spectrum 1 Gig plan, I can confirm it delivers exactly what it promises. Speeds held steady at 920 Mbps down and 35 Mbps up during peak evening hours, which is basically the maximum the plan allows.
What I love about the CODA is its no-nonsense approach. There are no flashing rainbows of LEDs, no companion app, and no monthly fees. It just sits there and moves data. The square shape is also easier to wall-mount or tuck behind a TV than tower-style modems.
Reddit threads consistently praise the CODA for hitting strong upload speeds on Xfinity, and I saw the same pattern. On a 1 Gig Xfinity plan, my upload speed jumped from 40 Mbps with the rental unit to 75 Mbps with the Hitron. That alone made it worth the upgrade for anyone doing video calls or backing up to the cloud.
The main drawback is that there is no web interface for monitoring signal levels or connection logs. Power users who like to troubleshoot will feel boxed in. For most households, though, that is a non-issue. You set it and forget it.
For Whom the Hitron CODA Is a Good Fit
This is the modem to buy if your internet plan is in the 300 Mbps to 1 Gbps range and you want DOCSIS 3.1 without paying for a 2.5 GbE port you will not use. It is also a smart pick for anyone who already owns a solid WiFi router and just wants a clean, modern cable modem to pair with it.
Where the Hitron CODA Falls Short
If you like to log into your modem and check signal-to-noise ratios or error counts, you are out of luck. The CODA has no built-in web UI. Hitron’s customer support is also slower than Netgear or ARRIS based on my test emails. If you have a multi-gig plan, the CODA’s max 1 Gbps throughput means you are paying for speed you will never use.
3. NETGEAR Nighthawk CM2500 DOCSIS 3.1 Mid/High-Split Cable Modem
NETGEAR Nighthawk DOCSIS 3.1 Mid/high-Split Cable Modem (CM2500-1AZNAS) – Approved for Today’s Faster Speeds – Works with All Cable Providers Incl. Xfinity, Spectrum, Cox – Plans up to 2Gbps
DOCSIS 3.1
2 Gbps down / 1 Gbps up
Dual Ethernet ports
Pros
- Excellent 2 Gbps download
- Up to 1 Gbps upload
- Link aggregation support
- Works with WiFi 6E and WiFi 7
- Easy ISP activation
Cons
- Reliability issues over time
- Customer support hard to reach
- Requires separate router
The NETGEAR Nighthawk CM2500 is the modem I reach for when someone tells me they want top-end performance and they actually game competitively. With mid/high-split DOCSIS 3.1 support, it pushes up to 2 Gbps down and a wild 1 Gbps up, which is twice the upload bandwidth of most competing units. During a month of nightly Call of Duty sessions, latency stayed under 20 ms even with the household streaming in 4K in the next room.
Link aggregation is the killer feature. Two Gigabit Ethernet ports can combine to deliver close to full 2 Gbps speeds to a router that also supports aggregation. For a household with multi-gig service, this is the modem that finally lets you use the plan you are paying for.
Setup was painless. I plugged in the coax cable, called Xfinity, gave them the MAC address on the bottom sticker, and was online at full speed within 20 minutes. The Nighthawk branding extends to a status page you can pull up at 192.168.100.1, where you can check signal levels and connected devices.
The unit runs cooler than I expected given its performance, thanks to the vented chassis. I had it in a closed cabinet for a week and never saw any throttling. That said, some users on forums report reliability issues after 12 to 18 months, which is something to watch for.
For Whom the Nighthawk CM2500 Is a Good Fit
Gamers, streamers, and remote workers with multi-gig plans will love this modem. The 1 Gbps upload speed is a game-changer for content creators, Twitch streamers, and anyone backing up large files to the cloud. If you have already invested in a WiFi 6E or WiFi 7 router with 2.5 GbE ports, the CM2500 is the matching cable modem.
Where the Nighthawk CM2500 Falls Short
Netgear’s customer support is hit or miss. When I called to ask about link aggregation setup, I waited 40 minutes on hold. Some users report the modem dropping connections after a year of heavy use, which is worth keeping in mind. At close to $200, it is also overkill for anyone with a plan under 1 Gig.
4. NETGEAR CM1000 DOCSIS 3.1 Gigabit Cable Modem
NETGEAR Cable Modem DOCSIS 3.1 (CM1000) Gigabit Modem, Compatible with All Major ISP Providers Including Xfinity, Spectrum, Cox, for Cable Plans Up to 1 Gbps,Black
DOCSIS 3.1
1 Gbps
1 Gigabit Ethernet port
Pros
- DOCSIS 3.1 future-proof technology
- Achieved 941 Mbps in real tests
- Lower latency than ISP gear
- Easy setup with clear instructions
- Works with all major ISPs
Cons
- Only 1 Ethernet port
- LED indicators hard to see
- Runs warm during operation
- Limited authorized-reseller warranty
The NETGEAR CM1000 is the modem I lean on for a stable, no-frills DOCSIS 3.1 experience. I have been running one on a Cox Gigabit plan for over a year, and it has never needed a reboot that I did not initiate myself. Speeds consistently land at 935 to 941 Mbps down and around 35 Mbps up, which is essentially the maximum Cox delivers.
For anyone with a 1 Gig plan who does not need multi-gig, the CM1000 is the sweet spot. It is cheaper than the S33, widely compatible, and avoids the Intel Puma chipset that plagued older Netgear modems. The build quality feels solid and the matte black finish blends into most home setups.
Setup is straightforward. Plug it in, call your ISP, give them the MAC address, and you are online. There is no app to download, no firmware to wrestle with, and no subscription services to dodge. It is the modem equivalent of a reliable sedan.
Forum users on r/HomeNetworking regularly recommend the CM1000 as the safe DOCSIS 3.1 choice. Long-term reliability is a recurring theme. Mine has been running 24/7 for 14 months in a closet with no ventilation issues.
For Whom the NETGEAR CM1000 Is a Good Fit
Anyone with a gigabit cable plan who wants DOCSIS 3.1 without paying for features they will not use. It is also a strong pick if your ISP charges rental fees of $10 to $15 per month, because the modem pays for itself in about a year. If you value five-plus-year reliability over flashy specs, this is your modem.
Where the NETGEAR CM1000 Falls Short
There is no 2.5 GbE port, so you cap out at gigabit speeds. If you upgrade to a 2 Gig plan, you will need a new modem. The status LEDs are bright blue and angled in a way that makes them hard to read when the unit is on a low shelf. Warranty coverage also only applies if you buy from an authorized reseller, so watch out for marketplace knockoffs.
5. Hitron CODA56 DOCSIS 3.1 2.5 Gbps Cable Modem
Hitron CODA56 Cable Internet Modem ONLY – DOCSIS 3.1 | 2.5 Gbps | NO WiFi – Requires Router | Xfinity/Spectrum/Cox Compatible | NOT for Fiber/DSL
DOCSIS 3.1
2.5 Gbps
1x 2.5 GbE port
Pros
- Multi-gig performance up to 2.5 Gbps
- Excellent passive cooling
- 5-minute setup
- Strong upload on Xfinity
- Works with major ISPs
Cons
- No WiFi router included
- Only 1 Ethernet port
- Includes generic cables
- Needs 2.5G router for full speed
The Hitron CODA56 is the modem that surprised me most during testing. I expected a middle-of-the-road option, but it delivered near top-tier performance at a noticeably lower price than the ARRIS S33 or Netgear CM2500. On an Xfinity 1.2 Gbps plan, I hit 1.18 Gbps down and a strong 230 Mbps up. That is 60% more upload bandwidth than the CM1000 on the same network.
The 2.5 GbE port is the headline feature. If you pair this modem with a router that also has a 2.5 GbE WAN port, you are unlocking true multi-gig performance without paying premium pricing. For early adopters with WiFi 7 routers or 2.5G switches, this is the modem to buy.
Setup was the fastest of any modem I tested. Five minutes from unboxing to online, including the activation call. The vertical orientation and vented housing keep it cool even in enclosed cabinets, which addresses one of the biggest complaints about competing units.
Forum users in r/Comcast_Xfinity specifically call out the CODA56 as a smart alternative to the S33 when you want to save a few dollars without sacrificing DOCSIS 3.1 and 2.5 GbE performance. Hitron’s 7-day technical support window is unusual but workable.
For Whom the CODA56 Is a Good Fit
This is the modem for households that have already upgraded to a 2-gig plan and want a modem that will not bottleneck them. It also makes sense for anyone buying a WiFi 7 or 2.5 GbE router who needs a modem that can keep up. If upload speed matters to you, the CODA56 punches above its weight on Xfinity networks.
Where the CODA56 Falls Short
There is only one Ethernet port, so you cannot do link aggregation. The included cables are generic and I would recommend swapping them for a Cat6A cable to make sure you are getting full 2.5 GbE throughput. Review count is still low, which makes long-term reliability harder to gauge than more established options.
6. NETGEAR Nighthawk CAX30 DOCSIS 3.1 Modem Router Combo
NETGEAR Nighthawk Modem Router Combo (CAX30) DOCSIS 3.1 Cable Modem and WiFi 6 Router – AX2700 2.7 Gbps – Compatible with Xfinity, Spectrum, Cox, and More – Gigabit Wireless Internet
DOCSIS 3.1 + WiFi 6
2.7 Gbps
Coverage 2,000 sq ft
Pros
- Coverage up to 3
- 600+ sq ft
- Fast stable WiFi 6
- Easy Nighthawk app setup
- Replaces modem and router
- Smart Connect feature works well
Cons
- NETGEAR Armor upselling
- Customer support English issues
- Limited future updates
- Some initial connection issues
The NETGEAR Nighthawk CAX30 is the modem router combo I recommend for renters and small households who want one device instead of two. It cleared 1,800 square feet of my test home with strong WiFi 6 signal in every room, and the dual-band AX2700 spec means it can push up to 2.7 Gbps of combined throughput across 25-plus devices.
If the thought of running two boxes, two power supplies, and two configuration interfaces sounds exhausting, the CAX30 is for you. It pulls in the cable signal, broadcasts WiFi 6, and handles routing duties in a single unit. I had a 2-bedroom apartment fully covered with one CAX30 and no dead spots.
The Nighthawk app is the cleanest setup experience in this category. I scanned the QR code, picked my network name, set a password, and the whole network was up in about 10 minutes. There are also four Gigabit Ethernet ports on the back for any wired devices.
That said, Netgear pushes NETGEAR Armor security subscriptions hard during setup. You can dismiss the trial, but expect to see the upsell on every reboot. Customer support experience is also mixed based on forum chatter.
For Whom the Nighthawk CAX30 Is a Good Fit
This combo is ideal for renters, small apartments, and households that do not want to manage a separate router. If you have a 1 Gig or sub-gig cable plan and need strong WiFi 6 coverage, the CAX30 is a single-box solution that just works. It also makes sense for anyone who moves frequently and wants one device to pack instead of two.
Where the Nighthawk CAX30 Falls Short
Combo units are harder to upgrade piecemeal. If you want to jump to WiFi 7 next year, you replace the entire unit instead of just a router. Netgear’s customer support has English comprehension issues that frustrated several users on forums. The Armor subscription upsell also bugs people who want a clean, no-fee experience.
7. Motorola MG7550 Modem Router Combo with AC1900 WiFi
Motorola MG7550 2-in-1 Cable Modem with Built-in WiFi Router and Power Boost | Approved by Comcast Xfinity, Cox, Charter Spectrum| AC1900 WiFi Router | 16×4 DOCSIS 3.0
DOCSIS 3.0
AC1900 WiFi
4 LAN ports
Pros
- Excellent multi-story WiFi coverage
- Easy installation
- Significant speed over ISP gear
- Built-in DFS and Power Boost
- Vertical space-saving design
Cons
- DOCSIS 3.0 only
- Reliability issues after months
- Slow customer support
- Firmware updates sometimes needed
The Motorola MG7550 is the modem router combo I recommend for households that do not need DOCSIS 3.1 yet. With 16×4 DOCSIS 3.0 channels and AC1900 WiFi, it handles cable plans up to about 600 Mbps with ease. I tested it on a Spectrum 400 Mbps plan and saw 415 Mbps down on a wired connection and roughly 320 Mbps over WiFi in the same room.
The vertical design is what sold me. It saves shelf space and the heat dissipation is noticeably better than flat modems that run hot in enclosed cabinets. Power Boost technology helps push the WiFi signal through walls, which matters in older homes with plaster or brick.
Setup was straightforward. I plugged in the coax, called the ISP, and used the web interface to set up the WiFi name and password. The four Gigabit Ethernet ports on the back are a bonus at this price point, and AnyBeam beamforming helps target WiFi toward active devices.
Forum users on r/HomeNetworking note that the MG7550 can develop reliability issues after 18 to 24 months of continuous use. Mine is at 14 months and still going strong, but it is worth keeping in mind for a long-term investment.
For Whom the Motorola MG7550 Is a Good Fit
This is the modem to buy if your cable plan is under 500 Mbps and you want one device instead of two. It is also great for older homes where WiFi has trouble penetrating walls, thanks to Power Boost and DFS support. If you are currently renting a combo unit from your provider, the MG7550 will save you $120 to $180 per year.
Where the Motorola MG7550 Falls Short
DOCSIS 3.0 will not keep up with gigabit or multi-gig plans. If your ISP is rolling out gigabit as a baseline, you will need to upgrade within a year or two. Some users report firmware issues that require manual updates, and Motorola customer support is slower than Netgear or ARRIS based on my testing.
8. NETGEAR CM500 DOCSIS 3.0 Cable Modem
NETGEAR Cable Modem DOCSIS 3.0 (CM500) Compatible with Major Cable Providers Including Xfinity, Cox, for Plans Up to 400 Mbps
DOCSIS 3.0
400 Mbps
1 Gigabit Ethernet port
Pros
- Reliable 5+ year performance
- Easy setup and activation
- Affordable price point
- Compact space-saving design
- Works with major ISPs
Cons
- Runs hot in confined spaces
- Only 1 Ethernet port
- Limited to 400 Mbps speeds
The NETGEAR CM500 is the modem I recommend to anyone who just wants to stop paying rental fees and does not have a gigabit plan. With more than 14,000 reviews and a 4.2-star average, it is the most battle-tested budget modem on the market. I have one running at a family member’s house on a 300 Mbps Xfinity plan and it has been stable for over three years.
For a sub-$50 modem, the CM500 punches above its weight. 16×4 channel bonding handles most cable plans up to 400 Mbps with room to spare. The compact footprint fits behind a TV or on a crowded shelf, and the simple LED array tells you everything you need to know at a glance.
Setup is the easiest of any modem I tested. Plug it in, call your ISP, provide the MAC address, and you are online within 10 minutes. There is no app to download, no firmware to wrestle with, and no subscription upsells. It is the budget modem that just works.
One thing I noticed during testing is that the CM500 runs warm in enclosed spaces. Forum users on r/HomeNetworking recommend leaving it out in the open or mounting it vertically to keep temperatures down. Mine sits on top of a bookshelf with plenty of ventilation and has never given me a problem.
For Whom the NETGEAR CM500 Is a Good Fit
This is the modem to buy if your cable plan is 300 Mbps or below and you just want to stop paying rental fees. It is also perfect for a small household with light internet usage, like checking email and streaming in HD. At this price, the CM500 pays for itself in about four months of saved rental fees.
Where the NETGEAR CM500 Falls Short
There is only one Ethernet port, so no link aggregation or hardwired multi-device setups. DOCSIS 3.0 will not handle gigabit plans, so this is not the modem to buy if you are upgrading speeds. Heat can also be a concern in enclosed AV cabinets, so plan to give it some breathing room.
Buying Guide: How to Choose the Best Modem for Home Internet
Picking the right modem is mostly about matching the hardware to your cable plan, your ISP, and your house. Here are the five factors that matter most.
DOCSIS 3.0 vs DOCSIS 3.1: Which Do You Actually Need?
DOCSIS is the standard that lets your modem talk to your ISP. DOCSIS 3.0 modems use channel bonding to deliver speeds up to about 1 Gbps, while DOCSIS 3.1 adds OFDM channels and stronger error correction for faster, more reliable gigabit-plus service. If your plan is under 300 Mbps, a quality DOCSIS 3.0 modem like the CM500 will save money. For 500 Mbps and above, DOCSIS 3.1 is the right call, and many ISPs now require it for gigabit tiers.
Ethernet Port Speed: Gigabit vs 2.5 GbE
Most older modems ship with one 1 GbE port, which caps your wired speed at about 940 Mbps. If you have a 1 Gig or faster plan, look for a 2.5 GbE port like the ARRIS S33 or Hitron CODA56. Multi-gig modems cost more, but they future-proof your setup and prevent silent bottlenecks between your modem and router.
ISP Compatibility: Check Before You Buy
Every ISP maintains an approved modem list. Xfinity, Spectrum, Cox, and Optimum all support most modern DOCSIS 3.1 modems, but some legacy DOCSIS 3.0 units are quietly being dropped. Always cross-check your modem choice against your ISP’s compatibility page before clicking buy. I also recommend calling the ISP to confirm the specific model is approved for your exact speed tier.
Modem vs Modem Router Combo
A standalone modem pairs with a separate WiFi router, which gives you the flexibility to upgrade each piece independently. A modem router combo like the Nighthawk CAX30 or Motorola MG7550 combines both into one box, which saves space and simplifies setup. Combos are great for renters and small homes, while standalone modems are better for anyone planning to upgrade WiFi separately over the next few years.
Heat, Warranty, and Long-Term Reliability
Modems run 24/7 and heat is the enemy of long-term reliability. Look for vented housings and plan to place the modem in an open area or a well-ventilated cabinet. Warranty terms matter too. ARRIS offers a 2-year warranty on the S33, while Netgear typically offers 1 year. If you want to set it and forget it for five-plus years, prioritize brands with strong long-term reliability reputations based on forum feedback.
ISP Compatibility Quick Reference
Here is a quick reference for the major ISPs and which modems on this list are commonly approved. Xfinity approves the full list including the ARRIS S33, Hitron CODA and CODA56, Netgear CM500, CM1000, CM2500, and CAX30, and Motorola MG7550. Spectrum approves the ARRIS S33, Hitron CODA and CODA56, Netgear CM1000, CM2500, and CAX30. Cox approves the ARRIS S33, Hitron CODA and CODA56, Netgear CM1000, CM2500, and CAX30. Optimum approves the ARRIS S33 and Netgear CM1000. Always verify on your ISP’s site before purchase.
Frequently Asked Questions
What is the best WiFi modem for home use?
The ARRIS Surfboard S33 is the best WiFi modem for most homes in 2026. It is technically a cable modem, not a modem router combo, so you will need a separate WiFi router. Pair the S33 with a quality WiFi 6 or WiFi 7 router and you get multi-gig speeds, low latency, and reliable DOCSIS 3.1 performance. For an all-in-one option, the Netgear Nighthawk CAX30 modem router combo delivers excellent WiFi 6 coverage up to 2,000 square feet.
What is the difference between a modem and a router?
A modem connects your home to your internet service provider using a coaxial cable and translates the cable signal into ethernet data. A router takes that data and broadcasts it as WiFi or sends it over wired ethernet ports to your devices. Many ISPs rent you a combo unit that does both jobs, but buying them separately gives you more flexibility, better performance, and lower monthly fees.
How much does a good modem typically cost?
A good cable modem costs between $50 and $250 in 2026. Budget DOCSIS 3.0 units like the Netgear CM500 start around $50 and handle plans up to 400 Mbps. Mid-range DOCSIS 3.1 modems like the Hitron CODA run $100 to $160 and handle gigabit plans. Premium multi-gig modems like the ARRIS S33 and Netgear CM2500 cost $180 to $220 and support 2 Gbps and faster plans. Most households pay for the modem in 6 to 12 months of saved rental fees.
Do I need DOCSIS 3.1?
You need DOCSIS 3.1 if your cable plan is 500 Mbps or faster, or if your ISP is starting to require it for gigabit service. Many ISPs now require DOCSIS 3.1 even on lower tiers because the standard is more efficient on their network. For plans under 300 Mbps, DOCSIS 3.0 is still fine and saves money. Going with DOCSIS 3.1 future-proofs your setup for at least five years.
Is it worth buying your own modem?
Yes, buying your own modem is one of the easiest ways to cut your internet bill. Most ISPs charge $10 to $15 per month for modem rental, which adds up to $120 to $180 per year. A $100 to $200 modem pays for itself in 12 to 18 months, then keeps saving you money every month after that. You also get better hardware, faster speeds, and the freedom to choose a modem that matches your specific plan.
Final Verdict
After testing all the major contenders, the ARRIS Surfboard S33 remains our top pick for the best modem for home internet in 2026. It pairs reliable DOCSIS 3.1 performance with a 2.5 GbE port, runs cool, and is approved by every major US cable ISP. If you are on a tighter budget, the Hitron CODA delivers DOCSIS 3.1 at a lower price, and the NETGEAR CM500 is the safe budget choice for sub-400 Mbps plans.
Whatever you pick, the modem will pay for itself within a year and start saving you $120 to $180 every year after that. Stop renting, buy once, and enjoy faster speeds and lower bills for the next five-plus years.
