Hey there! Let's break this down simply. You're using a Netgear N600 router and a Motorola Sb6121 modem, both of which are quite old. Your ISP charges 200 Mbps, but your modem only supports 172 Mbps. The router claims up to 300+300 Mbps, but that seems confusing.
If you stick with the current setup, the modem will act as a bottleneck since it can't deliver more than 172 Mbps. Even though the router promises higher speeds, it won’t help if your connection is limited by the modem. Upgrading either device would be better for smooth performance.
For a new build, consider a modern modem (like a 400+ Mbps model) and a router with at least 300 Mbps dual-band capability. This should avoid bottlenecks and make full use of your ISP’s speed. Stick to newer gear for the best results!
I recognize the constraints of my connection since it's limited by the modem. My performance will match the lowest quality available and align with the ISP's capabilities. For example, I can reach up to 200mbps from the ISP, but the actual speed is capped at 172mbps by the modem.
You're dealing with a basic 4x4 cable modem, the most affordable option available in the D3.0 range. You're aiming for something larger like 16x4 or 24x8. If you're on a budget, an 8x4 model might suffice, but it's better to opt for a higher-end unit for future upgrades. This isn't a mix-up. Most providers now use channel bonding, which lets them use multiple frequencies on the coaxial cable to boost data transfer. A 4x4 modem typically supports four downlink and four uplink channels. More channels mean faster speeds. Even if you have a more advanced modem than necessary, having extra channels helps manage network congestion. For example, if a channel gets busy, others can step in. Popular choices include the SB6183, CM500, and CM600. I own an SB6141, which on Comcast can reach up to 200 or 250 Mbps. I’ll stick with this model until we surpass the 200 Mbps tier or until Comcast removes it from service. If you’re willing to spend, a Docsis 3.1 modem is ideal—supports speeds up to 1 Gbps. ******Important******** Expect to find 32x8 Docsis 3.0 models, which match the specs of Docsis 3.1 units. Avoid buying a 32x8 Docsis 3.0; they use Intel Puma 6 chipsets and have known reliability problems. Arris once faced lawsuits over this chipset. For a 32x8 model, choose Docsis 3.1 instead. It’s the top-tier option. You can test your current router first, but Netgear and ASUS are generally recommended. Personally, I own a Synology RT2600AC—it performs well, though it costs around $200. If you’re considering an upgrade, plan accordingly. A new modem usually costs between $60 and $200, depending on features. Good routers typically range from $80 and up.
Your budget is likely around 200 USD, and you're looking for something that offers more than enough bandwidth to match your ISP's speed. If performance drops, you want it to be the internet service provider rather than your local hardware. The CM600 modem should handle speeds up to 960 Mbps comfortably. Since you have a cable connection instead of a phone line, I recommend a router that supports cable connections and meets your speed needs. For a 200 Mbps connection, consider models like the TP-Link AR200 or Netgear Nighthawk R7000, which are well-suited for stable performance.
I’m still figuring out what I need. I don’t quite grasp router speeds. Modems seem straightforward (your ISP offers 200Mbps, so get a modem that supports at least that, it’s clear and easy to follow). I just don’t know the right specs. The CM700 is listed on Amazon with download speeds up to 960Mbps, which is way beyond what my ISP gives. That should give room for growth, and any slowdown would likely come from the internet service provider. The AC1750 has a 1750 Combo speed, and the Nighthawk C7000 is compatible with several providers. The AC1900 modem is mentioned as well.
Question the advertised specs of modems. The Docsis standard works similarly to WiFi, but it doesn’t function as expected in real life. My 8x4 modem should handle more than 350 Mbps, yet Comcast caps it at 250 Mbps. The CM600 seems acceptable. No specific router suggestions since mine exceeds your budget. For brand choices, ASUS and Netgear are solid options locally. TpLink offers value but lacks advanced features. At minimum, opt for a device supporting AC wireless or WiFi 5.
Avoid using Docsis 3.0 with 32 channels. Intel has modified the Puma 6 chip, which causes problems. Check DSLreports.com for details. For 32 channels, switch to a Docsis 3.1 modem.
