Looking to buy a new modem and router package.
Looking to buy a new modem and router package.
I'm looking for a new router and modem, either as a single unit or two separate pieces, to ensure compatibility with Comcast's network. My requirements include specific LAN speed support, the ability to work on their network whether standalone or bundled, strong security features, port forwarding for gaming and streaming, traffic monitoring, DHCP reservation, dual-band Wi-Fi (2.4GHz and 5GHz), good channel coverage, and the flexibility to view other networks for better signal tuning. I also want options beyond just the essentials and am open to spending up to $400.
SB6183, CM500, CM600, compatible with any Docsis 3.1 modem. Avoid using 32-channel Docsis 3.0 modems.
It's the Arris brand. For your needs, consider a router that suits your requirements. Interestingly, your Arris Surfboard supports DOCSIS 3.0—though this feature isn't ideal for most users.
The issue isn't 3.0 itself, but the 32x8 3.0 modems that use the Intel Puma 6 chip. Understanding the shift from Docsis 3.0 to later versions is key—since Docsis 3.0 introduced channel bonding, configurations like 4x4, 8x4, 16x4, 24x8, and 32x8 became standard. More channels generally mean higher speeds. Having extra channels helps avoid problems during congestion. Be cautious with the speed numbers provided by manufacturers; while an 8x4 cable modem can reach over 300 Mbps, most providers cap it around 200-220 Mbps. You can find the exact channel setup needed on Comcast’s support page. If you want the best performance now, consider a Docsis 3.1 model, which supports up to 1 Gbps down and 45 Mbps up. Avoid 4x4 and 8x4 models—there are signs Comcast may phase them out eventually, so you might need to replace your modem. The recommended brands for routers are ARIS and Netgear, as they’re currently leading options. Router choice really depends on your internet speed needs, which most home routers can’t handle at Gigabit rates. Personally, I own a Synology RT2600 AC—it performs well but costs around $200.
The discussion about the channels might clarify your streaming problems on Twitch. Your usual connection speed is 11.0Mbps, but even after Comcast improved service in your area, issues persist with upstream speeds. You may need to wait or reset your router/modem. Also, does EOL stand for "End Of Life"? Since you purchased the router combo yourself, you didn’t have to rent it.
I wanted to check in about my previous message. Your reply is likely visible there. Appreciate it!
Comcast's upload speeds aren't great. Around 10 Mbps is typical for my region with a service under 1 Gbps. If you get Gigabit, it jumps to 45 Mbps. They seem to limit themselves to four upstream channels in most areas. Even with upgrades, if they stop supporting your plan, you're stuck upgrading again.
