When purchasing a router or modem, consider these tips for optimal performance and reliability.
I'm experiencing problems with my internet connection. Upgrading my equipment might help. Currently I have a modem from Arris 1602A, an Asus 68U plan with Optimum 300 (300 Mbps down, 35 Mbps up). I considered switching to the Arris SB8200 because it's Docsis 3.1 and offers more channels, which could improve stability and reduce congestion. My router is a Netgear X4S R7800. Any advice?
The setup won’t boost your stability. It mainly speeds things up with a Gigabit or faster connection. What challenges are you facing? Are you often needing to restart the router or modem? Have you checked for firmware updates on the device?
Interesting, what led you to say that? After checking the review on Wirecutter (https://thewirecutter.com/reviews/best-cable-modem/), specifically under "What about DOCSIS 3.1 and gigabit Internet?" (https://www.cablelabs.com/how-docsis-3-1...anagement/), they mention it does. My concern is the inconsistent internet performance—intermittent drops, packet loss, and T3/T4 errors on my modem. Along with occasional slow speeds, I suspect congestion might be the cause.
It seems the problem resolves itself after a short period without needing any manual fixes like rebooting devices. Updating the firmware isn’t necessary since mine is already current. The Puma 6 chip in my modem is present, but I’m not sure if that’s the issue. I’m also reaching out to my ISP to stay proactive, though.
The reason behind your latency spikes isn't necessarily the DOCSIS 3.0 modem you have. I still use an Arris brand device with a quicker connection and no problems. Many people experience similar situations. Your problem might stem from a defective modem, but we can't confirm that without testing. Latency problems can arise from any device due to various factors like poor cabling, faulty NIC, hardware faults, or interference. I suggest using an MTR tool (such as WinMTR on Windows) and running it against a service like Google. It will perform a continuous traceroute with packet loss and latency details, helping you identify the exact source of the issue.
Not completely correct. D3.1 doesn’t resolve all problems. Additional channel support might help. It’s like assuming some channels are bad while others work fine. Many recommend choosing a modem with more channels than necessary. This way, interference in just a few channels won’t cause major issues. Also, 32-channel D3.0 modems use the Puma 6 chip, which is known to have problems. In contrast, D3.1 models use the Broadcom chip, which tends to function better. If you own a Puma 6 modem, consider replacing it. Note that firmware updates are only available through your ISP, not the cable provider.
Sure, having additional channels can improve performance. Your current ISP supports DOCSIS 3.1, so the issue might be with your modem. The Arris SB8200 is a solid choice, while the Netgear Nighthawk CM1100 offers more flexibility. Consider what you need most for speed and reliability.
The simplest method to resolve channel problems is to review your signal page on the modem. Examine uncorrectable error counts. A small number is normal, but a high volume on one or more channels suggests a problem. Next, check which bands each channel operates on. This can sometimes reveal interference sources, such as broadcast TV, cellular signals, etc. From the modem, it seems all D3.1 models should function properly. Netgear and Arris are leading brands; I’d choose the more affordable option. For reference, I’m still using an SB6141 8x4 modem. I’ll wait for Comcast’s end-of-life support before purchasing a replacement.
What level of uncorrectable errors would be considered excessive? 100? 1000? I've attached a screenshot of my modem statistics from yesterday, taken right after the technicians completed their work, which is why the uptime and errors remain low.
10,000-100,000 could be a problem. I usually handle a few hundred without trouble. The power coming from upstream is a bit too high. Around 54-55 tends to cause big issues, though it seems okay overall.
