With a 2.5 Gbps Ethernet port plus an additional 1 Gbps Ethernet port it's capable of combined download speeds up to 3.5 Gbps. The S33 is the fastest modem in the SURFboard lineup delivering the fastest speeds and the latest technology without the premium rental cost.

Review: This is my second time buying the ARRIS S33 DOCSIS 3.1 multi-gigabit cable modem—because lightning apparently decided my internet setup was too good and struck down my first one like Zeus himself was having a bad day. RIP, my beloved modem, you lasted just long enough to show me what true speed feels like before being vaporized in a flash. But honestly? I’m not mad. The ARRIS S33 is a beast. It supports DOCSIS 3.1, meaning it’s ready for the next-generation high-speed cable internet—like, up to 2 Gbps downstream and 1 Gbps upstream (if your ISP and plan are playing along). It’s also backwards compatible with DOCSIS 3.0, so if your ISP hasn’t fully upgraded yet, no worries. Installation is impressively painless. Plug and play, with support for IPv4 and IPv6, and it handles channel bonding like a champ—aggregating multiple channels to maximize throughput and minimize lag. I’ve thrown all kinds of traffic at it: 4K Netflix, intense online gaming sessions, video calls where my face looks mostly presentable, and it doesn’t even break a sweat. The only caveat: lightning doesn’t play nice with electronics. So if you live somewhere prone to storms like me, consider a surge protector or UPS, unless you want to keep buying backup modems like this is a weird hobby. Bottom line: the ARRIS S33 is fast, reliable, and future-proof enough to handle whatever Comcast Xfinity throws at it. Just pray to the weather gods to keep your modem alive.
Review: Nice modem to use with Xfinity if you don't want to use their modem. I have it hooked up to my Orbi Mesh Router and it works as it should work and connects easily to ORBI

## Questions & Answers

**Q: Can you use both ethernet ports at the exact same time?**
A: Depends on your ISP. The company I work for gives you 2 public IP addresses and you can get any combo of 2 computers, 1 computer and one router or 2 routers. You WILL NOT however get full speed on both at the same time but not half either. The modems we use now have only one ethernet port but if you hook up a simple switch you get both IPs through it. But ONLY 2.

**Q: Will this support xfinity extreme 1200mbps ? it's not on the supported device list.**
A: The Arris S33 is a DOCIS 3.1 capable device 32 x 8 rated for speeds up to 2.5 Gb. While the modem is indeed on Xfinity supported device list (check detailed discussions on dslreports.com), what matters is your router. Ensure you have a router capable of 1+Gb speeds.

**Q: Does this modem support snmp?**
A: NO.  I wish that wasn't the case, but we have no SNMP access.  No Arris home modems support user facing SNMP. The cable provider has management, but SNMP isn't exposed to the home network.    From Arris: "SNMP (Simple Network Management Protocol) is not supported in Motorola Home Networking products. SNMP is included in Motorola Cable Modem and Home Gateway products, but it is intended for use only by the Cable Provider. There is no direct access to SNMP MIBs for the end-user."

**Q: Is one port for the router and the other port can be used for hardwiring a device (computer, etc) directly to modem?**
A: The second port can only be used if connected to a separate/different IP. In other words, your ISP will have to give you 2 separate IPs. in order to use the second port.

### ⭐ Review
*by A***R on 4 January 2024*

This Arris Surfboard S33 modem runs extremely, extremely HOT 🔥🔥🔥! The coverage is sporadic and glitches out to my router all the time. My Asus router works fine. Arris has a problem with this modem overheating. It does not vent well. It desperately needs revisioning. Start over, do it right! Don't cheap out on your customer to save a few pennies. They keep your business in business. Heat sinks or an internal fan or both need to be implemented and utilized. A better case to allow for improved air flow should also be considered. Arris must know about this design flaw and be okay with it. The modem will just eventually burn itself out. Electronics will eventually break down by continuous heat and overheating. This is just hot to the touch, and it is unacceptable. I am very unhappy with this company and their modem. It could even possibly be a fire hazard. I give it a negative rating and negative stars. I do not endorse this hunk of junk by Arris. Choose another company. There are so many other better options available. Learn from my mistake. This is a terrible excuse for what a modem should be. Update 1-10-24 This is the most dismal, disappointing modem that I have ever owned constantly dropping the connection. This morning, I had no connection to the internet. I had to unplug everything. I thought maybe if I rebooted the modem and waited 30 minutes and then plugged it back in, it might help clear it. IT DID NOT! I'm getting abysmal download speeds of 2 and 3 mb/s. It finally, finally connected to my router and 2 and 3 mb download speeds is what I have. It did not want to connect. This is an expensive disaster and Arris should be ashamed of the absolute inferior quality product they are putting out to the public right now. Absolutely enraged! 🤬 I'll be returning this item. I hope nobody buys this as a used modem.
