Slick Dealers don't rent from Xfinity. Slick Dealers buy a modem and router. Bite the bullet and buy. Don't rent.

I've been running one with zero downtime and consistently great speeds for 6 months now. Highly recommend this.

so based on arris's specs on its site, the s33 adds a 2.5g port and fancy new clothes.

for those that have a sb8200, i would say wait for docsis 3.2/4 unless you have to have higher than a 1 gig connection.
What will the advantages be of the newer Docsis standards? I have a 3.0 I've been itching to upgrade to this model in part bc of the additional ethernet port.

I don't think there's any advantage? I mean unless you have speeds over that of your current modem supports. And even then you need a WiFi 6 router to truly feel the effects?!

You will never get anything above 700-800 with just docsis 3.0

But with only a 2.5Gbps port how future proof will it be? Serious question.

I brought this the first month it came out, has been working flawlessly with RCN gigabyte internet.


I have the modem routed to pfsense and I am able to pull down 900mb-ish, and 450mb over wifi using TP-link omeda. Super happy with this setup, it never experienced interruptions.

Quote from yyz :
Seems like a decent price, but how would you compare this to the SB8200 [amazon.com] (currently $149 and also DOCSIS 3.1 32x8)?

I know not for my current speed, but I've been waiting to get any 3.1 modem and upgrade the speed I can get, but you know...covid and limited funds.

I have an older SB model that is working well. I don't really like the look of the round device and think it might get warm in the area I keep the modems (a mostly enclosed cabinet unit with just a USB fan moving air most of the time). I have been able to avoid heat issues with current modem and routers, but some routers have been hotter than others.

So just wondered if really worth it for the S33 or for $20 less to get the SB8200.

Thanks OP for posting! Thanks for any feedback others can offer.
8200 has like 7 different revisions and only some are supported on certain ISPs. The S33 is the no-brainer choice for compatibility.

The 8200 has a spectrum analyzer function that the S33 doesn't have but the thing is so damn stable it doesn't need it really.

Confirmed. I traded my old non working Netgear Modem today, received the 15% coupon and used my $25 rewards. Out the door total was $108.xX

At near price parity, I'd go with the S33. (Future proofing, compatibility, etc.) $20 is nothing spread out of the 5+ year lifespan of a modem. There was a recent deal for Amazon Warehouse SB8200 units for $66.76, which made my decision much easier.

Quote from GreenKite4385 :
I have the the traditional rental from xfinity and don't even need a router because it already has WiFi and 4 Ethernet ports. I guess it depends what you need a router for.
Indeed. Some people like to separate the modem so they aren't stuck paying rental fees and can upgrade modem and router/switch/access point(s) individually. Each technology progresses at a different pace.


Quote from GreenKite4385 :
Edit: this is not the one you want unless your willing to buy a separate router. This does not have Ethernet plugs probably doesn't have WiFi either
It has Ethernet ports, just no routing/switching capabilities, so you will still need a router, switch, and access point(s), whether that is three separate units, or some combo unit.

Most MB only have a single gigabit port. Also 2.5 - 10GBE are still not in common use yet and in expensive routing hardware.

I think the even more limiting factor right now is actually finding an ISP to supply a >1Gbs connection.

That said, this modem does offer some future proofing, and 2.5/5/10GigE hardware is definitely becoming cheaper and more mainstream every day:
MikroTik now has a 4-port 10GbE switch for under $150, and a 10GbE router for under $200.
QNAP has a 2.5GbE switch for under $120
TP-Link has an all-in-one wireless router for under $200, with a 2.5GbE port that can be configured for either LAN or WAN.
I picked up a L2 managed 52-port switch with 4x 10GbE uplink ports for less than $300, and that was probably 5+ years ago.

Have not seen ANY wifi routers with even 2.5GBE for under $200
