From my understanding XFinity/Comcast has been increasing upload speeds in some areas. If you got an email it probably means your area. For increased upload speed you need an OFDMA compatible device like the CODA56. S33 will currently not work if you want increased upload speeds.

List of devices compatible with "Next Gen Speed Tier". [xfinity.com] Again, this only applies if you got an email about increased upload speeds

Edit: If you don't mind 35mbps upload cap or you're not on a plan that would even get you enhanced upload speeds this modem still works great for Xfinity/Comcast.
I have this modem but Comcast keep emailing me to upgrade modem. I have 1ghz plan.
You shouldn't be getting charged for those tech visits. Ask for a supervisor if you're dealing with someone over the phone.

250mbps on a 1gbps plan is a line issue, not a modem issue. Likely a splitter or cable run that has gone bad. they should be able to see signal at the tap and node without having to visit your house first. If all of those are fine, then you should be testing speeds AT THE MODEM. Not your PC or anything post modem, at your modem. That's all they have to supply. Anything past that is your responsibility.

Don't use Xfinify if you care uploading speed, the hotspot from T-Mobile and Verizon 5G is much faster.

Bought this from Best Buy about 2 weeks ago. $156 less 15% (with their recycle program). Approximately $133 plus tax. I have Comcast also. No emails. No problem setting up. I am not a fan of Comcast either.

I hate to make another me too post, but I have had this modem for close to three years after upgrading to the gigabit service from Xfinity. I don't come close to get 1gb down (usually around 250mb). I have had several of their techs out and they blame the slow speed on everything non-Xfinity (PC, modem, cables, ethernet card, etc.). They have not been able to get me the speed I pay for and their tech visits which are a joke cost $75 each. I am currently trying the Tmobile $50/mo 5G internet and it is really hit or miss. At least Xfinity has been steady for me with no disconnects, etc. Slow, but steady.

Back on topic, I tried both this modem and the SB 8200 as they were about the same price at the time and this was faster for me.

Does this have range to cover 3500sf ? I might be over my head but still thought to ask here
it's only the modem. You will need your own wifi/router to connect to it.

It can cover as much range as your access point will allow.

I've had the SB8200 for a couple years and think it is starting to overheat. Do you think the S33 is worth the upgrade?

Bought this modem 2 months ago. Regularly getting 1300 Mbps download and 40 Mbps upload over Ethernet on our 1200/35 Xfinity plan. No issues so far.
Note: To pull speeds over 1000 Mbps, the router and switch need to support multi-gigabit speeds as well.

Same here, though they keep wanting me to get their modem/router combo and pay a monthly fee instead

Worth the upgrade. I went from an SB8200 to this S33 and it has been much more stable

When I bought the S33 one of the negatives I was reading about was that it tended to overheat. I have been running mine 24/7 for nearly 3 years and I have not seen that. It is warm, but I would not say hot to the touch. Again, it just hasn't failed me at all during this time. Also, its form factor is smaller and it fits better in the space I have available. Again, some complain about the bright blue light on the front, but it doesn't bother me. I think I paid close to $170 for it (a few dollars more than the SB8200) so this is a very good price I think.

Having said that, if your SB 8200 is running well and the perceived overheating is not giving you a problem, I would say save your money as in my limited testing I found them to be very similar performance wise. I kept my SB 8200 to be used as a backup, but I have not taken it out of the box since I started using the S33
