Asked 4 years ago by LSMorgan.

• A:Answer The only difference between the S33 and SB8200 is the presence of a 2.5Gbps ethernet port on the S33 modem (hence S33 is a future proof modem and would work with multi-gig speed tier subscription from your service provider)

Q: QuestionDoes this modem update software automatically or it needs to update software manually.

Asked 3 years ago by Slduo.

• A:Answer Updates are automatic and cannot be done manually. The Cable Operators (MSOs) have complete control of what cable modem/gateway hardware they will allow installed and the firmware it uses, on their cable plant. This means anything directly connected to the cable plant (COAX) in your house. They do this to ensure that nothing happens to anyone upstream from your connections. Cable Operators follow the DOCSIS Specifications that control this methodology of firmware upgrades as well as providing security for the firmware upgrades. Cable Operators also run both the products and firmware through their own test cycles to approve any manufacturers’ modems, wireless gateways, and the associated firmware updates for deployment. This is not an ARRIS only implementation, but the required implementation of any cable device manufacturer. After an MSO has tested and approved a new version of firmware for a cable device, they will then “push” that new firmware out to the devices.

Q: QuestionDoes this modem work with Xfinity provider? Can this replace my rental xfinity modem xFi Gateway 98GSGE01XB748638?

Asked 4 years ago by Anonymous.

• A:Answer Check compatible devices at https://www.xfinity.com/support/devices/. The S33 is listed as a supported device. It's modem only, so it doesn't replace the gateway that includes a wifi router.

Q: QuestionDoes it have built in Wifi? If yes what 802.11 specifications does it support. And what’s the throughput?

Asked 4 years ago by Khan.

• A:Answer No, S33 does not have an inbuilt Wi-Fi router (it is a cable modem only), you would need a separate wifi system to avail the wireless functionality. S33 is capable of supporting a maximum throughput of 3.5 Gbps (one 2.5Gbps port + one 1 Gbps port). Note that in order to utilize the 2 ethernet ports simultaneously, you would need to have subscription to an additional IP address form your service provider

Q: QuestionThere are no instructions, please provide on how to install

Asked 3 years ago by Instructions.

• A:Answer There are real instructions, past the enclosed quick-start guide, but you must download them. If you're on Comcast/Xfinity, they will need to be contacted for provisioning, and they must upload a bootloader file. If you use the 2.5 GB port on the back, and that port isn't working, it's because the person on the phone uploaded the wrong bootloader... they were trying,but really didn't have a clue. Hope this helps.

Q: QuestionUnless I am reading this wrong the specs show Downstream Data Speed = 5000 Mbps Upstream Data Speed = 2000 Mbps Wired Speed = 2500 Mbps. if it can't move data to another device faster than 2500Mbps that means it is effectively capped at that speed right?

Asked 3 years ago by Nixter.

• A:Answer The 2.5Gbps speed is due to the 2.5Gb port available on this product. The speed of the device is rated for higher than 1Gbps plans by service providers. The download and upload speed is based on the service tier with your service provider, but DOCSIS 3.1 (as supported by this product) supports higher download and upload speeds.
