A:AnswerThe 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)
A:AnswerNo, 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
A:AnswerUpdates 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.
A:AnswerThere 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.
