    FAQS :

    Is this compatible with Xfinity Extreme 1200mbps? It isn't listed as a supported device.?

    ANSWER: The Arris S33 is a DOCIS 3.1 capable 32 x 8 device with rates of up to 2.5 Gb. While the modem is on the Xfinity approved equipment list (see for more information), it is your router that matters. Make sure you have a router that can handle speeds of at least 1 gigabit per second.

    Is it possible to utilise both ethernet ports at the same time?

    Answer: Update...... I got one from BestBuy, and YES, you can use both ports simultaneously. The 2.5 port is connected to my PC, while the other port is connected to my Asus Ax11000 router. I hope this information is useful.

    Will this modem fit on its side (1.75") in a 1RU rack space?

    Answer: Putting it on its side is probably not a smart idea. There are no vents on the sides. It's advisable to position it upright for heat dissipation. The sides of the Arris SB8200 have holes. With the modem laying horizontally in a 1U rack, the side holes will provide improved heat dissipation.

    Do all four Ethernet ports on this modem provide the same amount of bandwidth, or do some of them function at full capacity only?

    Answer: The rationale for a modem's four ports necessitates some explanation. It's critical to note that the MB8600 does not support routing. The MB8600 is merely a modem. Any of the MB8600's GigE ports may be used to connect a router. The link between the router and the modem may then use the full rate of Comcast's new DOCSIS 3.1 service, which is presently one gigabit per second. Comcast and other cable providers are anticipated to provide services faster than 1 Gbps in the future. When such quicker services are available, the MB8600's extra ports will be required. The MB8600's ports 1 and 2 may be joined together to give up to 2 Gbps. The MB8600's remaining two ports are for extra port bonding for rates more than 2 Gbps. When Comcast's service speeds exceed 1 Gbps, the router connected to the MB8600 must also perform port bonding in order to take use of the MB8600's port bonding. Port bonding is not supported by today's consumer routers. Port bonding is supported by several routers used in business networks. In the future, routers for households and small companies will be marketed with port bonding capabilities, allowing them to take advantage of future service rates greater than 1Gbps. In essence, the four ports on the MB8600 are there to let the MB8600 to give service rates greater than 1 Gbps WHEN THEY ARE AVAILABLE. That is an excellent design. Before you buy a modem that claims to give speeds beyond 1Gbps but lacks numerous ports that can be bonded, think carefully. Unless you have a mechanism to obtain the fast speed out of the modem, you won't be able to get a speed higher than 1 Gbps. The MB8600 is intended to give rates of up to 1 Gbps to a router with bonded GigE ports. Other modems aren't built as well.

    Is this powered by the now-famous Intel Puma 6 chipset?

    Answer: The MB8600 and other Motorola devices employ Broadcom chipsets, which are not affected by the Puma 6 chipset issue.

    Is it true that despite the multiple LAN ports, only one device can connect to the modem? You can't connect your computer and your router at the same time?

    Answer: The MB8600 supports just one device. You may use the MB8600 to connect your PC or to connect a router. If you pay for and receive several IP addresses from your provider, you can connect up to four devices directly to the MB8600.

    I'll need wifi as well, so what do you suggest?

    Any WiFi router will operate with the MB8600 modem. Given the MB8600's speed, you should need at least an AC1900 router, and depending on the rest of your network, you may be able to get a wireless connection even faster than AC1900. The MB8600's Ethernet connection connects to the WiFi network of your choosing. Because you'll require a Gigabit WAN port (10/100/1000 Ethernet port) for the speeds that the MB8600 can give, the router should be up to date. For the time being, Comcast's 1 Gbps service is the fastest cable service available in the United States. The MB8600 contains bonded Ethernet ports, which will allow the MB8600 to offer rates above 1 Gbps when Comcast or other cable Internet service providers begin delivering service speeds above 1 Gbps. We don't know of any consumer-home/small-office routers that support Ethernet port bonding right now, but they're on their way. Ethernet port bonding is possible on Enterprise level routers (routers used in large businesses), but we can't yet suggest that class of equipment to a consumer. They're more intricate and pricey than you need. By the time Comcast is ready to start offering rates exceeding 1Gbps, bonded Ethernet connections for consumers will be available, and the MB8600 will be ready to deliver such speeds. In conclusion: At the very least, use an AC1900 wireless router. Make certain your router has a Gigabit Ethernet WAN port. Description:
