FAQS :
This modem's four Ethernet ports produce the same amount of bandwidth, or do just select ports run at their maximum capacity?
The Motorola MB8600 cable modem I purchased in May of 2022 has only one ethernet port, not four.
I'm dissatisfied since having an additional port is quite useful for troubleshooting with a laptop that is directly connected, avoiding the separate router between the MB8600 and the rest of the network.
Confirming that despite extra LAN ports, only one device may be connected to the modem. You cannot connect your computer and a router at the same time.
Answer:
The MB8600 supports a single device.
You may connect either your computer or a router to the MB8600.
If you are paying for and receiving more than one IP address from your Internet service provider, you can connect up to four devices directly to the MB8600.
I require wifi as well; what do you recommend?
The MB8600 modem is compatible with any WiFi router.
Given the speed of the MB8600, you should utilize at least an AC1900 router. Depending on the other devices in your network, you may be able to benefit from an even higher wireless connection.
ARRIS/Motorola supports firmware updates for the 6183 via consumer PC downloads? If not, then why?
If there are updates, you will be able to download them, just as you would with any other piece of computer hardware.
The cable providers have NO influence over the content you download or the modem you employ.
It may not function if it does not use the proper protocols, but they will not exclude those that do function.
What distinguishes this modem, the SB6183, from its predecessor, the SB80?
The SB6180 provides channel bonding of up to 8 downstream channels and 4 upstream channels, allowing an operator to provide advanced multimedia services with downstream data speeds exceeding 300 Mbps in DOCSIS mode and 400 Mbps in EuroDOCSIS mode, and upstream data rates exceeding 120 Mbps.
Do the majority of customers require such a quick cable modem? Is Comcast performance available?
Answer: DOCSIS 3.1 is here, true.
And the initial group of cable modems utilizing the standard will give enhancements.
As with many technology, they do not immediately saturate the market.
In the majority of instances, it might take three to five years for a technology to become commercially available and mature.
