4. Ports

Older versions of MB8600’s modem used to come with four ethernet ports and a single WAN port. The coaxial cable is plugged inside this WAN Port whereas the ethernet port is used for connecting the device with the modem. There are four ethernet ports but you can connect only a single device at a time. This device also works in the same way as that DOCSIS 3.0 modem works.

What is it’s Drawbacks?

1. Just one Ethernet port

Older models of Motorola MB8600 had 4 ethernet ports but users are allowed to use only one port. this issue was later resolved by Motorola. The latest models have only one 10/100/1000 Gigabit Ethernet LAN port. Now, users are left with only one port and if unfortunately, this port stops working then the modem remains of no use.

2. 6 Gbps Speed Limit

The MB8600 boasts of giving 6 Gbps Speed Limit. The DOCSIS 3.1 can reach up to 6Gbps speed, however, with present ISP, their service and load capacity is not capable or updated enough to provide this much speed to users. The DOCSIS 3.0 is only capable of managing speed up to 1 Gbps. As a result, the theoretical results and real-time results have a wide difference. The user may pay for better services but unless the ISP s updates their service, investing money in such service does not seem feasible.

Nevertheless, if you are a technology buff and have an interest in buying and using new technologies, then this modem will surely attract you.
