Benefits of DOCSIS 3 modem?

I have been using the same Motorola SB5100 modem for close to 10 years.  It works fine and I rarely lose my connection.  It's not yet on the "end of life" list (whatever that means).  Is there any reason for me to upgrade to a DOCSIS 3 modem before my SB5100 gets added to the EOL list?

You might see a slight improvement in speed if you upgrade, but probably nothing dramatic, perhaps not even noticeable. In your situation I would wait until the modem goes EOL. Comcast describes what "End of Life" means here: http://customer.comcast.com/Pages/FAQViewer.aspx?Guid=9defdd9d-0e45-4216-8b5c-40e9eb19bc3e.

There are benefits to be had by using a D3 capable modem on an upgraded to D3 system such as increased connection reliability due to the multiple bonded channel redundancy and failover capability. There are also increased capacity/reduced congestion benefits which result in increased reliability of receiving one's provisioned speeds especially during times of peak usage/demand. Higher Powerboost assisted speeds have been noted as well. It's a win win for both the provider and the subscriber.

Are there any upgrades or firmware updates that can be done to a DOCSIS 2 modem (ie SB5101) that would help improve performance before going the route of upgrading to a D3 modem?

 

Thanks in advance.

If there were any newer firmware loads available they would be automatically pushed out. But F.Y.I., firmware upgrades to a DOCSIS 2 modem can not physically do what the multiple channel bonding of DOCSIS 3 does. The device's "hardware" as well as the firmware needs to support multiple bonded channels.

So how do I request a D3 modem to replace my SB5100?

Yes. They themselves recommend that a D3 capable modem is used for the "Blast" tier since the speeds have been increased to 25 Mbps down on upgraded to D3 systems.

If you have their "Blast" or any faster tier of service, call in and request a DOCSIS 3 compatible modem.
