Arris/Motorola CM8200 DOCSIS 3.1


Recommended Posts

Any word on compatibility with this new modem?  I'm going to get a new modem to see if that helps with my ping problem and the word is that DOCSIS  3.1 is whats needed for Gigabit speeds.  *I dont have gigabit internet.  Just wondering.


Also, which modem would work best out of those on this list?

Be ware that the Arris SB6190 is experiencing some FW issues seen here: 



and https://www.dslreports.com/forum/r31122204-SB6190-Puma6-TCP-UDP-Network-Latency-Issue-Discussion

If you have not seen or heard about it.  :huh:


There are two problems, ICMP and TCP/UDP.


I love my Motorola SB 6180.  :wub: Works great on Cableones 100/3.  :D



I had a SB 6121. Just as good.  ;)


The new Arris SB8200 under discussion here as well:



Got a SB 6183 yesterday. Working great in front of my R1 router: EEE is disabled and no ping issues seen!
