Can I use Arris SB6121 with self install 150 mbps service?

Hello,

 

I'm doing a self-intall next week and have an SB6121 that I'd like to use. I saw that it is EOL but from what I can tell it can output up to 172mbps and I think I can still use it for self-install?

 

I will be using this with a Nighthawk AC1750 for a small 2 bedroom apartment (900 sq ft.). 

 

Appreciate any feedback on if this is a feasible plan/will work.

 

Cheers,

Joey

No. The 6121 is only supported for up to the 100 Mbps speed tier;

You'll need at least an 8 channel modem like the SB6141 for the 150 tier.
