Motorola SB6120 SURFboard for Performance Select 100mbps plan

[WRayX]

I got the modem about 10 years ago and it still works. The spec sheet says it's good for 160mbps. Since my plan is upgraded from 15mbps to 100mbps, does that mean I don't need to upgrade my modem?

Do you get the 100 Mbps speed ? That modem is a Dinosaur !

I know, but it just doesn't die.

I got 15mbp plan before but when I do speed test with google, i got 15-19mbps download.

After upgrading to 100mbps, my new google speed test is about 4 to 5mbps download.

I need a new modem I guess.

Actually, i found a wrong router setting that's limiting the speed. After i fix that, my SB6120 gets 110mbps on my 100mbps plan, so I'm going to cancel my NETGEAR Nighthawk CM1100 DOCSIS 3.1 Cable Modem since my dino works.
