There are faster and more feature rich models out there (some premodded, some not), but for me and my situation, this one works wonderful. In my case, I could use this one to substitute for my subbed modem, and, using the stock configuration file, have everything humming along nicely.Īs far as a DOCSIS 3.0 Modem goes, it works. In my case, I've used alot of SB51XX Premod modems before, so I knew what will work, and what won't for my cable system. You have to determine if this modem is for you, and how to get it to work. There are quite a few How-To's out on the Web.Ī negative point: It can take awhile for the modem to reboot, and then foe your router to actually get it's DHCP address/etc from the modem, and actually connect to the internet. Make sure the "Start Mode" is set to "Online", "Tuner CFG" to MT2170, and the "PGA Type" to MT1570. Nice and fast, most options are fairly easy to understand, and it works.

After reading and reading, and reading some ore, I hooked it up, changed a few parameters to let it connect, and success! With that out of the way: It works great for what I wanted.
