This modem replaces my previous Motorola Surfboard 6121, which worked great until I saw the results a friend posted with his new 7420.

I am an avid Motorola fan when it comes to Cable Modems

When my cable company asked to get a new router because my old Motorola was no longer supported I looked at another Motorola.

My provider recommends the Motorola SB6183 or Netgear C6300 for my 400/20 connection

However, the Motorola MB8600 works on iPV4 and iPV6 and Docsis3.0 and Docsis 3.1 . . .

However, for replacing a rental modem, I recommend this Motorola.

Motorola MB7420 686 686 Mbps DOCSIS 3.0 16x4 Cable Modem works well with Comcast Xfinity upgraded network.

Also talked to Motorola support and no joy

And most importantly, the Motorola improved both my Download and Upload signal strengths by about

My Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem (purchased in 2011) only supports 4 downstream channels, and lately my internet connection has been spotty.

Overall, enjoying these new Motorola!

Motorola is not the cheapest, but it never has problems

For the easy with that I applaud Motorola

I don't get any faster up or downloads, but that's not Motorola's fault

I bought this modem to replace a failing Motorola modem that I had for several years.

Got this Motorola and all devices work perfectly at high speed all at once

Much the same quality as any good motorola modem out there, considerable future proofing though for most cable plans out there, but nice to have

If you have a internet plan that is 150Mbps Down, or less, then this Motorola MB7420 should be perfectly adequate for you.

Loving my Motorola MB7420 Cable Modem

This Motorola MB 7420 modem works great

One pay's extra for Motorola to have peace of mind.

Motorola has an 800 number if you need help.

Between the SB6183 and MB7420, Motorola won me over with the Full-Band Tuner and integrated surge protection

300M down and 30M up... awesome.. all for the same price with a renewal

Installed in minutes (except for hold time with Comcast) - RECOMMEND A+++++

As far as I can determine, it does the job as well as or better than the rented one it has replaced, and will save me nearly $150.00 per year
