Works great and was delivered quickly!

When purchasing your own modem, keep in mind that you will need to call your carrier and give them the MAC address located on the bottom of the modem. I upgraded from a DOCSIS 3.0 modem to this DOCSIS 3.1 modem to take advantage of an upgrade from 300 Mbps to 600 Mbps. The very first speed test that I ran showed an upgrade from the 340 Mbps that I was getting to 687 Mbps immediately. Do I need that kind of speed… no. Do I want it… yes. I ordered it for delivery via the Walmart website and got it as quickly as I would have if ordered on Amazon. It was less expensive at Walmart by about $40 at the time of purchase.

Good Brand

To be honest, I returned this modem because it didn't solve the problem I was having with my internet connection dropping constantly. I have since discovered that the problem was my router, not my modem, which is why my review is positive. Though this one wasn't used by me, the one it was meant to replace was the exact same brand, which I love and have truly had no problems with, even though I thought I did at the time.
