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.

Arris SURFboard model SB8200 Quality

This Arris SURFboard SB8200 Cable Modem is so-so much better than the old Arris lower model number that lasted only 4 years! I'm not sure how long Modem's are supposed to last, but this new model, costing $170, HOPEFULLY will last LONGER than 4 years because of the price! This New Model is also much faster connecting than the old model.

Good to have if you need to update your Internet

I updated the previous modem I had to this one. The connections are similar so it was simple to install. Since the amount of devices we have are growing it made sense to get a stronger modem to support them all. So far it's been reliable and fast. Note* this modem does not have built-in Wi-Fi
