Motorola Gigabit Speed - This thing Rocks!

Motorola Gigabit Speed DOCSIS 3.1 Cable Modem + WIFI 5 Router MG8702
I upgraded my Internet service to 500mb and after a week of reading up on my options I chose the Motorola MG8702 modem - router. I've used Motorola products for over 40 years, from the radios in work trucks to cable modems knowing that they always have a quality product that continues to work for years. This combo has more capability's that am currently able to use but it's there for me when I upgrade my equipment.
With a simple $30 USB/Ethernet adapter I am able to achieve incredible download speeds getting close to the numbers I'm paying for.
Up to 480Mbps so far, about five times what my 100Mbps Intel 1217-LM can. This is on a 10 year old Dell with a 3.1Ghz quad core, 8 threads.
The router is full of software for more provisioning than you could imagine.
I'm very happy with my choice.
