I'm picking on the blue lights because they're really my only complaint: excessively bright blue indicators make it hard to see the pale white net indicator. I plan to put some kind of box over the whole thing. But on the positive side, this modem is very reliable, has a nice diagnostic page accessible from the network, and is more than fast enough for my Comcast Blast! service. Even when coupled with my modest Linksys EA3500 router, I consistently hit 89mbps downloads and 12mbps up, which is exactly what I was getting with the much more expensive box that Comcast was leasing me.

Great modem. Very simple to setup and get online. It pulls up to 300mbs I think, but I only pay for 75mbs which is fast enough for me. Easy on the wallet especially if you catch it on sale. Only con is the blue leds are very bright at night unles you throw some electrical tape over the face. Up to you... definitely worth the buy!

I bought a similar unit from Amazon but the product they have didn't have what was claimed to have and even more costly. The Motorola - SURFboard DOCSIS 3.0 High-Speed Cable Modem have performed what it claimed to do to my satisfaction.up to 343 Mbps download and 131 Mbps upload which is more than I need. I would definitely recommend this product to my friends.

This Arris modem has been nothing short of excellence since the day I plugged it in. I have had zero issues and my internet speed is A+. I recommend to anyone trying to save a few bucks on their cable bill.

On black Friday with everyone on a phone or IPad the speed was still good.
