To begin: I have not been a NetGear fan for a long time [I am an IT Tech for 34+ years. Yes; I started with DOS 2.0] I cut the cable TV 'cord' and upped my net speed from 25 Mbps to 300 Mbps ~1.5 months ago. My old [Arris] Motorola SURFboard SB6141 DOCSIS 3.0 was stuck at 25 Mbps [w/ a GB network throughout the house]. The cable provider tech support tried many times to push the latest firmware to no avail. I went through every connection point from the street through the house. I had the cable from the street box replaced. I was then ready to replace my ASUS RT-AC68R router. That is, until a net search found a long running conflict with Motorola's SB6141 firmware & cable providers system/tech support. I bought this modem as a last resort to obtain the 300 Mbps speed I was paying for... Magnificent!! This modem is easy to configure - Rapid, flawless registration & update to firmware by the cable provider. I never had to call tech support. Every step was on-line. There was an immediate improvement in download/upload speeds. An initial speed test with a single isolated PC received 50% above the 300 Mbps download speed. Upload went from 5.91 Mbps on the SB6141 to 30+ Mbps --- Living the life streaming on everything. Good Job, NetGear!
