Never any issues. Can handle all of my equipment, including laptop, desktop, tablets, phones, TVs, out and indoor cameras. Very nice looking clean lines for display. Very easy to install. Price a little high, but worth it!
I decided to try the NETGEAR Nighthawk so I wouldn't have to keep paying a rental fee with Xfinity. I have noticed no decrease in speed and the modem stays online with no issues.
I bought this because my old modem would go offline and the WiFi wouldn't reach my garage. Now my speeds are great, got great coverage and I haven't had to reset my modem in 3 months.
