I have had absolutely no problems with my new router. Always connected, always putting out a strong signal. I would highly suggest the Nighthawk AC 2300 Smart Wi-Fi Router to anyone looking to upgrade.
The reliability of my wireless signal with this router blows the doors off the modem/router combo that it replaced. Streaming HD content at multiple devices in my house at the same time has been working great.
So far, and it has only been a week or so, the unit has performed to expectations. The range has been extended over my previous router so that all areas of my 1800 square foot house are covered.
