I had some issues connecting the Nighthawk to Xfinity internet. After about 6 hours on the phone, it took a 3-way phone conversation with Netgear Tech (Paul in the Philippines) and an Xfinity tech in India to get it working. It wouldn't have happened without Paul's commitment to making it work! Now the Nighthawk is working great.
Bought it to replace my xfinity box. It's a little prive but does a great job. Setup was easy and quick but it would have been nice to have the manual instruxt you to setup the admin account. It took me an entire day with Xfi itu on the phone to digure that one out.
