Netgear Zing review:

Excellent mobile router if you can get Sprint 4G

Mobile routers with touch screens aren't new, but the Zing brings this to a new level. The device's screen doesn't just show the router's status and settings, but also provides a place to customize all of its settings and features. On the home screen, you can quickly view the number of connected Wi-Fi clients, the amount of data that's been used, the battery life, and so on. You can dig deeper via five buttons: Devices, Wi-Fi, Settings, Billing Cycle, and Session.

Each of these buttons leads to more functions or settings that you can customize. The Devices button, for example, shows you the connected devices' IP address and MAC address, and you can also block or unblock them if need be.

Obviously, you can only use the Zing's touch screen if you have it in your hand; when it's out of reach, you can also customize it via the Web interface. This is especially convenient for those using a laptop or desktop computer. You can access the interface by pointing a browser from a connected computer to the router's default IP address, which is (the default password is "password"). Here you'll find the items and settings are organized similarly to on the touch screen.

The Zing supports the basic settings of a regular router, such as port forwarding, port filtering, UPnP, and so on. There's one unique feature: you can create a secondary Guest Wi-Fi network in addition to the main Wi-Fi network. Devices connected to the Guest network can connect to the Internet but can't talk to one another or to those connected to the main Wi-Fi network. Since the router supports a maximum of 10 concurrent Wi-Fi clients, you can also choose the number of clients allocated to either network. For example, you could make it so 7 clients can connect to the main network and 3 can connect to the guest network.

Unlike other mobile routers, the Zing has another way for you to manage it: via mobile app. The app is called Netgear AirCard, and it's available for both iOS and Android devices. Using this app, you can manage the router similarly to using the Web interface, but a lot more conveniently if you're on a mobile device.

The Netgear Zing wasn't the fastest mobile router I've seen, but most likely this is because at the time of the review, Sprint hasn't officially launched its 4G LTE service in the San Francisco Bay Area. Yet, the Zing -- like the MiFi 500 LTE -- was able to pick up full 4G LTE signal in many parts of the city. And in my testing, it was much faster than the MiFi 500 LTE and much more reliable. Speeds of both download and upload were generally stable and averages around 6.1Mbps and 3.5Mbps for download and upload, respectively. Compared with other mobile routers from other carriers that I've reviewed, these were still below average, however.

Note that this is what I experienced in the Bay Area. As with all mobile routers, cellular Internet speed varies a great deal depending on where you are and sometimes even on the time of the day. So you might get totally different numbers where you are. However, after a few days of testing, I believe the Zing delivers the best of what Sprint has to offer.

As a mobile Wi-Fi router, the Zing was excellent, offering very good range and a stable Wi-Fi signal. Though Netgear only claimed 10 hours for it, I was able to get more than a day out of the battery with regular usage by two devices at a time. Note that battery life also varies a great deal depending on usage and settings. For example, if you let the device go to sleep when idle, refrain from playing with its touch screen, and don't use the GPS function, then its battery will last much longer than otherwise.

The Zing has a lot going for it, including the convenient touch screen, great battery life, and faster 4G speeds than the Sprint MiFi 500 LTE. However, currently, it's a little hard to enjoy the device since Sprint's 4G LTE coverage is still sparse and even when there's coverage, the speeds aren't the best I've seen. Hopefully this will improve over time, and only then will the Zing rank among the best mobile hot-spot routers on the market. For now, it's only the best among what Sprint has to offer.
