Yes! Keewifi will work great with your current router. When you plug in Keewifi to a power source without the Ethernet cable, it will automatically scan for WiFi signals around your area. A prompt will pop-up asking you to select the existing WiFi network you wish to connect to on your device the first time you authenticate it. Adding Keewifi to your current network will expand your WiFi coverage and boost your WiFi signal in areas where your current router may be unreliable.

Yes, you can absolutely link multiple Keewifi routers together and it's very easy. Once the first Keewifi is set up and connected to an Internet source, additional Keewifi routers only need to be plugged into a power source. Simply use a device that's already connected to the Keewifi network to tap the additional Keewifi routers you wish to link. They will automatically connect with the existing Keewifi network and significantly boost your WiFi coverage.

No, NFC technology is only available on a select number of devices. Keewifi supports any WiFi-enabled device. If your device connects to WiFi, it can be authenticated by Keewifi.

Yes, Keewifi supports WiFi devices with 802.11a/b/g/n/ac so rest assured that legacy devices will be able to connect to Keewifi as well.

Keewifi is currently powered via micro-USB by a 5V (100V-240V) USB adapter that fits into Type A sockets (http://www.worldstandards.eu/electricity/plugs-and-sockets/). It's very likely that many users already own an USB adapter (for their phones or tablets) that supports the same voltage, but fits into the power socket of their specific region(s). It will work with Keewifi.

No, unless you purposely set a time limit on devices or choose to forget devices from your network through our app, you won't need to authenticate your device again.

Any device with WiFi, including desktop computers and smart TVs, can connect to Keewifi. Of course, we are aware how impractical it would be to lug around a stationary device to authenticate it through our proximity technology. Instead, there 2 ways to add stationary devices to your network. The first method is through our app. You can use your admin privileges on your phone or tablet to approve devices within Keewifi's range. We've made it super easy by displaying a list of devices that Keewifi has detected which you will then be able to approve or ignore at your choosing. The second method is the traditional password method. Keewifi has the ability to send out 6 SSIDs (different WiFi networks), so you can set networks with or without passwords and connect devices the old-fashioned way. This function means that you'll still be able to authenticate your stationary devices as you do currently with a WPA/WPA2 password while phones, laptops, tablets, and other portable devices can still use our proximity authentication feature.

The honest answer about the WiFi range of routers is that it's extremely difficult to determine. Nobody lives in a vacuum or a completely empty, open space. The layout of every home, office, or shop is different. No matter how strong or stable a WiFi signal is, it will evidently suffer from interference caused by obstacles (ie. walls, doors, furniture, etc.) that are in its way.

One of the reasons our router features the 802.11ac wireless standard is its improved signal strength and data speeds. It is the best standard current routers offer. We've also optimized our OS to take full advantage of Wireless-AC technology to ensure even better signal reliably. This area is where our enterprise background shines.

Keewifi has 1 Gigabit Ethernet port used to connect the router to your Internet source (ie. a modem or another router). We took many features into consideration when designing Keewifi. Our core goal is creating the world's simplest WiFi router. It was a conscious design decision to include just 1 Gigabit Ethernet port. Firstly, we didn't want to confuse novice users who may plug in the Ethernet cable from their modem into the wrong Ethernet port meant for additional devices. Secondly, it's our belief that all consumer electronics are trending towards a wireless standard as evident by the many laptops on the market which no longer support Ethernet. We believe a WiFi-only router suits the needs of most consumers.

With that being said, we definitely understand that there is still a significant portion of users who may own legacy devices that do not support WiFi. We will be exploring options such as offering a wireless-to-Ethernet bridge/repeater that would allow these devices to be able to connect as well.
