We all know the scenario: a friend or family member is at your place and needs to connect to the Wi-Fi. At that point, you have a few choices (none of which are ideal): hand them a piece of paper with the network key, tell it to them aloud, or enter it for them.
Wouldn't it be so much easier to let them tap an NFC tag (granted they actually have an NFC-capable phone) or scan a QR code? Dang right it would - and now the process of making that happen in stupid-easy thanks to a new apps called InstaWifi.
InstaWifi lets you easily share your network information with a simple tap of an NFC tag or scan of a QR code. And it does so with very little hassle to you: fire the app up, enter your network SSID and network key, and either write it to an NFC tag or print a QR code. Done.
It's even easier if you have a rooted handset, too; InstaWiFi will automatically dig into your network settings and pull out all of the information that it needs. Super simple.
It's worth noting that I had some trouble getting the application to work on both my Galaxy Nexus and Nexus 7 when I tried to use the NFC tag (it kept failing authentication while trying to connect to the network). However, Artem got it to work without issue on both his Nexus 7 and EVO LTE. We've reached out to the developer to see what the issue may be (we suspect that it may have something to do with special characters in the network key) and will update when hear something back.
In the meantime, this app is definitely worth checking out. Even if you run into issues like I did, I wouldn't stress too much; up to the point we've had good communication with the developer, so rest assured that a fix will likely be hitting the Store soon.
