No matter how great a keyboard artist you may be, the odds are that you hate joining secure Wi-Fi networks on your Android device. Passwords are a serious (but necessary) pain, but a new, free app called Wifi Joiner lets you easily set up scannable QR codes to let other Wifi Joiner users share your network. Here's how to get started:
Initially, your camera will open up with a message directing you to scan a QR code. In the future, you can just scan to join a network, but we want to set one up, so we'll tap the Menu button and then select "Create."
You now have the option of either selecting a pre-existing network or creating a new one. Select or type the network name, security type, and password, then select "Create QR Code."
Tap the Menu button again and select "Share." This brings up a list of delivery options; just choose one that works best for the people you want to share with and you're set.
It's easy to print and post a code, send it to friends digitally, or just let folks scan the code on your own Android device. It's a much friendlier way of granting access to your network--but more importantly, it makes changing your password regularly much less painful.
