Unlike public WiFi access points in airports and coffee shops, work and home, private WiFi networks are protected by a passcode. To connect to these networks, you’ll have to provide the required passcode, and only then, you can gain access and browse to your heart’s content.
The same is applicable for WiFi hotspots created through the use of an Android device. As good as this password protection is, it can quickly get more tedious if the code is alphanumeric, long and complex. A QR code may come in handy in such a situation.
You will need the name of your network and a pre-set passcode for the creation of a QR code.
In case you didn’t set up your network on your own, you may be able to find these details written on your router/modem or in the manual provided by your internet service provider. Or you can simply ask the company or the person responsible for setting up your WiFi.
The QR code generator from ZXing project can be a popular choice. It’s free, and even a layman can use it at a moment’s notice.
There are also plenty of QR code generator apps available on iOS and Android platforms capable of doing the trick nicely.
Download the QR code, print it like you would any other document, and put it up for display. Make sure you put it somewhere visible for trusted visitors; not for the ones you wouldn’t want accessing your wireless network.
This one’s one of the most popular apps you can use to generate a code at a moment’s notice.
