Even though not many of our visitors needs a guest WiFi access I’ve still always wanted to have a guest WiFi network for random visitors. The problem with secured guest WiFi is passing strong complicated password vocally or in paper. I wanted to do something different and pass it to guests with QR code instead.<\/p>\n\n\n\n

But…putting some plain QR paper on the wall is quite boring, so decided to do it a bit different and implement it inside my daughters art.<\/p>\n\n\n\n

Setting up guest network with UDM Pro<\/h2>\n\n\n\n

I’m using UDM (Unifi Dream Machine) Pro as my main router and it does support guest WiFi out of the box like many other brands do as well. <\/p>\n\n\n\n

First thing I did I created a separate isolated network (VLAN) for the guests to use. I don’t want anyone from guest WiFi to access my private devices or home automations of course.<\/p>\n\n\n\n

With the isolated network in place a guest Wifi network has to be done and map it to that specific VLAN. Unifi supports it out of the box, so not much of configuration has to be done.<\/p>\n\n\n\n

After the isolated network has been created guest WiFi was made with SSID + password on it. This guest WiFi was mapped to the previously created network only. <\/p>\n\n\n\n

Now I’m having a fully working guest WiFi system in the house!<\/p>\n\n\n\n

Embedding WiFi within the QR<\/h2>\n\n\n\n

QR codes are like barcodes, but can fit more data in it since they are two dimensional.<\/p>\n\n\n\n

Also most smart phones (Android 10+ and iOS 11+) can read a QR code with WiFi settings in it. That simplifies things since we don’t have to ask visitors to install separate app to read QR codes.<\/p>\n\n\n\n

The internet is full of QR code generator apps that can be stylished event with different colors and logos on it. For my usage I did make just a simple plain black and white QR code using WiFi QR Code Generator web app<\/a>. However, I recommend not<\/strong> to use any <\/strong>random QR code generator since of course they can steal the data you are inputting. The one I linked above seemed to be secure and is not trying to steal any data.<\/p>\n\n\n\n

Of course SSID + password can be retrieved from the QR code itself, so nothing too sensitive should be put inside the code.<\/p>\n\n\n\n

Making the WiFi stylish<\/h2>\n\n\n\n

And then the fun part! My 11 year old daughter loves to draw and is a good artist already. I asked her to draw me a picture that includes the generated QR code and gave her a free hand to draw anything she likes. <\/p>\n\n\n\n

She decided to draw it with her graphics tablet digitally so when finished, I printed it on proper size and framed the picture. Now the my guests can just scan the code from the piece of art and connect to fast 1G\/1G guest network \ud83d\ude42<\/p>\n\n\n\n

Ps. that QR code in the picture uploaded to the internet won’t let you in my WiFi \ud83d\ude09<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"
