The following steps run through the general steps that anyone needs to take to get connected to the internet via wifi.
Step 1: Locate yourself in a property or public space that has a wireless router. I.e. Somewhere where a wifi signal is being transmitted.
Step 2: Make sure that the device you're going to use is a.) Capable of connecting to the internet and b.) Capable of connecting to wifi.
Step 3: Find out the name of the wifi network that the router in your location is transmitting. That's right, each wifi network has its own unique name. Sometimes this can be a sequence of random numbers and letters if it was set by default on the router — but people often personalize the name of a wifi network to help users identify its owners. E.g. "The Smith Family wifi" or "Fred's Cafe".
Step 4: Once you know the name of the wifi network, use your chosen device to find it. This will vary between devices (depending on whether you're using a Windows or Mac computer, or a mobile device). However, the process for connecting to wifi is broadly similar, following something along the lines of navigate to wifi settings > turn wifi on > click on the name of your wifi network > click "connect".
Step 5: Many wifi networks are made private, with access restricted via a password. If your chosen wifi network is password protected, at this point it will ask you enter that password. Make sure you have the password at hand and enter it.
You should now be connected to wifi!
