This will only work with a wired network connection and so you will need to connect your computer directly to your hub - It will NOT work over WIFI
Most PC's have a network socket built in, as do iMac/MacPro and Mac Mini
Plug your network cable directly into the wireless hub
Once you have installed the Jamkazam software there are many videos on how to set it up.
It will work best with an external sound device like this .... USB sound card
Search for "USB sound card" or "external sound card" - this is not essential but it will improve the connection quality and reduce the delay (latency) as it is not using the internal sound card. With these you can plug your normal gigging microphone directly into them so will save on having to buy a USB mic.
If you do not have an external sound card you can use one of the many USB mics that are out there.
Failing all that you can use the built in mic (laptop) but it will sound like you are singing into your telephone to everyone else!
Follow the onscreen instructions that will guide you through setting up your gear, it is quite well explained so no need for me to go through it all here.
Once you have set it up let me (John) know and we can do a test session to make sure all is good rather than delay everyone else.
