Hi Plindsay1973,
One thing to check is the type of network your home router is putting out. The camera is able to detect and connect to 2.4g networks. If the router is only outputting 5g networks the camera would not be able to detect them or connect to them.
One other thing to try would be to connect the camera and computer thorugh the camera's wifi. The steps to do that are on pages 502-507 of the manual. If you need a copy of the manual it is available HERE. Once you are on the web page click on the Manuals button and the one to reference is named EOS M50 Mark II Advanced User Guide (PDF).
To connect your camera and computer through wifi you will also need to have the EOS Utility installed on your computer. If you need that software it is on the same web page I linked above. It will be under the Software & Drivers section and the current version is EOS Utility 3.15.20.
