Please purchase a phone stand to hold your smartphone over your desk. If you don't have a smartphone, use a basic document visualization USB camera.
For reliable connection quality, use an Ethernet cable (which might also require an Ethernet adapter) to connect your computer and main router (the main router is the router that receives the internet signal where it first enters the home). If this is impossible, enable a 5-GHz or 6-GHz band on your main router, connect your computer to the corresponding SSID, and put your computer as close as possible to the main router.
A pair of wired headphones is recommended for minimizing feedback/echo.
