If you are experiencing technical issues during a call, there are a few steps you can take to improve performance. First, close any unnecessary tabs or programs, as having too many open at once can overload your computer. Next, try to reduce the number of people in the household using the wifi so that only those who are essential remain, which can help improve stability. Finally, consider turning off your camera, as this lowers bandwidth usage and often results in a smoother and more reliable call experience.
