How can I raise the connection quality of screenshare on a public (co-working space) WiFi network?

The answer is more than likely related to the co-working space wifi. There's a few steps I'd take in order. 1. Perform a test call off site on wifi. 2. Perform a test call off site on a wired connection. Did either of these seem to resolve quality issues? If so: 3. See if you can ask the co-working space for a wired connection. Neither issue worked, or the space declined to cater to your request? 4. Seek a new workspace if possible. Hope this helps somewhat. Using this service over wifi at my office worked fine, so that is why my first assumption is to look at the internet connection on the client end.
