@Glazebrook65 video calls need a stable data feed of at least 10Mb/s up and down. You can run a speedtest to see what speeds your device is getting. If that looks sufficent but calls still drop tgen the issue is likely to be inteference which canncome from your neighbour's networks or even from your own equipment keep any wireless devicesxwell away from the hub and you device.
Ideally use an ethernet cable as that is by far the best connection for working from home. Otherwise move closer to the hub or consider upgrading the WiFi in your home.
