Make sure nobody is using the microwave in your home when you are video conferencing.
Microwaves interfere with WiFi signals because physically they are the same thing. Both produce electromagnetic waves with frequencies around 2.4GHz. The microwave door should theoretically block the majority of the radiation but the fact is there are always leaks and because the amplitude of these waves is much higher than those emitted by your WiFi router, it can lead to a loss of connection.
One option is to make sure your router and workstation are further away from the microwave if it is going to be used while you are working and taking video calls. Another option is to connect to your router using an ethernet port instead, then you won't be using WiFi so it won't be a problem. If you are experiencing drop-outs it may be a result of your neighbour's microwave if they are in close proximity. If you are generally having a bad experience with video calls over Wifi, switch to a hard-wired Ethernet connection and it should lead to a smoother experience.
