Make your Network Strong
Many people have much worse internet connections than they expect. Specifically, they suffer from packet loss.
In layman’s terms, packet loss is when your computer wants to send some data to another computer, but along the way, some of that data gets lost.
Packet loss can happen for many reasons, but the primary way is usually lousy wifi connections. Wifi is unlike other mechanisms of data transfer, and it suffers from interference from external sources. A neighbour using a cheap microwave may cause your wifi to start dropping packets.
Packet loss isn’t a problem with regular internet use, and if a data gets lost, then the network detects that and the data is resent. However, for real-time data transmission, of which voice conferencing is an example, that data can never be resent. By the time the data is marked as lost, it’s already out-of-date, resending the data doesn’t make sense.
To others, for various reasons to do with voice audio compression, this sounds like you getting a robotic voice and eventually, if the packet loss is substantial enough, your voice cutting out entirely.
The only way to fix this is to improve your network connection, move closer to your wifi router, get wifi router with a stronger signal, remove sources of interference from your work environment. If all else fails, use an ethernet cable to connect your computer to the router directly.
