There is nothing more frustrating than having your connection "freeze" right in the middle of a story. There are a few simple things that you can do.
1) Choose the best connection:
The best connection is a wired connection. If you can, plug your computer into your modem with an ethernet cable.
Wireless is the next best option.
The closer you are to your modem, the better your connection will be.
Turn off anything in your home that might compete for your wireless network. Phones, baby monitors and other computers may interfere. YouTube, Netflix or Facebook should be turned off, along with SkyDrive, Dropbox and other programs that synch your files.
Telephone data will give the weakest connection....and may cost you a fortune!
2) Mute your microphone when you're not speaking.
Programs like Zoom use internet to keep your audiostream open, even if you aren't speaking.
3) Stop your webcam
It isn't ideal, but sometimes, the only way to stay connected is to turn off your video.
4) Disable HD webcam video
High Definition video takes up a lot of bandwidth. You can switch to a lower quality video by following the instructions here: http://web4.bilkent.edu.tr/zoom/frequently-asked-questions/how-do-i-disable-hd-video-in-zoom
5) Close other programs
Close any programs that you don't need for your teleconference.
