Why isn't my WiFi extender helping with internet lag?

Episode 1726
Carl fromCarl is a teacher and is struggling with internet lag while doing distance learning, even though he has a UVerse provided wifi extender to help with the problem. Should he buy his own? Leo says that just because you have an extender, that doesn't mean there isn't another issue. It could be your bandwidth is too slow. And WiFi is often not the best way to handle video conferencing. Wiring your connection will always be faster and better. More consistent. You also want to pay attention to your upload speed. If your upload video speed is too slow, it's going to cause lag.
