How can I improve my Macbook wi-fi?

[chrisjchrisj]

I have a 2009 Macbook. Is their any device or upgrade I can add to it to improve Facetime video call sessions? I'm not looking for inexpensive solutions, I need it improved for work. Something that might help with latency, speed or quality for when I'm traveling. Thanks

You need a better network for those things to improve.

Doesn't it also apply to the other party that he is communicating with?
