The mandarin guangxi encompasses a whole lot more than just your network. That would be considered a very bastardised translation, losing all the extra meanings such as good luck created by having that network, possibilities to fortune, a kind of karma, and more.
Karma aside, "having connections"/being "well-connected" is pretty much the equivalent in English. It's not bastardised at all; terms don't need to have the exact same cultural implications to be basically equivalent.

In your 20s you might think of your network as people who you went to college with. In your 40s your network takes on a meaning much closer to what you have described. I don’t yet know what happens in your 60s.
