In a way that shows a lack of patience or eagerness for something to happen.

Impatiently → It is formed from "im-" (meaning not) and "patient" (from Latin "patiens", meaning suffering or enduring) and the suffix "-ly" (meaning in a manner). The word "impatiently" describes the manner of not being able to endure or wait calmly.
Think of 'not enduring' ('im-') something patiently — that's why impatiently means to act in a way that shows you cannot wait.
