Missing wifi network menu icon

[Ron Fiedler]

I am not a computer guru by any means but I usually don't dismiss items by error. I installed linux lite about a year ago and mostly use it with my home wifi network but sometimes I take it away from the house and want to log on to other wifi systems (such as a hotel) and when I attempted to do so last week I found  the wifi menu listing that used to be in the lower right corner along with the speaker volume icons to be missing.
I can do without the volume control but would like to find the wifi icon and put it back where it belongs. Does anyone have an answer for me? I am not literate enough to write code.
Thanks
Ron
