The white signal bars to the right is how you would connect to wireless.
Is your moms computer an HP? If so, I believe it's HPs wireless assistance icon.
Yeah. I'm good with computers, just for the life of me I couldn't realize what the tower was. But every minutes the computer will freeze up, the mouse and the trackpad. Then the wifi signal will appear. I'm thinking the wifi card could be going bad?
Looks like some kind of wireless assistant, try uninstalling it.
