Router Problem

[evolvedbullet]

I have a Linkyek router and I am having problems connection to the internet with my laptop that detects Wi-Fi. It wasn't a problem a few hours ago. I do not know what I did in the past to make this problem exist. What I do know is that a direct connection with an ethernet cord works. What could possibly be the problem? I'll post the model of the router if needed.

(Linksys 2.4 Ghz SpeedBooster)

unplug the router, wait 30 seconds, replug in the router. Profit.
