Please explain to me laptop internet connection (routers, wi-fi) completely lost?!?

Here's how it works....

You have the INTERNET connection provided by Suddenlink ==>
Your MODEM connects to the internet==>
Your ROUTER takes the internet signal from the modem and ROUTES it to all computers connected to the router ==>
Your router usually has ethernet ports (wired network) and a WIRELESS network access point ==>
The WIRELESS portion of the router broadcasts your WIFI internet signal locally usually with a range of 100-300 ft. ==>
Your laptop has a WIRELESS card built into that will receive the signal and connect your laptop to the INTERNET (key music... the circle of life)
