Internet connection problems...?

[Jade]

I have a laptop that used to get internet from using netgear. I used to use internet connections from someone around me. But not none of them work. It won't say "connected to router" and then "connected to internet" anymore like it did. Everything will just be red. I am getting very irritated by it. No matter where I am in my house nothing works. It has not worked for almost a year. If you got any suggestions on what may be the problem, I would greatly appreciate it.
