Dell Inspiron 3541, no network connection

My Inspiron 3541 is having issues. I was using it fine on wireless internet, then the next time I went to use it, its telling me there is no network connection. My router is working fine, Im on a different laptop right now at my house.

i tried going into the network and sharing center, looked everywhere in there, and there was nothing at all about my wireless network in there. i went into my PC network setting, and the only things that show up are my VPN and Ethernet status. nothing about wireless. I tried troubleshooting the problem, but all it did was tell me to plug in an ethernet cable.

Its like all wireless capabilities just dissipated from my computer. I even tried pressing Fn F2, but that didnt help.

Any help here would be greatly appreciated.
