Not connected, no connections are avaliable

So basically today I waked up see my laptop's Internet saying no connections are available. So I went and reset the router still
no network show. Then I go to my phone the internet is working fine on there so is other devices in my house. So I look up fix's for it it said to uninstall the wireless adapter in msconfig I think then click scan for hardware changes but, when I did that it didnt reinstall it then if I restart my laptop it didnt show up either. So I just went on to find a new fix now this one tell me that my firewall is not enable then I goto see if it enable or not and it not but, when I go to use recommended setting it buffers for a few minite then just stops not enabling anything now I need to find out how to fix firewall not enabling this fix say goto services because firewall isn't enable I did that set it to automatic then tries to start it again it loads then pop up this error saying windows could not start the window firewall on local computer...So it comes down to this conclusion I have no permission for anything on my computer I set the UAC to very low try all above steps still same result run everything in adminstrator not working either. So pleaseeeee helpppp!!!

You have to connect with wire and download the wireless driver from your laptop's website (Google its make model and driver download). You may need to enable automatic IP Address and DNS Server from IPv4 properties (Network and Sharing Center - Change adapter settings - Properties - TCP/IPv4 properties - automatic for both).

Hmm, if you can please link me where to download wireless drivers can't seem to find a good download site for it.

My laptop model is Dell inspiron 3135

After the wireless driver is installed my wifi will be back on again right?

Oh and the below attachment are the device manager thing as you can see I deleted the wireless adapter
