Describe your thread have a dell inspiron 1545 with a keyboard that doesn't have the WiFi connection key. Can somebody please tell me how to connect it back to the WiFi? I'm getting desperate here.
Need a bit more details about exactly why it won't connect. Did you turn off the WiFi hardware and can't find a way to turn it on now? Do you have the wireless connections showing but it won't connect to your router? Is the wireless card showing up with no errors in Device Manager? You need to post exactly what is going on and what you tried.
