Also, include the make/model of your computer and the wireless chipset.
Running the command lspci in a terminal should provide the wireless chipset. The odds are that the issue with wireless connectivity traces back to getting the correct drivers for the wireless chipset.
Be sure to surround any terminal output with "Code" tags which become available when you click the "Go Advanced" button at the bottom of the "compose post" window.
Keep in mind that the more information you provide the easier it is for others to help you.
