Greetings.My lap top can't acess to any wireless network but if I plug a cable I can use internet.So,help me how to find wireless drivers.
Thnks

Are you running Windows (which version), or Linux (which distribution+version+kernel)?

Visit Dell's website. Download the latest driver.

I would then suggest that you go into Device Manager, uninstall the wireless device. Let the computer rescan. Once installed, upgrade to the latest driver.
