How to reinstall Dell WLAN wireless card drivers? - wireless card drivers

I made an error that no longer work my Dell Wireless WLAN driver. I think that's why I do not take signals from wireless Internet to very good, while everything around me. Some forums suggested I reinstall the drivers ... Can someone me a step-process step, how? I have tried to update it, but there were no updates. Thank you.
