Ah, good to see another Dell Inspiron 1525 user about. Gotta love that broadcom driver eh? Well, with a bit of googlin' I found this wonderful tutorial. This got me up and going in a matter of minutes. This article also teaches you a thing or two about how linux works in general.
Enjoy, let me know if you need any further help.Code:hxxp://jomcode.com/fadhil/?p=59
