My wireless stopped working; had a local tech check it out, my internal card worked fine in other systems and the wireless network at home worked on other laptops and peripherals.  The tech thought perhaps an internal antenna had gone bad/become disconnected, so I went to an external card.  No problemo, worked fine.  One night this week, it just stopped working.  No one seems to know why.  I can't ever find the right help on the Dell site nor speak to a live support person, so via email (from India, I assume based on time and names) Dell support tells me I need to pack it up and send it to them for a week to fix.  I really do not like Dell at this point.  This may be my last purchase from them.  And I've always had a Dell.
