ok, so i got my Dell DW1390 last week, i installed it and didn't work, it was kinda weird because I think i installed it properly. I needed my netbook to go out and do stuff so i've been without internet. I turned it on this morning and Airport was working! weirdest thing ever, i turned it on once again and it was still working. I came back home, turned it back on and AirPort wasn't working anymore!! Is my card defective or did i just install it wrong? idk what to do now lol, no ideas. thanks in advance.
