i have a dell vostro 1088 notebook with windows 7 (32 bit) on it. the problem is that until yesterday my wireless was working fine but suddenly today it is not detecting any wifi network and also the device manager does not show any wifi card or adapter.on installing the driver it says "qmi module not exist". Huh?

i tried to setup a new network,; it gives me the option of broadband or dial up only.. no wireless. Sad i even formatted my laptop with a fresh copy of windows 7, 32 bit, still of no use....

also my display has a problem...  sometimes when i plug in the power cord the screen goes white and then i hav to close the lid, wait and then open again to get back my screen [my batteries have gone bad so i have to run it on power only]...

can anyone please help asap??

PS.: its just 1yr 7mnths old
