the nic card is a simple tf3200 model from tplink.the back ground story is too long..I have been having problems with my btcl connection for 1 week now...then last night I was again trying to connect to see if I can reconnect to my btcl or not...other times it produces a hang..this time is showed nothing...then my network sharing center hanged up(which never happened before)...after that my nic started showing cable unplugged(which is not)..then no matter what I try..uninstall reintall my nic driver...unplug or replug it..restart pc.....but no results...couldn't try a different slot cause I have none but 1..can't think of some thing else....these whole net business is driving me la..
