I had a TL-WN725N that was working fine on a legacy Windows computer.  Had the hard drive replaced, and now cannot get it to work.  There is no power light - it does have it on other computers, and the  USB ports in the new one read  other flash drives fine.  Device Manager recognizes it not as TP.Link but "802.11 in NIC", and there's the yellow exclamation by it, and while I have the driver install disc if I try to " update driver" in Device Manager using it, it says there are no usable files on it.  I'm at a loss, any help pointing me in the right direction would be appreciated.
