I just bought a brand new rig with an Asrock fm2a75m-dgs motherboard so i installed Windows 7 x64 and tried to get wifi connection with my old TL-WN727N, but when i connect it the USB slots (both front or back) there is a error sound.
I cant install the drivers with the setup.exe because it says "connect the device"...but it cant detect it!
I tried looking on device list but all i see is "802.11 n wlan" with an exclamation sign. I click on fix problem and try to show the place to the drivers...but no way!
I thought it's my TL-WN727N... but my flat mate has a TL-WN722N and i tried to connect with that one but it has the same problem!
can anybody help me please?
This stuff is realy getting on my nerves
