Device manager... As in Windows Device manager ?
AT-WCP200G that looks like a card model number rather than a Wireless chipset.. nope not enough info to work with. The same model card can have multiple revisions each of them having a different chipset from a different manufacturer while the model number of the card doesn't change (annoying isn't it ? ) ..
So based on that info We still need the output of the command I requested, so we don't waste time troubleshooting the wrong thing or the wrong driver..
the output from Windows device manager is NOT accurate information.
