So wired networking worked fine, but Linux fails to see your wireless card, just like it fails to see mine and many many other user's cards who have posted that problem. Why in the world you you think you need a "wireless bridge"? Why would you think that adding another node somewhere would help if the problem is that Linux doesn't even recognize the card?

You haven't given people any information about your card, so others can't tell you if Linux is know to work with that card or known to have problems with it. But I would suggest you read other posts in this forum that have gone over the same problem over and over again.
