I just did a quick test. I think that you may need the DWC_AUTHDATA:
1) I ran Brawl and went online. No issue
2) I removed the DWC file from the Dolphin Emulator folder. No online connection.
3) Put it back in (didn't shutdown Brawl), and it connected right away.
My file was created back in October, and not by me (by Dolphin I guess), so I didn't even know it was there.
