Copy the journal to a USB drive: without logs, this isn't going to go far. Also, provide more detail about your cards, drivers, network manager, etc...

I had such an adapter for a while but then replaced it because of this issue. The driver isn't stable yet (the topline of your dmesg tells you this, its from the staging tree) I don't think there's any magic switch you can flip other than hope that this is going to be fixed somewhere down the line (the driver has been in staging for a couple years already though, so I wouldn't hope for much in the forseeable future)
