Hi, The wireless connection keeps failing shortly after being established. Up to now, I've tracked it down to a DMA transmission sequence error in ring 3. Beyond that, I cannot say... Happy to provide further information and to test any potential fixes.
Have you applied the patch that increases the number of RX ring slots? It is commit ccae0e50c16a7f and was committed on Feb 17, 2013. That fixed a lot of problems on the BCM4312. It seems that the firmware fails to check for overflow of the RX ring and blindly corrupts things.
