Is it a known problem? What AP are you using? This could be a compatibilty issue. Are you using encryption? If so what type? > Here is a screenshot of throughput speed using iperf: http://dl.getdropbox.com/u/158338/benchmark_dlink.png > > Also if I try to transfer data from the card to the router, I get a kernel panic. Can take a picture of the oops message? Please try running in the console to be able to capture these. You can try increasing the size of the screen using something like vga=791 to use the frame buffer. If all else fails you can try the nmi watchdog. Luis
