One other thing is that I disabled every feature in my DIR-615 access point. So no 802.11d, no protection no WMM, no nothing and switched back to 802.11g instead of 802.11n. And after starting a download for 600 MB image, it stopped half-way through and my connection broke down. The AP kept working for any other device that was connected to it. So this issue is way strange. Regards Marcel
