I using the DNMA-H5 from unex and compat 2013-04-16. If the equipment with this card is placed in 30°C environment, with iperf I can send 150 Mbit/s. If the equipment with this card is placed in 0°C environment my throughput is not stable and is around 40Mbit/s. In this condition, I receive some CST interrupt burst. If I correctly understand the ATH9K driver code, when this interruption occur the driver only increase the interrupt counter. Have you any information on this interrupt ? I googled but I don't found any information. Do you know if the driver need a specific action to handle it ? If yes, could you give me some pointer to do that ? How I can increase the timeout Value ? If I tried with other Wireless card (DNMA-83 from unex for example) I have not this problem. Any help will be appreciated. Best regards.
