Hi, I'm having trouble on having a stable connection with carl9170 driver and d-link DWA-160 (A2). When idle or almost idle (ssh etc traffic), the driver works without issues. However, even medium intensity traffic (1MB/s) all traffic will soon stop, and the driver will start reconnecting. This is with a 802.11g wpa-psk network that works fine with iwlagn equipped laptop and mobile phones.. Usally the only sign in the logs is: Jul 11 10:47:33 aimless kernel: [ 6130.120936] wlan0: deauthenticating from 00:1d:19:ad:d7:65 by local choice (reason=14) With then lots of authentication attempts and CRDA noise until succesfully connecting in a minute. The attached log includes a usb reset and firmware load which doesn't happen always.. Riku
