Hello Everybody I´m usind a D-link USB Wlan Adapter DWA 160A (ar9170usb) under Debian (kernel 2.6.31) First when I connect this device, everything is fine. I have to do some measurements concerning Mipv6 (I´m only using Ipv6 here) after a while using this W-lan Adapter (30 to 60mn) the system is not be able to receive any packets. The only solution is to plug the USB interface out and to connect it again. ifconfig down and up has no effect and sometimes rebooting either don´t correct this. Any idea what the problem could be? iwconfig wlan0 ==> wlan1 IEEE 802.11abgn ESSID:"homenet" Mode:Managed Frequency:2.447 GHz Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Ifconfig wlan0 ==> wlan1 Link encap:Ethernet HWaddr 00:22:b0:71:a0:f3 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:1604 errors:0 dropped:0 overruns:0 frame:0 TX packets:1886 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:212557 (207.5 KiB) TX bytes:296773 (289.8 KiB) My message logs: [ 1017.309330] device wlan1 entered promiscuous mode [ 1057.151376] device wlan1 left promiscuous mode [ 1069.824693] device wlan1 entered promiscuous mode [ 1109.161762] device wlan1 left promiscuous mode [ 1123.640991] device wlan1 entered promiscuous mode [ 1130.289499] device wlan1 left promiscuous mode [ 1270.206139] usb 5-2: kill pending tx urbs.
