I found a workarround: "sudo iwconfig wlan0 power off" solved the "No Probe response" problem... Sometimes the ping is over 200ms,.. but the network is very stable now..
ping statistic to my router: "60 packets transmitted, 60 received, 0% packet loss, time 59086ms" So the problem is still related to the powermanagment of the driver!? -- ath9k disassociates/reassociates a lot https://bugs.launchpad.net/bugs/414560 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
