Not fixed, the problem just reappeared with 3.8.0-19 this morning: PING asus (10.85.3.65) 56(84) bytes of data. 64 bytes from asus (10.85.3.65): icmp_req=1 ttl=64 time=945 ms 64 bytes from asus (10.85.3.65): icmp_req=2 ttl=64 time=946 ms 64 bytes from asus (10.85.3.65): icmp_req=3 ttl=64 time=900 ms Asus is my router, normal ping times are ~1ms. I'll try to run the apport again with the current kernel, the original run was I think with 3.8.0-17 and might not show the actual problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1168819 Title: Slow wireless with AR9485 ath9k To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1168819/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
