Few more notes: Watching from the commandline this time; ifconfig showed the network interface up throughout, no errors reported.
Ping times were pretty bad - 90-120ms to another machine on the local network. Once fixed this was more like 1-5ms. Occasionally much longer pauses. Then: 64 bytes from mab.local (192.168.0.163): icmp_seq=171 ttl=64 time=89.3 ms ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ^C --- mab.local ping statistics --- 199 packets transmitted, 158 received, 20% packet loss, time 230681ms rtt min/avg/max/mdev = 1.150/75.710/1018.121/97.880 ms, pipe 2 Restarting the ping seemed to make it work again for a bit, but as before, actually putting more traffic through (ie: browsing a couple of pages) made it fall over completely. So then, instead of rebooting as previously, I did the following: Disable wireless networking in network manager rmmod ath9k rmmod ath rmmod mac80211 rmmod cfg80211 modprobe ath9k Re-enable wireless networking in network manager Network reconnected, and has been fine ever since. -- [ath9k] networking fails after resume from suspend or hibernate https://bugs.launchpad.net/bugs/442644 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
