It could be something going wrong with routing, firewalling, nat, or something else entirely. I have several captures of sw00 and ge00 taken after the event occurs, and local udp, arp, and icmp and icmpv6 traffic is working correctly. As is multicast. The other device (sw10) stays running... What I see in the captures I have is syn attempts from the sw00 interface do make it to the internet, and syn/ack attempts do return through ge00, but do not make it through sw00. However I don't see ANY local syn attempts in the capture I have: jg or someone needs to try a local tcp connection to a local device or through the local router to a local ethernet device after having it hang... (I will keep trying to reproduce here) tcp.flags =3D=3D 0x0002 On Wed, Apr 2, 2014 at 6:48 PM, Stephen Hemminger wrote: > I am seeing wireless hang as well. > Mostly when multiple macbooks are active on 2.4g --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
