I am actually far from convinced it is actually a wifi bug. 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 == 0x0002
