Dears I'm using a beaglebone black to stream video over UDP. I wrote a software and have tested it using a urtwn device + webcam Logitech C920. All is connected using a USB hub with external power source. So urtwn and webcam, both are plugged in the same USB hub. When I plug the hub and run my software on a old notebook intel centrino with FreeBSD 11.0-RC2 AMD64 all works fine. Last night the system stream video all night. But, when I replace the notebook by beaglebone black running FreeBSD 11.0-RC1 with the same USB HUB, the same wrtwn device and same camera, randomly after some time the beaglebone black network shutdown and terminal shows this messages : Network is down % urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. urtwn0: ieee80211_crypto_encap returns NULL. Then, I need to run /etc/rc.d/netif stop /etc/rc.d/netif start To enable network again. So, someone can give me a hit about what can be this and how to fix? Thanks a lot []'s -Otacilio
