Host controller hangs intermitentlly when connecting to domain controller


    • NEW

      Host controller hangs intermittently when connecting to domain controller. Host controller is stuck forever and never recovers from this sistuation.

      I have never experienced this on local network, however this is pretty easy to reproduce using wireless network. The testing was done on private local wireless network with zero packet outages:

      6973 packets transmitted, 6969 received, 0% packet loss, time 25334ms
      rtt min/avg/max/mdev = 1.398/4.318/284.480/11.672 ms, pipe 15, ipg/ewma 3.633/2.775 ms

      Also, the problem seems to be affecting only connecting - once the connection is made, all the management operations are performed correctly without problems.
