Hi Vladica,
>From the 'changelog', it appears that N321 support began with release
3.14.  But, at that point I believe that WR was already broken.  So, I
think that there is no solution to your problem other than to wait for
Ettus to fix the WR issues.  However, WR has been broken for a while (note
user-list posts from last fall Sept  & Dec) so I don't know when this will
be working again.
