Temporary solution was to use other box. Then... I pretended it was a Windoze box and did the RRR. Reinstalled Linux, same settings as before, and now everything works correctly. Of course, this is what it did originally, worked then became "busy".

I'll continue to monitor the box, and if I start getting the 'network is busy' error message again, I'll be back for any additional suggestions.

Thanks for all the previous suggestions.
