[drats_users] 91AD issues

[Arnold Harding]

I wish I could be more specific than 'isn't happy'.  It does transmit, 
or I couldn't get pings and some chats through.  I just can't get 
anything that I believe requires handshaking through.  I can't 
transfer any files.

Yes.
I'll try the attenuator as well.

I don't believe I'm having any overload or other problems, although I 
could be.  I realize the 91 isn't built the way the 2820 is, but it 
seems as if it should be doing a lot better than it is.  I'm not able 
to really know if it's a receiving or transmitting issue, that's why 
my only statement is 'isn't happy'.  At least it isn't some obviously 
wrong setting that I completely overlooked.

Thanks, Arnold
