Vista - Can't add, delete, or configure ports?!!

Before Vista, I had a happily configured set of two printers printing
correctly on a wireless Belkin print server via separate PC ports. Now, I
have a sadly configured set of two printers hanging off the same PC
port...and no way to add, delete, or configure ports. I just get a Vista
error message that it can't be done.

While I wait the 48 hours for a callback from a Level 3 Belkin tech...who
will likely tell me to call a Vista expert...is there anyone who can provide
insight? The PC OEM is similarly stumped,and MSFT wants $79 just to talk to
me.

Thanks!
