SFOS 18.5.2 MR-2

I loaded version18.5.2 MR-2 and found that access to my printers stopped working from wireless.  I went round and round trying to fix the problem but nothing worked.  My wireless is on a different physical port than the printers.  Version 18.5.2 MR-2 does not resolve intranet correctly.  I reloaded Version 18.5.1 MR-1 and everything works fine.
