First, when I using Asus original firmware, I cannot connect to my printer using Standard TCP/IP connection, but "Printer.exe" software do it's job and my printer start working. After upgrading to Merlin, this "Printer.exe" can't find any router that supports printer and my printer no longer works. But now Standard TCP/IP connection works (surprise). Everything seems to be fine except that type of connection is much slower as I see - printer waits several seconds (even 10 or more) before...
