Link Drop out at random times

Hi, first of all I have done some reading and only found one simular issue.

http://forums.pioneerdj.com/entries/21370783-rekordbox-1-5-4-tries-to-terminate-rekordbox-when-linked-to-cdj900-s

I have tired turning off firewall and AV disabled wirless and change over network cables. updated firmware ect everything is up to date and all possible dead spots have been changed over.

I was using 1.5.3 (earlier versions no issues)  then this issue started happening so i updated to 2.0.1 issue still happens but not so often and mostly when I'm playing from a set playlist in rekordbox. I decided to use USBs and record box and just shut down rekordbox like every hour and use it mostly for track searches other then that I stuff please help I dont know what to do and I no longer want this to happen when playing to crowds.
