Rekordbox 3.0/3.1/3.2 Emergency Loops

Greetings All

Have followed numerous other threads relating to the same issue, none seem to have a resolution, being in IT, I have also tried heaps of things:

DJM900 NXS, 2 x CDJ 2000 NXS all latest updates since new in September 2014 - Laptop purchased at same time purely for Rekordbox Link.

Wireless Off

Anti-Virus Off

BlueTooth Off

Firewall Off

Master Browser off/Registry hacking

New Hub, Cables....

Laptop DELL Inspiron 1544 - 5000 Series, re-installed Network, Wireless and Bluetooth drivers, BIOS etc, Windows 8.1... restored/rebuilt...

Tested over numerous hours of frustration, USB sticks direct are OK, but the main usage is via Laptop/Ethernet/Link containing my whole library of music... 

Just when it seems to run ok.... it loops.... sometimes 2 minutes, sometimes after 6 hours... totally random.

Please advise, if you want me to do any testing, or where to access logs to investigate further, please let me know.

11) Any other notes regarding your setup only:

One thing I havent tried is disconnecting the USB hub for HID, I will test and advise.  But should I have to?

12) Provide as much detail of the issue here:

Everything else works fine, its just Link.  Laptop is only used for DJing with Link.

I have turned all devices on Device Manager/Power Management to not go into Power Save mode - an issue I had with Traktor.

All drivers are updated.

I think the issue is laptop related, something from the ethernet port is polling, or sending a packet which drops the connection, hence the emergency loop, but not consistently.  I have checked all the pc logs, hence the Master Browser reg hack in case that was causing it, no luck.  But there is nothing to help locate where this issue could be, probably a setting under the nic adapters properties, ie duplex etc or something simple like that?  Here are my settings:

RealTek PCIe FE Family Controller:

Could you please help/advise... 

Cheers
