Problem solved
Purchase $25 Pandex PCI-E Controller Card (USB3.1 External Type A+C, with Internal USB3.0 header connector ) which was nice to connect USB cable from the front of the case.




USB 3.0 works great images are flying to my Hard drive no freezing connects instantly.
Also, test my WiFi and it freezes once at the first time, but the same time there was an update for my Asus RT-AC66U Router so did the update and now it transfers images with no problem.
I will do the test tomorrow with the remote shooter and USB3.1 connection.

"I see!" said the blind carpenter as he picked up his hammer and saw. The evidence has stared us in the face since Friday afternoon. But I was too clueless to pick it up, and you finally beat me to it. The computer is one you built yourself, and the USB-3 port on the motherboard doesn't quite play nice with the camera. The new USB-3 interface works correctly, so the problem went away. Sorry if I led you down a couple of blind alleys.

Problem solved Part 2


This morning my WiFi connection did the same thing transfer 2 pictures and freeze I was thinking what I did differently from yesterday when everything was going so smoothly I did transfer over 600 pictures thru WiFi with no problem. IMG.jpg

And Eὕρηκα,  I found the problem!
after updating my Router I never turn ON  my VPN but in the morningn after restart  the VPN loads automatically.
So now I know the VPN causes the problems with WiFi connection and camera.


Some results for transfer 10 RAW images 653Mb total

1) WiFi to the computer on Lan (connected to router with cable) 3min 18sec  (19.8sec per image)
2) WiFi to directly to laptop not using network or router 3min 51sec  (23.1sec per image)
3) WiFI using network setting camera WiFi to router -  laptop WiFi to router 8min 24sec  (50.4sec per image) I have to find why it so long and tweak that.

4) Cable USB 3.0 17.75sec  (1.7sec per image)

5) Cable USB 2.0 27.0sec   (2.7sec per image)

The test with USB3.1 connection went completely wrong Robot Sad
I was described myself as a computer guru and I was ripped off by local computer store ??? Technician ???  This card is not USB 3.1  only USB 3.0  with USB Type C 2.4A Quick Charge green USB on the back whatever this means this port does not recognize anything just charge.
There are not USB 3.1 cards with Internal USB3.0 header so far I search.

Ok, I will slap myselff in the  head and call silly    Smiley Embarassed

Re: EOS Utility issue - Live view freeze

After using live view I find the camera computer will crash. It may crash after a few minutes or a few hours. Only way I have found to avoid this is to cycle power to the camera (NOT on/off switch), actually unplug it if using AC adapter or remove battery. 

Other issue with live view is that camera will overheat and stop working if in live view too long. 


Hope that helps.

Re: EOS Utility issue - Live view freeze

Not sure if this relate to your issue, but I had problems with live view - Worked fine on my smal Helix tablet and would not load properly on my T30s with a NVIDIA card - dissabled the NVIDIA card and works like a sharm
