Network disconnect after inserting USB 3 key

Question

Hi, At work, we have some DELL Inspiron 5720. We are working on windows 7 x86. We encounter some problem with the realtek network card (Realtek PCIe FE Family Controler). When i plug a USB3 stick on the port near the LAN port, the network card tells me that the network cable is disconnected. I have to turn off and on again the card to have my connection back. What i already do : update bios update USB 3 driver update chipset driver update LAN driver       Funny things : The problem doesn't appear when i use a USB 3 extension cable When i turn off and on again the card, i can ping other machine again but i can't ping the DELL laptop from other machine (firewall disable) The problem doesn't appear on windows 8.1 The problem appear on Windows 7 (fresh install) with the last driver provided by DELL or the last driver on Realtek Website The problem appear on all my DELL Inspiron 5720   does anyone have some idea to solve this problem ?   Thank's :)

plop28,

I don't see any Windows 7 32-bit drivers for this system, only Windows 7 64-bit, Windows 8 64-bit and Windows 8.1 64-bit.

It is important to install the drivers in the correct order. How to Download and Install Drivers in the Correct Order

Hi, thank you for your answer.

Actually, under Realtek Ethernet Controller Driver, there is a 32bit driver too in the package.

I'll try to install Windows 7 x64.
