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 :)
