I'm facing repetitive disconnections on a wired interface USB/Eth (EEM). I'm not sure the origin. How can I be sure it is or not caused by Ubuntu ?
My ethernet controller is (output of lspci): Intel Corporation 82579LM Gigabit Network Connection (rev 04)
And the USB one is : Intel Corporation 6 Series/C200 Series chipset Family USB Enhanced Host Controller #2 (rev 04)
The PC is a HP EliteBook.
What else can I check ? Do ?
Thanks for any hints...
