I just bought a new Lenovo Ideapad S410p with this ethernet card:

$ lspci -nn | grep 0200
03:00.0 Ethernet controller [0200]: Qualcomm Atheros QCA8172 Fast Ethernet [1969:10a0] (rev 10)

Both wireless and eth0 works fine, connect to internet and router no issues there.

But with any tool I used to check the traffic on it shows me zero in both up/down traffic. And this happens ONLY with the ETH0 interface, with the wireles card (another Qualcom Atheros) the traffic is showed, I searched in google with no luck, any idea about how to fix it?

Using Ubuntu 14.04 64 bits

  • What version of ubuntu are you using? If you uncheck enable wireless in network manager can you still connect to the internet with your wired connection?
