In the Network history graph of System Monitor, network activity over Wi-Fi shows up fine, but activity over wired ethernet doesn't show up at all. Using
lspci, my ethernet adapter shows up as follows:
02:00.0 Ethernet controller: Qualcomm Atheros AR8162 Fast Ethernet (rev 10)
Is there any way to fix this? To be absolutely clear, I am having no problems with the network connection itself, I just am unable to monitor its activity.
