00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (2) I218-V
DeviceName: Onboard LAN
Subsystem: ASUSTeK Computer Inc. Ethernet Connection (2) I218-V
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0
Interrupt: pin A routed to IRQ 28
Region 0: Memory at dfd00000 (32-bit, non-prefetchable) [size=128K]
Region 1: Memory at dfd3c000 (32-bit, non-prefetchable) [size=4K]
Region 2: I/O ports at f080 [size=32]
Capabilities: <access denied>
Kernel driver in use: e1000e
Kernel modules: e1000e
I don't have a workaround but the following is what I use to help recover. It pings my gateway periodically, and if it can't it attempts to restart networking.
This issue is not limited to Realtek as it occurs on my system with an Intel ethernet controller (see https:/ /bugs.launchpad .net/ubuntu/ +source/ avahi/+ bug/1586528/ comments/ 9).
