I'm running Linux Mint 17.3 on my laptop. When docked, I'm connected via Ethernet, but when I undock, I'd like not to break my ssh sessions, ongoing downloads, etc., and to use the same IP address on the Wi-Fi adapter, so that still appears the same to other machines on my network.

Bonding in mode 1, active backup, sounds exactly like what I want. I've found a number of resources online about how to set it up, but network configuration seems to vary quite a bit between distributions and even between different versions of each distribution, so that the steps for this vary quite a bit.

What's more, most of the instructions I've found rely on static configuration, like hardcoding network addresses and even WPA passwords into /etc/network/interfaces. I take my laptop to other networks, so I rely on Network Manager to store network configuration.

By googling "bond eth0 wlan0", I found a sample /etc/networking/interfaces file that more or less works, but I apparently have to disable Network Manager to keep it from doing weird things with my routing table. And while the bond is active, I can't seem to use the Network Manager applet to change Wi-Fi networks.

Network Manager 0.9.8 supports bonded interfaces, but only for Ethernet and InfiniBand connections, not for Wi-Fi.

Is there a way to bond Ethernet and Wi-Fi connections that's compatible with Network Manager?
