My wired and wireless networks use different IP address ranges, so I need to re-run dhclient on lagg0, but I can't get an address on it. In fact, dhclient doesn't work at all with a lagg interface when it is only backed by my wireless card. Without a lagg interface, I can get addresses on both wired and wireless cards individually and act dual-homed just fine. - Nikolai Lifanov
