Dear Maintainer,

So far the problem with network-manager is not solved. Every time if I restart
my laptop with disconnected Lan cable then Wi-Fi is connected to favorite
network but internet connection does not work. If during computer restart Lan
cable is connected then after Lan cable disconnecting Wi-Fi works well and
internet connection as well.

My laptop is Lenovo Ideapad B560

03:00.0 Ethernet controller: Qualcomm Atheros AR8131 Gigabit Ethernet (rev c0)
04:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless
Network Adapter (rev 01)

Broadcom firmware firmware-brcm80211 is installed. Used kernel version does not
have any effect for this issue.

Thanks

Ota

Most likely an issue of using managed=true (which is not the default).

I assume your eth0 is configured in /etc/network/interfaces, and
therefore configured by both ifupdown and NetworkManager. This might
result in you your default route and /etc/resolv.conf becoming messed up.

Thank you for response. But if I put managed=false then the wired is not
managed by NM and only Wi-Fi works.

/etc/network/interfaces:

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

Strange is that all was working before some NM update.
