Here seems that reboot in bootloader mode. I have couple of disconnect
and reconnect and I don't know if connman
send some power on/off at command and make this strange behavior. The
fact that start in bootloader mode can be a power
issue? can you try to connect using a powered HUB?

Subject: Route created for DHCP DNS server

Hi,
When a DHCP option_code 6 is received Connman adds a route to the DNS
server address.
connmand[259]: DHCP server: option_code 6 option_value 1.1.1.1
connmand[259]: wlan0 {add} route 1.1.1.1 gw 0.0.0.0 scope 253 <LINK>
The resulting routes:
$ ip route
default via 192.168.73.1 dev wlan0
1.1.1.1 dev wlan0 scope link
Because of this the DNS server is not routed trough the gateway and it
cannot be reached.
Thanks,
Nuno
