Do you enable CONFIG_SIM_NET_BRIDGE? To get the basic network, the below options are required: CONFIG_NET=y
CONFIG_NETINIT_DHCPC=y CONFIG_NETUTILS_DHCPC=y CONFIG_NET_ICMP=y CONFIG_NET_ICMP_SOCKET=y CONFIG_NET_UDP=y CONFIG_NET_UDP_BINDTODEVICE=y CONFIG_SIM_NET_BRIDGE=y CONFIG_SYSTEM_PING=y IPv6 need more options: CONFIG_NET_ICMPv6=y CONFIG_NET_ICMPv6_AUTOCONF=y CONFIG_NET_ICMPv6_SOCKET=y CONFIG_NET_IPv6=y CONFIG_SYSTEM_PING6=y Anyway, you can try the attached config which has more options to get the better network.
