You misunderstood: The log entries shown were from the configuration
using the old driver whereas "r8712u" has only DHCP offers in the logs
but no ACKs.  But since you asked, "ping(8)" returns:

  From 192.168.3.1 icmp_seq=8 Destination Host Unreachable

192.168.3.1 is the IP of the wlan0 interface of the linux host acting
as the router/DNS-resolver/DHCP-provider.
