According to the route information that you have given below, the IP
of the router is 192.168.1.254 and your IP is 192.168.1.100

Nothing went wrong here. Solaris was able to get an IP assigned to the
card via DHCP. So far so good ! :)

Ping the following using ping -s
192.168.1.100   -> your IP
192.168.1.254   -> Your router
 208.67.222.222   -> OpenDNS.com's DNS server
 208.67.220.220   -> Another DNS server hosted at OpenDNS.com

You should be able to ping all of the above. If the openDNS servers
cannot be pinged, then perform a traceroute to find out just where
down the path your traffic is not going ahead

This page has a brief and educational description of using traceroute
http://www.pcnetcom.net/solaris.htm

Once you establish that you are able to ping the openDNS servers,
you'd have established that your internet connection is up.

Next, test your name servers:
nslookup mail.yahoo.com

You should get a the IP addresses of the yahoo mail servers.

If you don't get a name resolution, then the DNS servers are not not
working right for you.

You could simply swithc to OpenDNS anyway:
1. Edit /etc/resolv.conf to contain the following:
domain localhost.localdomain
nameserver  208.67.220.220
nameserver  208.67.222.222

2. Copy /etc/nsswitch.dns to /etc/nsswitch.conf
