if you can ping 66.249.87.99 but cannot ping www.google.com then chances are you have DNS issues (cannot resolve hostnames)
to fix, try manually editing /etc/resolv.conf and input your nameservers in there
heres a sample
Quote:; generated by /sbin/dhclient-scriptnameserver 192.168.0.1
of course, in my case, 192.168.0.1 is my nat/firewall box, but you can point that ip to your ISP's nameservers
changes to resolv.conf take place immediatly so no need to restart networking...
